Abstract
Placenta in certain species including the human has evolved as a highly invasive tumor-like organ invading the uterus aned its vasculature to derive oxygen and nutrients for the fetus and exchange waste products. While several excellent reviews have been written comparing hemochorial placentation with tumors, no comprehensive review is available dealing with mechanistic insights into what makes them different, and what tumor biologists can learn from placental biologists, and vice versa. In this review, we analyze the structure-function relationship of the human placenta, emphasizing the functional need of the spatio-temporally orchestrated trophoblast invasiveness for fetal development and growth, and pathological consequences of aberrant invasiveness for fetal and maternal health. We then analyze similarities and differences between the placenta and invasive tumors in terms of hallmarks of cancer, some key molecules regulating their invasive functions, and how placental cancers (choriocarcinomas) or other cancers become refractory or even addicted to these invasion-restraining molecules. We cite in vitro models of human trophoblast and choriocarcinoma cell lines utilized to study mechanisms in normal placental development as well as those responsible for tumor progression. We discuss the pathobiology of hyper-invasive placentas and show thattrophoblastic neoplasias are a unique and heterogeneous class of tumors. We delve into the questions as to why metastasis from other organs rarely occurs at the placental site and whether pregnancy makes the mother more or less vulnerable to cancer-related morbidity/mortality. We attempt to compare trophoblast stem cells and cancer stem cells. Finally, we leave the readers with some thoughts as foods of future investigations.

Moon JH, Lee SH, Lim YC. Wnt/β-catenin/Slug pathway contributes to tumor invasion and lymph node metastasis in head and neck squamous cell carcinoma. Clin Exp Metastasis 2021; 38:163-174.

Abstract
The canonical Wnt/β-catenin pathway is involved in diverse cancer development mechanisms, such as proliferation, migration, and invasion. However, its role in head and neck squamous cell carcinoma (HNSCC) remains largely unknown. We investigated whether the canonical Wnt/β-catenin signaling pathway acts as a controller of invasion and lymph node metastasis (LNM) in HNSCC. Loss of function experiments against the canonical Wnt/β-catenin pathway were conducted to evaluate its invasive and metastatic role in HNSCC cells. Slug was evaluated as a downstream protein in canonical Wnt/β-catenin-mediated invasion. In addition, canonical Wnt/β-catenin and Slug expression levels were examined in 119 HNSCC tissue samples to study the relevance of these proteins in LNM and prognosis of patients post-treatment. In vitro suppression of β-catenin expression led to decreased migration and invasion of HNSCC cells. Using an in vivo mouse orthotopic LNM model, a decrease in LNM was observed with mitigated β-catenin expression. Slug expression upregulation mediates invasion and LNM by the canonical Wnt/β-catenin pathway. Simultaneous expression of β-catenin and Slug is the major predictive factor of LNM and survival rate in patients with HNSCC. In conclusion, the canonical Wnt/β-catenin/Slug signaling axis significantly contributes to cancer cell invasion and LNM. Its blockade may be a treatment strategy for LNM and tumor recurrence in HNSCC.

Abstract
Rewiring tumor cells to undergo drug-induced apoptosis is a promising way to overcome chemoresistance. Therefore, identifying causative factors for chemoresistance is of high importance. Unbiased global proteome profiling of sensitive, early, and late cisplatin-resistant oral squamous cell carcinoma (OSCC) lines identified CMTM6 as a top-ranked upregulated protein. Analyses of OSCC patient tumor samples demonstrated significantly higher CMTM6 expression in chemotherapy (CT) nonresponders as compared with CT responders. In addition, a significant association between higher CMTM6 expression and poorer relapse-free survival in esophageal squamous cell carcinoma, head and neck squamous cell carcinoma, and lung squamous cell carcinoma was observed from Kaplan-Meier plot analysis. Stable knockdown (KD) of CMTM6 restored cisplatin-mediated cell death in chemoresistant OSCC lines. Upon CMTM6 overexpression in CMTM6-KD lines, the cisplatin-resistant phenotype was rescued. The patient-derived cell xenograft model of chemoresistant OSCC displaying CMTM6 depletion restored the cisplatin-induced cell death and tumor burden substantially. The transcriptome analysis of CMTM6-KD and control chemoresistant cells depicted enrichment of the Wnt signaling pathway. We demonstrated that CMTM6 interaction with membrane-bound Enolase-1 stabilized its expression, leading to activation of Wnt signaling mediated by AKT–glycogen synthase kinase-3β. CMTM6 has been identified as a stabilizer of programmed cell death ligand 1. Therefore, as CMTM6 facilitates tumor cells for immune evasion and mediates cisplatin resistance, it could be a promising therapeutic target for treating therapy-resistant OSCC.

Genome-wide association studies detects candidate genes for wool traits by re-sequencing in Chinese fine-wool sheep. BMC Genomics 2021; 22:127. [PMID: 33602144 PMCID: PMC7893944 DOI: 10.1186/s12864-021-07399-3] [Citation(s) in RCA: 14] [Impact Index Per Article: 4.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/27/2020] [Accepted: 01/19/2021] [Indexed: 12/15/2022] Open
Abstract
BACKGROUND The quality and yield of wool determine the economic value of the fine-wool sheep. Therefore, discovering markers or genes relevant to wool traits is the cornerstone for the breeding of fine-wool sheep. In this study, we used the Illumina HiSeq X Ten platform to re-sequence 460 sheep belonging to four different fine-wool sheep breeds, namely, Alpine Merino sheep (AMS), Chinese Merino sheep (CMS), Aohan fine-wool sheep (AHS) and Qinghai fine-wool sheep (QHS). Eight wool traits, including fiber diameter (FD), fiber diameter coefficient of variance (FDCV), fiber diameter standard deviation (FDSD), staple length (SL), greasy fleece weight (GFW), clean wool rate (CWR), staple strength (SS) and staple elongation (SE) were examined. A genome-wide association study (GWAS) was performed to detect the candidate genes for the eight wool traits. RESULTS A total of 8.222 Tb of raw data was generated, with an average of approximately 8.59X sequencing depth. After quality control, 12,561,225 SNPs were available for analysis. And a total of 57 genome-wide significant SNPs and 30 candidate genes were detected for the desired wool traits. Among them, 7 SNPs and 6 genes are related to wool fineness indicators (FD, FDCV and FDSD), 10 SNPs and 7 genes are related to staple length, 13 SNPs and 7 genes are related to wool production indicators (GFW and CWR), 27 SNPs and 10 genes associated with staple elongation. Among these candidate genes, UBE2E3 and RHPN2 associated with fiber diameter, were found to play an important role in keratinocyte differentiation and cell proliferation. Gene ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment results, revealed that multitude significant pathways are related to keratin and cell proliferation and differentiation, such as positive regulation of canonical Wnt signaling pathway (GO:0090263). CONCLUSION This is the first GWAS on the wool traits by using re-sequencing data in Chinese fine-wool sheep. The newly detected significant SNPs in this study can be used in genome-selective breeding for the fine-wool sheep. And the new candidate genes would provide a good theoretical basis for the fine-wool sheep breeding.

Portrait of Cancer Stem Cells on Colorectal Cancer: Molecular Biomarkers, Signaling Pathways and miRNAome. Int J Mol Sci 2021; 22:1603.

Abstract
Colorectal cancer (CRC) is a leading cause of cancer death worldwide, and about 20% is metastatic at diagnosis and untreatable. Increasing evidence suggests that the heterogeneous nature of CRC is related to colorectal cancer stem cells (CCSCs), a small cells population with stemness behaviors and responsible for tumor progression, recurrence, and therapy resistance. Growing knowledge of stem cells (SCs) biology has rapidly improved uncovering the molecular mechanisms and possible crosstalk/feedback loops between signaling pathways that directly influence intestinal homeostasis and tumorigenesis. The generation of CCSCs is probably connected to genetic changes in members of signaling pathways, which control self-renewal and pluripotency in SCs and then establish function and phenotype of CCSCs. Particularly, various deregulated CCSC-related miRNAs have been reported to modulate stemness features, controlling CCSCs functions such as regulation of cell cycle genes expression, epithelial-mesenchymal transition, metastasization, and drug-resistance mechanisms. Primarily, CCSC-related miRNAs work by regulating mainly signal pathways known to be involved in CCSCs biology. This review intends to summarize the epigenetic findings linked to miRNAome in the maintenance and regulation of CCSCs, including their relationships with different signaling pathways, which should help to identify specific diagnostic, prognostic, and predictive biomarkers for CRC, but also develop innovative CCSCs-targeted therapies.

Kynurenine 3-monooxygenase upregulates pluripotent genes through β-catenin and promotes triple-negative breast cancer progression. EBioMedicine 2021; 54:102717. [PMID: 32268268 PMCID: PMC7191260 DOI: 10.1016/j.ebiom.2020.102717] [Citation(s) in RCA: 13] [Impact Index Per Article: 4.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/15/2019] [Revised: 02/27/2020] [Accepted: 02/28/2020] [Indexed: 12/27/2022] Open
Abstract
Background Triple-negative breast cancer (TNBC) is aggressive and has a poor prognosis. Kynurenine 3-monooxygenase (KMO), a crucial kynurenine metabolic enzyme, is involved in inflammation, immune response and tumorigenesis. We aimed to study the role of KMO in TNBC. Methods KMO alteration and expression data from public databases were analyzed. KMO expression levels in TNBC samples were analyzed using immunohistochemistry. Knockdown of KMO in TNBC cells was achieved by RNAi and CRISPR/Cas9. KMO functions were examined by MTT, colony-forming, transwell migration/invasion, and mammosphere assays. The molecular events were analyzed by cDNA microarrays, Western blot, quantitative real-time PCR and luciferase reporter assays. Tumor growth and metastasis were detected by orthotopic xenograft and tail vein metastasis mouse models, respectively. Findings KMO was amplified and associated with worse survival in breast cancer patients. KMO expression levels were higher in TNBC tumors compared to adjacent normal mammary tissues. In vitro ectopic KMO expression increased cell growth, colony and mammosphere formation, migration, invasion as well as mesenchymal marker expression levels in TNBC cells. In addition, KMO increased pluripotent gene expression levels and promoter activities in vitro. Mechanistically, KMO was associated with β-catenin and prevented β-catenin degradation, thereby enhancing the transcription of pluripotent genes. KMO knockdown suppressed tumor growth and the expression levels of β-catenin, CD44 and Nanog. Furthermore, mutant KMO (known with suppressed enzymatic activity) could still promote TNBC cell migration/invasion. Importantly, mice bearing CRISPR KMO-knockdown TNBC tumors showed decreased lung metastasis and prolonged survival. Interpretation KMO regulates pluripotent genes via β-catenin and plays an oncogenic role in TNBC progression.

Abstract
Pre-clinical and clinical studies revealed that mesenchymal stromal cell (MSC) transplants elicit tissue repair. Conditioning MSC prior to transplantation may boost their ability to support repair. We investigated macrophage-derived inflammation as a means to condition MSC by comprehensively analyzing their transcriptome and secretome. Conditioning MSC with macrophage-derived inflammation resulted in 3208 differentially expressed genes, which were annotated with significantly enriched GO terms for 1085 biological processes, 85 cellular components, and 79 molecular functions. Inflammation-mediated conditioning increased the secretion of growth factors that are key for tissue repair, including vascular endothelial growth factor, hepatocyte growth factor, nerve growth factor and glial-derived neurotrophic factor. Furthermore, we found that inflammation-mediated conditioning induces transcriptomic changes that challenge the viability and mobility of MSC. Our data support the notion that macrophage-derived inflammation stimulates MSC to augment their paracrine repair-supporting activity. The results suggest that inflammatory pre-conditioning enhances the therapeutic potential of MSC transplants.

Understanding the role of integrins in breast cancer invasion, metastasis, angiogenesis, and drug resistance. Oncogene 2021; 40:1043-1063.

Abstract
Integrins are cell adhesion receptors, which are typically transmembrane glycoproteins that connect to the extracellular matrix (ECM). The function of integrins regulated by biochemical events within the cells. Understanding the mechanisms of cell growth by integrins is important in elucidating their effects on tumor progression. One of the major events in integrin signaling is integrin binding to extracellular ligands. Another event is distant signaling that gathers chemical signals from outside of the cell and transmit the signals upon cell adhesion to the inside of the cell. In normal breast tissue, integrins function as checkpoints to monitor effects on cell proliferation, while in cancer tissue these functions altered. The combination of tumor microenvironment and its associated components determines the cell fate. Hypoxia can increase the expression of several integrins. The exosomal integrins promote the growth of metastatic cells. Expression of certain integrins is associated with increased metastasis and decreased prognosis in cancers. In addition, integrin-binding proteins promote invasion and metastasis in breast cancer. Targeting specific integrins and integrin-binding proteins may provide new therapeutic approaches for breast cancer therapies. This review will examine the current knowledge of integrins' role in breast cancer.

Abstract
Glioblastoma multiforme (GBM) is the most common form of brain cancer and one of the most aggressive cancers found in humans. Most of the signs and symptoms of GBM can be mild and slowly aggravated, although other symptoms might demonstrate it as an acute ailment. However, the precise mechanisms of the development of GBM remain unknown. Due to the improvement of molecular pathology, current researches have reported that glioma progression is strongly connected with different types of epigenetic phenomena, such as histone modifications, DNA methylation, chromatin remodeling, and aberrant microRNA. Furthermore, the genes and the proteins that control these alterations have become novel targets for treating glioma because of the reversibility of epigenetic modifications. In some cases, gene mutations including P16, TP53, and EGFR, have been observed in GBM. In contrast, monosomies, including removals of chromosome 10, particularly q23 and q25-26, are considered the standard markers for determining the development and aggressiveness of GBM. Recently, amid the epigenetic therapies, histone deacetylase inhibitors (HDACIs) and DNA methyltransferase inhibitors have been used for treating tumors, either single or combined. Specifically, HDACIs are served as a good choice and deliver a novel pathway to treat GBM. In this review, we focus on the epigenetics of GBM and the consequence of its mutations. We also highlight various treatment approaches, namely gene editing, epigenetic drugs, and microRNAs to combat GBM.

Abstract
Cancer stem cells (CSCs), also known as tumor-initiating cells, are a sub-population of tumor cells found in many human cancers that are endowed with self-renewal and pluripotency. CSCs may be more resistant to conventional anticancer therapies than average cancer cells, as they can easily escape the cytotoxic effects of standard chemotherapy, thereby resulting in tumor relapse. Despite significant progress in related research, effective elimination of CSCs remains an unmet clinical need. CSCs are localized in a specialized microenvironment termed the niche, which plays a pivotal role in cancer multidrug resistance. The niche components of CSCs, such as the extracellular matrix, also physically shelter CSCs from therapeutic agents. Colorectal cancer is the most common malignancy worldwide and presents a relatively transparent process of cancer initiation and development, making it an ideal model for CSC niche research. Here, we review recent advances in the field of CSCs using colorectal cancer as an example to illustrate the potential therapeutic value of targeting the CSC niche. These findings not only provide a novel theoretical basis for in-depth discussions on tumor occurrence, development, and prognosis evaluation, but also offer new strategies for the targeted treatment of cancer.

Abstract
Over the last decades, the cancer survival rate has increased due to personalized therapies, the discovery of targeted therapeutics and novel biological agents, and the application of palliative treatments. Despite these advances, tumor resistance to chemotherapy and radiation and rapid progression to metastatic disease are still seen in many patients. Evidence has shown that cancer stem cells (CSCs), a sub-population of cells that share many common characteristics with somatic stem cells (SSCs), contribute to this therapeutic failure. The most critical properties of CSCs are their self-renewal ability and their capacity for differentiation into heterogeneous populations of cancer cells. Although CSCs only constitute a low percentage of the total tumor mass, these cells can regrow the tumor mass on their own. Initially identified in leukemia, CSCs have subsequently been found in cancers of the breast, the colon, the pancreas, and the brain. Common genetic and phenotypic features found in both SSCs and CSCs, including upregulated signaling pathways such as Notch, Wnt, Hedgehog, and TGF-β. These pathways play fundamental roles in the development as well as in the control of cell survival and cell fate and are relevant to therapeutic targeting of CSCs. The differences in the expression of membrane proteins and exosome-delivered microRNAs between SSCs and CSCs are also important to specifically target the stem cells of the cancer. Further research efforts should be directed toward elucidation of the fundamental differences between SSCs and CSCs to improve existing therapies and generate new clinically relevant cancer treatments.

Abstract
BACKGROUND Keratin-associated protein (KAP), the structural protein molecule of hair fibers, plays a key role in determining the physical properties of hair. Studies of Krtap11-1 have focused only on its localization. Functional studies of Krtap11-1 in hair follicle development have so far not been reported. OBJECTIVE This study aimed to provide evidence for the role of Krtap11-1 in skin and hair development. METHODS Full-length cloning and analysis of Krtap11-1 were conducted to ascertain its function. Overexpression vectors and interference sequences were constructed and transfected into RAB-9 cells. Quantitative real-time polymerase chain reaction (qRT-PCR) was used to investigate the hair follicle developmental stage of Krtap11-1, the expression of different tissues, and the effects on other hair follicle development-related genes. RESULTS The full length of cloned Krtap11-1 was 947 bp. Krtap11-1 was confirmed to be a hydrophilic protein localized mostly in mitochondria. The greatest mRNA expression was observed in skin. Using a follicle synchronization model, it was found that Krtap11-1 mRNA expression levels first increased then decreased over the passage of time, principally during hair follicle catagen and telogen. Following the overexpression of Krtap11-1, mRNA expression levels of the WNT-2, KRT17, BMP-2, and TGF-β-1 genes increased, and LEF-1 decreased (P < 0.05), the converse after the corresponding use of si-RNA interference. CONCLUSIONS Krtap11-1 exerts a promoting effect. The results provide novel insight into the relationship between hair follicle development and Krtap11-1 gene expression.

Abstract
Aging is characterized by the accumulation of DNA damage and a decrease in stem cell functionality, yet molecular mechanisms that limit the maintenance of stem cells in response to DNA damage remain to be delineated. Here we show in mouse models that DNA damage leads to a transient over-activation of Wnt signaling in hematopoietic stem cells (HSCs), and that high activity of canonical Wnt/β-catenin signaling sensitizes HSCs to DNA damage induced by X-irradiation which results in preferential maintenance of HSCs with low levels of Wnt signaling. The study shows that genetic or chemical activation of canonical Wnt signaling enhances radiosensitivity of HSCs while inhibition of Wnt signaling decreases it. Together, these results indicate that levels of Wnt signaling activity mediate heterogeneity in the sensitivity of HSCs to DNA damage induced depletion. These findings could be relevant for molecular alterations and selection of stem cells in the context of DNA damage accumulation during aging and cancer formation.

Abstract
Psoriasis is a chronic, local as well as a systemic, inflammatory skin condition. Psoriasis influences the quality of life up to 3.8% of the population and occurs often between 15 and 30 years of age. Specific causes are linked to psoriasis, including the interleukin IL-23/IL-17 Axis, human antigen leucocyte (HLA), and tumor necrosis factor-α (TNF-α). Secukinumab is a monoclonal antibody that specifically binds and neutralizes IL-17A required in the treatment of Psoriasis. The signaling pathways of Wnt govern multiple functions of cell-like fate specification, proliferation, polarity, migration, differentiation with their signaling controlled rigorously, given that dysregulation caused by various stimuli, can lead to alterations in cell proliferation, apoptosis, and human inflammatory disease. Current data has supported non-canonical Wnt signaling pathways in psoriasis development, particularly Wnt5a activated signaling cascades. These interconnected factors are significant in interactions between immune cells, keratinocytes, and inflammatory factors due to a higher degree of transglutaminase 2, mediated by activation of the keratinocyte hyperproliferation of the psoriatic patient's epidermis. This study discusses the pathology of Wnt5a signaling and its involvement in the epidermal inflammatory effects of psoriasis with other related pathways.

Abstract
The theory of cancer stem cells (CSCs) proposes that the different cells within a tumor, as well as metastasis deriving from it, are originated from a single subpopulation of cells with self-renewal and differentiation capacities. These cancer stem cells are supposed to be critical for tumor expansion and metastasis, tumor relapse and resistance to conventional therapies, such as chemo- and radiotherapy. The acquisition of these abilities has been attributed to the activation of alternative pathways, for instance, WNT, NOTCH, SHH, PI3K, Hippo, or NF-κB pathways, that regulate detoxification mechanisms; increase the metabolic rate; induce resistance to apoptotic, autophagic, and senescence pathways; promote the overexpression of drug transporter proteins; and activate specific stem cell transcription factors. The elimination of CSCs is an important goal in cancer therapeutic approaches because it could decrease relapses and metastatic dissemination, which are main causes of mortality in oncology patients. In this work, we discuss the role of these signaling pathways in CSCs along with their therapeutic potential.

Abstract
Non-small-cell lung cancer (NSCLC) is the most prevalent form of lung cancer and has a poor five-year survival rate of 15%. Chemotherapy and targeted therapies have significantly improved patients' prognosis. Nevertheless, after a successful initial response, some patients relapse when cancer cells become resistant to drug treatments, representing an important clinical limitation. Therefore, investigating the mechanisms of drug resistance is of significant importance. Recently, considerable attention has been given to long non-coding RNAs (lncRNAs), a heterogeneous class of regulatory molecules that play essential roles in tumorigenesis by modulating genes and signalling pathways involved in cell growth, metastasis and drug response. In this article, we review recent research findings on the role of lncRNAs in drug resistance in NSCLC, highlighting their mechanisms of action.

Abstract
Cancer stem cells (CSCs) are a small part of cancer cells inside the tumor that have similar characteristics to normal stem cells. CSCs stimulate tumor initiation and progression in a variety of cancers. Several transcription factors such as NANOG, SOX2, and OCT4 maintain the characteristics of CSCs and their upregulation is seen in many malignancies resulting in increased metastasis, invasion, and recurrence. Among these factors, NANOG plays an important role in regulating the self-renewal and pluripotency of CSCs and the clinical significance of NANOG has been suggested as a marker of CSCs in many cancers. The up and down-regulation of NANOG is associated with several important signaling pathways, including JAK/STAT, Wnt/β-catenin, Notch, TGF-β, Hedgehog, and several microRNAs (miRNAs). In this review, we will investigate the function of NANOG in CSCs and the molecular mechanism of its regulation by signaling pathways and miRNAs. We will also investigate targeting NANOG with different techniques, which is a promising treatment strategy for cancer treatment.

Abstract
Gastric cancer (GC) is among the most treatment-refractory epithelial malignancies. Aberrant activation of Wnt/β-catenin-signaling has been implicated in a variety of human cancers, including gastric cancer. Here we report that the elevated expression of lymphoid enhancer binding factor 1 (Lef1) is associated with the TNM (tumor- node-metastasis) stage of gastric cancer. Subsequently, 2,4-diamino-quinazoline (2,4-DAQ), a selective inhibitor of Lef1, was identified to suppress the expression of Wnt/β-catenin target genes such as AXIN2, MYC and LGR5 and result in the suppression of gastric cancer cell growth through the apoptotic pathway. The 2,4-DAQ also exhibited an inhibitory effect on the migration/invasion of gastric cancer cells. Importantly, the treatment of human gastric tumor xenograft with 2,4-DAQ suppressed tumor growth in a nude mouse model. Furthermore, 2,4-DAQ appears effective on patient-derived organoids (PDOs). Transcriptome sequencing analysis also revealed that 2,4-DAQ are more effective on the gastric cancers that exhibit higher expression levels of Wnt-signaling pathway-related genes than their adjacent normal gastric tissues.

Abstract
Stem cell aging underlies aging-associated disorders, such as steeply increased incidences of tumors and impaired regeneration capacity upon stress. However, whether and how the intestinal stem cells age remains largely unknown. Here we show that intestinal stem cells derived from 24-month-old mice hardly form typical organoids with crypt-villus structures, but rather mainly form big, rounded cysts devoid of differentiated cell types, which mimics the culturing of heterozygous APC-deficient cells from the APCmin mouse line. Further analysis showed that cultured crypts derived from aged mice exhibited reduced expression levels of differentiation genes and higher expression of Wnt target genes. Lowering the concentration of R-spondin-1 in the culture system significantly reduced formation of rounded cysts, accompanied by an increased formation of organoids from crypts derived from old mice. We are the first to uncover that intestinal stem cells derived from old mice harbor significant deficiency in differentiation that can be partially rescued through a reduction in R-spondin-1 exposure. This could be highly relevant to intestinal tumor development and the reduced regeneration potential observed in the aged population. Our study provides the first experimental evidence that an over-responsiveness to Wnt/beta-catenin signaling of aged intestinal stem cells mediates the aging-induced deficiency in differentiation, and could serve as a potential target to ameliorate aging-associated intestinal pathologies.

Abstract
Cancer stem cells are critical for cancer initiation, development, and treatment resistance. Our understanding of these processes, and how they relate to glioblastoma heterogeneity, is limited. To overcome these limitations, we performed single-cell RNA sequencing on 53586 adult glioblastoma cells and 22637 normal human fetal brain cells, and compared the lineage hierarchy of the developing human brain to the transcriptome of cancer cells. We find a conserved neural tri-lineage cancer hierarchy centered around glial progenitor-like cells. We also find that this progenitor population contains the majority of the cancer's cycling cells, and, using RNA velocity, is often the originator of the other cell types. Finally, we show that this hierarchal map can be used to identify therapeutic targets specific to progenitor cancer stem cells. Our analyses show that normal brain development reconciles glioblastoma development, suggests a possible origin for glioblastoma hierarchy, and helps to identify cancer stem cell-specific targets.

Abstract
Purpose We aim to investigate the role of Golgi phosphoprotein 3 (GOLPH3) and the possible regulation mechanism underlying lung adenocarcinoma (LADC). Methods The level of GOLPH3 was performed by quantitative real time (qRT)-PCR, Western blot and immunohistochemistry. Patient survival rate was analyzed by Kaplan–Meier method. MTT was used to detect cell viability. The levels of p-serine/threonine-protein kinase (Akt), Akt, p-p65, p65 and β-catenin were determined by Western blot. Cell apoptosis was tested using flow cytometry. Angiogenesis was determined by in vitro angiogenesis assay. qPCR and Western blot were performed to identify apoptotic protein B-cell lymphoma 2 (Bcl-2)/Bcl-2-associated X protein (Bax) and vascular endothelial growth factor (VEGF). Results GOLPH3 was highly expressed in LADC cell lines and tissues and was significantly correlated with poor overall survival among patients with LADC. Furthermore, GOLPH3 expression was reduced in A549 and H23 cells in a cisplatin-dependent manner. Silencing of GOLPH3 enhanced inhibition of A549 and H23 cells by cisplatin and suppressed the protein expression of p-Akt, while p-p65 expression remained stable. However, overexpression of GOLPH3 weakened the inhibition of A549 and H23 cells by cisplatin and improved the protein expression of p-Akt, while p-p65 expression remained stable. XAV939, an inhibitor of Wnt/β-catenin signaling pathway, decreased GOLPH3 overexpression-induced proliferation and enhanced cisplatin-induced angiogenesis inhibition and apoptosis, which was supported by the changes of VEGF, Bax and Bcl-2. Conclusion GOLPH3 promotes proliferation capacity in LADC through activating the Wnt/β-catenin signaling pathway.

Abstract
Gastrointestinal (GI) cancers are one of the most common forms of malignancies and still are the most important cause of cancer-related mortality worldwide. Autophagy is a conserved catabolic pathway involving lysosomal degradation and recycling of whole cellular components, which is essential for cellular homeostasis. For instance, it acts as a pivotal intracellular quality control and repair mechanism but also implicated in cell reformation during cell differentiation and development. Indeed, GI cancer stem cells (CSCs) are thought to be responsible for tumour initiation, traditional therapies resistance, metastasis and tumour recurrence. Molecular mechanisms of autophagy in normal vs CSCs gain great interest worldwide. Here, we shed light on the role of autophagy in normal stem cells differentiation for embryonic progression and its role in maintaining the activity and self-renewal capacity of CSCs which offer novel viewpoints on promising cancer therapeutic strategies based on the differential roles of autophagy in CSCs.

Abstract
Breast cancer with various biological diversity known as the common reason of death in the world and despite progress in novel therapeutic approaches, it faced with failure and recurrence in general. Recent clinical and preclinical statistics support cancer stem cells (CSCs) hypothesis and its similarities with normal stem cells. Evaluation of related paper conclude in significance finding in the further characterization of CSCs biology such as surface biomarkers, microenvironment regulatory molecules, cell signaling pathways, cell to cell transition and drug efflux pumps to overcome multidrug resistance and effective therapy. Emerging novel data indicate biological concepts in the base of unsuccessful treatment. A powerful understanding of the cell signaling pathways in cancer and CSCs topics can be led us to define and control treatment problems in cancer. More recently nano medicine based on drug delivery system modification and new implications on combinatorial therapy have been used to treat breast cancer effectively. The aim of this review is focus on CSCs as a potential target of cancer therapy, to overcome the limitation and problems of current therapeutic strategies in cancer.

Abstract
Retrotransposons copy their sequences via an RNA intermediate, followed by reverse transcription into cDNA and random insertion, into a new genomic locus. New retrotransposon copies may lead to cell transformation and/or tumorigenesis through insertional mutagenesis. Methylation is a major defense mechanism against retrotransposon RNA expression and retrotransposition in differentiated cells, whereas stem cells are relatively hypo-methylated. Epithelial-to-mesenchymal transition (EMT), which transforms normal epithelial cells into mesenchymal-like cells, also contributes to tumor progression and tumor metastasis. Cancer stem cells (CSCs), a fraction of undifferentiated tumor-initiating cancer cells, are reciprocally related to EMT. In the present study, the outcome of long terminal repeat (LTR)-Viral-Like 30 (VL30) retrotransposition was examined in mouse mammary stem-like/progenitor HC11 epithelial cells. The transfection of HC11 cells with a VL30 retrotransposon, engineered with an EGFP-based retrotransposition cassette, elicited a higher retrotransposition frequency in comparison to differentiated J3B1A and C127 mouse mammary cells. Fluorescence microscopy and PCR analysis confirmed the specificity of retrotransposition events. The differentiated retrotransposition-positive cells retained their epithelial morphology, while the respective HC11 cells acquired mesenchymal features associated with the loss of E-cadherin, the induction of N-cadherin, and fibronectin and vimentin protein expression, as well as an increased transforming growth factor (TGF)-β1, Slug, Snail-1 and Twist mRNA expression. In addition, they were characterized by cell proliferation in low serum, and the acquisition of CSC-like properties indicated by mammosphere formation under anchorage-independent conditions. Mammospheres exhibited an increased Nanog and Oct4 mRNA expression and a CD44+/CD24−/low antigenic phenotype, as well as self-renewal and differentiation capacity, forming mammary acini-like structures. DNA sequencing analysis of retrotransposition-positive HC11 cells revealed retrotransposed VL30 copies integrated at the vicinity of EMT-, cancer type- and breast cancer-related genes. The inoculation of these cells into Balb/c mice produced cytokeratin-positive tumors containing pancytokeratin-positive cells, indicative of cell invasion features. On the whole, the findings of the present study demonstrate, for the first time, to the best of our knowledge, that stem-like epithelial HC11 cells are amenable to VL30 retrotransposition associated with the induction of EMT and CSC generation, leading to tumorigenesis.

Abstract
Liver cancer stem cells (LCSCs) play a critical role in hepatocellular carcinoma (HCC) by virtue of their aggressive behavior and association with poor prognoses. Aquaporin-9 (AQP9) is a transmembrane protein that transports water and reportedly transports H2O2. Recent studies have shown that AQP9 expression has a negative effect on HCC cell invasion by inhibiting the epithelial-to-mesenchymal transition. However, the role of AQP9 in LCSCs remains obscure. We performed spheroid formation assay and flow cytometric analysis to investigate LCSCs stemness. CD133+ and CD133- cells were isolated by flow cytometry. Real-time quantitative PCR (qRT-PCR), Western blot analysis, and immunofluorescence assay were used to estimate gene expression. The protein association of β-catenin with TCF4 and the interaction of β-catenin with FOXO3a were detected by immunoprecipitation (IP). Here, we found that AQP9 was preferentially decreased in LCSCs. Upregulated AQP9 significantly suppressed LCSCs stemness. In contrast, the inhibition of AQP9 had the opposite effect. Mechanistically, AQP9 was shown to be downregulated by insulin-like growth factor 2 (IGF2), which was widely reported to contribute to maintaining CSCs stemness. Furthermore, AQP9 overexpression was found to result in reactive oxygen species (ROS) accumulation, which inhibited β-catenin activity by attenuating the interaction of β-catenin with TCF4 while concurrently enhancing the association of β-catenin with FOXO3a, ultimately inhibiting LCSCs stemness. Our study implies that stimulation of the AQP9 signaling axis may be a novel preventive and/or therapeutic approach for eliminating LCSCs. IMPLICATIONS: Our findings demonstrate that AQP9 signaling axis may be a novel preventive and/or therapeutic approach for eliminating LCSCs.

Abstract
Cervical cancer (CC) is the fourth most common type of cancer that affects women. Compared to other types of cancer, CC has a high mortality rate in women worldwide. Several factors contribute to the development of CC, but persistent high-risk human papillomavirus infection is the main etiologic agent associated with the development of CC. Moreover, several studies reported that alterations in the expression of transcription factors present in a small subpopulation of cells within tumors called cancer stem cells (CSCs), which contribute to the development of CC by promoting tumorigenicity and metastasis. These transcription factors affect self-renewal and maintenance of pluripotency and differentiation in stem cells. OCT3/4 belongs to the family of transcription factors with the POU domain. It consists of five exons and can be edited by alternative splicing into three main transcripts: OCT3/4A, OCT3/4B, and OCT3/4B1. The OCT3/4 expression in CSCs promotes carcinogenesis and the development of malignant tumors, and the loss of expression leads to the loss of self-renewal and proliferation and favors apoptosis. This review describes the main roles of OCT3/4 in CC and its importance in several biological processes that contribute to the development of CC and may serve as molecular targets to improve prognosis of CC.

Abstract
Estrogen receptor (ER) positive breast cancers often contain subpopulations of cells that express the intermediate filament protein cytokeratin 5 (CK5). CK5+ cells are enriched in cancer stem cell (CSC) properties, can be induced by progestins, and predict poor prognosis in ER+ breast cancer. We established through CK5 knockout and overexpression in ER+ breast cancer cell lines that CK5 is important for tumorsphere formation, prompting us to speculate that CK5 has regulatory activity in CSCs. To interrogate CK5 interacting proteins that may be functionally cooperative, we performed immunoprecipitation-mass spectrometry for CK5 in ER+ breast cancer cells. Focusing on proteins with signaling activity, we identified β-catenin, a key transcription factor of the Wnt signaling pathway and cell adhesion molecule, as a CK5 interactor, which we confirmed by co-immunoprecipitation in several breast cancer models. We interrogated the dual functions of β-catenin in relation to CK5. Knockout or knockdown of CK5 ablated β-catenin transcriptional activity in response to progestins and Wnt stimuli. Conversely, CK5 induced by progestins or overexpression was sufficient to promote loss of β-catenin at the cell membrane and total E-cadherin loss. A breast cancer patient-derived xenograft showed similar loss of membrane β-catenin and E-cadherin in CK5+ but not intratumoral CK5− cells and single cell RNA sequencing found the top enriched pathways in the CK5+ cell cluster were cell junction remodeling and signaling. This report highlights that CK5 actively remodels cell morphology and that blockade of CK5-β-catenin interaction may reverse the detrimental properties of CK5+ breast cancer cells.

Abstract
Aldosterone-producing adenomas (APA) is one of the causative factors of primary aldosteronism. Previous studies have suggested that there are somatic CTNNB1 mutations in APA, but the specific mechanism of CTNNB1 mutation in APA tumorigenesis and aldosterone secretion remains unclear. In the present study, human adrenocortical carcinoma cell line H295 R was used to establish stable CTNNB1 knockdown cell lines. Cell proliferation and aldosterone secretion of H295 R cells in response to angiotensin Ⅱ (Agn Ⅱ) were analyzed. We found that CTNNB1 knockdown reduced β-catenin expression and inhibited proliferation of H295 R cells. CTNNB1 knockdown inhibited Wnt/β-catenin signaling pathway and downregulated expression of downstream genes including axin 2, lymphoid enhancer binding factor 1 (LEF1), and cyclin D1. In addition, CTNNB1 knockdown decreased responses of H295 R cells to Agn Ⅱ and decreased aldosterone secretion. Our findings suggest that CTNNB1 knockdown can inhibit H295 R cell proliferation and decrease aldosterone secretion in the responses of H295 R cells to Ang II through inhibiting Wnt/β-catenin signaling pathway, indicating that targeting Wnt/β-catenin signaling pathway may be an important approach to decrease aldosterone secretion in the treatment of aldoster-producing adenomas.

Abstract
Evodiamine, an alkaloid contained in traditional Asian herbal medicines that have been used for hundreds years, is interesting due to its cytotoxic effects against many cancers. We examined the effect of evodiamine on the cancer stem cell (CSC) population and the bulk cultured cancer cells (BCC) of colon cancers to examine the double targeting effect. We found that three colon cancer cell lines’ BCC and CSC are effectively targeted by evodiamine. Evodiamine was able to suppress BCC proliferation and induce apoptosis of the cells captured in G2/M phase, as previously reported. However, evodiamine did not cause the accumulation of CSCs at a certain stage of the cell cycle, resulting in the elimination of stemness through an unknown mechanism. By analyzing the expression of 84 genes related to CSCs in two colon cancer cell lines’ CSC, as well as performing further informatics analyses, and quantitative RT-PCR analyses of 24 CSC genes, we found that evodiamine suppressed the expression of the genes that control key signaling pathways of CSC, namely, WNT and NOTCH signaling, to lead CSC elimination. These results suggest that evodiamine should be further developed for targeting both BCCs and CSCs in colon cancers.

Transcriptome Characterization of Reverse Development in Turritopsis dohrnii (Hydrozoa, Cnidaria). G3-GENES GENOMES GENETICS 2019; 9:4127-4138.

Abstract
Medusae of Turritopsis dohrnii undergo reverse development in response to physical damage, adverse environmental conditions, or aging. Senescent, weakened or damaged medusae transform into a cluster of poorly differentiated cells (known as the cyst stage), which metamorphose back into a preceding life cycle stage, the polyp. During the metamorphosis, cell transdifferentiation occurs. The cyst represents the intermediate stage between a reverting medusa and a healthy polyp, during which cell transdifferentiation and tissue reorganization take place. Here we characterize and compare the transcriptomes of the polyp and newborn medusa stages of T. dohrnii with that of the cyst, to identify biological networks potentially involved in the reverse development and transdifferentiation processes. The polyp, medusa and cyst of T. dohrnii were sequenced through Illumina RNA-sequencing and assembled using a de novo approach, resulting in 92,569, 74,639 and 86,373 contigs, respectively. The transcriptomes were annotated and comparative analyses among the stages identified biological networks that were significantly over-and under-expressed in the cyst as compared to the polyp and medusa stages. Biological processes that occur at the cyst stage such as telomerase activity, regulation of transposable elements and DNA repair systems, and suppression of cell signaling pathways, mitotic cell division and cellular differentiation and development may be involved in T. dohrnii's reverse development and transdifferentiation. Our results are the first attempt to understand T. dohrnii's life-cycle reversal at the genetic level, and indicate possible avenues of future research on developmental strategies, cell transdifferentiation, and aging using T. dohrnii as a non-traditional in vivo system.

Abstract
Matrix metalloproteinases (MMPs) have been implicated in EMT but their role in the regulation of cigarette smoke-induced EMT in airway epithelium is not clear. We have therefore investigated the potential role of MMP-2 and -9 in cigarette smoke extract (CSE) induced EMT using A549 lung epithelial cells and human small airway epithelial cells (SAEC). The cells were treated with different concentration of CSE, and MTT and trypan blue assays, acridine orange-ethidium bromide assay, gelatin zymography, Western blotting, immunofluorescence studies, Boyden-chamber assay, wound healing assay and air-liquid interface (ALI) culture were used to assess different cellular and molecular changes associated with EMT. The results depict that CSE increased the cytotoxicity along with a concurrent increase in the expression and activity of MMP-2 and -9. CSE further altered EMT markers like E-cadherin, N-cadherin, vimentin, and the molecular modulators of EMT such as β-catenin and pGSK-3β. Further, CSE also upregulated EGFR, AKT, and ERK1/2 in airway epithelial cells. SB-3CT, a known inhibitor of MMP-2 and -9, altered and reversed the expression of markers of EMT and kinases, validating the role of MMP-2 and -9 in CSE-induced EMT. Fisetin, a plant-derived bioflavonoid, also reversed the expression of EMT markers and molecular regulators in a similar fashion as SB-3CT. In summary, this study highlights the role of MMP-2 and -9 in CSE-induced EMT and curate its molecular cascade through EGFR/AKT/ERK/β-catenin axis, which could be restored by MMP-2 and -9 inhibitor and fisetin. Fisetin is hitherto unknown to modulate CSE-induced MMPs activity in airway epithelial cells, and our study suggests its potential role as a therapeutic approach in CSE-induced EMT in lung epithelial cells.

Abstract
Background Hepatocellular carcinoma (HCC) is the most common type of primary liver cancer with high incidence. The underlying molecular mechanisms of HCC development have been intensively studied. CLK3 (CDC Like Kinase 3) is a nuclear dual-specificity kinase and regulates gene splicing. We investigated the expression profile and functional role of CLK3 in HCC. Methods Immunohistochemistry (IHC) and Western blot were performed to determine CLK3 expression in HCC tissues. Bioinformatics analysis using TCGA and GEO database was conducted to evaluate the relationship between CLK3 expression and HCC prognosis. Cell proliferation was assessed by CCK8, EdU and colony formation assays, while transwell and wound-healing assays were performed to investigate the cell migration and invasion in vitro. Xenograft nude mouse model was used to test the function of CLK3 on tumor growth in vivo. Luciferase reporter assay, Western blot and RT-qPCR were conducted to verify the miRNA that directly targeted CLK3. Results CLK3 was markedly upregulated in HCC tissues, and the expression levels of CLK3 were closely associated with TNM stages and HCC prognosis. Functional analysis indicated that knockdown of CLK3 could suppress HCC cell growth, invasion and migration in vitro, and inhibit tumor development in vivo. Moreover, CLK3 was demonstrated as a direct target of miR-144 and miR-144 expression was inversely correlated with CLK3 expression in HCC. Enforced overexpression of miR-144 markedly inhibited the CLK3 expression while overexpression of CLK3 partially reversed the inhibitory function of miR-144 on HCC cell growth and metastasis. Mechanistically, we found that miR-144 overexpression inhibited Wnt/β-catenin signaling and the inhibition could be partly abolished by overexpression of CLK3. Conclusion In summary, we demonstrate tumor suppressor miR-144 suppresses hepatocellular carcinoma development and metastasis via regulating CLK3 and Wnt/β-catenin signaling, indicating that miR-144/CLK3 could be used for HCC diagnosis and treatment.

Abstract
Human endometrium undergoes cycles of proliferation and differentiation throughout the reproductive years of women. The endometrial stem/progenitor cells contribute to this regenerative process. They lie in the basalis layer of the endometrium next to the myometrium. We hypothesized that human myometrial cells provide niche signals regulating the activities of endometrial mesenchymal stem-like cells (eMSCs). In vitro coculture of myometrial cells enhanced the colony-forming and self-renewal ability of eMSCs. The cocultured eMSCs retained their multipotent characteristic and exhibited a greater total cell output when compared with medium alone culture. The expression of active β-catenin in eMSCs increased significantly after coculture with myometrial cells, suggesting activation of WNT/β-catenin signaling. Secretory factors in spent medium from myometrial cell culture produced the same stimulatory effects on eMSCs. The involvement of WNT/β-catenin signaling in self-renewal of eMSCs was confirmed with the use of WNT activator (Wnt3A conditioned medium) and WNT inhibitors (XAV939 and inhibitor of Wnt Production-2 [IWP-2]). The myometrial cells expressed more WNT5A than other WNT ligands. Recombinant WNT5A stimulated whereas anti-WNT5A antibody suppressed the colony formation, self-renewal, and T-cell factor/lymphoid enhancer-binding factor (TCF/LEF) transcriptional activities of eMSCs. Moreover, eMSCs expressed FZD4 and LRP5. WNT5A is known to activate the canonical WNT signaling in the presence of these receptor components. WNT antagonist, DKK1, binds to LRP5/6. Consistently, DKK1 treatment nullified the stimulatory effect of myometrial cell coculture. In conclusion, our findings show that the myometrial cells are niche components of eMSCs, modulating the self-renewal activity of eMSCs by WNT5A-dependent activation of WNT/β-catenin signaling.

Abstract
The class Frizzled (FZD) or class F of G protein-coupled receptors consists of 10 FZD paralogues and Smoothened (SMO). FZDs coordinate wingless/Int-1 signaling and SMO mediates Hedgehog signaling. Class F receptor signaling is intrinsically important for embryonic development and its dysregulation leads to diseases, including diverse forms of tumors. With regard to the importance of class F signaling in human disease, these receptors provide an attractive target for therapeutics, exemplified by the use of SMO antagonists for the treatment of basal cell carcinoma. Here, we review recent structural insights in combination with a more detailed functional understanding of class F receptor activation, G protein coupling, conformation-based functional selectivity, and mechanistic details of activating cancer mutations, which will lay the basis for further development of class F-targeting small molecules for human therapy. SIGNIFICANCE STATEMENT: Stimulated by recent insights into the activation mechanisms of class F receptors from structural and functional analysis of Frizzled and Smoothened, we aim to summarize what we know about the molecular details of ligand binding, agonist-driven conformational changes, and class F receptor activation. A better understanding of receptor activation mechanisms will allow us to engage in structure- and mechanism-driven drug discovery with the potential to develop more isoform-selective and potentially pathway-selective drugs for human therapy.

Abstract
Emetine, an amoebicidal drug, exerts potent anticancer activity against various solid tumors, however, the underlying molecular mechanism remains unclear. In the present study, the effects of emetine were investigated on various proteins involved in the Wnt/β‑catenin signaling pathway, which has been linked to various human cancers. It was revealed that emetine blocked Wnt/β‑catenin signaling by targeting components of this pathway, including the low‑density lipoprotein‑receptor‑related protein 6 (LRP6) and disheveled (DVL). Moreover, nanomolar concentrations of emetine decreased phosphorylation of these proteins and suppressed the expression of Wnt target genes, including fibronectin, frizzled‑7 (Fzd7), c‑Myc, Nanog and CD133 in MDA‑MB‑231 and MDA‑MB‑468 breast cancer cells. Additionally, emetine treatment induced apoptosis and suppressed the viability, migration, invasion, and sphere formation of breast cancer cells. Collectively the present results indicated that emetine antagonizes Wnt/β‑catenin signaling, providing insight into the molecular mechanism underlying the anticancer activity of emetine.

Abstract
The skin functions as a barrier between the organism and the surrounding environment. Direct exposure to external stimuli and the accumulation of genetic mutations may lead to abnormal cell growth, irreversible tissue damage and potentially favor skin malignancy. Skin homeostasis is coordinated by an intricate signaling network, and its dysregulation has been implicated in the development of skin cancers. Wnt signaling is one such regulatory pathway orchestrating skin development, homeostasis, and stem cell activation. Aberrant regulation of Wnt signaling cascades not only gives rise to tumor initiation, progression and invasion, but also maintains cancer stem cells which contribute to tumor recurrence. In this review, we summarize recent studies highlighting functional evidence of Wnt-related oncology in keratinocyte carcinomas, as well as discussing preclinical and clinical approaches that target oncogenic Wnt signaling to treat cancers. Our review provides valuable insight into the significance of Wnt signaling for future interventions against keratinocyte carcinomas.

Abstract
Antitumor drug resistance remains a major challenge in cancer chemotherapy. Here we investigated the mechanism of acquired resistance to a novel anticancer agent RH1 designed to be activated in cancer cells by the NQO1 enzyme. Data show that in some cancer cells RH1 may act in an NQO1-independent way. Differential proteomic analysis of breast cancer cells with acquired resistance to RH1 revealed changes in cell energy, amino acid metabolism and G2/M cell cycle transition regulation. Analysis of phosphoproteomics and protein kinase activity by multiplexed kinase inhibitor beads showed an increase in the activity of protein kinases involved in the cell cycle and stemness regulation and downregulation of proapoptotic kinases such as JNK in RH1-resistant cells. Suppression of JNK leads to the increase of cancer cell resistance to RH1. Moreover, resistant cells have enhanced expression of stem cell factor (SCF) and stem cell markers. Inhibition of SCF receptor c-KIT resulted in the attenuation of cancer stem cell enrichment and decreased amounts of tumor-initiating cells. RH1-resistant cells also acquire resistance to conventional therapeutics while remaining susceptible to c-KIT-targeted therapy. Data show that RH1 can be useful to treat cancers in the NQO1-independent way, and targeting of the cancer stem cells might be an effective approach for combating resistance to RH1 therapy.

Long noncoding RNA LINC01089 predicts clinical prognosis and inhibits cell proliferation and invasion through the Wnt/β-catenin signaling pathway in breast cancer. Onco Targets Ther 2019; 12:4883-4895. [PMID: 31417284 PMCID: PMC6593691 DOI: 10.2147/ott.s208830] [Citation(s) in RCA: 32] [Impact Index Per Article: 6.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/15/2019] [Accepted: 05/24/2019] [Indexed: 12/27/2022] Open
Abstract
Background Recently, emerging evidence has indicated crucial roles for long noncoding RNAs (lncRNAs) in breast cancer (BC) development and progression. Our study aimed to investigate the clinical significance of LINC01089 in patients with BC and to determine its biological functions and underlying molecular mechanisms. Materials and methods Correlations between LINC01089 expression and the clinicopathological characteristics of BC patients were assessed using chi-square tests. The Kaplan-Meier method was used to produce survival curves. The clinical risk characteristics associated with the overall survival and recurrence-free survival of patients with BC were estimated using univariate and multivariate Cox regression analyses. Several methods were used to determine the expression profile, biological functions and underlying mechanisms of LINC01089 in BC, including cell proliferation assays, colony formation assays, flow cytometry, transwell assays, wound healing assays, quantitative real-time polymerase chain reaction and Western blotting. Results LINC01089 was downregulated in BC tissues and cell lines. Low LINC01089 expression was significantly correlated with age (P=0.026), lymph node metastasis (P=0.003), and poor prognosis of patients with BC. According to the multivariate Cox regression analysis results, LINC01089 was an independent prognostic indicator of overall survival (P=0.032) and recurrence-free survival (P=0.014). Functional studies revealed significant decreases in the proliferation, migration, and invasion of tumor cells overexpressing LINC01089, and EGF could reverse above effects of LINC01089 on BC cells. Additionally, increased LINC01089 expression promoted apoptosis and cell cycle arrest at G0/G1 phase, accompanied by decreased expression of the key cell cycle regulators CDK4 and CDK6. Loss-of-function assays confirmed partial results. Mechanistically, LINC01089 blocked the Wnt/β-catenin pathway and the expression of downstream target genes by inhibiting β-catenin expression at the transcriptional level. Conclusion Based on our results, LINC01089 functions as a tumor suppressor and potentially represents a novel prognostic indicator and therapeutic target in BC. ![]()

Abstract
Background Normal epithelial cells rapidly undergo apoptosis as soon as they lose contact with the extracellular matrix (ECM), which is termed as anoikis. However, cancer cells tend to develop a resistance mechanism to anoikis. This acquired ability is termed as anoikis resistance. Cancer cells, with anoikis resistance, can spread to distant tissues or organs via the peripheral circulatory system and cause cancer metastasis. Thus, inhibition of anoikis resistance blocks the metastatic ability of cancer cells. Methods Anoikis-resistant CAL27 (CAL27AR) cells were induced from CAL27 cells using the suspension culture approach. Transcriptome analysis was performed using RNA-Seq to study the differentially expressed genes (DEGs) between the CAL27ARcells and the parental CAL27 cells. Gene function annotation and Gene Ontology (GO) enrichment analysis were performed using DAVID database. Signaling pathways involved in DEGs were analyzed using Gene Set Enrichment Analysis (GSEA) software. Analysis results were confirmed by reverse transcription PCR (RT-PCR), western blotting, and gene correlation analysis based on the TCGA database. Results GO enrichment analysis indicated that the biological process (BP) of the DEGs was associated with epidermal development, DNA replication, and G1/S transition of the mitotic cell cycle. The analysis of cellular component (CC) showed that the most significant up-regulated genes were related to extracellular exosome. KEGG Pathway analysis revealed that 23 signaling pathways were activated (p-value ≤ 0.05, FDR q-value ≤ 0.05) and 22 signaling pathways were suppressed (p-value ≤ 0.05, FDR q-value ≤ 0.05). The results from the GSEA indicated that in contrast to the inhibition of EGFR signaling pathway, the VEGF signaling pathway was activated. The VEGF signaling pathway possibly activates STAT3 though induction of STAT3 phosphorylation. Gene correlation analysis revealed that the VEGFA- STAT3-KLF4-CDKN1A signal axis was not only present in head and neck squamous carcinoma (HNSCC) but also two other epithelial-derived carcinomas that highly express VEGFA, including kidney renal clear cell carcinoma (KIRC) and ovarian serous cystadenocarcinoma (OV).

Abstract
Hepatocellular carcinoma (HCC) is one of the most prevalent and deadly malignancies characterized by high rate of recurrence. Tumor recurrence is often attributed to the presence of a subpopulation of cells with stem cell properties, referred to as cancer stem cells (CSCs). Traditionally, cancer therapies target the entire bulk of tumor cells; however, they are poorly effective against CSCs, characterized by higher drug resistance. Therefore, approaches targeting CSCs may be required in addition to conventional chemotherapy to prevent tumor recurrence. In this study, we investigated an approach to target HCC by combining the conventional chemotherapeutic drug, cisplatin, to target the bulk of tumor cells, and differentiation therapy by delivering the gene encoding HNF4α, an important regulator of hepatocyte differentiation, to target CSCs. We used the Huh7 cell line as an in vitro model of HCC, which is characterized by a high proportion of CD133-expressing CSCs. By using flow cytometry, we separated CD133+ and CD133- Huh7 cell subpopulations and have shown that the former has highly pronounced in vivo tumorigenic capacity in contrast to the latter, which could not generate tumors in vivo. For the dual delivery of HNF4α-encoding plasmid and cisplatin, we used polyethyleneimine-modified mesoporous silica nanoparticles (PMSNs) as the nanocarriers. Here, we show that the treatment of CD133-expressing Huh7 cells with HNF4α-loaded PMSNs can suppress their proliferation rate, decrease the proportion of CSCs, downregulate stemness-associated genes, and increase the expression of mature hepatocyte-associated genes. At the same time, the treatment of Huh7 with PMSNs loaded with both HNF4α-encoding plasmid and cisplatin could block them in the S-phase of the cell cycle and cause apoptosis. In addition, dually loaded PMSNs were the most efficient formulation in suppressing tumor growth in vivo. To summarize, in this study, we tested the nanoparticle-based delivery system as both chemotherapy and gene-based therapy agents, which has great potential for development of effective treatment of HCC.

Abstract
Cancer stem cells pose significant obstacles to curative treatment contributing to tumor relapse and poor prognosis. They share many signaling pathways with normal stem cells that control cell proliferation, self-renewal, and cell fate determination. One of these pathways known as Wnt is frequently implicated in carcinogenesis where Wnt hyperactivation is seen in cancer stem cells. Yet, the role of conserved genomic alterations in Wnt genes driving tumor progression across multiple cancer types remains to be elucidated. In an integrated pan-cancer study involving 21 cancers and 18,484 patients, we identified a core Wnt signature of 16 genes that showed a high frequency of somatic amplifications linked to increased transcript expression. The signature successfully predicted overall survival rates in 6 cancer cohorts (n = 3050): bladder (P = 0.011), colon (P = 0.013), head and neck (P = 0.026), pan-kidney (P < 0.0001), clear cell renal cell (P < 0.0001), and stomach (P = 0.032). Receiver operating characteristic analyses revealed that the performance of the 16-Wnt-gene signature was superior to tumor staging benchmarks in all 6 cohorts and multivariate Cox regression analyses confirmed that the signature was an independent predictor of overall survival. In bladder and renal cancer, high-risk patients as predicted by the Wnt signature had more hypoxic tumors and a combined model uniting tumor hypoxia and Wnt hyperactivation resulted in further increased death risks. Patients with hyperactive Wnt signaling had molecular features associated with stemness and epithelial-to-mesenchymal transition. Our study confirmed that genomic amplification underpinning pan-cancer Wnt hyperactivation and transcriptional changes associated with molecular footprints of cancer stem cells lead to increased death risks.

Abstract
The miR-17-92 cluster is involved in animal development and homeostasis, and its dysregulation leads to human diseases such as cancer. In the present study, we investigated the functional link between miR-17-92 cluster and Wnt/β-catenin signaling pathway in ICP2 and DF1 cells. We demonstrated that ectopic expression of either LEF1 or β-catenin increased the promoter activity of the miR-17-92 cluster host gene (MIR17HG) and combined ectopic expression of LEF1 and β-catenin further enhanced the promoter activity; while knockdown of either LEF1 or β-catenin reduced the MIR17HG promoter activity. Both LEF1 and β-catenin could directly bind to the MIR17HG promoter. Furthermore, we demonstrated that low doses of lithium chloride (LiCl), an activator of Wnt/β-catenin signaling pathway, increased MIR17HG promoter activity and the endogenous expression of the miR-17-92 cluster, while high doses of LiCl had the opposite effects. Treatment with XAV-939, an inactivator of the Wnt/β-catenin pathway, reduced the endogenous expression of miR-17-92 cluster. Finally, we found that low doses of LiCl promoted the proliferation of ICP2 and DF1 cells, while high doses of LiCl inhibited the proliferation of ICP2 and DF1 cells. Taken together, our results reveal that MIR17HG is a target of LEF1 and the Wnt/β-catenin pathway and suggest that the miR-17-92 cluster may, at least in part, mediate the proliferation-promoting effect of the Wnt/β-catenin pathway in cell proliferation.

Abstract
ETHNOPHARMACOLOGICAL RELEVANCE Korean Red ginseng extract (RG) is one of the most widely used traditional health functional food in Asia, which invigorates immunity and vital energy. RG have been suggested to inhibit proliferation, invasion, and inflammation in several cancer cell lines. Correspondingly, clinical studies have raised the possibility that RG could augment therapeutic efficacy in cancer patients. However, little is known about the anti-cancer effects of RG in glioblastoma (GBM), the most common and aggressive brain tumor for which effective therapeutic regimens need to be developed. AIM OF THIS STUDY Here, we assessed the in vivo and in vitro anti-cancer properties of RG in a patient-derived xenograft mouse model and GBM stem cell (GSC) line. MATERIALS AND METHODS We evaluated the anti-cancer effects of RG in patient-derived GBM xenograft mice with and without combined concurrent chemo- and radiation therapy (CCRT). Furthermore, we verified the in vitro effects of RG on the proliferation, cell death, and stem cell-like self-renewal capacity of cancer cells. Finally, we investigated the signaling pathway affected by RG, via which its anti-cancer effects were mediated. RESULTS When combined with CCRT, RG impeded GBM progression by reducing cancer cell proliferation and ionized calcium-binding adapter molecule 1 (IBA1)-positive immune cell recruitment. The anti-cancer effects of RG were mediated by Rg3 and Rh2 ginsenosides. Rg3 promoted cell death while Rh2 did not. Furthermore, both Rg3 and Rh2 reduced cell viability and self-renewal capacity of GSCs by inhibiting Wnt/β-catenin signaling. CONCLUSION Therefore, our observations imply that RG could be applied to the GBM patients in parallel with CCRT to enhance therapeutic efficacy.

Abstract
The history of drug development clearly shows the scale of painstaking effort leading to a finished product - a highly biologically active agent that would be at the same time no or little toxic to human organism. Moreover, the aim of modern drug discovery can move from "one-molecule one-target" concept to more promising "one-molecule multiple-targets" one, particularly in the context of effective fight against cancer and other complex diseases. Gratifyingly, natural compounds are excellent source of potential drug leads. One of such promising naturally-occurring drug candidates is a polyether ionophore - salinomycin (SAL). This compound should be identified as multi-target agent for two reasons. Firstly, SAL combines a broad spectrum of bioactivity, including antibacterial, antifungal, antiviral, antiparasitic and anticancer activity, with high selectivity of action, proving its significant therapeutic potential. Secondly, the multimodal mechanism of action of SAL has been shown to be related to its interactions with multiple molecular targets and signalling pathways that are synergistic for achieving a therapeutic anticancer effect. On the other hand, according to the Paul Ehrlich's "magic bullet" concept, invariably inspiring the scientists working on design of novel target-selective molecules, a very interesting direction of research is rational chemical modification of SAL. Importantly, many of SAL derivatives have been found to be more promising as chemotherapeutics than the native structure. This concise review article is focused both on the possible role of SAL and its selected analogues in future antimicrobial and/or cancer therapy, and on the potential use of SAL as a new class of multiple-targeted "magic bullet" because of its multimodal mechanism of action.

Abstract
Although integrin α9 (ITGA9) is known to be involved in cell adhesion and motility, its expression in cancer and its role in tumor growth and metastasis remain largely unknown. Our study was designed to investigate the role of ITGA9 in triple-negative breast cancer (TNBC). ITGA9 expression in TNBC cells was knocked out (KO) using CRISPR/Cas9 technology. Four orthotopic mouse mammary xenograft tumor models coupled with cell culture studies were performed to determine the effect of ITGA9 depletion on TNBC tumor growth and metastasis and the underlying mechanism. Bioinformatics analysis showed that ITGA9 level is significantly higher in TNBC than other breast cancer subtypes, and higher ITGA9 level is associated with significantly worse distant metastasis-free survival and recurrence-free survival in TNBC patients. Experimentally, ITGA9 KO significantly reduced TNBC cell cancer stem cell (CSC)-like property, tumor angiogenesis, tumor growth and metastasis by promoting β-catenin degradation. Further mechanistic studies revealed that ITGA9 KO causes integrin-linked kinase (ILK) relocation from the membrane region to the cytoplasm, where it interacts with protein kinase A (PKA) and inhibits PKA activity leading to increased activity of glycogen synthase kinase 3 (GSK3) and subsequent β-catenin degradation. Overexpressing β-catenin in ITGA9 KO cells reversed the inhibitory effect of ITGA9 KO on tumor growth and metastasis. Furthermore, ITGA9 downregulation in TNBC tumors by nanoparticle-mediated delivery of ITGA9 siRNA drastically decreased tumor angiogenesis, tumor growth and metastasis. These findings indicate that ITGA9 depletion suppresses TNBC tumor growth and metastasis by promoting β-catenin degradation through the ILK/PKA/GSK3 pathway.
