Abstract
Lack of appropriate tools for visualizing cell membrane molecules at the nanoscale in a non-invasive and label-free fashion limits our understanding of many vital cellular processes. Here, we use tip-enhanced Raman spectroscopy (TERS) to visualize the molecular distribution in pancreatic cancer cell (BxPC-3) membranes in ambient conditions without labelling, with a spatial resolution down to ca. 2.5 nm. TERS imaging reveals segregation of phenylalanine-, histidine-, phosphatidylcholine-, protein-, and cholesterol-rich BxPC-3 cell membrane domains at the nm length-scale. TERS imaging also showed a cell membrane region where cholesterol is mixed with protein. Interestingly, the higher resolution TERS imaging revealed that the molecular domains observed on the BxPC-3 cell membrane are not chemically "pure" but also contain other biomolecules. These results demonstrate the potential of TERS for non-destructive and label-free imaging of cell membranes with nanoscale resolution.

Association between Immunohistochemistry Markers and Tumor Features and Their Diagnostic and Prognostic Values in Intrahepatic Cholangiocarcinoma. COMPUTATIONAL AND MATHEMATICAL METHODS IN MEDICINE 2022; 2022:8367395. [PMID: 35529254 PMCID: PMC9071873 DOI: 10.1155/2022/8367395] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 01/30/2022] [Revised: 02/14/2022] [Accepted: 02/22/2022] [Indexed: 12/28/2022]
Abstract
This study investigated the expression of some frequently used immunohistochemistry (IHC) markers. Besides, we evaluated their correlations with the clinical features and outcomes of intrahepatic cholangiocarcinoma (ICC). Patients who underwent surgical removal of the ICC tumors were followed up for 4 years. The paraffin-embedded sections were used to obtain different markers, including CK7, CK19, CK20, CDX2, Glypican3, Hepa1, Ki-67, Villin, and SATB1. Overall survival in relation to IHC marker expression patterns and other clinical characteristics was evaluated by Kaplan-Meier survival curve and log-rank test, followed by the Cox proportional hazard model (to evaluate the relationship between multiple factors and the overall postoperative survival). A total of 122 ICC patients (67 males and 55 females, averagely aged 57.75) were included in this study. There were 44 cases with vascular invasion, 46 cases with lymphatic metastasis, and 13 cases with distant metastasis. CK7 was negatively correlated with lymphatic metastasis; and in distant-metastasis cases, the positive ratio of SATB1 was lower. Interestingly, SATB1 expression indicated a poorer survival, while Villin expression was associated with a better survival. The COX regression analysis showed that female was a protective factor versus male, Villin expression was a strong protective factor, and Ki-67 expression was correlated with a poor survival. Together, IHC markers are associated with tumor features and postoperative survival, especially for SATB1 as a risk factor and Villin as a protective marker, and female ICC patients may have better survival than males.

Endoplasmic reticulum stress: Multiple regulatory roles in hepatocellular carcinoma. Biomed Pharmacother 2021; 142:112005.

Abstract
BACKGROUND Endoplasmic reticulum (ER) stress is a basic cellular stress response that maintains cellular protein homeostasis under endogenous or exogenous stimuli, which depends on the stimulus, its intensity, and action time. The ER produces a corresponding cascade reaction for crosstalk of adaptive and/or pro-death regulation with other organelles. Hepatocellular carcinoma(HCC) is one of the most common malignant solid tumors with an extremely poor prognosis. Viral hepatitis infection, cirrhosis, and steatohepatitis are closely related to the occurrence and development of HCC, and ER stress has gradually been shown to be a major mechanism. Moreover, an increasing need for protein and lipid products and relative deficiencies of oxygen and nutrients for rapid proliferation and endoplasmic reticulum stress are undoubtedly involved. Therefore, to fully and comprehensively understand the regulatory role of endoplasmic reticulum stress in the occurrence and progression of HCC is of vital importance to explore its pathogenesis and develop novel anti-cancer strategies. METHODOLOGY We searched for relevant publications in the PubMed databases using the keywords "Endoplasmic reticulum stress", "hepatocellular carcinoma" in last five years,and present an overview of the current knowledge that links ER stress and HCC, which includes carcinogenesis, progression, and anti-cancer strategies, and propose directions of future research. RESULT ER stress were confirmed to be multiple regulators or effectors of cancer, which also be confirmed to drive tumorigenesis and progression of HCC. Targeting ER stress signaling pathway and related molecules could play a critical role for anti-HCC and has become a research hotspot for anti-cancer in recent years. CONCLUSION ER stress are critical for the processes of the tumorigenesis and progression of tumors. For HCC, ER stress was associated with tumorigenesis, development, metastasis, angiogenesis and drug resistance, targeting ER stress has emerged as a potential anti-tumor strategy.

Abstract
Histidine-rich calcium binding protein (HRC) is markedly overexpressed in hepatocellular carcinoma (HCC) and is significantly correlated with metastasis. Anoikis resistance and endoplasmic reticulum (ER) stress may have a critical effect on survival before metastasis. However, the potential functions of HRC in anoikis resistance in HCC remain unknown. Here, we uncovered the clinical value of HRC and its functional significance on anoikis in HCC. The positive expression of HRC was observably correlated with tumor size, tumor encapsulation, and tumor-node-metastasis (TNM) stage. The expression of HRC increased in HCC cells cultured in suspension. HRC enhanced the anoikis resistance of HCC, and promoted the HCC metastasis in vivo. Mechanistically, the anoikis resistance was probably dependent on endoplasmic reticulum stress. Modulating HRC level changed the ERS to affect anoikis resistance by acting protein kinase RNA-like ER kinase (PERK)-eIF2a-ATF4-CHOP signaling axis. In conclusion, we define HRC as a novel candidate oncogene involved in anoikis resistance and HCC metastasis, and provide a new potential therapeutic target for HCC.

Abstract
Simple Summary Liver cancer (hepatocellular carcinoma) is a significant health burden worldwide. It is often not detected until at an advanced stage when there are few treatment options available. Changes in calcium concentrations within liver cancer cells are essential for regulating their growth, death, and migration (metastasis). Our aim was to review published papers which have identified proteins involved in calcium signaling as potential drug targets for the treatment of liver cancer. About twenty calcium signaling proteins were identified, including those involved in regulating calcium concentrations in the cytoplasm, endoplasmic reticulum and mitochondria. A few of these have turned out to be sites of action of natural products previously known to inhibit liver cancer. More systematic studies are now needed to determine which calcium signaling proteins might be used clinically for treatment of liver cancer, especially advanced stage cancers and those resistant to inhibition by current drugs. Abstract Hepatocellular carcinoma (HCC) is a considerable health burden worldwide and a major contributor to cancer-related deaths. HCC is often not noticed until at an advanced stage where treatment options are limited and current systemic drugs can usually only prolong survival for a short time. Understanding the biology and pathology of HCC is a challenge, due to the cellular and anatomic complexities of the liver. While not yet fully understood, liver cancer stem cells play a central role in the initiation and progression of HCC and in resistance to drugs. There are approximately twenty Ca2+-signaling proteins identified as potential targets for therapeutic treatment at different stages of HCC. These potential targets include inhibition of the self-renewal properties of liver cancer stem cells; HCC initiation and promotion by hepatitis B and C and non-alcoholic fatty liver disease (principally involving reduction of reactive oxygen species); and cell proliferation, tumor growth, migration and metastasis. A few of these Ca2+-signaling pathways have been identified as targets for natural products previously known to reduce HCC. Promising Ca2+-signaling targets include voltage-operated Ca2+ channel proteins (liver cancer stem cells), inositol trisphosphate receptors, store-operated Ca2+ entry, TRP channels, sarco/endoplasmic reticulum (Ca2++Mg2+) ATP-ase and Ca2+/calmodulin-dependent protein kinases. However, none of these Ca2+-signaling targets has been seriously studied any further than laboratory research experiments. The future application of more systematic studies, including genomics, gene expression (RNA-seq), and improved knowledge of the fundamental biology and pathology of HCC will likely reveal new Ca2+-signaling protein targets and consolidate priorities for those already identified.

Abstract
Male Breast Cancer (MBC) is a rare and aggressive disease that is associated with genetic factors. Mutations in BRCA1 and BRCA2 account for 10% of all MBC cases suggesting that other genetic factors are involved. The aim of the present study is to screen whole BRCA1 and BRCA2 exons using the Ampliseq BRCA panel in Tunisian MBC patients with family history. Furthermore, we performed exome sequencing using the TruSight One sequencing panel on an early onset BRCA negative patient. We showed that among the 6 MBC patients, only one (MBC-F1) harbored a novel frameshift mutation in exon 2 of the BRCA2 gene (c.17-20delAAGA, p.Lys6Xfs) resulting in a short BRCA2 protein of only 6 amino-acids. We selected 9 rare variants after applying several filter steps on the exome sequencing data. Among these variants, and based on their role in breast carcinogenesis, we retained 6 candidate genes (MSH5, DCC, ERBB3, NOTCH3, DIAPH1, and DNAH11). Further studies are needed to confirm the association of the selected genes with family MBC.

Abstract
Introduction Intrinsic vitamin D affects the proliferation, apoptosis, invasion, metastasis, and tumorigenesis of lung cancer by regulating tumor signaling pathways. Histidine-rich calcium-binding protein (HRC) maintains Ca2+ homeostasis, which plays crucial roles in the occurrence and development of cancer. Objectives Our study aims to investigate the ability of vitamin D in the regulation of HRC and the role of HRC playing in lung cancer. Methods We investigated the effects of vitamin D on lung cancer and the underlying mechanisms, by measuring HRC and vitamin D receptor (VDR) expression in lung cancer, paracancer, and normal tissues from patients using immunohistochemistry, western blotting, and real time RT-PCR. We transfected H460 lung cancer cells (supplemented or not with vitamin D) with PX458-HRC and pcDNA3.1-HRC plasmids and injected mice with lung cancer cells harboring pcDNA3.1-vector or pcDNA3.1-HRC plasmids. Results Vitamin D inhibited HRC expression and H460 cell migration and proliferation, and promoted apoptosis compared with controls. The expression of HRC and VDR was significantly upregulated and downregulated, respectively, in lung cancer versus paracancer or normal tissues. Cell proliferation and migration were reduced, apoptotic cells were more and tumors were smaller in mice treated with vitamin D/cholecalciferol cholesterol emulsion (CCE) than in vitamin D/CCE+HRC+/+ mice. Conclusion Vitamin D inhibited lung cancer tumor growth, migration, and proliferation by downregulating HRC.

Abstract
Long noncoding RNAs (lncRNAs) have been confirmed, which are involved in tumorigenesis and metastasis in colorectal cancer (CRC). FOXC2 antisense RNA 1 (FOXC2-AS1) was reported, facilitating the proliferation and progression in several cancers. However, the role of FOXC2-AS1 in CRC cell migration and metastasis is not unclear. In this study, we observed that lncRNA FOXC2-AS1 was upregulated in CRC tissues, and its high expression indicated the poor survival in CRC patients. Meanwhile, FOXC2-AS1 was higher in CRC tissues with metastasis than that of nonmetastatic tumor tissues. We found that FOXC2-AS1 was predominately expressed in the nucleus of tissues and cells. FOXC2-AS1 knockdown suppressed CRC cell growth, invasion, and metastasis in vitro and in vivo. Moreover, FOXC2-AS1 could positively regulate the neighboring gene FOXC2 and stabilized FOXC2 mRNA by forming a RNA duplex. Meanwhile, ectopic expression of FOXC2 could obviously alleviate the suppressed effects caused by silencing FOXC2-AS1. For the mechanism, FOXC2-AS1 knockdown could reduce intracellular Ca2+ levels, inhibited FA formation and FAK signaling, and these suppressed effects were mitigated by increasing FOXC2 expression. These results demonstrated that FOXC2-AS1 enhances FOXC2 mRNA stability to promote CRC proliferation, migration, and invasion by activation of Ca2+-FAK signaling, which implicates that FOXC2-AS1 may represent a latent effective therapeutic target for CRC progression.

Abstract
Accumulating evidence indicates that KIAA1199 plays a vital role in tumor progression. However, the role of KIAA1199 in hepatocellular carcinoma (HCC) still remains unknown. In this study, we found that KIAA1199 was upregulated in human HCC tissues and in highly metastatic HCC cell lines. Furthermore, the expression of KIAA1199 was significantly correlated with tumor size and metastasis in HCC. Knockdown of KIAA1199 inhibited cell proliferation and migration in vitro, and suppressed tumorigenicity and lung metastasis in vivo. In addition, silencing of KIAA1199 induced G1 phase arrest by reducing cyclinD1 expression. Moreover, KIAA1199 knockdown induced apoptosis by activating endoplasmic reticulum (ER) stress, which was based on the upregulation of ER stress markers, activating transcription factor 4 (ATF4) and CAAT/enhancer-binding protein homologous protein (CHOP). In conclusion, our data demonstrated that KIAA1199 knockdown inhibited the growth and metastasis of HCC.

Abstract
Microrchidia 2 (MORC2) is important in DNA damage repair and lipogenesis, however, the clinical and functional role of MORC2 in liver cancer remains to be fully elucidated. The aim the present study was to clarify the role of MORC2 in liver cancer. Expression profile analysis, immunohistochemical staining, reverse transcription-quantitative polymerase chain reaction analysis and western blot analysis were performed to evaluate the levels of MORC2 in liver cancer patient specimens and cell lines; subsequently the expression of MORC2 was suppressed or increased in liver cancer cells and the effects of MORC2 on the cancerous transformation of liver cancer cells were examined in vitro and in vivo. MORC2 was upregulated in liver cancer tissues, and the upregulation was associated with certain clinicopathologic features of patients with liver cancer. MORC2 knockdown caused marked inhibition of liver cancer cell proliferation and clonogenicity, whereas the overexpression of MORC2 substantially promoted liver cancer cell proliferation. In addition, the knockdown of MORC2 inhibited the migratory and invasive ability of liver cancer cells, whereas increased migration and invasion rates were observed in cells with ectopic expression of MORC2. In a model of nude mice, the overexpression of MORC2 promoted tumorigenicity and markedly enhanced pulmonary metastasis of liver cancer. Furthermore, MORC2 regulated apoptosis and its expression level had an effect on the sensitivity of liver cancer cells to doxorubicin, 5-fluorouracil and cisplatin. Mechanically, MORC2 modulated the mitochondrial apoptotic pathway, possibly in a p53-dependent manner, and its dysregulation also resulted in the abnormal activation of the Hippo pathway. For the first time, to the best of our knowledge, the present study confirmed that MORC2 was a novel oncogene in liver cancer. These results provide useful insight into the mechanism underlying the tumorigenesis and progression of liver cancer, and offers clues into potential novel liver cancer therapies.

Abstract
Alternative polyadenylation (APA), a post-transcriptional modification, has been implicated in many diseases, but especially in tumor proliferation. CFIm25, the 25 kDa subunit of human cleavage factor Im (CFIm), is a key factor in APA. We show that CFIm25 expression is reduced in human hepatocellular carcinoma (HCC), and its expression correlates with metastasis. Kaplan-Meier analysis indicated that CFIm25 is related to overall survival in HCC. Moreover, CFIm25 expression is negatively related to the metastatic potential of HCC cell lines. CFIm25 knockdown promotes cell invasion and migration in vitro, while overexpression of CFIm25 inhibits cell invasion and migration in vitro and inhibits intrahepatic and lung metastasis in vivo. Additional studies showed that CFIm25 disrupts epithelial-mesenchymal transition by increasing E-cadherin, that it inhibits HCC cell migration and invasion by blocking the p38 and JNK/c-Jun signaling pathways, and that CFIm25 knockdown increases the transcriptional activity of activating protein-1 (AP-1). These findings indicate that therapy directed at increasing CFIm25 expression is a potential HCC treatment.

LncSHRG promotes hepatocellular carcinoma progression by activating HES6. Oncotarget 2017; 8:70630-70641.

Abstract
Hepatocellular carcinoma, one of the most common cancers, leads to mass mortality worldwide currently. However, the underlying mechanism of its oncogenesis remains to be elucidated. Here we identified that a long noncoding RNA, lncSHRG, was greatly upregulated in human hepatocellular carcinoma samples. We found that lncSHRG was essential for liver cancer cell proliferation and tumor propagation in mice. In mechanism, lncSHRG recruits SATB1 to bind to HES6 promoter and initiates HES6 expression. HES6, which is highly expressed in hepatocellular carcinoma, promotes tumor cell proliferation. High expression level of HES6 is positively correlated with clinical severity and poor prognosis of people with hepatocellular carcinoma. Altogether, our research provides a new insight on the mechanism of hepatocellular carcinoma progression.

Abstract
OBJECTIVE Our aim is to evaluate the expression of SATB1 in human oral squamous cell carcinomas (OSCC) and its role in the invasiveness and metastasis of OSCC. SUBJECTS AND METHODS A human OSCC tissue microarray was used to evaluate the expression pattern of SATB1. SATB1 mRNA knockdown was performed in human OSCC cell lines SCC25 and Cal27 to assess the function of SATB1 in the invasiveness and metastasis of OSCC. RESULTS SATB1 is highly expressed in human OSCC determined by immunohistochemistry, and its nuclear/cytoplasmic ratio of histoscore is significantly correlated with patients' prognosis. Reduced cell motility, invasiveness, expression of epithelial to mesenchymal transition (EMT) markers (N-cadherin and β-catenin), and elevated expression of epithelial markers were observed in SATB1-knockdown cells in in vitro studies. Depletion of SATB1 also restored a cobblestone-like morphology in TGF-β1-treated cells. CONCLUSIONS These findings suggest SATB1 may play an important role in OSCC invasiveness and metastasis.

Hepatic SATB1 induces paracrine activation of hepatic stellate cells and is upregulated by HBx. Sci Rep 2016; 6:37717.

Abstract
Chronic hepatitis B virus (HBV) infection is a major cause of chronic liver diseases, but its involvement in hepatic fibrogenesis remains unclear. Special AT-rich binding protein 1 (SATB1) has been implicated in reprogramming chromatin organization and transcription profiles in many cancers and non-cancer-related conditions. We found that hepatic SATB1 expression was significantly up-regulated in fibrotic tissues from chronic hepatitis B virus (HBV)-infected patients and HBV transgenic (HBV-Tg) mouse model. Knockdown of SATB1 in the liver significantly alleviated CCl4-induced fibrosis in HBV-Tg mouse model. Moreover, we suggested HBV encoded x protein (HBx) induced SATB1 expression through activation of JNK and ERK pathways. Enforced expression of SATB1 in hepatocytes promoted the activation and proliferation of hepatic stellate cells (HSCs) by secretion of connective tissue growth factor (CTGF), Interleukin-6 (IL-6) and platelet derived growth factor-A (PDGF-AA). Our findings demonstrated that HBx upregulated hepatic SATB1 which exerted pro-fibrotic effects by paracrine activation of stellate cells in HBV-related fibrosis.

Abstract
We have recently shown that the histidine-rich calcium binding protein (HRC) promotes the invasion and metastasis of hepatocellular carcinoma (HCC). In the current study, we evaluated whether HRC may also affect the growth of HCC. We found that ectopic expression of HRC obviously enhanced proliferation and colony formation, while suppression of HRC exhibited inhibitory effects. Furthermore, we demonstrated that HRC promoted tumor growth in nude mice. These effects may result from the ability of HRC to upregulate cyclinD1 and cyclin-dependent kinase 2 (CDK2) expressions and promote G1/S transition. Further study showed that MEK/ERK signaling pathway was involved in HRC-induced cell proliferation. Interestingly, overexpression or depletion of HRC revealed its regulation on endoplasmic reticulum stress (ERS) and apoptosis, which was partially dependent on PERK/ATF4/CHOP signaling pathway. In addition, blocking ERS using 4-phenylbutyric acid (4-PBA) not only downregulated the expression of PERK, ATF4 and CHOP, but also significantly decreased apoptosis induced by HRC silence, whereas ERS inducer thapsigargin (TG) exerted the opposite effects. Our study thus demonstrates a role of HRC in promoting HCC growth, besides its role in inducing HCC metastasis, and highlights HRC as a promising intervention target for HCC.

Up-regulation of SPOCK1 induces epithelial-mesenchymal transition and promotes migration and invasion in esophageal squamous cell carcinoma. J Mol Histol 2015; 46:347-56.

Abstract
Invasion and metastasis are the major causes of death in patients with esophageal squamous cell carcinoma (ESCC). Recent studies have confirmed that SPARC/osteonectin, cwcv and kazal-like domains proteoglycan 1 (SPOCK1) plays multiple roles in cancer progression. This study aims to explore the clinical characteristics of SPOCK1 in ESCC and its roles in the migration and invasion of ESCC cell lines. In this study, the up-regulation of SPOCK1 expression was frequently detected in primary ESCC tumor tissues compared with those in non-tumor tissues, which was significantly associated with tumor invasion (p = 0.004) and distant metastasis (p = 0.010). SPOCK1 was expressed at higher level in TE13 cells as compared to the low malignant Eca109 and TE1 cells. Overexpression of SPOCK1 in Eca109 cells decreased the expressions of epithelial marker E-cadherin and ZO-1, while increased mesenchymal marker Vimentin and N-cadherin levels. After ectopic expression of SPOCK1, Eca109 cells exhibited a morphological change from an epithelial cobblestone phenotype to an elongated fibroblastic phenotype, concomitant with cytoskeletal rearrangements and increased migration and invasion, suggesting that EMT occurs. While silencing SPOCK1 in TE13 cells had the opposite effects. These results suggest that up-regulation of SPOCK1 in ESCC induces EMT, thus promotes migration and invasion in ESCC cells.
