Abstract
Zinc transporter ZIP9 is also a membrane androgen receptor that mediates androgen-dependent zinc and G-protein signaling to modulate tumorigenic responses in cancer cells. It is unclear whether unliganded ZIP9 causes similar responses. ZIP9 overexpression in MDA-MB-231 breast cancer cells (ZIP9 cells) increased zinc levels and cell migration/invasion which was mimicked with a zinc ionophore and attenuated with a zinc chelator, suggesting these tumorigenic responses are zinc-dependent. Expression of migration markers MYL9 and CYR61 was elevated in ZIP9 cells and further increased together with cell migration by forskolin treatment and blocked with H-89, indicating they are mediated through an AC/PKA pathway. Knockdown of ZIP9 expression in MDA-MB-468 cells decreased cell migration/invasion, migration markers and zinc levels, confirming similar roles of unliganded ZIP9 in another breast cancer cell line. Testosterone treatment further increased migration, biomarker expression and zinc in ZIP9 cells, suggesting it may act through similar pathways to induce tumorigenic responses.

Potential Therapies Targeting the Metabolic Reprogramming of Diabetes-Associated Breast Cancer. J Pers Med 2023; 13:jpm13010157. [PMID: 36675817 PMCID: PMC9861470 DOI: 10.3390/jpm13010157] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Revised: 01/08/2023] [Accepted: 01/10/2023] [Indexed: 01/18/2023] Open
Abstract
In recent years, diabetes-associated breast cancer has become a significant clinical challenge. Diabetes is not only a risk factor for breast cancer but also worsens its prognosis. Patients with diabetes usually show hyperglycemia and hyperinsulinemia, which are accompanied by different glucose, protein, and lipid metabolism disorders. Metabolic abnormalities observed in diabetes can induce the occurrence and development of breast cancer. The changes in substrate availability and hormone environment not only create a favorable metabolic environment for tumorigenesis but also induce metabolic reprogramming events required for breast cancer cell transformation. Metabolic reprogramming is the basis for the development, swift proliferation, and survival of cancer cells. Metabolism must also be reprogrammed to support the energy requirements of the biosynthetic processes in cancer cells. In addition, metabolic reprogramming is essential to enable cancer cells to overcome apoptosis signals and promote invasion and metastasis. This review aims to describe the major metabolic changes in diabetes and outline how cancer cells can use cellular metabolic changes to drive abnormal growth and proliferation. We will specifically examine the mechanism of metabolic reprogramming by which diabetes may promote the development of breast cancer, focusing on the role of glucose metabolism, amino acid metabolism, and lipid metabolism in this process and potential therapeutic targets. Although diabetes-associated breast cancer has always been a common health problem, research focused on finding treatments suitable for the specific needs of patients with concurrent conditions is still limited. Most studies are still currently in the pre-clinical stage and mainly focus on reprogramming the glucose metabolism. More research targeting the amino acid and lipid metabolism is needed.

Abstract
BACKGROUND We investigated the level of Cysteine-rich 61 (CYR61) in premature ovarian failure as well as its regulatory molecular mechanism in this study. METHODS AND RESULTS Cyclophosphamide (CTX) was used to induce OGCs (rat ovarian granulosa cells) and rats to establish in vivo and in vitro premature ovarian failure models. H&E staining was used to detect the pathological changes of ovarian histopathology. Si-NLRP3 (NOD-like receptor thermal protein domain associated protein 3, NLRP3) and si-CYR61 were transfected into OGCs using lipofectamine 3000. RT-qPCR and western blot were used to detect the expressions of CYR61 in ovarian tissue and OGCs. It showed that the expression of CYR61 was significantly down-regulated in premature ovarian failure model. Cell viability was detected using a Cell Counting Kit-8 (CCK-8) kit. TUNEL (Terminal deoxynucleotidyl transferase-mediated dUTP biotin nick end labeling) staining was used to detect the apoptosis. 5-Ethynyl-2'-deoxyuridine (EdU) and SA-β-gal (senescence-associated β-galactosidase) staining were used to assess the proliferation and senescence. The expression of CYR61 in OGCs and ovarian tissues were detected by immunofluorescence and immunohistochemical staining. Overexpression of CYR61 significantly promoted OGCs proliferation and inhibited pyroptosis and apoptosis. Western blot was used to detect the protein expressions of p53 and p21 in OGCs. Flow cytometry was used to detect the pyroptosis. CYR61 overexpression inhibited the expression of NLRP3 and caspase-1 in CTX-induced OGCs according to western blot results. Moreover, we found that CYR61 overexpression down-regulated the protein expressions of p53 and p21 in CTX-induced OGCs. CONCLUSION CYR61 inhibited CTX-induced OGCs senescence, and the mechanism may be related to the regulation of caspase-1/NLRP3-induced pyroptosis.

Abstract
Purpose: To investigate the role of serum CYR61 as a biomarker for the diagnosis of breast cancer and to analyze the association between serum CYR61 levels and the clinicopathological features in breast cancer patients. Methods: Serum CYR61 was measured in breast cancer patients and healthy controls by ELISA. Results: The serum levels of CYR61 in breast cancer patients were higher than those in healthy controls. The area under the receiver operating characteristic curve for CYR61 was higher than that for carcinoembryonic antigen and carbohydrate antigen 15-3. The increased CYR61 levels were correlated with menopausal status and Ki67 expression. Conclusion: Serum CYR61 might be a novel biomarker to assist the diagnosis and clinicopathological status assessment of breast cancer.

Abstract
BACKGROUND This study aimed to investigate the association of calorie and carbohydrate intake with tumour grade in early detection of breast cancer (BC) in Iranian women. MATERIALS AND METHODS This case-control study carried out on 62 women with high grade BC and 93 women with low grade BC. Information about confounding variables was collected through a questionnaire. Dietary intake of calorie and macronutrients was assessed by a valid 122-item semi-quantitative food frequency questionnaire. RESULTS Individuals with high grade BC had significantly lower calorie (0.16, 0.04-0.61) and higher carbohydrate intake (4.02; 1.28-12.63) compared with those with low grade BC after controlling for age. This correlation remained significant after adjusting for confounding factors. CONCLUSION Our results showed that lower intakes of calorie and higher carbohydrate are directly related to the high grade of tumour at the early detection of people with BC after modifying a wide range of confounding factors.

Matrix-bound Cyr61/CCN1 is required to retain the properties of the bone marrow mesenchymal stem cell niche but is depleted with aging. Matrix Biol 2022; 111:108-132. [PMID: 35752272 PMCID: PMC10069241 DOI: 10.1016/j.matbio.2022.06.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/06/2021] [Revised: 05/30/2022] [Accepted: 06/22/2022] [Indexed: 11/17/2022]
Abstract
Previously, we showed that extracellular matrices (ECMs), produced ex vivo by various types of stromal cells, direct bone marrow mesenchymal stem cells (BM-MSCs) in a tissue-specific manner and recapitulate physiologic changes characteristic of the aging microenvironment. In particular, BM-MSCs obtained from elderly donors and cultured on ECM produced by young BM stromal cells showed improved quantity, quality and osteogenic differentiation. In the present study, we searched for matrix components that are required for a functional BM-MSC niche by comparing ECMs produced by BM stromal cells from "young" (≤25 y/o) versus "elderly" (≥60 y/o) donors. With increasing donor age, ECM fibrillar organization and mechanical integrity deteriorated, along with the ability to promote BM-MSC proliferation and responsiveness to growth factors. Proteomic analyses revealed that the matricellular protein, Cyr61/CCN1, was present in young, but undetectable in elderly, BM-ECM. To assess the role of Cyr61 in the BM-MSC niche, we used genetic methods to down-regulate the incorporation of Cyr61 during production of young ECM and up-regulate its incorporation in elderly ECM. The results showed that Cyr61-depleted young ECM lost the ability to promote BM-MSC proliferation and growth factor responsiveness. However, up-regulating the incorporation of Cyr61 during synthesis of elderly ECM restored its ability to support BM-MSC responsiveness to osteogenic factors such as BMP-2 and IGF-1. We next examined aging bone and compared bone mineral density and Cyr61 content of L4-L5 vertebral bodies in "young" (9-11 m/o) and "elderly" (21-33 m/o) mice. Our analyses showed that low bone mineral density was associated with decreased amounts of Cyr61 in osseous tissue of elderly versus young mice. Our results strongly demonstrate a novel role for ECM-bound Cyr61 in the BM-MSC niche, where it is responsible for retention of BM-MSC proliferation and growth factor responsiveness, while depletion of Cyr61 from the BM niche contributes to an aging-related dysregulation of BM-MSCs. Our results also suggest new potential therapeutic targets for treating age-related bone loss by restoring specific ECM components to the stem cell niche.

Abstract
Uterine fibroids (UF) are the most common benign gynecologic tumors and lead to heavy menstrual bleeding, severe anemia, abdominal pain, and infertility, which seriously harm a women’s health. Unfortunately, the regulatory mechanisms of UF have not been elucidated. Recent studies have demonstrated that miRNAs play a vital role in the development of uterine fibroids. As a high-throughput technology, microarray is utilized to identify differentially expressed genes (DEGs) and miRNAs (DEMs) between UF and myometrium. We identified 373 candidate DEGs and the top 100 DEMs. Function enrichment analysis showed that candidate DEGs were mainly enriched in biological adhesion, locomotion and cell migration, and collagen-containing extracellular matrix. Subsequently, protein-protein interaction (PPI) networks are constructed to analyze the functional interaction between DEGs and screen hub DEGs. Subsequently, the expression levels of hub DEGs were validated by real-time PCR of clinical UF samples. The DGIdb database was used to select candidate drugs for hub DEGs. Molecular docking was applied to test the affinity between proteins and drugs. Furthermore, target genes for 100 candidate DEMs were predicted by miRwalk3.0. After overlapping with 373 candidate DEGs, 28 differentially expressed target genes (DEGTs) were obtained. A miRNA-mRNA network was constructed to investigate the interactions between miRNA and mRNA. Additionally, two miRNAs (hsa-miR-381-3p and hsa-miR-181b-5p) were identified as hub DEMs and validated through RT-PCR. In order to better elucidate the pathogenesis of UF and the synergistic effect between miRNA and transcription factor (TF), we constructed a miRNA-TF-mRNA regulatory network. Meanwhile, in vitro results suggested that dysregulated hub DEMs were associated with the proliferation, migration, and apoptosis of UF cells. Our findings provided a novel horizon to reveal the internal mechanism and novel targets for the diagnosis and treatment of UF.

Abstract
Triple-negative breast cancer (TNBC) represents a subset of breast cancer characterized by high aggressiveness and poor prognosis. Currently, there is no curative therapeutic regimen for TNBC patients. In this study, molecular hybridization strategy is adopted by combining benzopyran and indole pharmacophores together, and a library of structurally simple 1,3,4,9-tetrahydropyrano[3,4-b]indoles was rapidly constructed. The structure-activity relationship studies indicated that compound 23 exhibited the most potent effect against the MDA-MB-231 cells with IC50 value of 2.29 μM. Mechanistic studies revealed that compound 23 inhibited cell proliferation via arresting cell cycle at G0/G1 phase. It induced cell apoptosis by disruption of mitochondrial membrane potential (MMP), accumulation of reactive oxygen species (ROS), reduction of glutathione (GSH), elevation of intracellular calcium ion (Ca2+) and activation of caspase cascade. Furthermore, compound 23 significantly inhibited the regulators of PI3K/AKT/mTOR pathway in MDA-MB-231 cells, suggesting that PI3K/AKT/mTOR pathway was involved in the 23-mediated apoptosis. To our knowledge, this is the first example of the anti-cancer activity study of indole-fused pyrans through suppressing PI3K/AKT/mTOR pathway. Overall, the current study suggested that compound 23 would serve as a promising lead compound for TNBC treatment.

Abstract
Background Testicular germ cell tumours (TGCTs) have a high metastasis rate. However, the mechanisms related to their invasion, progression and metastasis are unclear. Therefore, we investigated gene expression changes that might be linked to metastasis in seminomatous testicular germ cell tumour (STGCT) patients. Methods Defined areas [invasive tumour front (TF) and tumour centre (TC)] of non-metastatic (with surveillance and recurrence-free follow-up >2 years) and metastatic STGCTs were collected separately using laser capture microdissection. The expression of 760 genes related to tumour progression and metastasis was analysed using nCounter technology and validated with quantitative real-time PCR and enzyme-linked immunosorbent assay. Results Distinct gene expression patterns were observed in metastatic and non-metastatic seminomas with respect to both the TF and TC. Comprehensive pathway analysis showed enrichment of genes related to tumour functions such as inflammation, angiogenesis and metabolism at the TF compared to the TC. Remarkably, prominent inflammatory and cancer-related pathways, such as interleukin-6 (IL-6) signalling, integrin signalling and nuclear factor-κB signalling, were significantly upregulated in the TF of metastatic vs non-metastatic tumours. Conclusions IL-6 signalling was the most significantly upregulated pathway in metastatic vs non-metastatic tumours and therefore could constitute a therapeutic target for future personalised therapy. In addition, this is the first study showing intra- and inter-tumour heterogeneity in STGCT.

Abstract
The insulin-like growth factor (IGF) system is a dynamic network of proteins, which includes cognate ligands, membrane receptors, ligand binding proteins and functional downstream effectors. It plays a critical role in regulating several important physiological processes including cell growth, metabolism and differentiation. Importantly, alterations in expression levels or activation of components of the IGF network are implicated in many pathological conditions including diabetes, obesity and cancer initiation and progression. In this review we will initially cover some general aspects of IGF action and regulation in cancer and then focus in particular on the role of transcriptional regulators and novel interacting proteins, which functionally contribute in fine tuning IGF1R signaling in several cancer models. A deeper understanding of the biological relevance of this network of IGF1R modulators might provide novel therapeutic opportunities to block this system in neoplasia.

However, the function of IGF1 in PTC progression remains unclear. Methods Seventy‐three pairs of PTC tissue specimens and adjacent normal specimens form and normal cell line and PTC cell lines were collected in this study. The immunohistochemistry (IHC) assay was performed to test the expression of IGF1. The RNA isolation and quantitative real‐time PCR assays (qRT‐PCR assays) and Western blot analysis were used to test mRNA and protein expression. Cell proliferation assay, EdU assay, flow cytometry assay, wound healing assay, and Transwell invasion assay were performed to test cell proliferation, invasion, and apoptosis. Results We found that the expression of IGF1 in PTC tissue samples was higher than that in adjacent normal specimens and was significantly associated with tumor size, TNM staging, and lymph node metastasis. Furthermore, IGF1 treatment significantly increased cell viability in a dose‐dependent manner. EdU assay also demonstrated the effect of IGF1 on the proliferation of BCPAP and TPC1 cells. Moreover, IGF1 treatment effectively increased the invasive capacity of BCPAP and TPC1 cells. More importantly, IGF1 treatment could significantly enhance the phosphorylation of STAT3 in BCPAP and TPC1 cells. Moreover, cryptotanshinone (Cryp) treatment reversed the effect of IGF1 treatment on cell viability and invasion of BCPAP and TPC1 cells. Conclusion Collectively, IGF1 promotes proliferation and invasion of PTC progression through the STAT3 signaling pathway.

[PMID: 32124532 DOI: 10.1002/pbc.28221] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 01/29/2020] [Accepted: 01/30/2020] [Indexed: 12/29/2022]
Abstract
BACKGROUND Hepatoblastoma (HB) is the most common pediatric liver malignancy, occurring mainly during the first 4 years of life. Recent studies unraveled the frequent, coordinated activation of Wnt/β-catenin and YAP/Hippo (where YAP is yes-associated protein) pathways in human HB samples. Furthermore, it was found that concomitant overexpression of activated forms of β-catenin and YAP in the mouse liver triggers HB formation in YAP/β-catenin mice. Cyclin-dependent kinases 9 (CDK9) is an elongating kinase, which has been shown to mediate YAP-driven tumorigenesis. The role of CDK9 in HB molecular pathogenesis has not been investigated to date. METHODS CDK9 expression was determined in human HB lesions, HB cell lines, and YAP/β-catenin mouse livers. CDK9 was silenced in human HB cell lines and the effects on growth rate and YAP targets were analyzed. Hydrodynamic transfection of YAPS127A and ∆N90-β-catenin together with either shCdk9 or control shLuc (where Luc is luciferase) plasmids was employed to assess the requirement of Cdk9 for HB development in vivo. RESULTS Nuclear immunoreactivity for CDK9 protein was more pronounced in human HB samples and YAP/β-catenin mouse HB tumor tissues than in corresponding surrounding nontumorous liver tissues. CDK9 protein was also expressed in human HB cell lines. Silencing of CDK9 in human HB cell lines did not lead to consistent effects on HB cell growth or YAP target gene expression. Surprisingly, silencing of Cdk9 led to accelerated liver tumorigenesis in YAP/β-catenin mice. CONCLUSION CDK9 is not a major downstream mediator of YAP oncogenic function in HB development and progression.

Abstract
OBJECTIVES The aim of this multicenter study was to investigate the prognostic role of type 2 diabetes mellitus (T2DM) comorbidity in a large multi-institutional cohort of patients with primary T1HG/G3 non-muscle-invasive bladder cancer (NMIBC) treated with transurethral resection of the bladder (TURB). MATERIALS AND METHODS A total of 1,172 patients with primary T1 HG/G3 who had NMIBC on re-TURB and who received adjuvant intravesical bacillus Calmette-Guérin therapy with maintenance were included. Endpoints were recurrence-free survival and progression-free survival. RESULTS A total of 231 (19.7%) of patients had T2DM prior to TURB. Five-year recurrence-free survival estimates were 12.5% in patients with T2DM compared to 36% in patients without T2DM, P < 0.0001. Five-year PFS estimates were 60.5% in patients with T2DM compared to 70.2% in patients without T2DM, P = 0.003. T2DM was independently associated with disease recurrence (hazard ratio = 1.41; 95% confidence interval = 1.20-1.66, P < 0.001) and progression (hazard ratio = 1.27; 95% confidence interval = 0.99-1.63, P < 0.001), after adjusting for other known predictive factors such as tumor size, multifocality, T1G3 on re-TURB, body mass index, lymphovascular invasion, and neutrophil-to-lymphocytes ratio. CONCLUSIONS Given the potential implications for management, prospective validation of this finding along with translational studies designed to investigate the underlying biology of such an association are warranted.

Abstract
Metastasis is the main cause of cancer related deaths, and unfolding the molecular mechanisms underlying metastatic progression is critical for the development of novel therapeutic approaches. Notch is one of the key signaling pathways involved in breast tumorigenesis and metastasis. Notch activation induces pro-metastatic processes such as migration, invasion and epithelial to mesenchymal transition (EMT). However, molecular mediators working downstream of Notch in these processes are not fully elucidated. CYR61 is a secreted protein implicated in metastasis, and its inhibition by a monoclonal antibody suppresses metastasis in xenograft breast tumors, indicating the clinical importance of CYR61 targeting. Here, we aimed to investigate whether CYR61 works downstream of Notch in inducing pro-metastatic phenotypes in breast cells. We showed that CYR61 expression is positively regulated by Notch activity in breast cells. Notch1-induced migration, invasion and anchorage independent growth of a normal breast cell line, MCF10A, were abrogated by CYR61 silencing. Furthermore, upregulation of core EMT markers upon Notch1-activation was impaired in the absence of CYR61. However, reduced migration and invasion of highly metastatic cell line, MDA MB 231, cells upon Notch inhibition was not dependent on CYR61 downregulation. In conclusion, we showed that in normal breast cell line MCF10A, CYR61 is a mediator of Notch1-induced pro-metastatic phenotypes partly via induction of EMT. Our results imply CYR61 as a prominent therapeutic candidate for a subpopulation of breast tumors with high Notch activity.

Abstract
Non-thermal atmospheric pressure plasma has been widely used for preclinical studies in areas such as wound healing, blood coagulation, and cancer therapy. We previously developed plasma-activated medium (PAM) and plasma-activated Ringer's lactate solutions (PAL) for cancer treatments. Many in vitro and in vivo experiments demonstrated that both PAM and PAL exhibit anti-tumor effects in several types of cancer cells such as ovarian, gastric, and pancreatic cancer cells as well as glioblastoma cells. However, interestingly, PAM induces more intracellular reactive oxygen species in glioblastoma cells than PAL. To investigate the differences in intracellular molecular mechanisms of the effects of PAM and PAL in glioblastoma cells, we measured gene expression levels of antioxidant genes such as CAT, SOD2, and GPX1. Microarray and quantitative real-time PCR analyses revealed that PAM elevated stress-inducible genes that induce apoptosis such as GADD45α signaling molecules. PAL suppressed genes downstream of the survival and proliferation signaling network such as YAP/TEAD signaling molecules. These data reveal that PAM and PAL induce apoptosis in glioblastoma cells by different intracellular molecular mechanisms.

Abstract
BACKGROUND Smoking is a strong risk factor for the development of Graves' ophthalmopathy (GO). Immediate early genes (IEGs) are overexpressed in patients with active GO compared to healthy controls. The aim of this study was to study the effects of tobacco smoking and simvastatin on preadipocytes and orbital fibroblasts (OFs) in the adipogenic process. METHODS Cigarette smoke extract (CSE) was generated by a validated pump system. Mouse 3T3-L1 preadipocytes or OFs were exposed to 10% CSE with or without simvastatin. Gene expression was studied in preadipocytes and OFs exposed to CSE with or without simvastatin and compared to unexposed cells or cells treated with a differentiation cocktail. RESULTS In 3T3-L1 preadipocytes, Cyr61, Ptgs2, Egr1 and Zfp36 expression levels were two-fold higher in cells exposed to CSE than in unexposed cells. Simvastatin downregulated the expression of these genes (1.6-fold, 5.5-fold, 3.3-fold, 1.4-fold, respectively). CSE alone could not stimulate preadipocytes to differentiate. Scd1, Ppar-γ and adipogenesis were downregulated in simvastatin-treated preadipocytes compared to nontreated preadipocytes 18-, 35- and 1.7-fold, respectively. In OFs, similar effects of CSE were seen on the expression of CYR61 (1.4-fold) and PTGS2 (3-fold). Simvastatin downregulated adipogenesis, PPAR-γ (2-fold) and SCD (27-fold) expression in OFs. CONCLUSION CSE upregulated early adipogenic genes in both mouse 3T3-L1 preadipocytes and human OFs but did not by itself induce adipogenesis. Simvastatin inhibited the expression of both early and late adipogenic genes and adipogenesis in preadipocytes and human OFs. The effect of simvastatin should be investigated in a clinical trial of patients with GO.

Abstract
Extramedullary infiltration (EMI) is common in patients with acute myeloid leukemia (AML) and is closely associated with the prognosis of disease. We previously reported that patients carrying the AML1/ETO (A/E) fusion gene and expressing the amyloid precursor protein (APP) tended to develop EMI, and had a poor prognosis. In the present study, the relapse-free survival (RFS) time and overall survival (OS) time were significantly lower in patients with EMI. The results demonstrated that the EMI incidence was significantly higher (P<0.05), while the RFS and OS rates were significantly lower (P<0.05), in patients with high APP expression. Kasumi-1 cells, which are A/E+, and the APP gene were used as the in vitro cell model to detect the mechanism of action in detail. Following the knockdown of APP expression, cell migration was significantly reduced (P<0.05). Furthermore, western blotting demonstrated that the protein expression of phosphorylated extracellular-signal-regulated kinase (p-ERK), matrix metalloproteinase-2 (MMP-2) and c-Myc was markedly reduced following interference of APP, while the expression of CXCR4 and MMP-9 was not altered. Kasumi-1 cells were co-cultured with p-ERK or c-Myc inhibitors and demonstrated that the APP/p-ERK/c-Myc/MMP-2 pathway was involved in signal transduction and regulation of cell migration. MicroRNA-144 (miR-144) mimics and transfected Kasumi-1 cells were generated. Reverse transcription-quantitative polymerase chain reaction and western blotting demonstrated that miR-144 was a negative regulator of APP. Taken together, the findings of the present study suggest that miR-144 negatively targets the APP gene and regulates cell migration via the APP/p-ERK/c-Myc/MMP-2 pathway.

Abstract
Asthma is characterized by inflammation and remodeling of the airways. Insulin‑like growth factor-1 (IGF‑1) serves an important role in the repair of lung tissue injury and airway remodeling by elevating collagen and elastin content, increasing the thickness of smooth muscle and promoting the proliferation of lung epithelial and interstitial cells, as well as fibroblasts; however, the content of IGF‑1 and its cellular origin in the lungs of patients with asthma remain unknown. In the present study, a mouse model of asthma was constructed. Following isolation of alveolar macrophages (AMs), the content of IGF‑1 in lung tissue and bronchoalveolar lavage fluid (BALF) was detected by ELISA. The proliferation and phagocytosis of alveolar epithelial cells (AECs) stimulated by IGF‑1 were detected by Cell Counting Kit‑8 method and flow cytometry, respectively. In the present study, IGF‑1 was upregulated in the lung tissues of asthmatic mice, and the content of IGF‑1 in BALF was also elevated. Depletion of AMs by treating mice with 2‑chloroadenosine via nose dripping reversed the increase of IGF‑1 by 80% in lung tissues and by ~100% in BALF of asthmatic mice, suggesting that elevated IGF‑1 in asthmatic mice predominantly originated from AMs. As IGF‑1 promotes the proliferation and phagocytosis of AECs, AM‑derived IGF‑1 may serve an important role in the regulation of airway inflammation and remodeling in asthmatic mice.

Abstract
Obese women diagnosed with breast cancer have an increased risk for metastasis, and the underlying mechanisms are not well established. Within the mammary gland, adipose-derived stromal cells (ASCs) are heterogeneous cells with the capacity to differentiate into multiple mesenchymal lineages. To study the effects of obesity on ASCs, mice were fed a control diet (CD) or high-fat diet (HFD) to induce obesity, and ASCs were isolated from the mammary glands of lean and obese mice. We observed that obesity increased ASCs proliferation, decreased differentiation potential, and upregulated expression of α-smooth muscle actin, a marker of activated fibroblasts, compared to ASCs from lean mice. To determine how ASCs from obese mice impacted tumor growth, we mixed ASCs isolated from CD- or HFD-fed mice with mammary tumor cells and injected them into the mammary glands of lean mice. Tumor cells mixed with ASCs from obese mice grew significantly larger tumors and had increased invasion into surrounding adipose tissue than tumor cells mixed with control ASCs. ASCs from obese mice demonstrated enhanced tumor cell invasion in culture, a phenotype associated with increased expression of insulin-like growth factor-1 (IGF-1) and abrogated by IGF-1 neutralizing antibodies. Weight loss induced in obese mice significantly decreased expression of IGF-1 from ASCs and reduced the ability of the ASCs to induce an invasive phenotype. Together, these results suggest that obesity enhances local invasion of breast cancer cells through increased expression of IGF-1 by mammary ASCs, and weight loss may reverse this tumor-promoting phenotype.

Insulin-like growth factor type I selectively binds to G-quadruplex structures. Biochim Biophys Acta Gen Subj 2018; 1863:31-38. [PMID: 30278241 DOI: 10.1016/j.bbagen.2018.09.022] [Citation(s) in RCA: 12] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2018] [Revised: 09/26/2018] [Accepted: 09/27/2018] [Indexed: 11/20/2022]
Abstract
BACKGROUND G-quadruplex has been viewed as a promising therapeutic target in oncology due to its potentially important roles in physiological and pathological processes. Emerging evidence suggests that the biological functions of G-quadruplexes are closely related to the binding of some proteins. Insulin-like growth factor type I (IGF-1), as a significant modulator of cell growth and development, may serve as a quadruplex-binding protein. METHODS The binding affinity and selectivity of IGF-1 to different DNA motifs in solution were measured by using fluorescence spectroscopy, Surface Plasmon Resonance (SPR), and force-induced remnant magnetization (FIRM). The effects of IGF-1 on the formation and stability of G-quadruplex structures were evaluated by circular dichroism (CD) and melting fluorescence resonance energy transfer (FRET) spectroscopy. The influence of quadruplex-specific ligands on the binding of G-quadruplexes with IGF-1 was determined by FIRM. RESULTS IGF-1 shows a binding specificity for G-quadruplex structures, especially the G-quadruplex structure with a parallel topology. The quadruplex-specific ligands TMPyP4 and PDS (Pyridostatin) can inhibit the interaction between G-quadruplexes and proteins. CONCLUSIONS IGF-1 is demonstrated to selectively bind with G-quadruplex structures. The use of quadruplex-interactive ligands could modulate the binding of IGF-1 to G-quadruplexes. GENERAL SIGNIFICANCE This study provides us with a new perspective to understand the possible physiological relationship between IGF-1 and G-quadruplexes and also conveys a strategy to regulate the interaction between G-quadruplex DNA and proteins.

Inositol-C2-PAF acts as a biological response modifier and antagonizes cancer-relevant processes in mammary carcinoma cells. Cell Oncol (Dordr) 2018; 41:505-516.

Abstract
PURPOSE Previous studies have identified alkyl-phospholipids as promising compounds for cancer therapy by targeting constituents of the cell membrane and different signaling pathways. We previously showed that the alkylphospholipid Inositol-C2-PAF inhibits the proliferation and migration of immortalized keratinocytes and the squamous carcinoma-derived cell line SCC-25. Here, we investigated the effect of this compound on growth and motility as well as its mode of action in mammary carcinoma-derived cell lines. METHODS Using BrdU incorporation and haptotactic cell migration assays, we assessed the effects of Inositol-C2-PAF on MCF-7 and MBA-MB-231 cell proliferation and migration. The phosphorylation status of signaling molecules was investigated by Western blotting as well as indirect immunofluorescence analysis and capillary isoelectric focusing. RESULTS We found that Inositol-C2-PAF inhibited the growth as well as the migration in MCF-7 and MBA-MB-231 cells. Furthermore, we found that this compound inhibited phosphorylation of the protein kinase Akt at serine residue 473, but had no impact on phosphorylation at threonine 308. Phosphorylation of other kinases, such as Erk1/2, FAK and Src, which are targeted by Inositol-C2-PAF in other cells, remained unaffected by the compound in the mammary carcinoma-derived cell lines tested. In MCF-7 cells, we found that IGF-1-induced growth, as well as phosphorylation of AktS473, mTOR and the tumor suppressor pRB, was inhibited in the presence of Inositol-C2-PAF. Moreover, we found that in these cells IGF-1 had no impact on migration and did not seem to be linked to full Akt activity. Therefore, MCF-7 cell migration appears to be inhibited by Ino-C2-PAF in an Akt-independent manner. CONCLUSION The antagonistic effects of Inositol-C2-PAF on cell migration and proliferation are indicative for its potential for breast cancer therapy, alone or in combination with other cytostatic drugs.

Strong enhancement by IGF1-R antagonists of hepatocellular carcinoma cell migration inhibition by Sorafenib and/or vitamin K1. Cell Oncol (Dordr) 2018; 41:283-296.

Abstract
PURPOSE Emerging evidence indicates that combining Sorafenib with vitamin K1 (VK1) may result in a synergistic inhibition of hepatocellular carcinoma (HCC) cell migration and proliferation. Despite this synergy, its benefits may be limited due to drug resistance resulting from cross-talk with the tumor microenvironment. Insulin-like growth factor-1 (IGF1) signaling acts as an important modulator of HCC cell growth, motility and drug resistance. Therefore, we aimed to explore the effects of Sorafenib in combination with VK1 and/or IGF1-R antagonists on HCC cells. METHODS Scratch wound migration assays were performed to assess the motility of HCC-derived PLC/PRF/5, HLF and Hep3B cells. The synergistic, additive or antagonistic effects of Sorafenib, VK1 and IGF1-R antagonists on HCC cell motility were assessed using CompuSyn software. The effects mediated by these various compounds on HCC cytoskeleton organization were evaluated using DyLight 554 Phalloidin staining. Proliferation and migration-associated signaling pathways were analyzed in PLC/PRF/5 cells using Erk1/2 and Akt activation kits and Western blotting (Mek, JNK, Akt, Paxillin and p38), respectively. RESULTS The effects of the IGF1-R antagonists GSK1838705A and OSI-906 on HCC cell migration inhibition after Sorafenib and/or VK1 administration, individually or in combination, were evaluated. We found a synergistic effect in PLC/PRF/5, HLF and Hep3B cells for combinations of fixed doses of GSK1838705A or OSI-906 together with different doses of Sorafenib and/or VK1. The levels of synergy were found to be stronger at higher Sorafenib and/or VK1 concentrations and lower or absent at lower concentrations, with some variation among the different cell lines tested. In addition, we found that in PLC/PRF/5 and HLF cells IGF1-R blockage strongly enhanced the reduction and redistribution of F-actin induced by Sorafenib and/or VK1 through alterations in the phosphorylation levels of some of the principal proteins involved in the MAPK signaling cascade, which is essential for cell migration. CONCLUSIONS Our results indicate that modulation of the efficacy of Sorafenib through combinations with VK1 and/or IGF1-R antagonists results in synergistic inhibition of HCC cell migration.

Cyr61 and YB-1 are novel interacting partners of uPAR and elevate the malignancy of triple-negative breast cancer. Oncotarget 2018; 7:44062-44075.

Abstract
The triple-negative breast cancer (TNBC) is a very aggressive tumor type often occurring in young women and is associated with a bad prognosis for the patients. TNBC lacks established targets for breast cancer therapy, such as the estrogen receptor (ER), progesterone receptor (PR) and the human epidermal growth factor receptor 2 (HER2). Therefore, novel therapeutic targets and strategies are needed for an improved treatment of this breast cancer subtype. TNBC and respective cell lines often overexpress proteins of the urokinase plasminogen activator system (uPAS) including uPA, its receptor uPAR and inhibitor PAI-1, which together with co-factors contribute to the malignancy of TNBC. Here, two novel interacting partners of uPAR, the cysteine-rich angiogenic inducer 61 (Cyr61) and the Y-box-binding protein 1 (YB-1) were identified and their differential expression demonstrated in TNBC cells as well as in tumors. In the TNBC cohort, both interactors significantly correlated with expression levels of cathepsin B, c-Met and the tumor grade. In addition, expression levels of Cyr61 significantly correlated with cathepsin D (p=0.03), insulin receptor (p≤0.001), insulin-like growth factor receptor 1 (IGF1R, p=0.015) and also with YB-1 (p=0.0004) levels. The interactions of uPAR with Cyr61 significantly correlated with expression levels of tumor-promoting biomarkers including plasminogen (p=0.0014), cathepsin B (p=0.032), c-Met (p=0.0192) as well as with the tumor grade (p=0.02). In multivariate survival analysis, YB-1 showed independent prognostic value (p=0.01). As the novel interacting partners, also together with uPAR, contribute to tumor progression and metastasis, both may be potential therapeutic targets in breast cancer.

Abstract
Cysteine-rich angiogenic inducer 61 (CCN1/Cyr61) is a prompt response transcription product activated by growth factors. As a member of the CCN family, it mediates cell survival, proliferation, differentiation, migration, adhesion and synthesis of the extracellular matrix by binding directly to the integrins and heparin sulfate proteoglycans or activating multiple signaling transduction pathways. It has previously been demonstrated that CCN1/Cyr61 exhibits an important role in the female reproductive system during embryogenesis and tumorigenesis. However, the functions of CCN1/Cyr61 in the female reproductive system have not been systematically investigated, therefore, the primary aim of the present review is to introduce the role and function of CCN1/Cyr61 in the female reproductive system. The current review presents the molecular structure and biological function of CCN1/Cyr61 and provides detailed data on its expression pattern and contribution to the female reproductive system, including the role in embryogenesis and tumorigenesis.

Abstract
Tumor resistance to endocrine therapy triggers estrogen-independent cancer progression, which is a major obstacle to the successful treatment of hormone receptor positive breast cancer (BC). The underlying molecular mechanisms of endocrine resistance are not fully understood yet. The matricellular protein cysteine-rich angiogenic inducer 61 (Cyr61) is associated with tumor invasiveness and the induction of tumorigenesis in various malignancies in vivo and the induction of estrogen-independence and endocrine therapy resistance in BC. The present study evaluated the potential effects and clinical relevance of Cyr61 expression levels in 67 patients with primary non-metastatic BC. Immunohistochemical analysis of formalin-fixed paraffin-embedded tissue sections was performed, and the association between Cyr61 protein expression and clinicopathological factors and survival was analyzed. Cyr61 overexpression was revealed to be significantly associated with a positive estrogen receptor (ER)/progesterone receptor (PR) status (P=0.016) and to the molecular subtype of BC (P=0.039). Compared with patients without Cyr61 overexpression, patients with Cyr61 overexpression exhibited an increased recurrence rate (30.6 vs. 22.6%) and decreased long-term survival (10-year overall survival, 62.9 vs. 69.7%); however, these associations did not reach statistically significant levels in Cox regression model analysis. Similar results were identified in the subgroup analysis of patients with ER/PR positive BC. These results indicate that Cyr61 serves a role in the development of endocrine therapy resistance in BC and is thus a potential therapeutic target to overcome endocrine therapy resistance. However, additional long-term survival analyses with large patient populations are required.

Abstract
We aimed to investigate the effects and regulatory mechanism of microRNA-3941 (miR-3941) in the progression of breast cancer. The expression of miR-3941 and insulin-like growth factor 1 (IGF-1) was determined in breast cancer tissues and cell lines. A miR-3941 mimics, inhibitor, and scramble RNA were individually transfected into the cancer cells. Then, the effects of overexpression and suppression of miR-3941 on cell viability, migration, and invasion, as well as on the expression of epithelial-mesenchymal transition (EMT)-related proteins (E-cadherin, N-cadherin, and vimentin) were further investigated. In addition, luciferase reporter analysis was performed to confirm whether IGF-1 was the potential target of miR-3941. Small interfering RNA targeting IGF-1 was transfected into the cells to further investigate whether miR-3941 regulated the breast cancer cell migration and invasion by targeting IGF-1. The inverse expression of miR-3941 (downregulated) and IGF-1 (upregulated) was observed in the breast cancer tissues and cells. The overexpression of miR-3941 significantly inhibited the breast cancer cell viability and suppressed cell migration and invasion. In addition, IGF-1 was confirmed as the target of miR-3941, and IGF-1 expression was negatively regulated by miR-3941. The knockdown of IGF-1 significantly reversed the inhibitory effects of miR-3941 overexpression on cell migration, invasion, and the EMT-related proteins. Our results indicate that miR-3941 is downregulated in breast cancer cells, and the downregulation of miR-3941 may promote breast cancer cell proliferation, migration, and invasion through not targeting IGF-1 expression. miR-3941 and IGF-1 may serve as diagnostic markers or potential targets for breast cancer treatment.

Abstract
Long noncoding RNAs (lncRNAs) are a class of noncoding RNAs longer than 200 nucleotides. They were long regarded as transcription noise for their low expression and non-protein coding features. Recent published reports indicate that lncRNAs are involved in virtually every aspect of human biology. We aimed to profile the endometrial lncRNA expression pattern in women with recurrent implantation failure (RIF) and predict the function of the genes of the dysregulated lncRNA transcripts. Endometrial samples (24) were collected during window of implantation (14 RIF women and 10 women who conceived after embryo transfer). For the microarray study, 7 RIF endometrium and 5 control endometrium were selected, and quantitative real-time PCR (RT-qPCR) was performed on the rest of the endometrial samples to validate the microarray results. After that, lncRNA-mRNA co-expression analysis, GO analysis, KEGG analysis, and lncRNA-transcript factor (TF) analysis were carried out to analyze the gene functions of the dysregulated lncRNA transcripts. We detected a total of 197 lncRNA transcripts that were dysregulated in RIF endometrium compared with the control group. The relative expression levels of eight selected lncRNA transcripts were validated by RT-qPCR and were in accordance with the microarray outcomes. GO and KEGG analyses revealed that the coexpressed mRNA transcripts were involved in pathways that may affect endometrial receptivity such as cell adhesion. The lncRNA target predictions provided potential TF targets of the dysregulated lncRNA transcripts. Our results indicate that lncRNA expression profiles of RIF endometrium were different from that of normal receptive endometrial, suggesting that lncRNAs may regulate endometrial receptivity. ABBREVIATIONS GO: Gene Oncology; GFs: growth factors; KEGG: Kyoto Encyclopedia of Genes and Genomes; lncRNAs: long noncoding RNAs; PCA3: prostate cancer antigen 3; RT-qPCR: quantitative real-time PCR; RIF: recurrent implantation failure; STK: serine/threonine kinase; TF: transcription factor; WOI: window of implantation.

Abstract
BACKGROUND Melatonin has oncostatic actions and IL-25 is active in inflammatory processes that induce apoptosis in tumor cells AIM: The aim of this study was to evaluate melatonin and IL-25 in metastatic (CF-41) and non-metastatic (CMT-U229) canine mammary tumor cells cultured as monolayers and tridimensional structures. MATERIALS AND METHODS The cells were treated with melatonin, IL-25 and IL-17B silencing gene and performed cell viability, gene and protein expression of caspase-3 and VEGFA (Vascular endothelial growth factor A) and an apoptosis membrane protein array. RESULTS Treatment with 1 mM of melatonin reduced cell viability of both tumor cell lines, all treatments alone and combined significantly increased caspase-3 cleaved and proteins involved in the apoptotic pathway and reduced pro-angiogenic VEGFA, confirming the effectiveness of these potential promising treatments. CONCLUSION This is the first study evaluating the potential use of these strategies in CF-41 and CMT-U229 cell lines and together encourages subsequent in vitro and in vivo studies for further exploration of clinical applications.

Abstract
Regulation of matrix metalloproteinases (MMPs) by collagen in the fibroblast-like synoviocytes (FLSs) plays a critical role in joint destruction in rheumatoid arthritis (RA). Our previous study indicated that discoidin receptor 2 (DDR2) mediated collagen upregulation of MMPs. However, the precise underlying mechanism remains unclear. We report here that CYR61, a secreted, extracellular matrix-associated signaling protein which is capable of regulating a broad range of cellular activities, including cell adhesion, migration, proliferation, and apoptosis, is significantly upregulated in collagen II-stimulated RA FLS. Further studies found that collagen II-activated phosphorylated-DDR2 induces CYR61 through activation of transcription factor activator protein 1 (AP-1). The elevated CYR61, in turn, accelerates MMP1 production via ETS1 (ETS proto-oncogene 1). In addition, CYR61 significantly promotes FLS invasion and migration. Blockade of CYR61 by an adenovirus expressing CYR61 shRNA (Ad-shCYR61) in vivo remarkably ameliorated the severity of arthritis, reduced inflammatory cytokine secretion, and attenuated bone erosion as detected by micro-computed tomography (μCT), in collagen-induced arthritis (CIA) rats. Taken together, we uncovered the Collagen II-DDR2-AP-1-CYR61-ETS1-MMP1 loop in RA FLS. In which, CYR61 acts as a hinge to promote cartilage damage through regulating FLS invasion, migration, and MMP1 production and the inflammatory cascade in RA. Thus, CYR61 may be a promising diagnostic and therapeutic target for RA treatment. © 2016 American Society for Bone and Mineral Research.

Leyh B, Dittmer A, Lange T, Martens JWM, Dittmer J. Stromal cells promote anti-estrogen resistance of breast cancer cells through an insulin-like growth factor binding protein 5 (IGFBP5)/B-cell leukemia/lymphoma 3 (Bcl-3) axis. Oncotarget 2016; 6:39307-28. [PMID: 26515727 PMCID: PMC4770774 DOI: 10.18632/oncotarget.5624] [Citation(s) in RCA: 28] [Impact Index Per Article: 3.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/12/2015] [Accepted: 10/09/2015] [Indexed: 12/27/2022] Open
Abstract
There is strong evidence that stromal cells promote drug resistance of cancer. Here, we show that mesenchymal stem cells (MSCs) and carcinoma-associated fibroblasts (CAFs) desensitize ERα-positive breast cancer cells to the anti-estrogen fulvestrant. In search for the mechanism, we found that MSCs and CAFs similarly increased the activity of the PI3K/AKT and the JAK/STAT3 pathways and upregulated the expression of integrin β1, IGF1R, HIF1α, CAIX and Bcl-3 in MCF-7 cells. Further analyses revealed that MSCs and CAFs coordinately induce these changes by triggering the downregulation of IGFBP5. Loss of IGFBP5 in MCF-7 cells was an early and long-lasting event in response to MSCs and CAFs and was accompanied by growth stimulation both in the absence and presence of fulvestrant. The growth-stimulatory effect in the absence of fulvestrant could be attributed to PI3K/AKT pathway activation and could be mimicked by insulin. The growth-promoting effect in the presence of fulvestrant depended upon the upregulation of Bcl-3. By cRNA microarray analysis we identified additional IGFBP5 targets, of which two (KLHL4 and SEPP1) were inversely regulated by IGFBP5 and Bcl-3. BT474 cells also responded to stromal cells by downregulating IGFBP5 and upregulating the P-AKT, Bcl-3 and IGF1R levels, whereas T47D cells did not show any of these responses. In conclusion, our data suggest that, by targeting IGFBP5 expression in ERα-positive breast cancer cells, such as MCF-7 cells, MSCs and CAFs are able to orchestrate a variety of events, particularly activation of the PI3K/AKT pathway, upregulation of Bcl-3 expression and desensitization to anti-estrogen.

Effects of High-Order Interactions among IGFBP-3 Genetic Polymorphisms, Body Mass Index and Soy Isoflavone Intake on Breast Cancer Susceptibility. PLoS One 2016; 11:e0162970.

Abstract
Background Polymorphisms of IGF-1 and IGFBP-3 and environmental factors may work together to influence insulin-like growth factor (IGF) levels and thus breast cancer (BC) risk. However, very few studies have investigated high-order interactions among these variables. Methods A total of 277 newly diagnosed BC cases and 277 controls were recruited between October 2010 and July 2012. We collected each participant's demographic characteristics, dietary intake, and blood sample. IGF-1 rs1520220 and IGFBP-3 rs2854744 were then genotyped. A multi-analytic strategy combining unconditional logistic regression (ULR), generalized multifactor dimensionality reduction (GMDR), and classification and regression tree (CART) approaches was applied to systematically identify the interactions of the two single nucleotide polymorphisms (SNPs), body mass index (BMI), and daily intake of soy isoflavone (DISI) on BC susceptibility. Results In GMDR analyses, high-order interactions among BMI, DISI, and SNP rs2854744 were identified among overall and postmenopausal women. We also found significant dosage effects on BC risk with an increasing number of exposure factors, namely carrying the rs2854744 AA genotype, DISI <9.85 mg/day, and BMI ≥24 kg/m2 (Ptrend<0.05). Similarly, in CART analyses, compared with individuals having BMI<24kg/m2, DISI<9.85 mg/day, and the rs2854744 CC+CA genotype, BC risk increased significantly for those carrying the rs2854744 AA genotype, with BMI<24 kg/m2 and DISI<9.85 mg/day (OR = 1.95, 95%CI: 1.03–3.69), and also for those with BMI≥24kg/m2 and DISI<9.85 mg/day (OR = 2.13, 95%CI: 1.00–4.51). Similar interaction effects were observed among postmenopausal women. Conclusions This study suggests high-order interactions of the IGFBP-3 rs2854744 AA genotype, BMI≥24kg/m2, and DISI<9.85 mg/day on increased BC risk, particularly among postmenopausal women.

Abstract
Hepatocellular carcinoma (HCC) results from an underlying chronic liver inflammatory disease, such as chronic hepatitis B or C virus infections, and the general prognosis of patients with HCC still remains extremely dismal because of the high frequency of HCC metastases. Throughout the process of tumor metastasis, tumor cells constantly communicate with the surrounding microenvironment and improve their malignant phenotype. Therefore, there is a strong rationale for targeting the tumor microenvironment as primary treatment of HCC therapies. Recently, CCN family proteins have emerged as localized multitasking signal integrators in the inflammatory microenvironment. In this review, we summarize the current knowledge of CCN family proteins in inflammation and the tumor. We also propose that the CCN family proteins may play a central role in signaling the tumor microenvironment and regulating the metastasis of HCC.

Abstract
Previously, we characterized the biological properties of Akbu-LAAO, a novel L-amino acid oxidase from Agkistrodon blomhoffii ussurensis snake venom (SV). Current work investigated its in vitro anti-tumor activity and underlying mechanism on HepG2 cells. Akbu-LAAO inhibited HepG2 growth time and dose-dependently with an IC50 of ~38.82 μg/mL. It could induce the apoptosis of HepG2 cells. Akbu-LAAO exhibited cytotoxicity by inhibiting growth and inducing apoptosis of HepG2 as it showed no effect on its cell cycle. The inhibition of Akbu-LAAO to HepG2 growth partially relied on enzymatic-released H2O2 as catalase only partially antagonized this effect. cDNA microarray results indicated TGF-β signaling pathway was linked to the cytotoxicity of Akbu-LAAO on HepG2. TGF-β pathway related molecules CYR61, p53, GDF15, TOB1, BTG2, BMP2, BMP6, SMAD9, JUN, JUNB, LOX, CCND1, CDK6, GADD45A, CDKN1A were deregulated in HepG2 following Akbu-LAAO stimulation. The presence of catalase only slightly restored the mRNA changes induced by Akbu-LAAO for differentially expressed genes. Meanwhile, LDN-193189, a TGF-β pathway inhibitor reduced Akbu-LAAO cytotoxicity on HepG2. Collectively, we reported, for the first time, SV-LAAO showed anti-tumor cell activity via TGF-β pathway. It provides new insight of SV-LAAO exhibiting anti-tumor effect via a novel signaling pathway.

Crizotinib-induced antitumour activity in human alveolar rhabdomyosarcoma cells is not solely dependent on ALK and MET inhibition. JOURNAL OF EXPERIMENTAL & CLINICAL CANCER RESEARCH : CR 2015; 34:112. [PMID: 26445453 PMCID: PMC4596370 DOI: 10.1186/s13046-015-0228-4] [Citation(s) in RCA: 36] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 06/11/2015] [Accepted: 09/29/2015] [Indexed: 12/30/2022]
Abstract
Background Rhabdomyosarcoma (RMS) is the most commonly diagnosed malignant soft tissue tumour in children and adolescents. Aberrant expression of Anaplastic Lymphoma Kinase (ALK) and MET gene has been implicated in the malignant progression of RMS, especially in the alveolar subtype. This observation suggests that crizotinib (PF-02341066), a kinase inhibitor against ALK and MET, may have a therapeutic role in RMS, although its antitumour activity in this malignancy has not yet been studied. Methods RH4 and RH30 alveolar RMS (ARMS) cell lines were treated with crizotinib and then assessed by using proliferation, viability, migration and colony formation assays. Multiple approaches, including flow cytometry, immunofluorescence, western blotting and siRNA-based knock-down, were used in order to investigate possible molecular mechanisms linked to crizotinib activity. Results In vitro treatment with crizotinib inhibited ALK and MET proteins, as well as Insulin-like Growth Factor 1 Receptor (IGF1R), with a concomitant robust dephosphorylation of AKT and ERK, two downstream kinases involved in RMS cell proliferation and survival. Exposure to crizotinib impaired cell growth, and accumulation at G2/M phase was attributed to an altered expression and activation of checkpoint regulators, such as Cyclin B1 and Cdc2. Crizotinib was able to induce apoptosis and autophagy in a dose-dependent manner, as shown by caspase-3 activation/PARP proteolytic cleavage down-regulation and by LC3 activation/p62 down-regulation, respectively. The accumulation of reactive oxygen species (ROS) seemed to contribute to crizotinib effects in RH4 and RH30 cells. Moreover, crizotinib-treated RH4 and RH30 cells exhibited a decreased migratory/invasive capacity and clonogenic potential. Conclusions These results provide a further insight into the molecular mechanisms affected by crizotinib in ARMS cells inferring that it could be a useful therapeutic tool in ARMS cancer treatment.

Abstract
One of the great challenges of small cell lung cancer (SCLC) treatment is identifying patients at high risk for recurrence after surgical resection and chemotherapy. We examined Eps15 homology domain 1 (EHD1) protein expression in paraffin sections of 85 resected SCLC tissues, metastatic lymph nodes and normal bronchial epithelial tissues using immunohistochemistry to study the correlation between EHD1 expression and patient clinicopathological features. Within these variables, disease free survival (DFS) analyzed by the log-rank test was constructed using the multivariate Cox proportional hazards regression model and Kaplan-Meier analysis. Immunohistochemistry results showed that EHD1 protein was significantly increased in SCLC tissues compared with normal tissues (P < 0.001). Moreover, EHD1 expression was positively correlated with tumor size (P = 0.019). Multivariate Cox proportional hazards model analysis showed that EHD1 expression (P = 0.047; HR, 1.869; 95% CI, 1.008-3.466) and American Joint Committee on Cancer (AJCC) status (P < 0.001; HR, 1.412; 95% CI, 1.165-1.711) were independent prognostic indicators of DFS. In conclusion, these data demonstrated a remarkable correlation between the cytoplasmic expression of EHD1 protein and adverse prognosis in patients receiving early-stage cisplatin treatment for resected SCLC.

Abstract
Breast cancer is the most common type of cancer for women worldwide with a lifetime risk amounting to a staggering total of 10%. It is well established that the endogenous synthesis of insulin-like growth factor (IGF) and epidermal growth factor (EGF) polypeptide growth factors are closely correlated to malignant transformation and all the steps of the breast cancer metastatic cascade. Numerous studies have demonstrated that both estrogens and growth factors stimulate the proliferation of steroid-dependent tumor cells, and that the interaction between these signaling pathways occurs at several levels. Importantly, the majority of breast cancer cases are estrogen receptor- (ER-) positive which have a more favorable prognosis and pattern of recurrence with endocrine therapy being the backbone of treatment. Unfortunately, the majority of patients progress to endocrine therapy resistant disease (acquired resistance) whereas a proportion of patients may fail to respond to initial therapy (de novo resistance). The IGF-I and EGF downstream signaling pathways are closely involved in the process of progression to therapy resistant disease. Modifications in the bioavailability of these growth factors contribute critically to disease progression. In the present review therefore, we will discuss in depth how IGF and EGF signaling participate in breast cancer pathogenesis and progression to endocrine resistant disease.

Abstract
Background The lack of consensus among reported gene signature subsets (GSSs) in multi-gene biomarker discovery studies is often a concern for researchers and clinicians. Subsequently, it discourages larger scale prospective studies, prevents the translation of such knowledge into a practical clinical setting and ultimately hinders the progress of the field of biomarker-based disease classification, prognosis and prediction. Methods We define all "gene identificators" (gIDs) as constituents of the entire potential disease biomarker space. For each gID in a GSS of interest ("tested GSS"/tGSS), our method counts the empirical frequency of gID co-occurrences/overlaps in other reference GSSs (rGSSs) and compares it with the expected frequency generated via implementation of a randomized sampling procedure. Comparison of the empirical frequency distribution (EFD) with the expected background frequency distribution (BFD) allows dichotomization of statistically novel (SN) and common (SC) gIDs within the tGSS. Results We identify SN or SC biomarkers for tGSSs obtained from previous studies of high-grade serous ovarian cancer (HG-SOC) and breast cancer (BC). For each tGSS, the EFD of gID co-occurrences/overlaps with other rGSSs is characterized by scale and context-dependent Pareto-like frequency distribution function. Our results indicate that while independently there is little overlap between our tGSS with individual rGSSs, comparison of the EFD with BFD suggests that beyond a confidence threshold, tested gIDs become more common in rGSSs than expected. This validates the use of our tGSS as individual or combined prognostic factors. Our method identifies SN and SC genes of a 36-gene prognostic signature that stratify HG-SOC patients into subgroups with low, intermediate or high-risk of the disease outcome. Using 70 BC rGSSs, the method also predicted SN and SC BC prognostic genes from the tested obesity and IGF1 pathway GSSs. Conclusions Our method provides a strategy that identify/predict within a tGSS of interest, gID subsets that are either SN or SC when compared to other rGSSs. Practically, our results suggest that there is a stronger association of the IGF1 signature genes with the 70 BC rGSSs, than for the obesity-associated signature. Furthermore, both SC and SN genes, in both signatures could be considered as perspective prognostic biomarkers of BCs that stratify the patients onto low or high risks of cancer development.

Abstract
Ovarian cancer is one of the most aggressive gynaecological cancers, thus understanding the different biological pathways involved in ovarian cancer progression is important in identifying potential therapeutic targets for the disease. The aim of this study was to investigate the potential roles of Protein Kinase C Zeta (PRKCZ) in ovarian cancer. The atypical protein kinase C isoform, PRKCZ, is involved in the control of various signalling processes including cell proliferation, cell survival, and cell motility, all of which are important for cancer development and progression. Herein, we observe a significant increase in cell survival upon PRKCZ over-expression in SKOV3 ovarian cancer cells; additionally, when the cells are treated with small interference RNA (siRNA) targeting PRKCZ, the motility of SKOV3 cells decreased. Furthermore, we demonstrate that over-expression of PRKCZ results in gene and/or protein expression alterations of insulin-like growth factor 1 receptor (IGF1R) and integrin beta 3 (ITGB3) in SKOV3 and OVCAR3 cells. Collectively, our study describes PRKCZ as a potential regulatory component of the IGF1R and ITGB3 pathways and suggests that it may play critical roles in ovarian tumourigenesis.

Breast Cancer Res Treat 2015; 150:427-37. [PMID: 25762476 DOI: 10.1007/s10549-015-3331-5] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/06/2015] [Accepted: 03/04/2015] [Indexed: 12/14/2022]
Abstract
This study assessed the association between glucose-lowering drug (GLD) use, including metformin, sulphonylurea derivatives and insulin, after breast cancer diagnosis and breast cancer-specific and all-cause mortality. 1763 breast cancer patients, diagnosed between 1998 and 2010, with type 2 diabetes were included. Cancer information was retrieved from English cancer registries, prescription data from the UK Clinical Practice Research Datalink and mortality data from the Office of National Statistics (up to January 2012). Time-varying Cox regression models were used to calculate HRs and 95 % CIs for the association between GLD use and breast cancer-specific and all-cause mortality. In 1057 patients with diabetes before breast cancer, there was some evidence that breast cancer-specific mortality decreased with each year of metformin use (adjusted HR 0.88; 95 % CI 0.75-1.04), with a strong association seen with over 2 years of use (adjusted HR 0.47; 95 % CI 0.26-0.82). Sulphonylurea derivative use for less than 2 years was associated with increased breast cancer-specific mortality (adjusted HR 1.70; 95 % CI 1.18-2.46), but longer use was not (adjusted HR 0.94; 95 % CI 0.54-1.66). In 706 patients who developed diabetes after breast cancer, similar patterns were seen for metformin, but sulphonylurea derivative use was strongly associated with cancer-specific mortality (adjusted HR 3.64; 95 % CI 2.16-6.16), with similar estimates for short- and long-term users. This study provides some support for an inverse association between, mainly long-term, metformin use and (breast cancer-specific) mortality. In addition, sulphonylurea derivative use was associated with increased breast cancer-specific mortality, but this should be interpreted cautiously, as it could reflect selective prescribing in advanced cancer patients.
