Abstract
Irisin, an adipokine, regulates differentiation and phenotype in various cell types including myocytes, adipocytes, and osteoblasts. Circulating irisin concentration increases throughout human pregnancy. In pregnancy disorders such as preeclampsia and gestational diabetes mellitus, circulating irisin levels are reduced compared to healthy controls. To date, there are no data on the role and molecular function of irisin in the human placenta or its contribution to pathophysiology. Aberrant trophoblast differentiation is involved in the pathophysiology of preeclampsia. The current study aimed to assess the molecular effects of irisin on trophoblast differentiation and function. First-trimester placental explants were cultured and treated with low (10 nM) and high (50 nM) physiological doses of irisin. Treatment with irisin dose-dependently increased both in vitro placental outgrowth (on Matrigel™) and trophoblast cell-cell fusion. Adenosine monophosphate-activated protein kinase (AMPK) signaling, an important regulator of cellular energy homeostasis that is involved in trophoblast differentiation and pathology, was subsequently investigated. Here, irisin exposure induced placental AMPK activation. To determine the effects of irisin on trophoblast differentiation, two trophoblast-like cell lines, HTR-8/SVneo and BeWo, were treated with irisin and/or a specific AMPK inhibitor (Compound C). Irisin-induced AMPK phosphorylation in HTR-8/SVneo cells. Additionally, as part of the differentiation process, integrin switching from α6 to α1 occurred as well as increased invasiveness. Overall, irisin promoted differentiation in villous and extravillous cell-based models via AMPK pathway activation. These findings provide evidence that exposure to irisin promotes differentiation and improves trophoblast functions in the human placenta that are affected in abnormal placentation.

Abstract
Aim: There is much evidence of an association between cancer and irisin that is an adipokine. This study researched on the relationship between prostate cancer (PCa) and irisin levels, and whether irisin can be used as a biomarker in the diagnosis of PCa. Materials and Methods: For the study groups, 50 primary PCa patients and 30 healthy male subjects were included in the PCa and healthy control groups, respectively. All volunteers in the healthy control group were screened for prostate cancer and other malignancies and chronic diseases. Volunteers who were determine to be completely healthy were included for healthy control group. In the serum samples of the subjects were measured free PSA, total PSA and irisin levels. Irisin levels were compared separately in terms of the Gleason scores and T stage. In addition to intergroup comparisons, the ROC curve for the irisin was plotted and power analysis was performed. Results: Free and total PSA levels in the PCa group were significantly higher compared to the healthy control group (p<0.05). In addition, irisin levels in the PCa group were significantly lower than in the healthy control group (p<0.05). There was no significant difference between irisin levels in the groups classified in terms of Gleason scores (p>0.05). When the cut-off value was taken as 8.1, the sensitivity and specificity of irisin for PCa were as 80.5% and 90%, respectively. Conclusion: The results of this study indicate that the levels of irisin in the PCa group are considerably reduced and irisin may be used as a biomarker as well as free and total PSA.

Abstract
In the last few decades, there has been notable progress in understanding the molecular and cellular basis of the complex process involved in cancer. In this context, tumor-promoting inflammation, dysregulation of apoptotic signaling, tissue invasion and metastasis, and cancer microenvironment have recently attracted interest from researchers. Irisin is a hormone released by muscles during exercise and it directly acts on key functional cells involving energy metabolism and homeostasis. Recently, many studies have reported the anticancer effect of irisin against different types of cancer. Translation of these findings to clinical practice for the diagnosis and treatment of several types of cancer is urgently required. In this review, we summarized preclinical and clinical studies on the anticancer effects of irisin in various types of cancer, and also discussed the mechanisms activated by irisin to suppress cancer pathogenesis. We further discussed the serum level of irisin related to different types of cancer to understand more clearly the association between irisin concentration and tumor burden. This review may serve as a solid foundation for researchers and physicians to support basic and clinical studies on irisin as a promising strategy for early diagnosis and treatment of a various types of cancers.

Abstract
BACKGROUND Egypt is among the countries with the highest incidence of bladder cancer (BC). Adipokines involved in BC development. This study aimed to examine the diagnostic and prognostic roles of irisin in BC through its function as an adipokine. PATIENTS AND METHODS This study included 150 subjects; 75 patients newly diagnosed as BC and 75 apparently healthy subjects. Serum irisin levels were quantified by enzyme-linked immunosorbent assay. RESULTS Serum irisin levels exhibited significantly lower levels in BC patients compared to controls (1.07 [0.51-1.96] and 1.8 [0.5-2.44] µg/mL), respectively (P < 0.001). Serum irisin was positively correlated with BMI (r = 0.386, P = 0.001) and negatively correlated with serum cholesterol (r = -0.58, P < 0.0001). Irisin had 74.7% sensitivity and 90.7% specificity at a cutoff point of ≤1.2 µg/mL. Serum irisin levels reduction can predict the BC stages, when adjusted for BMI and serum cholesterol level, serum irisin had an adjusted odds ratio of 14 (P = 0.001). Low serum irisin patients had a higher mortality rate when compared to those with high levels (38.2% vs 5%). CONCLUSION BC patients had significantly lower levels of serum irisin. Serum irisin showed acceptable performance criteria in BC diagnosis. It had a limited role in BC grading but showed a decreasing trend in different BC stages. Serum irisin seems to be an excellent diagnostic and prognostic marker for BC.

Abstract
OBJECTIVE Osteoporosis has imposed a heavy socioeconomic burden worldwide, especially in postmenopausal women. As a newly found protein, irisin has an important physiological role in bone metabolism. This meta-analysis intends to identify the association between circulating irisin levels and osteoporosis. METHODS This meta-analysis was conducted following the Meta-analysis of Observational Studies in Epidemiology (MOOSE) guideline. A comprehensive search of five databases was performed from inception to January 2019. Studies with original date on middle-aged and older participants were included. Data were analyzed according to study characteristics and heterogeneity between studies. The quality of each study and the presence of publication bias were assessed by Newcastle-Ottawa score (NOS) and normal quantile plot. RESULTS Seven studies, with a total of 1,018 participants, conducted in four countries, were included. Six of them were identified as high-quality research. Five studies included postmenopausal women, and two studies included both men and women. Possible publication bias was found in the analysis of irisin and osteoporosis. Pooled analysis indicated decreased irisin levels in osteoporotic participants (mean difference -87.91, 95% CI, -92.56 to -83.25). Subgroup analysis revealed an even lower level of irisin in postmenopausal women and in participants with a history of fractures. Analysis on associations between irisin and femoral neck or lumbar spine bone mineral density showed a weak positive correlation. CONCLUSIONS The findings of this analysis suggested that circulating irisin levels were decreased in middle-aged and older participants with osteoporosis. Irisin was positively correlated with bone mineral density.

Abstract
Background: Cancer stem cells (CSCs) are associated with tumor development, chemoresistance, recurrence, metastasis, and even prognosis. Interleukin (IL)-6 overexpression has been implicated in the development of various cancers, including osteosarcoma. This study aimed to investigate the role of IL-6 in modulating clinicopathological features, malignant traits, and stemness in osteosarcoma, and to determine the mechanisms underlying IL-6-mediated osteosarcoma progression. Methods: Patients with osteosarcoma (n = 54) and healthy controls (n = 50) were selected. No patients received any pre-operative cancer treatment. Serum levels of IL-6 were determined in patients with osteosarcoma by ELISA and their relationship with pathological features and prognosis analyzed. The 3-(4,5-dimethyl -2-thiazolyl)- 2,5-diphenyl-2H-tetrazolium bromide (MTT) and colony formation assays were used to evaluate cell proliferation, transwell assays were used to assess the invasive potential of cells, and cell migration rates were analyzed using a wound healing assay. Tumor self-renewal was detected using a spheroid formation assay and CD133 and CD44 expression assessed by flow cytometry. Protein levels of NANOG, SOX2, OCT3/4, OPN, and epithelial-to-mesenchymal transition (EMT)-related markers, and the phosphorylation status of STAT3, were determined by western blotting. Finally, cell viability was determined with or without cisplatin (cis-dichlorodiammineplatinum [DDP])/adriamycin (ADR) treatment. Xenograft tumor models were established by subcutaneous injection of osteosarcoma spheroids, with or without IL-6. Results: Serum IL-6 levels were higher in osteosarcoma patients than controls. There was no significant association of serum IL-6 level with age, sex and tumor size; however, it was associated with TNM stage, and lung metastasis (P < 0. 05). IL-6 significantly increased proliferation and colony formation of osteosarcoma cells, and enhanced their invasion and migratory potential, thus promoting an EMT-like phenotype and elevated chemoresistance of to DDP/ADR. Spheroid size/proportion of CD133+CD44+ cells and SOX2, OCT3/4, and NANOG protein levels were elevated by IL-6 treatment in a time-dependent manner; however, IL-6 did not substantially influence any of these features in hFOB 1.19 and T98G cells. Knockdown of IL-6 reduced cell viability, colony formation, and invasion/migration ability, and reversed EMT, whereas it increased chemosensitivity to DDP/ADR. Blocking IL-6 expression with siRNA also caused loss of stemness, including reducing self-renewal ability, and reduced the proportion of CD133/CD44-positive cells, and expression of stemness-related genes. Pretreatment with the STAT3 inhibitor, S3I-201, decreased sphere size, and downregulated NANOG, SOX2, and OCT3/4 protein levels, compared with IL-6 treatment alone. Furthermore, OPN levels were elevated in response to IL-6 and an anti-OPN antibody effectively blocked IL-6-induced spheroid formation and STAT3 phosphorylation. In vivo, tumor size and weight were higher in IL-6 treated mice than controls. Conclusions: IL-6 mediates promotion of osteosarcoma spheroid stemness by activating OPN/STAT3 signaling.

Abstract
Introduction Irisin is a newly identified cytokine that has gained increasing attention because of its potential therapeutic applications in metabolic diseases and human cancers. Recently, accumulating evidence indicates that irisin plays an important role in the development and metastasis of various tumors. The aim of this study was to evaluate the effects and underlying mechanisms of irisin on malignant growth of pancreatic cancer cells. Materials and methods The anti-proliferative effect of irisin was examined using the CCK-8 assay. Irisin-induced apoptosis was determined by the annexin V-FITC/PI staining assay. The effects of irisin on cell migration and invasion were assessed using the scratch-induced wound healing assay and transwell invasion assay, respectively. The expression and phosphorylation of signaling proteins were detected by Western blot analysis. Results Our results showed that irisin inhibited cell proliferation and induced apoptosis of pancreatic cancer cells in a dose-dependent manner. In addition, irisin decreased the migration and invasion of pancreatic cancer cells. Finally, Western blot analysis revealed that irisin downregulated the PI3K/AKT signaling pathway. Conclusion Our findings suggest that irisin is a novel therapeutic agent for pancreatic cancer.

Abstract
Sedentary life style is considered to be an independent risk factor for many disorders, including development of type 2 diabetes, obesity, immune dysfunction, asthma, and neurological or coronary heart disease. Irisin is released from myocytes during physical activity, and acts as a link between muscles and other tissues and organs. This myokine is produced as a result of proteolytic cleavage of FNDC5 protein present in the membrane of myocytes. Secretion of irisin is regulated by N-linked oligosaccharides attached to the protein molecule. The two N-glycan molecules, which constitute a significant part of the irisin glycoprotein, regulate the browning of adipocytes, which is the most important function of irisin. A receptor specific for irisin has still not been discovered. In some tissues irisin probably acts via integrins, which are widely expressed transmembrane receptors. Many studies have confirmed the multifunctional role of irisin and the beneficial effects of this molecule on body homeostasis. Irisin reduces systemic inflammation, maintains the balance between resorption and bone formation, and modulates metabolic processes and the functioning of the nervous system. It suppresses the expression and release of pro-inflammatory cytokines in obese individuals and attenuates inflammation in adipose tissue. The impact of irisin on cancer cell proliferation, migration, and invasion has also been demonstrated in numerous studies, which proves its role in carcinogenesis. Owing to these pleiotropic and beneficial properties, irisin may be a potential option to prevent and treat civilization-related diseases which are, nowadays, considered to be the major health problems in Western societies.

Abstract
Background Irisin, a myokine released from skeletal muscle following exercise, has been shown to affect the proliferation of some cancer cells and chemosensitivity of anticancer drugs like doxorubicin (DOX). However, the effects of irisin on chemosensitivity in pancreatic cancer (PC) cells have not been studied. Material/Methods In this study, the effects of irisin co-treatment with DOX or gemcitabine (GEM) on MIA PaCa-2, BxPC-3 PC cells, and H9c2 cardiomyocytes were investigated. MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay, flow cytometry, and TUNEL (TdT-mediated dUTP nick-end labeling) assays were conducted to evaluate cytotoxicity induced by DOX or GEM. Fluorescence microscopy and flow cytometry experiments were performed to assess the intracellular accumulation of DOX. Cellular levels of apoptosis-related protein expression and protein phosphorylation were determined by Western blot analyses. Results The results showed that irisin can increase the chemosensitivity of PC cells to DOX or GEM. The analyses of apoptosis indicated that irisin enhances DOX-induced cellular apoptosis by increasing the expression of cleaved PARP (poly ADP-ribose polymerase) and cleaved caspase-3, and reducing the expression of B cell lymphoma/lewkmia-2 (BCL-2) and B cell lymphoma-extra large (BCL-xL) in PC cells but not in H9c2 cells. Irisin attenuated serine/threonine kinase AKT (protein kinase B/PKB) phosphorylation and inhibited the activation of nuclear factor κB (NF-κB) signaling in PC cells. Conclusions Irisin can potentiate the cytotoxicity of doxorubicin in PC cells without increasing cardiotoxicity, possibly through inactivating the PI3K/AKT/NF-κB signaling pathway.

Abstract
Ion channels have recently emerged as stable biomarkers and anticancer targets particularly when the applications of the currently available therapeutic regimens are limited, as in case of osteosarcoma, a malignant bone tumor. Here, we evaluated the expression of TTYH2, a presumably calcium-activated chloride channel, in a human osteosarcoma cell line U2OS. We used small-interfering RNA (siRNA)-mediated gene silencing to demonstrate the downregulation in the expression of TTYH2 that resulted in the decrease in the invasion and migration, but not proliferation, of U2OS cells. The expression levels of Slug and ZEB1, the transcription factors involved in epithelial-mesenchymal transition, significantly reduced after TTYH2 silencing. Based on these results, we suggest that TTYH2 may serve as a novel target for the treatment of osteosarcoma.

Overexpression of carbonyl reductase 1 inhibits malignant behaviors and epithelial mesenchymal transition by suppressing TGF-β signaling in uterine leiomyosarcoma cells. Oncol Lett 2019; 18:1503-1512. [PMID: 31423217 PMCID: PMC6607169 DOI: 10.3892/ol.2019.10429] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/27/2018] [Accepted: 05/22/2019] [Indexed: 12/31/2022] Open
Abstract
Carbonyl reductase 1 (CBR1) has been reported to be involved in cancer progression. Recently, we found that CBR1 overexpression inhibited malignant behaviors and the epithelial mesenchymal transition (EMT) in uterine cervical cancer. It remained unclear whether this was also the case in uterine leiomyosarcoma (uLMS), which is derived from mesenchymal cells and is a much more malignant gynecological tumor. A number of previous studies suggested that malignant behaviors are associated with EMT, even in mesenchymal malignant tumors. In the present study, we investigated whether CBR1 inhibits malignant behaviors and EMT in uLMS. We established clones of uLMS cells (SKN cells) and uterine sarcoma cells (MES-SA cells) that overexpressed CBR1. Cell proliferative, migratory and invasive activities were suppressed by CBR1 overexpression, accompanied by increases in the expressions of epithelial markers (E-cadherin and cytokeratin) and decreases in the expressions of mesenchymal markers (N-cadherin and fibronectin), suggesting that CBR1 overexpression inhibits malignant behaviors and EMT in uLMS cells. In addition, transforming growth factor-β (TGF-β) production and the subsequent signaling and phosphorylation of Smad were suppressed in the clones. To investigate the association between TGF-β and EMT, SKN cells were treated with TGF-β or a TGF-β receptor blocker (SB431542). EMT was promoted by TGF-β and inhibited by SB431542. In conclusion, this is the first study, to the best of the authors' knowledge, showing that CBR1 overexpression inhibits malignant behaviors and EMT in uLMS cells. The present study provided novel insight demonstrating that the suppressive effect of CBR1 is mediated through TGF-β signaling.

Abstract
Irisin is a recently discovered myokine that plays an important role in fat metabolism through the browning of white adipose tissue. This myokine is usually secreted after exercise by improving energy balance and has shown great potential as a possible treatment for some metabolic diseases such as obesity, insulin resistance, and inflammation. Obesity has been linked to a higher incidence of some cancers. Furthermore, some studies have shown irisin to have direct positive effects on different types of cancers. Although it is hard to relay conclusions from in vitro to in vivo studies, the majority of the available data favor irisin as a potential substance for cancer regression through reducing proinflammatory markers linked to obesity. However, some controversies remain on the exact benefits of irisin on cancer with some studies showing no or even a negative effect of irisin on cancer. This review summarizes these 2 differing viewpoints and synthesizes them to form a clearer picture of exercise-induced irisin's effects on cancer.

Abstract
Irisin, a recently identified myokine that is released from skeletal muscle following exercise, regulates body weight and influences various metabolic diseases such as obesity and diabetes. In this study, human recombinant nonglycosylated P-irisin (expressed in Escherichia coli prokaryote cell system) or glycosylated E-irisin (expressed in Pichia pastoris eukaryote cell system) were compared to examine the role of recombinant irisin against pancreatic cancer (PC) cells lines, MIA PaCa-2 and Panc03.27. MTT [3-(4, 5-dimethylthiazol-2-yl)-2, 5-di phenyltetrazolium bromide] and cell colony formation assays revealed that irisin significantly inhibited the growth of MIA PaCa-2 and Panc03.27 in a dose-dependent manner. Irisin also induced G1 arrest in both cell lines. Scratch wound healing and transwell assays revealed that irisin also inhibited the migration of PC cells. Irisin reversed the activity of epithelial–mesenchymal transition (EMT) while increasing E-cadherin expression and reducing vimentin expression. Irisin activated the adenosine monophosphate-activated protein kinase (AMPK) pathway and suppressed the mammalian target of rapamycin (mTOR) signaling. Besides, our results suggest that irisin receptors exist on the surface of human MIA PaCa-2 and Panc03.27 cells. Our results clearly demonstrate that irisin suppressed PC cell growth via the activation of AMPK, thereby downregulating the mTOR pathway and inhibiting EMT of PC cells.

Abstract
Irisin is a hormone-like molecule mainly released by skeletal muscles in response to exercise. Irisin induces browning of the white adipose tissue and has been shown to regulate glucose and lipid homeostasis. Keeping its energy expenditure and metabolic properties in view, numerous studies have focused on its therapeutic potential for the treatment of metabolic disorders like obesity and type 2 diabetes. Recently, the anti-inflammatory, anti-apoptotic and anti-oxidative properties of irisin have received a great deal of attention of the scientific society. These pathogenic processes are often associated with initiation, progression, and prognosis of numerous diseases like myocardial infarction, kidney diseases, cancer, lung injury, inflammatory bowel diseases, atherosclerosis, liver diseases, obesity and type 2 diabetes. In the current review, we present evidence regarding the anti-inflammatory, anti-apoptotic and anti-oxidative potential of irisin pertaining to various pathological conditions. Here, we explore multiple molecular pathways targeted by irisin therapy. Given the promising effects of irisin, many diseases with evident oxidative stress, inflammation and apoptosis can be targeted by irisin.

Abstract
The high incidences of bone metastasis in patients with breast cancer, prostate cancer and lung cancer still remains a puzzling issue. The "seeds and soil" hypothesis suggested that bone marrow (soil) may provide a favorable "niche" for tumor cells (seed). When seeking for effective ways to prevent and treat tumor bone metastasis, most researchers focus on tumor cells (seed) but not the bone marrow microenvironment (soil). In reality, only a fraction of circulating tumor cells (CTCs) could survive and colonize in bone. Thus, the bone marrow microenvironment could ultimately determine the fate of tumor cells that have migrated to bone. Bone marrow adipocytes (BMAs) are abundant in the bone marrow microenvironment. Mounting evidence suggests that BMAs may play a dominant role in bone metastasis. BMAs could directly provide energy for tumor cells, enhance the tumor cell proliferation, and resistance to chemotherapy and radiotherapy. BMAs are also known for releasing some inflammatory factors and adipocytokines to promote or inhibit bone metastasis. In this review, we made a comprehensive summary for the interaction between BMAs and bone metastasis. More importantly, we discussed the potentially promising methods for the prevention and treatment of bone metastasis. Genetic disruption and pharmaceutical inhibition may be effective in inhibiting the formation and pro-tumor functions of BMAs.

Abstract
The microenvironment of breast cancer comprises predominantly of adipocytes. Adipocytes drive cancer progression through the secretion adipocytokines. Adipocytes induce epithelial mesenchymal transition of breast cancer cells through paracrine IL-6/Stat3 signalling. Treatment approaches that can target adipocytes in the microenvironment and abrogate paracrine signals that drive breast cancer growth and metastasis are urgently needed. Repositioning of old drugs has become an effective approach for discovering new cancer drugs. In this study, niclosamide, an FDA approved anthelminthic drug was evaluated for its anti-breast cancer activity and its ability to inhibit adipocytes induced EMT. Niclosamide potently inhibited proliferation, migration and invasion at low concentration and induced significant apoptosis at high concentrations in human breast cancer cell lines MDA-MB-468 and MCF-7. Additionally, niclosamide reversed adipocyte-induced EMT with a correlated inhibition of IL-6/Stat3 activation and downregulation of EMT-TFs TWIST and SNAIL. Moreover, niclosamide markedly impaired MDA-MB-468 and MCF-7 migration and invasion. We further found that the inhibitory effects of niclosamide on MDA-MB-468 and MCF-7 motility was closely related to destabilization of focal adhesion complex formation. With decreased co-localization of focal adhesion kinase (FAK) and phosphorylated paxillin (pPAX). Collectively, these results demonstrate that niclosamide could be used to inhibit adipocyte-induced breast cancer growth and metastasis.
