Abstract
Polycystic ovary syndrome (PCOS) is the most prevalent endocrinopathy among females of reproductive age. Due to its unclear etiopathogenesis, it is of vital significance to take a deeper understanding of molecular mechanisms underlying PCOS. Quantitative real-time PCR (RT-qPCR) and western blot were applied for detection of gene expression and protein expression individually. Cell Counting Kit-8 (CCK-8) and colony formation assays were used for the evaluation of cell proliferation while Caspase-3/9 activity was measured for the assessment of cell apoptosis. We found that FOXM1 was overexpressed in ovarian granulosa cell (OGC) of patients with PCOS. Functionally, upregulation of FOXM1 promotes the proliferative ability of PCOS-OGC cells. As for mechanism, FOXM1 exerts its functions in PCOS-OGC cell through activation of the Wnt signaling pathway. More importantly, a novel FABP5 inhibitor, SBFI-26, was verified to downregulate the expression of FOXM1 to impede the proliferation of PCOS-OGC cells. In addition, SBFI-26 inactivates Wnt signaling pathway in PCOS-OGC cells. FABP5 inhibitor SBFI-26 regulates FOXM1 expression and Wnt signaling pathway in OGC of patients with PCOS, which might provide a new perspective into PCOS treatment.

Abstract
Bladder cancer is a very common malignancy. Although new treatment strategies have been developed, the identification of new therapeutic targets and reliable diagnostic/prognostic biomarkers for bladder cancer remains a priority. Generally, they are found among differentially expressed genes between patients and healthy subjects or among patients with different tumor stages. However, the classical approach includes processing these data taking into consideration only the expression of each single gene regardless of the expression of other genes. These complex gene interaction networks can be revealed by a recently developed systems biology approach called Weighted Gene Co-expression Network Analysis (WGCNA). It takes into account the expression of all genes assessed in an experiment in order to reveal the clusters of co-expressed genes (modules) that, very probably, are also co-regulated. If some genes are co-expressed in controls but not in pathological samples, it can be hypothesized that a regulatory mechanism was altered and that it could be the cause or the effect of the disease. Therefore, genes within these modules could play a role in cancer and thus be considered as potential therapeutic targets or diagnostic/prognostic biomarkers. Here, we have reviewed all the studies where WGCNA has been applied to gene expression data from bladder cancer patients. We have shown the importance of this new approach in identifying candidate biomarkers and therapeutic targets. They include both genes and miRNAs and some of them have already been identified in the literature to have a role in bladder cancer initiation, progression, metastasis, and patient survival.

Abstract
This case/control study is aimed at investigating the expression of CEP55, PLK1 and FOXM1 in bladder cancer tissues and comparing it with healthy tissue and their relationship with clinicopathological features of BC. Total RNA was extracted; then, gene expression was performed using real-time PCR relative to 18 s rRNA. 2-ΔΔCT method was used to calculate the relative expression of genes. A significant over expression of FOXM1, PLK1 and CEP55 was observed in tumor samples compared to adjacent and normal bladder tissues (all p = 0.001). Therefore, they may be supposed as potential candidate's biomarkers for early diagnosis and targets for cancer therapy.

Abstract
OBJECTIVE To investigate the role of forkhead box protein M1 (FOXM1) mRNA expression and its prognostic value in stage pT1 non-muscle-invasive bladder cancer (NMIBC). PATIENTS AND METHODS Clinical data and formalin-fixed paraffin-embedded tissues from transurethral resection of the bladder from patients with stage pT1 NMIBC, treated with an organ-preserving approach, were analysed retrospectively. Total RNA was isolated using commercial RNA extraction kits, and mRNA expression of FOXM1, MKI67, KRT20 and KRT5 was measured by single-step quantitative RT-PCR using RNA-specific TaqMan Assays. Statistical analysis was performed using Spearman's Rho, Wilcoxon or Kruskal-Wallis tests, Kaplan-Meier estimates of recurrence-free (RFS), progression-free (PFS) and cancer-specific survival (CSS) and Cox regression analysis. RESULTS Data from 296 patients (79.4% men, median age 72 years) were available for the final evaluation. Spearman correlation analysis showed that mRNA expression of FOXM1 was significantly correlated with MKI67 (ρ: 0.6530, P < 0.001) and with the luminal subtype, reflected by the positive correlation with KRT20 (ρ: 0.2113, P < 0.001). Furthermore, there was also a strong correlation of FOXM1 expression with adverse clinical and pathological variables, such as concomitant carcinoma in situ (P = 0.05), multifocal tumours (P = 0.005) and World Health Organization 1973 grade 3 disease (P < 0.001). Kaplan-Meier analysis showed overexpression of FOMX1 to be associated with worse PFS (P = 0.028) and worse CSS (P = 0.015). FOXM1 overexpression was also shown to be a predictive risk factor for CSS (hazard ratio 1.61 [1.13-2.34], L-R chi-squared: 7.19, P = 0.007). FOXM1 overexpression identified a subgroup of patients within the luminal subtype with worse RFS (P = 0.017), PFS (P < 0.001) and CSS (P = 0.015). Patients with low FOXM1 expression had better outcomes, irrespective of instillation therapy, whereas patients with high FOXM1 expression benefitted from intravesical chemotherapy with mitomycin C. CONCLUSION High FOXM1 expression was associated with adverse clinical and pathological features and worse outcomes, and predicted response to intravesical instillation therapy in patients with stage pT1 NMIBC.

Abstract
Forkhead box M1 (FOXM1) is a late cell cycle gene that plays a crucial role in carcinogenesis and chemotherapeutic drug resistance. In this study, the impact of FOXM1 expression on patient outcome was investigated for the first time in formalin fixed and paraffin embedded (FFPE) samples of chemotherapy naïve muscle-invasive bladder cancer (MIBC) patients. Expression analyses were performed on the Mannheim cohort (n=84) and validated on the independent Chungbuk cohort (n=61). In a Cox’ proportional hazards model, a distinct FOXM1 expression cut-off dividing both cohorts in a ‘high-risk’ and ‘low-risk’ group has been determined. Multivariate analyses showed that FOXM1 is an independent risk factor for outcome prediction superior to the TNM system. The FOXM1 ‘high-risk’ group had a 4- to 7-fold increased risk of death (p<0.03) and presented further an overexpression of MKI67. Recent studies showed that MIBCs can be subclassified in breast cancer-like subtypes: basal, luminal and p53-like. Here we demonstrated that FOXM1 was differentially expressed between MIBC subtypes concordant to its subtype specific expression in breast cancer. Since the proto-oncogene FOXM1 is known to play an important role in cisplatin resistance and to be a promising drug target, this study supports FOXM1 as a crucial biomarker in the personalization of MIBC therapy and urges prospective translational studies.

FoxM1 is an independent poor prognostic marker and therapeutic target for advanced Middle Eastern breast cancer. Oncotarget 2018; 9:17466-17482.

Abstract
Breast cancer (BC) is the most common cause of cancer-related death in females in Saudi Arabia. BC in Saudi women tend to behave more aggressively than breast cancer in the West. Therefore, identification of new molecular targets and treatment strategies are highly warranted to improve patient outcome. FoxM1 has been shown to play a critical role in pathogenesis of various malignancies. In this study, we explored the prevalence and clinical implication of FoxM1 overexpression in Saudi breast cancer. FoxM1 protein overexpression was seen in 79% (770/975) of BC tissues and was associated with aggressive clinical parameters such as younger age (< 30 yrs) (p = 0.0172), high grade (p < 0.0001), mucinous histology (p < 0.0001) and triple negative phenotype (p < 0.0001). Overexpression of FoxM1 was significantly associated with activated AKT (p < 0.0001), Ki67 expression (p < 0.0001), VEGF (p < 0.0001), MMP-9 (p < 0.0001), XIAP (p < 0.0001) and Bcl-xL (p = 0.0300). Importantly, FoxM1 overexpression is found to be an independent prognostic marker in multivariate analysis in advanced stage (Stage III and IV) breast cancer (p = 0.0298). In vitro data using BC cell lines showed that down-regulation of FoxM1 using specific inhibitor, thiostrepton or siRNA inhibited cell migration, invasion and angiogenesis. In addition, treatment of BC cell lines with thiostrepton resulted in inhibition of proliferation and induction of apoptosis in a dose-dependent manner. In vivo, thiostrepton treatment regressed MDA-MB-231 cells generated xenografts via down-regulation of FoxM1 and its downstream targets. Our results suggest that FoxM1 may be a potential therapeutic target for the treatment of aggressive breast cancers.

Abstract
Redox adaptation plays an important role in cancer cells drug resistance. The antioxidant response is principally mediated by the transcription factor Nrf2, that induces the transcriptional activation of several genes involved in GSH synthesis, chemoresistance, and cytoprotection. YAP is emerging as a key mediator of chemoresistance in a variety of cancers, but its role in controlling the antioxidant status of the cells is yet elusive. Here, we show that impairing YAP protein expression reduced GSH content and Nrf2 protein and mRNA expression in bladder cancer cells. Moreover, in YAP knocked down cells the expression of FOXM1, a transcription factor involved in Nrf2 transcription, was down-regulated and the silencing of FOXM1 reduced Nrf2 expression. On the other hand, the silencing of Nrf2, as well as the depletion of GSH by BSO treatment, inhibited YAP expression, suggesting that cross-talk exists between YAP and Nrf2 proteins. Importantly, we found that silencing either YAP or Nrf2 enhanced sensitivity of bladder cancer cells to cytotoxic agents and reduced their migration. Furthermore, the inhibition of both YAP and Nrf2 expressions significantly increased cytotoxic drug sensitivity and synergistically reduced the migration of chemoresistant bladder cancer cells. These findings provide a rationale for targeting these transcriptional regulators in patients with chemoresistant bladder cancer, expressing high YAP and bearing a proficient antioxidant system.

Abstract
Forkhead box protein M1(FoxM1) is a member of forkhead superfamily transcription factors. Emerging evidences have progressively contributed to our understanding on a central role of FoxM1 in human cancers. However, perspectives on the function of FoxM1 in breast cancer (BC) remain conflicting, and mostly were from basic research. Here, we explored the expression profile and prognostic values of FoxM1 based on analysis of pooled clinical datasets derived from online accessible databases, including ONCOMINE, Breast Cancer Gene-Expression Miner v4.0, and Kaplan-Meier plotter. It was found that, FoxM1 mRNA expression was significantly higher in breast tumor versus normal control. FoxM1expression profile presented a distinct pattern in different molecular subtypes of BC patients. Higher expression of FoxM1 was correlated to low mRNA expression of estrogen receptor 1 (ESR1), erb-B2 receptor tyrosine kinase 2 (ERBB2), and was inversely associated with the expression of classical luminal regulators forkhead box protein A1 (FoxA1) and GATA binding protein 3 (GATA3). Elevated FoxM1 expression predicted shorter distance metastasis free survival (DMFS) in BC patients, particularly with estrogen receptor (ER) positive and Luminal A, Luminal B subtypes of BC. More interestingly, elevated FoxM1 expression predicted poor survival in breast cancer patients, especially in the ER (+), progesterone receptor (PR) (+) subgroups and BC patients received adjuvant chemotherapy only or treated with tamoxifen only. These results implied that FoxM1 is an essential prognostic factor and promising candidate target in the treatment of breast cancer.

Abstract
BACKGROUND AND OBJECTIVE Muscle-invasive bladder cancers (MIBCs) are heterogeneous cancers and can be grouped into basal-like and luminal subtypes that are highly reminiscent of those found in breast cancer. Like basal-like breast cancers, basal-like MIBCs are associated with advanced stage and metastatic disease. However, the biological and clinical significance of molecular subtypes of MIBCs remain unclear. Therefore, we implemented a serious of bioinformatics methods to explore genetic similarities between bladder and breast cancers. METHODS AND RESULTS In the current study, by the application of multiple levels data analysis including random forest analysis, PPI and transcription factor regulation network construction, Gene Ontology (GO) and KEGG pathway enrichment analysis, we explored the genetics commonness between MIBC and breast cancers from the molecular heterogeneity based on the disease subtypes. CONCLUSIONS Our study identified some basal-related and luminal-related genes shared by two cancers. These studies can help shed light on the potential relationships between MIBC and breast cancer as a whole.

Abstract
Eukaryotic elongation factor 2 kinase (eEF2K), an emerging molecular target for cancer therapy, contributes to cancer proliferation, cell survival, tumorigenesis, and invasion, disease progression and drug resistance. Although eEF2K is highly up-regulated in various cancers, the mechanism of gene regulation has not been elucidated. In this study, we examined the role of Forkhead Box M1 (FOXM1) proto-oncogenic transcription factor in triple negative breast cancer (TNBC) cells and the regulation of eEF2K. We found that FOXM1 is highly upregulated in TNBC and its knockdown by RNA interference (siRNA) significantly inhibited eEF2K expression and suppressed cell proliferation, colony formation, migration, invasion and induced apoptotic cell death, recapitulating the effects of eEF2K inhibition. Knockdown of FOXM1 inhibited regulators of cell cycle, migration/invasion and survival, including cyclin D1, Src and MAPK-ERK signaling pathways, respectively. We also demonstrated that FOXM1 (1B and 1C isoforms) directly binds to and transcriptionally regulates eEF2K gene expression by chromatin immunoprecipitation (ChIP) and luciferase gene reporter assays. Furthermore, in vivo inhibition of FOXM1 by liposomal siRNA-nanoparticles suppressed growth of MDA-MB-231 TNBC tumor xenografts in orthotopic models. In conclusion, our study provides the first evidence about the transcriptional regulation of eEF2K in TNBC and the role of FOXM1 in mediating breast cancer cell proliferation, survival, migration/invasion, progression and tumorgenesis and highlighting the potential of FOXM1/eEF2K axis as a molecular target in breast and other cancers.

Abstract
The aim of the present study was to investigate the role of forkhead box M1 (FoxM1) in epithelial-mesenchymal transition (EMT) and metastasis in colorectal cancer (CRC). Immunohistochemical assays were performed to detect FoxM1 and epithelial (E-) cadherin protein expression in 92 CRC, 61 colonic adenoma and 32 wild-type colonic tissue samples. Quantitative polymerase chain reaction (qPCR) assays were performed to determine the expression levels of FoxM1 and E-cadherin mRNAs in 30 CRC and adjacent normal mucosal tissues. RNA interference was used to knock down endogenous FoxM1 expression in CRC cell lines, and the migratory and invasive capacity of the CRC cells was analyzed. The expression of FoxM1, E-cadherin and neuronal (N-) cadherin in the CRC cell lines was evaluated using qPCR and Western blot analysis. The relative expression levels of FoxM1 mRNA and protein were significantly increased in the CRC tissues compared with those in the colonic adenoma and wild-type mucosal tissue samples (P<0.01). In contrast, the relative expression levels of E-cadherin mRNA and protein were significantly decreased in the CRC tissues compared with in the colonic adenoma and normal mucosal tissues (P<0.01). FoxM1 overexpression and decreased E-cadherin expression were significantly associated with poor colonic tissue differentiation, lymph node metastasis and an advanced tumor-node-metastasis stage. Additionally, the increased expression of FoxM1 was associated with a decrease in E-cadherin expression (P<0.01). Furthermore, RNA interference-mediated FoxM1 knockdown significantly inhibited the proliferation, migration and invasion of CRC cells. Downregulation of FoxM1 expression significantly increased E-cadherin expression and decreased N-cadherin expression. The results of the present study suggest that FoxM1 overexpression in tumor tissues is significantly associated with metastasis in CRC through the induction of EMT.

Abstract
Genomic and transcriptional studies have identified discrete molecular subtypes of bladder cancer. These observations could be the starting point to identify new treatments. Several members of the forkhead box (FOX) superfamily of transcription factors have been found to be differentially expressed in the different bladder cancer subtypes. In addition, the FOXA protein family are key regulators of embryonic bladder development and patterning. Both experimental and clinical data support a role for FOXA1 and FOXA2 in urothelial carcinoma. FOXA1 is expressed in embryonic and adult urothelium and its expression is altered in urothelial carcinomas and across disparate molecular bladder cancer subtypes. FOXA2 is normally absent from the adult urothelium, but developmental studies identified FOXA2 as a marker of a transient urothelial progenitor cell population during bladder development. Studies also implicate FOXA2 in bladder cancer and several other FOX proteins might be involved in development and/or progression of this disease; for example, FOXA1 and FOXO3A have been associated with clinical patient outcomes. Future studies should investigate to what extent and by which mechanisms FOX proteins might be directly involved in bladder cancer pathogenesis and treatment responses.

Abstract
Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are heterogeneous tumors that need to be molecularly defined to obtain novel therapeutic options. Forkheadbox protein M1 (FOXM1) is a crucial transcription factor in neoplastic cells and has been associated with differentiation and proliferation. We found that FOXM1 is strongly associated with tumor differentiation and occurrence of metastases in gastrointestinal NENs. In vitro inhibition by the FOXM1 inhibitor siomycin A led to down-regulation of mitotic proteins and resulted in a strong inhibitory effect. Siomycin A decreased mitosis rate, induced apoptosis in GEP-NEN cell lines and exerts synergistic effects with chemotherapy. FOXM1 is associated with clinical outcome and FOXM1 inhibition impairs survival in vitro. We therefore propose FOXM1 as novel therapeutic target in GEP-NENs.

Abstract
Human embryonic stem cells (hESCs) exhibit unique cell cycle structure, self-renewal and pluripotency. The Forkhead box transcription factor M1 (FOXM1) is critically required for the maintenance of pluripotency in mouse embryonic stem cells and mouse embryonal carcinoma cells, but its role in hESCs remains unclear. Here, we show that FOXM1 expression was enriched in undifferentiated hESCs and was regulated in a cell cycle-dependent manner with peak levels detected at the G2/M phase. Expression of FOXM1 did not correlate with OCT4 and NANOG during in vitro differentiation of hESCs. Importantly, knockdown of FOXM1 expression led to aberrant cell cycle distribution with impairment in mitotic progression but showed no profound effect on the undifferentiated state. Interestingly, FOXM1 depletion sensitized hESCs to oxidative stress. Moreover, genome-wide analysis of FOXM1 targets by ChIP-seq identified genes important for M phase including CCNB1 and CDK1, which were subsequently confirmed by ChIP and RNA interference analyses. Further peak set comparison against a differentiating hESC line and a cancer cell line revealed a substantial difference in the genomic binding profile of FOXM1 in hESCs. Taken together, our findings provide the first evidence to support FOXM1 as an important regulator of cell cycle progression and defense against oxidative stress in hESCs.

Abstract
The regulation of entry into and progression through mitosis is important for cell proliferation. Polo-like kinase 1 (PLK1) is involved in multiple stages of mitosis. Forkhead box protein M1 (FOXM1) has multiple functions in tumorigenesis and, in elevated levels, is frequently associated with cancer progression. The present study reports that FOXM1, a substrate of PLK1, controls the transcription mechanism that mediates the PLK1-dependent regulation of the cell cycle. The present study investigated the expression of PLK1 and FOXM1 in the clear renal cell carcinoma 769-P and ACHN cell lines, and indicated that the expression of PLK1 and FOXM1 are correlated in human renal cell cancer cell lines and that the suppression of PLK1 may decrease the expression of FOXM1. The knockdown of FOXM1 or PLK1 in renal cell cancer cell lines caused cell cycle progression to be blocked. As a result, the present study indicated the involvement of FOXM1 in PLK1-regulated cell cycle progression.

Abstract
FOXM1, a member of the Forkhead transcriptional family, plays an important role in the EMT process, and transforming growth factor-β1 (TGF-β1) has been identified as the most potent factor that can independently induce EMT in various types of cancer cells. Here we examine the important role of FOXM1 in TGF-β1-induced EMT and investigate the mechanism underlying the relationship between TGF-β1 and FOXM1. Lentivirus-mediated transfection was used to stably upregulate the expression of FOXM1, and a small interfering RNA (siRNA) was introduced to silence the expression of FOXM1. Transwell and wound-healing assays were then performed to assess the invasion and motility potential of non-small cell lung cancer (NSCLC) cells. The NSCLC cell lines exhibited EMT characteristics, including an elongated fibroblastoid shape, induced expression of EMT marker proteins, and increased migratory and invasive potential after induction with TGF-β1. The overexpression of FOXM1 enhanced TGF-β1-induced EMT in NSCLC cells. Knockdown of FOXM1 reversed TGF-β1-induced EMT in NSCLC cell lines but had no effect on the phosphorylation level of ERK. Additionally, U0126, an ERK signaling inhibitor, exerted a reversible effect on TGF-β1-induced EMT and inhibited FOXM1 expression. FOXM1 regulated by the ERK pathway can mediate TGF-β1-induced EMT in NSCLC and is a potential target for the treatment of NSCLC.

Abstract
Although 3,3'-diindolylmethane (DIM) has been suggested to reduce the risk of colorectal cancer, the underlying biological mechanism is not clearly understood. In the present study, we investigated the effect of DIM on the migratory and invasive activities of the human colorectal cancer cell lines DLD-1 and HCT116. DIM significantly inhibited the migration and invasion of colorectal cancer cells as assessed by wound healing and Matrigel invasion assays. The migratory ability of the DLD-1 and HCT116 cells was significantly reduced by DIM at 24 and 48 h. DIM also significantly inhibited the invasion rate of the DLD-1 and HCT116 cells in a dose-dependent manner. The mRNA expression levels of urokinase type plasminogen activator (uPA) and matrix metalloprotease 9 (MMP9) were significantly attenuated, whereas expression of E-cadherin mRNA was significantly enhanced, following DIM treatment. DIM also decreased the protein levels of uPA and MMP9, yet significantly increased E-cadherin protein expression. In addition, DIM significantly reduced the mRNA and protein levels of FOXM1 in the DLD-1 and HCT116 cells. Our results suggest that DIM can influence the cell migratory and invasive properties of human colorectal cancer cells and may decrease the invasive capacity of colorectal cancer through downregulation of uPA and MMP9 mediated by suppression of the transcription factor FOXM1.

Abstract
Increasing evidence indicated that insulin-like growth factor binding protein 7 (IGFBP7) was regarded as a potential tumor suppressor in various human cancers, but its role in gastric cancer is still largely unknown. In the present study, we performed a retrospective study which includes 247 gastric cancer patients. Among them, the IGFBP7 expression was detected by qRT-PCR in 138 cases of gastric cancer and adjacent non-tumor tissues and was further correlated with the expression of p53, Ki-67, and the clinicopathologic features. The results indicated that both IGFBP7 mRNA and protein in gastric cancer tissues were significantly lower than those in the adjacent non-tumor tissues. Additionally, the expression of IGFBP7 was correlated with the depth of invasion, lymph node metastasis, and TNM stage. Interestingly, the expression of IGFBP7 was negatively associated with Ki-67 (r = -0.227, P < 0.001) but positively associated with p53 (r = 0.140, P = 0.028). Univariate analysis showed that low expression of IGFBP7 was associated with poor prognosis (P < 0.001), and multivariate analysis showed that IGFBP7 (HR = 1.87; 95 % CI 1.65-2.17), distant metastasis (HR = 2.68; 95 % CI 1.58-4.56), and tumor size (HR = 1.45; 95 % CI 0.90-2.32) were independent prognostic factors for gastric cancer patients. These results demonstrated that IGFBP7 was downregulated in gastric cancer, and its low expression was potentially correlated with increased cancer cell proliferation and could be used to predicate poor prognosis in these patients.

Abstract
Forkhead box M1 (FOXM1), a member of the Fox family of transcriptional factors, is considered to be an independent predictor of poor survival in many solid cancers. However, the underlying mechanism is not yet clear. The aim of the present study was to investigate the clinical significance of the correlation between FOXM1 and epithelial-mesenchymal transition (EMT) in non-small cell lung carcinoma and the possible mechanism responsible for FOXM1-induced EMT and metastasis. In the present study, expression levels of FOXM1 and EMT indicator proteins were determined by tissue microarray (TMA) and immunohistochemical staining, western blotting and reverse transcription-PCR (RT-PCR). Other cellular and molecular approaches including gene transfection, small interfering RNA (siRNA), and migration and invasion assays were utilized. Our results demonstrated that FOXM1 overexpression was statistically significantly associated with a higher TNM stage (p=0.036), lymph node metastasis (p=0.009) and a positive smoking history of the patients (p=0.044). Additionally, high expression of FOXM1 correlated with loss of E-cadherin expression (p<0.001) and anomalous immunopositivity of Vimentin (p=0.002). Moreover, patient survival analysis demonstrated that high expression of FOXM1 (p=0.043) and the presence of lymph node metastasis (p=0.042) were independent prognostic factors for non-small cell lung cancer (NSCLC). Furthermore, various in vitro experiments indicated that overexpression or knockdown of FOXM1 expression altered EMT through activation or inhibition of the AKT/p70S6K signaling pathway. Collectively, the results suggest that FOXM1 may be used as a prognostic indicator for patients with NSCLC and promotes metastasis by inducing EMT of lung cancer cells through activation of the AKT/p70S6K pathway. Therefore, we suggest that FOXM1 may be a potential target for lung cancer therapy.

Abstract
Recently, stathmin 1 has been proposed to function as an oncogene based on some relevant studies in multiple types of human cancers. However, the role of stathmin 1 in gastric cancer carcinogenesis has not been elucidated yet. The aim of this study was to investigate the expression of stathmin 1 as well as its association with overall survival of gastric cancer patients. The expression of stathmin 1 was detected by real-time quantitative reverse transcription polymerase chain reaction and Western blotting in gastric cancer and adjacent nontumor tissues. In addition, stathmin 1 expression was analyzed by immunohistochemistry in paraffin samples from 210 primary gastric cancer patients. The expression levels of stathmin 1 mRNA and protein in gastric cancer tissues were both significantly higher than those in adjacent nontumor tissues. In addition, the expression of stathmin 1 is correlated with Lauren's classification, depth of invasion, lymph node metastases, and tumor node metastasis (TNM) stage (all P < 0.05). Univariate analysis showed that high stathmin 1 expression was associated with poor prognosis in gastric cancer patients (P = 0.040). Multivariate analysis demonstrated that only lymph node metastasis and TNM stage were the independent prognostic indicators for gastric cancer. Stathmin 1 expression status is not an independent prognostic factor for patients with gastric cancer. Further subgroup analysis revealed that stathmin 1 expression was significantly correlated with prognosis in diffuse type gastric cancer. This research showed that the stathmin 1 overexpression might play an important role in the pathogenesis and subsequent progression of gastric cancer. Stathmin 1 could also be a potential therapeutic target in gastric cancer, especially for diffuse type gastric cancer.
