Abstract
OBJECTIVE Signal transduction and transcriptional activator 5A (STAT5A), which has been reported to be frequently phosphorylated in tumors, plays pivotal roles in tumor progression. However, the role of STAT5A in gastric cancer (GC) progression and the downstream targets of STAT5A remain largely unknown. METHODS The expression of STAT5A and CD44 were assessed. GC cells were treated with altered STAT5A and CD44 to evaluate their biological functions. Nude mice were given injections of genetically manipulated GC cells and growth of xenograft tumors and metastases was measured. RESULTS The increased level of p-STAT5A is associated with tumor invasion and poor prognosis in GC. STAT5A promoted GC cell proliferation by upregulating CD44 expression. STAT5A directly binds to the CD44 promoter and promotes its transcription. CONCLUSIONS The STAT5A/CD44 pathway plays a critical role in GC progression, promising potential clinical applications for improving treatment of GC.

Abstract
KIF5B-RET gene rearrangement occurs in ~1% of lung adenocarcinomas. Recently, targeted agents that inhibit RET phosphorylation have been evaluated in several clinical studies; however, little is known about the role of this gene fusion in driving lung cancer. Immunohistochemistry was used to evaluate the expression of the FOXA2 protein in tumor tissues of patients with lung adenocarcinoma. KIF5B-RET fusion cells proliferated in a cohesive form and grew tightly packed with variable-sized colonies. The expression of RET and its downstream signaling molecules, including p-BRAF, p-ERK, and p-AKT, increased. In KIF5B-RET fusion cells, the intracellular expression of p-ERK was higher in the cytoplasm than in the nucleus. Two transcription factors, STAT5A and FOXA2, exhibiting significantly different expressions at the mRNA level, were finally selected. p-STAT5A was highly expressed in the nucleus and cytoplasm, whereas the expression of the FOXA2 protein was lower; however, it was much higher in the nucleus than in the cytoplasm. Compared with the expression of FOXA2 in the RET rearrangement-wild NSCLC (45.0%), high expression (3+) were observed in most RET rearrangement NSCLCs (94.4%). Meanwhile, KIF5B-RET fusion cells began to increase belatedly from day 7 and only doubled on day 9 in 2D cell culture. However, tumors in mice injected with KIF5B-RET fusion cells began to rapidly increase from day 26. In cell cycle analyses, the KIF5B-RET fusion cells in G0/G1 were increased on day 4 (50.3 ± 2.6%) compared with the empty cells (39.3 ± 5.2%; P = 0.096). Cyclin D1 and E2 expressions were reduced, whereas CDK2 expression slightly increased. pRb and p21 expression was diminished compared with the empty cells, TGF-β1 mRNA was highly expressed, and the proteins were accumulated mostly in the nucleus. Twist mRNA and protein expression was increased, whereas Snail mRNA and protein expression was decreased. Particularly, in KIF5B-RET fusion cells treated with FOXA2 siRNA, the expression of TGF-β 1 mRNA was remarkably reduced but Twist1 and Snail mRNA were increased. Our data suggest that cell proliferation and invasiveness in KIF5B-RET fusion cells are regulated by the upregulation of STAT5A and FOXA2 through the continuous activation of multiple RET downstream signal cascades, including the ERK and AKT signaling pathways. We found that TGF-β1 mRNA, where significant increments were observed in KIF5B-RET fusion cells, is regulated at the transcriptional level by FOXA2.

Abstract
Hepatocellular carcinoma (HCC) is one of the deadliest cancer types worldwide. The centromere proteins (CENPs) are critical for the mitosis-related protein complex and are involved in kinetochore assembly and spindle checkpoint signaling during mitosis. However, the clinical significance of CENPs in the recurrence and progression of HCC remains poorly understood. Here, we examined the expression of all CENPs and their association with recurrence and survival of HCC patients using the global gene expression profile dataset established in our laboratory. The effect of silencing CENPF on cell viability, migration, and epithelial-mesenchymal transition (EMT) were detected using CCK-8, transwell, and western blot, respectively. RT-qPCR and western blot were performed to confirm the silencing of CENPF and the relationship between STAT5A and CENPF, while tumorigenesis was tested using the HCC Huh7 xenograft mouse model. Most of the CENPs is overexpressed in HCC, and overexpression of CENPF was significantly associated with the poor survival of HCC patients. CENPF promoted HCC cell lines migration and EMT progression. Knockdown CENPF inhibited cell growth activity against human HCC cells in vitro and xenograft tumors in vivo. Bioinformatics analysis revealed that CENPF genes are enriched in the cell cycle. Silencing CENPF arrested cell cycle at the G2/M phase and inhibited Cyclin B1 and Cyclin E1 expressions. Meanwhile, silencing CENPF prohibited phosphorylation of ERK and the expression of NEK2. Additionally, we found that STAT5A down-regulated CENPF expression and inhibited cancer cell growth viability. In conclusion, our data suggested that CENPF could be potentially developed into a theranostic biomarker to tackle HCC progression.

Abstract
OBJECTIVE As an environmental endocrine disruptor, mono-2-ethylhexyl phthalate (MEHP) can interfere with liver metabolism and lead to liver diseases. We aimed to investigate the role of MEHP in liver fibrosis and its molecular mechanism. METHODS BRL-3A hepatocytes were exposed to MEHP (0, 10, 50, 100 and 200 μM) for 24 h. STAT5A gene was overexpressed by lentivirus transfection. The reactive oxygen species (ROS) was tested by the flow cytometer. The malondialdehyde (MDA), glutathione peroxidase (GSH-PX), aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels were detected by commercial kits. Real-Time PCR and Western blot were performed to test the relative mRNA and proteins levels, respectively. RESULTS MEHP exposure significantly induced oxidative damage in BRL-3A cells, which inhibited the expression of STAT5A and promoted the expression of fibrosis related proteins MMP2, MMP9, TIMP2 and CTGF. After over-expression of STAT5A gene in BRL-3A cells, the elevated expression levels of CTGF, MMP2, MMP9 and TIMP2 induced by MEHP exposure were significantly reversed. CONCLUSION This study demonstrated that MEHP exposure inhibited the expression of STAT5A by causing oxidative damage in BRL-3A hepatocytes, thus accelerating the expression of key molecules in fibrosis and promoting the occurrence of liver fibrosis.

Abstract
Chromodomain Y-like 2 (CDYL2), as a member of CDY family known to be involved in spermatogenesis, has been reported to participate in breast cancer development recently, but its exact biological role in hepatocellular carcinoma (HCC) remains unclear. Here, we observed that CDYL2 was down-regulated in human primary HCC tissues and the low levels of CDYL2 expression were correlated with poor survival. Gain- and loss-of-function experiments showed that CDYL2 inhibited the proliferation and metastasis of HCC cells in vitro and in vivo. Mechanistically, CDYL2 down-regulates solute carrier family 7 member 6 (SLC7A6) by decreasing the enrichment of H3K4me3 on the promoter region of SLC7A6. Additionally, we also found that signal transducer and activator of transcription 5A (STAT5A) could directly and positively regulate the expression of CDYL2. Thus, CDYL2 was regulated by STAT5A, and suppressed the amino acid transportation through down-regulation of SLC7A6, and then inhibits the mTORC1/S6K pathway, a master regulator of cell growth. Consistently, CDYL2 expression correlated significantly with STAT5A and SLC7A6 expression in HCC. Collectively, we propose a model for a STAT5A/CDYL2/SLC7A6 axis that provides novel insight into CDYL2, which may serve as a potential factor for predicting prognosis and a therapeutic target for HCC patients.

Abstract
MicroRNAs (miRNAs) are involved in various processes from the initiation and development of cancers, including chronic myeloid leukemia (CML). In this report, we aimed to investigate the roles of miR-23a in the regulation of imatinib mesylate (IM) sensitivity in CML cells and the possible mechanisms involved in this process. We demonstrated that the expression of miR-23a was markedly low in bone marrow mononuclear cells from patients in whom IM treatment had failed and imatinib-resistant K562/G01 cells when compared to patients with optimal responses and imatinib-sensitive K562 cells, respectively. Overexpression of miR-23a was shown to induce apoptosis of K562/G01 cells and sensitize these cells to imatinib treatment. With the aid of bioinformatics analysis, we revealed that CRYAB could be a potential downstream effector of miR-23a, contributing to miR-23a-mediated IM resistance. We also observed that the expression of CRYAB was inversely correlated with miR-23a expression in CML cell lines and patient samples. Importantly, chidamide upregulated miR-23a expression and reversed the IM resistance of CML cells. Together, these findings strongly suggest that miR-23a acts as a tumor suppressor by downregulating CRYAB expression. Restoration of miR-23a by chidamide may therefore have a therapeutic effect in controlling the sensitivity of CML cells to imatinib.

Abstract
BACKGROUND Numerous microRNAs (miRs), small RNAs that target several pathways, have been implicated in the development of Autosomal Dominant Polycystic Kidney Disease (ADPKD), which is the most common genetic cause of kidney failure. The hallmark of ADPKD is tissue overgrowth and hyperproliferation, eventually leading to kidney failure. SCOPE OF THE REVIEW Many miRs are dysregulated in disease, yet the intracellular pathways regulated by miRs are less well described in ADPKD. Here, I summarise all the differentially expressed miRs in ADPKD and highlight the top miR-regulated cellular driver of disease. MAJOR CONCLUSIONS Literature review has identified 53 abnormally expressed miRs in ADPKD. By performing bioinformatics analysis of their target genes I present 10 key intracellular pathways that drive ADPKD progression. The top key drivers are divided into three main areas: (i) hyperproliferation and the role of JAK/STAT and PI3K pathways (ii) DNA damage and (iii) inflammation and NFκB. GENERAL SIGNIFICANCE The description of the 10 top cellular drivers of ADPKD, derived by analysis of miR signatures, is of paramount importance in better understanding the key processes resulting in pathophysiological changes that underlie disease.
