Abstract Dysregulation of the Hippo pathway in liver results overgrowth and eventually tumorigenesis. To date, several upstream mechanisms have been identified that affect pathway, which ultimately regulate YAP, major downstream effector pathway. However, regulators remain poorly defined. Sphingosine-1-phosphate (S1P) is a bioactive sphingolipid metabolite has shown to stimulate hepatocellular carcinoma (HCC) cell proliferation, but whether involved S1P-stimulated HCC proliferation remains...

Cell‐fate determination is influenced by interactions between master transcription factors (TFs) and cis‐regulatory elements. Hepatocyte nuclear factor 4 alpha (HNF4A), a liver‐enriched TF, acts as controller in specification of hepatic progenitor cells regulating network TFs to control onset hepatocyte cell fate. Using analysis genome‐wide histone modifications, DNA methylation, hydroxymethylation mouse hepatocytes, we show that HNF4A occupies active enhancers hepatocytes essential for...

In ovarian cancer, it has been shown that E-cadherin is down-regulated by epidermal growth factor (EGF) receptor (EGFR) activation, and cells with low expression are particularly invasive. Although generally believed reactive oxygen species play important roles in intracellular signal transduction, the role of EGF-mediated reductions remains to be elucidated. this study, we show EGF treatment up-regulating its transcriptional repressors, Snail Slug, human cancer cells. Using...

In high-grade ovarian cancer cultures, it has been shown that epidermal growth factor (EGF) induces cell invasion by activating an epithelial-mesenchymal transition (EMT). However, the effect of EGF on serous borderline tumors (SBOT) and low-grade carcinomas (LGC) remains unknown. Here, we show receptor (EGFR) was expressed, treatment increased migration in two cultured SBOT lines, SBOT3.1 SV40 large T antigen-infected cells (SBOT4-LT), LGC MPSC1 LT/ST-immortalized (ILGC). induced...

Elevated expression of cyclooxygenase 2 (COX2 (PTGS2)) has been reported to occur in human ovarian cancer and be associated with poor prognosis. We have previously demonstrated that COX2-derived prostaglandin E2 (PGE2) promotes cell invasion. had also epidermal growth factor (EGF) induces invasion by downregulating the E-cadherin through various signaling pathways. However, it remains unclear whether COX2 PGE2 are involved EGF-induced downregulation cells. In this study, we showed EGF...

Does transforming growth factor-β1 (TGF-β1) up-regulate connexin43 (Cx43) to promote cell–cell communication in human granulosa cells? TGF-β1 up-regulates Cx43 and increases gap junction intercellular activities (GJIC) cells, this effect occurs via the activin receptor-like kinase (ALK)5-mediated Sma- Mad-related protein (SMAD)2/3-SMAD4-dependent pathway. its receptors are expressed follicular fluid contains protein. In junctions play an important role development of follicles oocytes. This...
