The present study demonstrated that ZNF16 (HZF1) plays an important role in erythroid and megakaryocytic differentiation of human haematopoietic stem/progenitor cells, identified and validated c-KIT as a direct target gene of ZNF16, and demonstrated that ZNF16 functions via its regulation on the c-Kit/c-Raf/MEK/ERK/c-Jun/HEY1/GATA1 cascade.

Hepatocellular carcinoma (HCC) is the third leading cause of cancer-associated mortality worldwide. Although the mechanisms of HCC progression are not well understood, recent studies demonstrated the potential contribution of uric acid transporter SLC2A9 to tumor suppression. However, the roles and underlying mechanisms are still unknown. We aimed to study the roles and mechanisms of SLC2A9 in HCC. The present study showed that SLC2A9 expression was decreased in human HCC tissues and cell lines. In addition, overexpression of SLC2A9 inhibited HCC cell proliferation. SCL2A9 induced HCC cell apoptosis by inhibiting the expression of caspase 3. Our study also revealed that upregulation of SLC2A9 reduced intracellular reactive oxygen species (ROS) accumulation. Furthermore, SLC2A9 increased the mRNA and protein expression of tumor suppressor p53 in HCC cells. Probenecid inhibits SLC2A9-mediated uric acid transport, which promotes cell proliferation, inhibits cell apoptosis, induces intracellular ROS, and decreases the expression of p53 in HCC cells. Therefore, the present study demonstrated that SLC2A9 may be a novel tumor suppressor gene and a potential therapeutic target in HCC.

Abstract RNA methylation can reverse the methylation modification at RNA level, which is a kind of extremely important epigenetic modification. YTHDF2, as a reader of m6A modification, the function and mechanisms of in epithelial ovarian cancer(EOC) have not been elucidated so far. In this study, we demonstrated that YTHDF2 was significantly upregulated in EOC tissues compared with normal ovarian tissues, further function studies confirmed that YTHDF2 significantly promoted the proliferation and migration of EOC cell lines, and reduced the global mRNA m6A levels. Next, we found that the expression levels of miR-145 and YTHDF2 were inversely correlated in ovarian cancer tissues and cells, and YTHDF2 is the direct target gene of miR-145. Interestingly, there was a crucial crosstalk between miR-145 and YTHDF2 via a double-negative feedback loop. Overexpression of YTHDF2 rescues miR-145-induced reduction of proliferation and migration in EOC cells. To conclude, YTHDF2 and miR-145, as two crucial m6A regulators, are involved in the progression of EOC by indirectly modulating m6A levels. In view of these promising results, YTHDF2 and miR-145 may provide new insights into the carcinogenesis and new potential therapeutic targets for EOC.
