The aim of this study is to investigate the regulatory mechanism of leptin receptors (Ob-R) in pancreatic cancer. We found that the over-expression of hypoxia inducible factor (HIF-1)α and hypoxia up-regulated the expression of Ob-R in pancreatic cancer cells. When HIF-1α gene was silenced in vitro, the expression of Ob-R was significantly decreased. Xenograft mouse models showed that the inhibition...
This study aimed to investigate the interaction and regulatory mechanism of microRNA185 (miR185) and hypoxia-inducible factor-1 (HIF-1) in pancreatic cancer. The significance of miR185 on the clinicopathologic characteristics and prognosis was further explored. qRT-PCR and immunohistochemistry examined miR185 and HIF-1 expression of tumor tissues. Western blot analyzed HIF-1 protein expression. We...
