The T allele of HIF-1α gene C1772T was significantly associated with increased cancer risk in three genetic models: TT+CT vs.CC (dominant model OR=1.23, 95%CI=1.03-1.47), TT vs. CT+CC (recessive model OR=2.51, 95%CI=1.54-4.09), TT vs. CC (homozygote comparison OR=2.02, 95%CI=1.21-3.39).In subgroup analysis, the frequency of the T variant was found to be significantly increased in cervical cancer, pancreatic cancer, head and neck cancer, renal cell carcinoma, Asian and female subgroups.
Mechanistically, our study demonstrated that LSD1 synergized with HIF1α (hypoxia inducible factor-1α) in maintaining glycolytic process, which fueled pancreatic cancer uncontrolled proliferation.
Protein-bound polysaccharide decreases invasiveness and proliferation in pancreatic cancer by inhibition of hedgehog signaling and HIF-1α pathways under hypoxia.
We hypothesized that curcumin and its analogues EF31 and UBS109 would disrupt angiogenesis in pancreatic cancer (PC) through modulation of HIF-1α and NF-κB.
In the present study, we investigated the effect of three DNA polymorphisms within the thymidylate synthase gene and two within hypoxia inducible factor-1α on the prognosis of pancreatic cancer.
These results suggest that rAAV-siHIF and L: -ascorbate can inhibit the growth of nude mice xenograft tumor and HIF-1alpha could be a target of pancreatic cancer genetic and pharmacological therapy.
siRNA targeting HIF-1alpha induces apoptosis of pancreatic cancer cells through NF-kappaB-independent and -dependent pathways under hypoxic conditions.
The aim of the study was to observe the effect of small interference RNA (siRNA) targeting hypoxia-inducible factor 1alpha (HIF-1alpha) combined L-ascorbate on proliferation, migration, and apoptosis of hypoxic MiaPaCa2 human pancreatic cancer cells.
Role of hypoxia inducible factor-1α in the regulation of the cancer-specific variant of organic anion transporting polypeptide 1B3 (OATP1B3), in colon and pancreatic cancer.
We conclude that HIF-1 is the regulatory link between tumor hypoxia and VEGF production in pancreatic cancer, thus establishing a biochemical pathway between tumor hypoxia and neoangiogenesis in this highly aggressive neoplasm.
These findings revealed the function of RGC-32 in hypoxia-induced EMT and may have identified a novel link between HIF-1α and EMT for pancreatic cancer therapy.
