Novel evidence for oncogenic piRNA-823 as a promising prognostic biomarker and a potential therapeutic target in colorectal cancer.

ABSTRACT: piRNA-823 as a member of the piRNA family is reported to promote tumour cell proliferation in multiple myeloma and hepatocellular cancer. However, few studies on the function of piRNA-823 in colorectal cancer (CRC). Our present study data showed that piRNA-823 plays an oncogene role in CRC cells. Inhibition of piRNA-823 can significantly inhibit the proliferation, invasion and apoptosis resistance of CRC cells. Mechanism studies have shown that piRNA-823 inhibits the ubiquitination of hypoxia-inducible factor-1 alpha (HIF-1α) by up-regulating the expression of Glucose-6-phosphate dehydrogenase (G6PD) and ultimately up-regulates the glucose consumption of carcinoma cells and inhibits the content of intracellular reactive oxygen species (ROS). Therefore, we speculate piRNA-823 promotes the p
