Abstract

MiR-30a-5p, a member of the microRNA-30 family (miR-30), is known to function as a tumor suppressor in several different cancers. However, the expression levels, biological function, and underlying mechanisms of miR-30a-5p in renal cell carcinoma (RCC) remain unclear. Glucose-regulated protein78 (GRP78) is a common cancer biomarker and promotes the growth and survival of cancer cells. The expression of GRP78 has been reported to be modulated by miR-30a in neurons. In this study, the expression profile of miR-30a-5p in clear cell renal cell carcinoma (ccRCC) and its effect on ccRCC through regulating GRP78 expression was investigated. MiR-30a-5p expression was analyzed using bioinformatic software on open microarray datasets from the Cancer Genome Atlas (TCGA) and Gene Expression Omnibus (GEO), and confirmed by quantitative RT-PCR (qRT-PCR) in ccRCC cell lines. Cell proliferation was investigated using CCK-8 and cell count assays. Western blotting, immunohistochemistry, luciferase reporter assays, and flow cytometry were employed to investigate the mechanisms of the effect of miR-30a-5p on ccRCC Results: MiR-30a-5p was down-regulated in ccRCC and related to the clinicopathological factors and prognosis of ccRCC. MiR-30a-5p was f...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis

Adenocarcinoma, Clear Cell

Clear Cell Adenocarcinoma is a tumor that arises in the female genital tract and is characterized by cells that appear clear under the microscope. Discover the latest research here.

Apoptosis in Cancer

Apoptosis is an important mechanism in cancer. By evading apoptosis, tumors can continue to grow without regulation and metastasize systemically. Many therapies are evaluating the use of pro-apoptotic activation to eliminate cancer growth. Here is the latest research on apoptosis in cancer.
