Abstract:
Glioma is one of the most common types of malignant cancer and the significance of microRNAs (miRNAs) in cancer therapy has been demonstrated. In the current study, miR-490-3p expression was significantly downregulated in glioma tissue and cell lines. Overexpression of miR-490-3p inhibited glioma cell proliferation and migration in vitro. In addition, the high-mobility group AT-hook 2 (HMGA2) was identified as a candidate target gene of miR-490-3p. The current study demonstrated that miR-490-3p mimic could inhibit HMGA2 protein expression in glioma cells. In addition, correlation analysis demonstrated that miR-490-3p and HMGA2 expression was inversely correlated in glioma tissues. Furthermore, the inhibitory effect of miR-490-3p mimic on cell proliferation and migration was partially reversed by the overexpression of HMGA2. Taken together, these results suggest that miR-490-3p may have a tumor suppressive role in glioma and therefore miR-490-3p may be a new target for the treatment of glioma.

When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.

Gene expression is the process in which DNA directs the synthesis of functional products, that is, proteins. Cells can regulate gene expression at various stages. It allows organisms to generate different cell types and enables cells to adapt to internal and external factors.

A gene is a stretch of DNA that serves as the blueprint for functional RNAs and proteins. Since DNA is made up of nucleotides and proteins consist of amino...
