Proteoglycans in cancer

Moreover, GAS5 that upregulated or downregulated the expression of PDCD4 and PTEN was reversed by inhibiting or overexpressing miR-21 level in Bel-7402 and HCCLM3 cells.

GAS5 suppresses cancer proliferation by acting as a molecular sponge for miR-21, leading to the de-repression of phosphatase and tensin homologs (PTEN), the endogenous target of miR-21.

Furthermore, we found that miR-21 was involved in lncRNA COL1A2-AS1-induced expression of Smad7, by which COL1A2-AS1 acted as endogenous sponge to adsorb miR-21 and in turn regulated Smad7 and a cascade of molecular to play a protective role in hypertrophic scar.
