  • Title: MiR-323a-3p suppressed the glycolysis of osteosarcoma via targeting LDHA.
    Author: Chen H, Gao S, Cheng C.
    Journal: Hum Cell; 2018 Oct; 31(4):300-309. PubMed ID: 30088225.
    Abstract:
    Accumulating evidence has demonstrated that there is critical involvement of miRNAs in the initiation and progression of cancers. Here, we showed that miR-323a-3p was significantly down-regulated in osteosarcoma (OS) tissues and cell lines. Overexpression of miR-323a-3p decreased the cell viability, colon formation and induced the apoptosis of OS cells. Using bioinformatics analysis, lactate dehydrogenase A (LDHA) was predicted as one of the down-steam targets of miR-323a-3p. Highly expressed miR-323a-3p significantly decreased both the mRNA and protein levels of LDHA. Inverse correlation between the expression of LDHA and miR-323a-3p was observed in OS tissues. Consistent with the function of LDHA in glycolysis of cancer cells, overexpression of miR-323a-3p attenuated the lactate production of OS cells. These results demonstrated that miR-323a-3p suppressed the growth of OS cells via targeting LDHA and inhibited the glycolysis of OS. This study provides insight into the molecular mechanism of miR-323a-3p in regulating OS.
