    Journal: J Biochem; 2021 Jul 03; 169(5):535-542. PubMed ID: 33226411.
    Abstract:
    The present study aimed to investigate the function of long non-coding RNA HEIH in gastric carcinoma (GC). Adjacent normal tissues and GC tissues were obtained from 72 patients. Real-time quantitative polymerase chain reaction (RT-qPCR) was utilized to measure the expression of HEIH in cancer tissues and cells. Cell Counting Kit-8 and transwell assays were employed to evaluate cell proliferation, migration and invasion. An Annexin V-fluorescein-isothiocyanate (FITC)/propidium iodide (PI) Apoptosis Detection Kit was used to evaluate the apoptosis ratio. RT-qPCR was used to detect the expression level of miR-214-3p. The expression of HEIH in GC tissues was higher than in adjacent normal tissues. The expression of HEIH was upregulated in MKN-45, NCL-N87, KATO III cell lines compared within normal gastric epithelial cells. Knockdown of lncRNA HEIH significantly decreased the number of migrated and invaded cells. Additionally, downregulation of HEIH could increase GC cell apoptosis compared with the non-specific control (NC) group. We also proved that miR-214-3p was the direct target of lncRNA HEIH, and that overexpression of miR-214-3p could reverse the effects of HEIH. Silencing of HEIH could suppress Gastric Carcinoma cell proliferation, migration and invasion by inhibiting miR-214-3p. Thus, HEIH might represent a novel biomarker and therapeutic target.
