ABSTRACT
OBJECTIVE@#To observe the effects of down-regulation of long non-coding RNA HOX antisense intergenic RNA myeloid 1 (LncRNA-HOTAIRM1) to the proliferation and apoptosis of Jurkat in human leukemia T lymphocytes, and explore its mechanism.@*METHODS@#Jurkat cells were cultured in vitro and randomly divided into control group, HOTAIRM1 siRNA-NC group and HOTAIRM1 siRNA group; the expressions of LncRNA-HOTAIRM1 mRNA, KIT receptor tyrosine kinase (KIT) mRNA and serine threonine kinase (AKT) mRNA in Jurkat cells were detected by real-time fluorescence quantification (RT-qPCR); the proliferation of Jurkat cells in each groups was detected by CCK-8 method; the apoptosis of Jurkat cells in each groups was detected by Annexin V-FITC/PI double staining; the expressions of KIT, AKT, p-KIT, p-AKT, B-lymphoma-2 gene (BCL-2) and Caspase-3 were detected by Western blot.@*RESULTS@#Compared with the cells in the control group and HOTAIRM1 siRNA-NC group, the expression level of LncRNA-HOTAIRM1 mRNA, cell survival rate, expression levels of KIT mRNA, AKT mRNA, p-KIT, p-AKT and BCL-2 proteins in Jurkat cells in HOTAIRM1 siRNA group were significantly lower (P<0.05), while the expression level of Cleared Caspase-3 protein and Jurkat cell apoptosis rate were significantly higher (P<0.05).@*CONCLUSION@#LncRNA-HOTAIRM1 may inhibit Jurkat cell proliferation and induce apoptosis through KIT/AKT signaling pathway.
