Abstract

The inhibitory effect of microRNA (miR)‑325 in multiple different types of cancer cell has been identified; however, its biological function in T cell acute lymphoblastic leukemia (T‑ALL) remains unknown. Moreover, Bcl‑2‑associated athanogene (BAG)2 is highly expressed in a various types of tumors and is regarded as an anti‑apoptotic gene. In the present study, the roles of miR‑325 and BAG2 in a T‑ALL cell line (Jurkat cells) were investigated. BAG2 and miR‑325 expression levels in clinical blood samples from healthy donors and pediatric patients with T‑ALL, as well as in T‑ALL cell lines was detected using western blot analysis and/or reverse transcription‑quantitative PCR. Dual‑luciferase reporter gene assays and TargetScan were used to evaluate the interaction between BAG2 and miR‑325. Small interfering RNA technology was applied to knockdown BAG2 expression in Jurkat cells. The effects of miR‑325 mimic and BAG2 downregulation on the proliferation and apoptosis were assessed by an MTT assay, flow cytometry and western blot analysis. The results revealed that the expression of miR‑325 was downregulated in blood samples from pediatric patients and in T‑ALL cell lines, and its expression was lowest in Jurkat cells. The expression levels of BAG2 exhibited the opposite results. The knockdown of BAG2 markedly induced the apoptosis and inhibited the proliferation of Jurkat cells. In addition, the overexpression of miR‑325 significantly inhibited the growth and promoted the apoptosis of Jurkat cells, with these effects being eliminated by BAG2 overexpression. In conclusion, the findings of the present study demonstrated that miR‑325 directly targets the BAG2 gene and that the introduction of miR‑325 can accelerate apoptosis and suppress the proliferation of Jurkat cells by silencing BAG2 expression.
