Abstract
Background: Acute lymphoblastic leukemia (ALL) is the most common leukemia in children, which is associated with a high relapse rate despite prevalent therapies. Ganoderic acid-A (GAA) is one of the bioactive compounds of Ganoderma lucidum, which possesses potential antileukemic properties. Objective: This study aimed to investigate the effect of the GAA extract on the expression of microRNA and the apoptosis induction in the cell line.
Methods: In this case-control study, NALM-6 Cells were treated with the GAA extract and L-asparaginase separately. The cell viability and apoptosis rates were examined using MTT and flow cytometry, respectively. Moreover, the effect of the GAA on the expression of miR-125b and miR-365a-3p, in comparison to L-asparaginase, was studied using RT-PCR.
Result: The GAA extract inhibited the cell growth in a dose- and time-dependent manner. Moreover, the GAA extract significantly induced apoptosis compared to L-asparaginase (P=0.0021 vs. P=0.0112). The results showed that the treatment of Nalm-6 cells with GAA significantly reduced the expression of miR-125b (P< 0.0001) and miR-365a-3p (P= 0.0001). Furthermore, it was demonstrated that the downregulation of miR-125b and miR-365a-3p was surprisingly higher in the GA-treated Nalm-6 cells than in L-asparaginase-treated Nalm-6 cells.
Conclusion: According to the findings, the GAA extract has antileukemic effects and can be used as a promising agent with fewer side effects in all treatments.
