Abstract:
OBJECTIVE:To investigate the effects and underlying mechanism of miR-532-3p and resibufogenin (RES) by regulating Wnt/β-catenin signaling on diffuse Large B-cell lymphoma (DLBCL) cells proliferation.
METHODS:DLBCL tissues and adjacent normal tissues were collected from patients had been diagnosed with DLBCL at the First Hospital of Lanzhou University from October 2019 to October 2021. Four groups including mimics-NC, miR-532-3p mimics, RES control and RES treatment in SU-DHL-4 cells were designed. The expression level of miR-532-3p was detected by RT-qPCR. The protein content of β-catenin was detected by Western blot. MTT assay was used to detect the proliferation activity of SU-DHL-4 cells.
RESULTS:miR-532-3p expression was significantly decreased in DLBCL tissues compared with adjacent normal tissues (P<0.001). The miR-532-3p content in lymphoma cells was significantly lower than that in normal lymphocytes (P<0.001). After overexpression of miR-532-3p, the viability of SU-DHL 4 cells was significantly decreased (P<0.001), with a reduced expression of β-catenin (P<0.05). RES treatment inhibited the proliferation of SU-DHL-4 cells and decreased β-catenin expression in SU-DHL-4 cells compared with the control group.
CONCLUSION:Overexpression of miR-532-3p reduced Wnt/β-catenin signaling and inhibited the proliferation of lymphoma cells. Moreover, RES treatment inhibited lymphoma cells growth partially through Wnt/β-catenin signaling suppression.
