RESUMO

Aim To explore the effeet of the extract of Celastrus orbiculatus extract on the proliferation anrl ap- optosis of multiple myeloma eells (U-1996) and its molecular mechanism.Methods The U-1996 eells were divided into normal control ( NC ) group, the southern snake vine extraet group, si-NC group, si- LINC00472 group, pcDNA-NC group, pcDNA- LINC00472 group, southern snake vine extraet + si-NC group,and southern snake vine extraet + si-LINC00472 group.Heal-time quantitative PCR was used to deteet LINC00472 expression, CCK-8 and flow cytometry to deteet eell proliferation and apoptosis, Western blot to deteet the expression levels of phosphorvlated phos- phatidvlinositol-3 -hydroxykinase (p-PI3K) and phos- phorylated protein kinase B ( p-Akt).Results After treated with Celastrus orbieulatus extract, the viability of U-1996 eells and the expression of p-PI3K and p- Akt were significantly reduced, the apoptotie rate and the expression of LINC0047 were significantly raised ( P < 0.05 ).After inhibiting the expression of LINC00472, the viability of U-1996 eells and the ex¬pression of p-PBK and p-Akt significantly inereased, the apoptotie rate and the expression of LINC0047 sig¬nifieantly deereased ( P <0.05 ).After overexpression of LINC00472, the viability of U-1996 eells and the ex¬pression of p-PI3K and p-Akt were signifieantly re- dueed, the apoptotie rate and the expression of LINC0047 significantly inereased ( P <0.05 ).Inhibi¬ting the expression of LINC0047 can reverse the effects of Celastrus orbiculatus extract on proliferation , apopto- sis and PI3K/AKT signaling pathway of U-1996 cells (P < 0.05 ).Conclusions Celastrus orbiculatus ex¬tract can inhibit the proliferation of multiple myeloma cells and induce apoptosis through up-regulating LINC00472 to inhibit PI3K/Akt signaling pathway.
