Abstract:
Objective To investigate the effect of curcumin regulating miR-142-5p targeting pleckstrin homology domain containing family A member 3(PLEKHA3)on proliferation,migration and apoptosis of adrenocortical carcinoma cells.Methods Adrenal cortical cancer cells were divided into NC group(normal culture),NC+60 μmol·L-1 curcumin(60 μmol·L-1 curcumin),NC+60 μmol·L-1curcumin+miR-142-5p group(60 μmol·L-1 curcumin and transfected with miR-142-5p mimic),NC+60 μmol·L-1 curcumin+miR-142-5p+PLEKHA3 group(60 μmol·L-1 curcumin and transfected with miR-142-5p mimic+PLEKHA3).Cell proliferation and migration abilities were detected by cell counting kit-8(CCK-8)and Transwell assays.Expression levels of apoptosis-related proteins were detected by Western blotting.At the animal level,a nude mouse model of human adrenal cortical tumor SW-13 cell transplantation was established and divided into control group and 15,30,45,60 μmol·L-1curcumin groups to verify the anti-adrenal cortical carcinoma effect of curcumin in vivo.Results The cell migration numbers in NC group,NC+60 μmol·L-1 curcumin group,NC+60 μmol·L-1+miR-142-5p group and NC+60 μmol·L-1+miR-142-5p+PLEKHA3 group were 135.76±17.42,37.11±10.08,98.31±14.88 and 24.39±5.28;the apoptosis rates were(3.27±0.11)％,(68.80±4.64)％,(25.47±2.39)％and(78.29±5.47)％;the protein expression levels of B-cell lymphoma 2(Bel-2)were 1.00±0.13,0.59±0.11,0.97±0.09 and 0.31±0.06;the protein expression levels of Bel-2 associated X protein were 1.00±0.08,1.38±0.11,0.69±0.05 and 1.93±0.18;there were statistically significant differences between NC group and NC+60 μmol·L-1 group(P＜0.05,P＜0.01).At the animal level,the volumes of the xenograft tumors in control group and 15,30,45 and 60 μmol·L-1 curcumin groups were(1 653.02±435.93),(1 148.77±327.18),(1 054.21±286.06),(996.89±257.62)and(670.64±157.32)mm3;the weights of the xenograft tumors were(1.00±0.17),(0.82±0.09),(0.76±0.12),(0.68±0.13)and(0.44±0.11)g,there were statistically significant differences between 15,30,45 and 60 μmol·L-1curcumin groups and control group(P＜0.05,P＜0.01).Conclusion Curcumin exerts anti-adrenal cortical cancer effects both in vitro and in vivo,may inhibit the proliferation and migration of adrenal cortical cancer cells and promote their apoptosis by regulating the miR-142-5p/PLEKHA3 signaling pathway.This provides a new potential target for the treatment of adrenal cortical cancer.
