Fig. 4From: Celastrol induces cell cycle arrest by MicroRNA-21-mTOR-mediated inhibition p27 protein degradation in gastric cancerCelastrol inhibited mTOR activity through miR-21. Western blot showed that celastrol significantly decreased p-mTOR level in BGC-823and MGC-803 cells (a). mTOR and mTORC2 kinase assays revealed that miR-21 mimic reversed the decrease of mTOR (b) and mTORC2 (c) activity. **P < 0.01, indicate significant differences from the respective control groupsBack to article page
