1 METHODS: CCK-8 method was used to detect the viability of MM cell lines H929 and ARP-1 treated by different concentrations of celastrol, bortezomib, and their combination, and the synergistic effect was determined by Kim"s formula. celastrol actin related protein 1A Homo sapiens
2 RESULTS: Celastrol could significantly inhibit the proliferation of H929 and ARP-1 cells (r=0.9018, r=0.9244) and induce apoptosis in a time-dependent manner. celastrol actin related protein 1A Homo sapiens
3 Compared with the control group, celastrol could significantly up-regulate the expression of PARP and cleaved caspase-3 while down-regulate the expression of p-IRAK4, p-ERK, and p-p38 in H929 and ARP-1 cells. celastrol actin related protein 1A Homo sapiens
4 Celastrol and bortezomib alone inhibited the proliferation of H929 and ARP-1 cells. celastrol actin related protein 1A Homo sapiens
5 CONCLUSION: Celastrol can inhibit the proliferation and promote the apoptosis of H929 and ARP-1 cells, which may be related to inhibiting the phosphorylation of IRAK4 and blocking the activation of IRAK4/ERK/p38 signaling pathway. celastrol actin related protein 1A Homo sapiens
6 Celastrol combined with bortezomib has synergistic effect, which can more effectively inhibit the proliferation and induce apoptosis of H929 and ARP-1 cells. celastrol actin related protein 1A Homo sapiens
