GL-V9 induce apoptosis of CML cells via MAPK signaling pathway.

ABSTRACT: GL-V9, a derivative of wogonin, has shown potent antitumor effects in various cancers, yet its impact on chronic myeloid leukemia (CML) remains unexplored. In this study, we found that GL-V9 significantly decreased the viability of CML cells. Annexin V/PI staining demonstrated that GL-V9 induced apoptosis in a concentration-dependent manner. The JC-1 assay indicated a significant reduction in mitochondrial membrane potential (ΔΨm) in cells treated with GL-V9. Additionally, GL-V9 altered reactive oxygen species (ROS) levels in CML cells. Through transcriptomic sequencing and Western blot analysis, we further revealed that GL-V9 activated the MAPK pathway. These results suggest that GL-V9 is a promising therapeutic candidate for CML.

Project description:ObjectiveTo evaluate the antitumor capability and to investigate the underlying molecular mechanism of paclitaxel.MethodsFirst, cck-8 and apoptosis assays were used to determine survival and apoptotic effects of HS 737.T cells under treatment of paclitaxel. Next, RNA-seq and bioinformatics were used to determine the differentially expressed genes and to analyze the pathway involved. Quantitative real-time polymerase chain reaction was used to verify the accuracy of some differentially expressed genes (DEG). ClueGO was used to decode and visualize functionally grouped GO terms of differentially expressed genes, and to map the DEG protein-protein interactions (PPI) network. Western blotting was used to check the expression of target genes, the cleavage of Caspase-3 and PARP1, and the phosphorylation level of p53. Finally, transcriptomics, bioinformatics, and RNAi were used to estimate the antitumor capability and to identify the underlying mechanisms of paclitaxel in GCTB.ResultsOur data revealed that paclitaxel had significant time-dependent effects on the viability and induced apoptosis of HS 737.T cells. RNA-seq and bioinformatics analysis showed that apoptosis, death receptor signaling pathway, TNF signaling pathway, and TP53 regulated transcription of cell death genes pathway were closely associated with paclitaxel in the treatment of GCTB. Western bolt results revealed that paclitaxel induced cleavage of Caspase-3 and PARP1, and increased the phosphorylation level of p53 in HS 737.T cells. RNAi results showed that the expression level of TP53INP1 was significantly decreased in HS737.T cells (the decrease was more than 70%). In addition, we found that the inhibitory ratios of paclitaxel on HS737.T cells deficient in TP53INP1 were less than in HS737.T cells with empty vector (19.88 and 40.60%, respectively). Hence, our data revealed that TP53INP1 regulated paclitaxel-driven apoptosis in HS737.T cells.ConclusionPaclitaxel can significantly repress cell proliferation and induce apoptosis of HS 737.T cells through activating Caspase-3, PARP1, p53, and TP53INP1. Paclitaxel may be an effective drug in the management of GCTB.
