CDK9 inhibition reduced necroptotic cell death. (A) THP-1 cells were pretreated with FVD to inhibit CDK9 for 2 hours, and then stimulated with P. gingivalis. Expression of lactate dehydrogenase in the cell supernatants were assessed by LDH assay at 4- and 8-hours post-infection to represent cell death. (B) Same treatment was performed on PBMCs, and the expression of lactate dehydrogenase were detected. (C) The RNA levels of THP-1 cells related to necroptosis including TRIF, cFLIPS, cFLIPL, caspase-8, RIPK1, RIPK3 and MLKL were detected by real-time PCR. (D) The translational level was further detected by western blot. The images were collected from different gels with the same amount of samples. (**p < 0.01; ***p < 0.001).
