TWIST1 transcriptionally regulates glycolytic genes to promote the Warburg metabolism in pancreatic cancer.
In this study, we found that the highly conserved transcription factor, TWIST1, is a crucial regulator of aerobic glycolysis in PDAC. Genetic silencing of TWIST1 significantly inhibited the glycolytic phenotypes of PDAC cells as revealed by reduced glucose uptake, lactate production, and extracellular acidification rate, which can be restored by re-expression of siRNA-resistant TWIST1. Moreover, tamoxifen-inducible expression of TWIST1 promoted the Warburg metabolism of PDAC cells. Mechanistically, by luciferase reporter assay and chromatin immunoprecipitation experiment, we showed that TWIST1 can directly increase the exp...

Complement C5b-9 and Cancer: Mechanisms of Cell Damage, Cancer Counteractions, and Approaches for Intervention
In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...
