Mammalian cells that sustain genotoxic as well as oncogenic insults must involve defensive mechanisms that either arrest cell cycle progression or trigger an apoptotic program. However, to discriminate between physiological and potentially harmful states, the defensive mechanisms must be finely tuned. A complex and non-redundant molecular pathways have been described to enable cells to respond to a plethora of stressful stimuli. Thus, a number of molecular responders are called in action when cells are subjected to scenarios that negatively affect their normal homeostasis. Because the RNA polymerase II transcription is the endpoint of signal transduction pathways that mediate the cellular response to different stimuli, it is not of a surprise that changes in the phosphorylatation state of the largest subunit of RNA polymerase II (RNAPII) mediated by the CDK9/CyclinT (P-TEFb) complex, occur in response to genotoxic insults. Accordingly, changes in the dynamic state, activity and stoichiometry of the P-TEFb complex are the hallmark of the cellular defensive mechanisms in response to a variety of genotoxic insults. Thus, P-TEFb is not only involved in controlling cell-cycle progression as specific co-factor of important cell growth controlling genes such as Myc and p53, but it also functions as an early sensor of genotoxic insults. The study on P-TEFb and the signaling pathways that regulate its activity is the major topic of research.
