Employing an unspecific redox-sensitive dye that is in line with preceding findings [62, 63]. However, it remains to become elucidated, which reactive species of which origin contribute for the oxidation of intracellular CM-H2-DCF (after ester cleavage) because no reporter dyes that are accepted of getting in a position to distinguish amongst diverse intracellular ROS are commercially readily available. Intracellular compartmentalization Tirandamycin A Cancer increases complexity which is not addressed by the basic dye. A promising but demanding strategy within this regard is thiol switch dyes (HyPER) [64]. Subsequently, a fast however transient raise of total p53 expression accompanied by its nuclear accumulation was observed. Parallel towards the nuclear trafficking, serine phosphorylation (Ser15 and Ser37) indicated an activation of p53 through external stimuli, which has been described for UV light stimulation previously [65]. Reports also demonstrate that p53 serine 15/37 internet sites are phosphorylated by stressrelated c-Jun N-terminal kinase (Jnk) and mitogenactivated protein kinase p38 (p38) at the same time as many upstream kinases, especially ataxia telangiectasia mutated (ATM), ataxia telangiectasia and Rad3-related (ATR), and checkpoint kinase 1/2 (Chk1/2) [66]. Besides DNA harm transduction, ATM and ATR act as cellular redox sensor signals [679].

The key event inside the described pathways could be the recognition of plasma-generated reactive oxygen species (ROS) by certain ROS sensors in keratinocytes (e.g., transcription aspects p53 and Nrf2 and kinases ATM or Keap1). Plasma generates ROS which in turn activate and phosphorylate p53 by means of upstream kinases. Activation of p53 increases transcription of p53 targets (BAX, CDKN1A, and GADD45), which increases p53-dependent apoptosis and cell death. Increased expression and phosphorylation of heat shock protein HSP27 by p38 MAP kinase result in p53 binding. HSP27 protects HaCaT cells from plasma-induced apoptosis by enhanced transcription of p21 resulting in cell cycle arrest, DNA repair, and cell survival. Plasma-induced activation and phosphorylation of MAP kinases (e.g., signal transduction and transcription control) modulates the expression of genes and proteins associated with proliferation and cell survival by way of Erk1/2. Thus, p53 acts as an anti- and prooxidant.was straight activated immediately after exposure of cells to H2O2 with no the presence of DNA strand breaks [70]. Observations point towards the value of ATM in oxidative strain response regulation in addition to its DNA harm sensing [71]. In an ATM-deficient mice model, increased levels of ROS and signs of oxidative stress within the central nervous program.
