Using an unspecific redox-sensitive dye which can be in line with preceding findings [62, 63]. However, it remains to be elucidated, which reactive species of which origin contribute for the oxidation of intracellular AMAS custom synthesis CM-H2-DCF (after ester cleavage) considering the fact that no reporter dyes that are accepted of becoming in a position to distinguish involving distinctive intracellular ROS are commercially offered. Intracellular compartmentalization increases complexity that is not addressed by the simple dye. A promising but demanding approach in this regard is thiol switch dyes (HyPER) [64]. Subsequently, a speedy but transient raise of total p53 expression accompanied by its nuclear accumulation was observed. Parallel for the nuclear trafficking, serine phosphorylation (Ser15 and Ser37) indicated an activation of p53 by means of external stimuli, which has been described for UV light stimulation previously [65]. Reports also demonstrate that p53 serine 15/37 web sites are phosphorylated by stressrelated c-Jun N-terminal kinase (Jnk) and mitogenactivated protein kinase p38 (p38) too as many upstream kinases, particularly ataxia telangiectasia mutated (ATM), ataxia telangiectasia and Rad3-related (ATR), and checkpoint kinase 1/2 (Chk1/2) [66]. In addition to DNA damage transduction, ATM and ATR act as cellular redox sensor signals [679].

The main occasion within the described pathways is the recognition of plasma-generated reactive oxygen species (ROS) by distinct ROS sensors in keratinocytes (e.g., transcription components p53 and Nrf2 and kinases ATM or Keap1). Plasma generates ROS which in turn activate and phosphorylate p53 via upstream kinases. Activation of p53 increases transcription of p53 targets (BAX, CDKN1A, and GADD45), which increases p53-dependent apoptosis and cell death. Improved expression and phosphorylation of heat shock protein HSP27 by p38 MAP kinase outcome in p53 binding. HSP27 protects HaCaT cells from plasma-induced apoptosis by increased 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 handle) modulates the expression of genes and proteins associated with proliferation and cell survival by means of Erk1/2. As a result, p53 acts as an anti- and prooxidant.was directly activated just after exposure of cells to H2O2 without the presence of DNA strand breaks [70]. Observations point towards the value of ATM in oxidative tension response regulation as well as its DNA damage sensing [71]. In an ATM-deficient mice model, improved levels of ROS and signs of oxidative pressure inside the central nervous technique.
