  2024-12-26

  

  Here, we investigate the ATM to ATR switch in normal human fibroblasts (82-6 cells) after irradiation with γ-rays, or high LET 56Fe and 28Si and moderate LET 16O particles. Our data provide important evidence of LET dependence on the transition of ATM to ATR as well as end resection at the sites of

  2024-12-26

  

  Of the many different types of DNA lesions, DNA double strand breaks (DSBs) are amongst the most deleterious. It has been suggested that a single unrepaired DSB may be sufficient to induce cell death (Bennett et al., 1993), whereas misrepaired DSBs can result in loss of genetic information, potentia

  Fourth, non-canonical sites may be targeted. Classical benzodiazepines require the presence of a γ subunit for high-affinity binding, which limits their activity to a specific large pool of receptor isoforms, leaving other isoforms unaffected. In particular, δ subunit-containing receptors, as well a

  2024-12-26

  

  The presence of crown-like structures and inflammatory factors in the breast of obese patients is associated with considerable changes in intracellular signaling and a profound cellular dysfunction. Secreted pro-inflammatory factors can directly promote breast carcinogenesis as they have been report

  2024-12-25

  

  The 5′AMP-Activated Protein Kinase (AMPK) has evolved as an important cellular sensor of reduced energy status that can subsequently phosphorylate its target proteins, slowing the rates of key biosynthetic processes and promoting energy producing pathways; for these reasons AMPK has been proposed as

  APN accounts for 0.01% of total plasma proteins in humans; this proportion increases with age to a small extent (Barb et al., 2007). Normal APN levels in the circulation range 3–30μg/mL (Aprahamian and Sam, 2011). APN levels are lower in men than women due to the presence of testosterone and even mo

  Conclusions Several lines of evidence have been established, which support the adenosine kinase hypothesis of epileptogenesis, which is based on a sequence of events leading from acute Rac1 effector region injury to initial downregulation of ADK, rise in extracellular adenosine, changes in astro

  In the olfactory bulb, expression was especially prominent in the mitral cell layer from embryonic stages to adult tissues (Figs. 1D–G). By E14–E16, Ack1 signal was remarkably intense in the proliferative ventricular zone (Fig. 1D). From E18 to adult, expression was also observed in glomerular and g

  Qualitative inspection of the single-channel traces presented in both Figures 3 and 4 shows that within bursts of activity, βAnc-containing AChRs display a marked reduction in open probability. To quantify these differences in single-channel behavior, we performed dwell-time analysis under high-reso

  Several mechanisms have been suggested to account for the causal association of ICAM-1 induction and leukocyte adhesion with DR, including oxidative stress [16], NF-κB [17], PKC [18], and bioactive lipids [19]. Our previous studies highlighted the role of bioactive lipid metabolites derived from 12/

  The current findings proved that citral treatment induced mitochondrial-mediated apoptotic cell death in both HCT116 and HT29 through the p53 and ROS. As such, citral promoted apoptosis as evident by the externalization of PS and dissipation of Δψm at 24h of treatment in HCT116 and HT29 cells. These

  In addition to attracting immune cells to the site of injury, ROS also participate in proliferative responses during compensatory proliferation and regeneration. In Xenopus tadpoles, tail amputation induces sustained production of ROS over the span of regeneration, and decreasing ROS levels, especia
