  Although TP53 status has been shown to play a role in ATR inhibition and platinum resistance [7], [27], [38], in inhibition of ATM and sensitivity to IR [39], and in the activation of Chk1 and Chk2 [3], [4], ATM and ATR signaling can occur through the p38MAPK/MK2 pathway in p53-deficient CAY10499 sa

  2024-10-24

  

  From an historical perspective, ligands for GPCRs (adrenaline, serotonin, Demethoxycurcumin or morphine, to name a few) have been identified before their receptor counterparts, at a time when the concept of receptor itself was controversial [15]. Although many cognate receptors for endogenous ligand

  Aromatase: the key enzyme for estrogen formation in adipose tissue Estrogens are synthesized from androgens by aromatase, a member of the cytochrome P450 superfamily, which is the rate-limiting enzyme in estrogen biosynthesis (Santen et al, 2009, Simpson et al, 1994). At the cellular level, aroma

  2024-10-24

  

  The PDZ domains of DLG interact with tumor suppressor proteins, APC and PTEN, as well as with several viral oncoproteins such as the E6 protein present in oncogenic human papillomavirus (reviewed in [177]). It has been reported that overexpression of DLG in fibroblasts impairs the events in the G0/G

  Introduction It has long been recognized that angiogenesis is critical to the growth, progression, and metastasis of many solid tumor types [1], and thus, drugs targeting the angiogenic pathway have been a topic of clinical investigation in the oncology community for many years. Angiogenesis is reg

  While there is structural information on the core of the amyloid fibril, less is known about oligomer structure. There is evidence that the C-terminal of Aβ may form beta barrels in some oligomer species (Tay et al., 2013, Do et al., 2016), or may exist as loosely aggregated strands in other oligome

  We designed SSOs that block APP exon 17 splicing and induce the production of an alternatively spliced APP mRNA lacking exon 17 (APPΔex17). APPΔex17 mRNA encodes an APP protein isoform that lacks 49 193 2 including the γ-secretase cleavage sites that give rise to the toxic, AD-associated Aβ42 pepti

  Previous reports indicate that the expression of AChRs and their clustering on myotubes are critical factors required to induce contacts on muscle fibers in a natural biological system [14], [15], [16], [17], [18], [19]. For instance, in NMJ development in the mouse, AChRs are pre-patterned at sites

  Based on these findings, the time point for manipulating autophagy may also determine its role, whereby autophagy induction performed before ischemia could play a protective role but have an opposite effect once ischemia/reperfusion has occurred. This hypothesis is further supported by the protectiv

  A disruption of lung barrier function caused by PM2.5 has been observed in our experiments; however the underlying mechanism has not been investigated. Zhao et al. (2018) reported that PM2.5 down-regulated the expression levels of tight junction (TJ) proteins and resulted in nasal epithelial barrier
