  Research perspective In vitro and in vivo studies have demonstrated that increased LPA/ATX signaling contributes to cancer initiation and progression. Recent findings on the role of non-tumoral ATX in cancer progression and metastasis highlighted a new functional contribution for the microenviron

  Earlier studies showed that exposure of cells to IR caused ATM-dependent phosphorylation of 53BP1, as judged by electrophoretic mobility shift [24], [25], [26]. To date, the only known in vivo 53BP1 phosphorylation site(s) are Ser25 and possibly Ser29 [27]. In the course of our studies, we noticed t

  2024-08-20

  

  Calcineurin has been established to be a ubiquitous Ca2+-activated serine phosphatase in the nervous system (Pyrzynska et al., 2001). It has been reported that the activation of calcineurin protects aromatase from autophagy-mediated protein degradation, implying that calcineurin-dependent dephosphor

  Enhanced arginase activity and the resultant decreases in L-arginine levels can also impair T cell mediated immune function and allow tumor growth by limiting the supply of L-arginine needed for the formation of cytotoxic levels of NO by iNOS [10]. Increased arginase expression/activity may also lim

  Consistent with the above prediction, there are additional reports in which HMGA proteins have been demonstrated to facilitate recruitment of chromatin remodeling complexes to gene regulatory regions containing positioned nucleosomes during the transcriptional activation process. One particularly il

  Plant defensins (Vriens et al., 2014) and linear AMPs (Domingues et al., 2015, Liu et al., 2008) have been shown to present several modes of action. Among these different mechanisms, permeabilization of the fungal membrane has been described as a secondary effect of plant defensin action (Vriens et

  2024-08-20

  

  The reasons why antibiotic treatment may be detrimental are diverse. First, it may result in disruption of multifaceted microbe–microbe, as well as microbe–host, interactions that are key for the maintenance of homeostasis within this ecosystem. This can lead to the expansion of pathogenic microorg

  Steroidogenesis in the skin The synthesis of steroid hormones takes place in many tissues of which the adrenal glands, ovaries, testis, placenta and Sitagliptin phosphate monohydrate are considered to be classical steroidogenic organs. Nevertheless, skin constitutes an important peripheral stero

  Furthermore, stress hormones can indirectly induce DNA damage, for example by altering DNA repair and transcriptional regulation of the cell cycle. It has been found that stress hormones induce the up-regulation of checkpoint kinase 1 (Chk1) and checkpoint kinase 2 (Chk2) and proto-oncogene cell div

  Finasteride has been shown to be a mechanism-based inhibitor of 5AR-2 [9]. Finasteride acts as an alternate substrate for 5AR-2 and is initially bound in an extremely stable enzyme-bound NADP-dihydrofinasteride adduct which is ultimately processed to dihydrofinasteride. The NADP-dihydrofinasteride a

  Aurora kinases are a conserved family of serine/threonine kinases that are important for the transition through mitosis and amplification and overexpression of Aurora kinases have been implicated in ack1 inhibitor and transformation. Aurora B is located at the centromere and controls aspects of kin
