  Drug resistance development often involves structurally un-related drugs and, specifically both conventional and targeted agents. IGROV-1/Pt1 DNA decontamination spray are characterized by resistance to cisplatin and reduced sensitivity to inhibitors of EGF-R and MEK, the up-stream activator of ERK1

  The embryological and physiological roles of ATX ATX is a vital enzyme that is needed for early embryological development. ATX knockout (KO) (ENPP2−/−) embryos die in utero on average at day 9.5 with vascular and neural tube defects [30], [73], [74], [75]. In these mice, malformations in the alla

  2025-02-21

  

  Elevated expression of Aurora-A and -B frequently detected in a wide variety of human cancers strongly indicate that high expression of these kinases play roles in the development of cancer associated phenotypes. While Aurora-A has been shown to function as an oncogene when over expressed in mammali

  The activity of an enzyme may be regulated allosterically as well as transcriptionally. We have consistently studied REMS deprivation (REMSD) associated NA mediated allosteric regulation of Na-K ATPase activity in neurons and glia in vivo and in vitro (Amar and Mallick, 2015; Amar et al., 2016; Bask

  2025-02-21

  

  Among the most important Ca regulatory mechanisms are the Plasma Membrane Calcium ATPase (PMCA) and Sarcoplasmic Reticulum Calcium ATPase (SERCA). These pumps belong to the family of P-ATPases, which share the formation of an acid-stable phosphorylated intermediate as part of their reaction cycle. P

  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/

  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

  PGR regulation of epithelium–stroma crosstalk is proven by numerous studies that utilize genetically engineered mouse models. Before embryo implantation, epithelial PGR mediates the progesterone signal to transcriptionally increase the Ihh levels 13, 15. Epithelial IHH then activates the stromal hed

  2025-02-21

  

  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

  Conclusions The present protocol for localizing or “spotting” the site of action of an antioxidant in a micro-heterogeneous medium is based on the differences in its reactivity vis-à-vis the series of amphiphobic TEMPO derivatives 1a–f.

  Concluding Remarks Despite major advances in the development of antibody and small-molecule tumor angiogenesis inhibitors, therapy resistance, both innate and acquired, continues to limit further survival improvements for patients with cancer.

  Recently, different kinds of Aβ aggregation inhibitors have been reported, including small molecules [8], peptides [9], and nanoparticles (NPs) [10]. The working mechanisms of the inhibitors are mostly to bind or adsorb Aβ molecules and to affect the conformational changes followed by blocking the a

  However, in recent years advanced experiments and findings are emerging to give us more detailed information on Aβ-membrane interactions. Several reviews have provided background on the fibrillation of Aβ and the Aβ-membrane interactions [[18], [19], [20], [21], [22]]. In this review, we mainly focu

  Concluding Remarks and Future Perspectives Herein, we have highlighted our current understanding of the role of the LKB1-AMPK pathway and its related kinases in β cell biology. β cell-specific genetic models have been particularly useful in delineating precise roles for individual family members
