  2022-06-27

  

  The γ-secretase complex comprises four core subunits: presenilin (PS), nicastrin (NCT), anterior pharynx-defective 1 (Aph1), and presenilin enhancer 2 (Pen2) [7], [8]. PS is the catalytic subunit of γ-secretase, and many PS mutations associated with familial AD result in a high Aβ42/Aβ40 ratio [5].

  Experimental Results and discussion Conclusion In conclusion, four bisnaphthalimides have been investigated for their potential G-quadruplex binding. The compounds 3a, 3b and 5b display high affinity for telomeric and oncogenic G-quadruplexes. On the other hand, 5a only show high affinity f

  The highest metabolic stability observed for compound 4k (EC50=0.41μM corresponding to 218ng/mL) among the four selected frontrunner candidates was the principal decisive point in nominating this compounds for pharmacokinetic characterization in mice at the dosage of 10mg/kg (administered intravenou

  2022-06-27

  

  Akt/mTOR signaling pathway is a major negative regulator of autophagy, via modulating ULK1 complex. It is well established that Inhibition of mTOR by deprivation of nutrients or growth factors, led to dephosphorylation of ULK1, ULK2, and Atg13 in human cells, which is a key step for ULK1 complex ass

  Recent research has focused on identifying key agonists and receptors mediating nutrient-induced GLP-1 and insulin secretion. The long-chain fatty c16 synthesis receptor GPR40 is the most abundant GPCR expressed in islet β cells and is also expressed on intestinal L-cells, where it contributes to G

  In the current study, we report the properties of P. anserina mutants carrying mutations in a gene encoding the bi-functional enzyme 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase (PFK-2/FBPase-2). This enzyme catalyzes two opposite reactions (Pilkis et al., 1995, Rider et al., 2004): synthesi

  2022-06-27

  

  Syt1 itself does not catalyze lipid mixing and membrane fusion. Rather, the pairing of vesicular and target membrane SNAREs into complexes serves to pull bilayers together to drive fusion; Ca•syt1 accelerates these fusion reactions so that they occur on rapid timescales in a manner that is precisel

  To understand the structural basis for the mode of action of indole-based compounds the crystal structures of bound to both the wild type and A128T IN CCDs have been solved. The X-ray crystallography studies have revealed that binds at the IN dimer interface in the principal LEDGF/p75 binding pock

  Thus far, it is reported that the histone methyltransferase activity of SUV39H1 is regulated through some posttranslational modifications. For example, deacetylation of SUV39H1 at Lys-266 by SIRT1 deacetylase increases SUV39H1 activity [31], and methylation of SUV39H1 at Lys-105 and Lys-123 by SET7

  Cell-cell junction proteins were the first upstream modules to be characterized as contact sensors through the Hippo pathway. These junctions may be divided in 2 categories: adherens and epithelial polarity junctions. The establishment of intercellular contacts involves the cadherin proteins present

  Most studies of HIF-1α have focused on its transcriptional activity-dependent functions. However, our results indicate that the oxidative stress-related effects of mtHIF-1α occur independently of its translocation to the nucleus and do not require its transcriptional activity. In fact, several studi

  Based on our results, we propose three possible mechanisms of HER2 loss after trastuzumab-based therapy (Fig. 3). The first possibility is a result of the differential effects of treatments on clonal subsets. In breast cancer, such selective pressure has been suggested to preferentially eradicate HE

  Nevertheless, the frequency of CTCs was higher in patients with metastatic breast cancer, which is to be expected because cancer ionophore from the original clone that caused the metastasis probably had features favoring their spread throughout the body. When we take HER2+ CTC counts ≥ 3 as a “stron

  Curcumin is a major yellow pigment in turmeric ground rhizome of Curcuma longa Linn, which is used widely as a spice and coloring agent in several foods such as curry, mustard and potato chips as well as cosmetics and drugs (Okada et al., 2001, Joe et al., 2004).
