  2020-01-22

  

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  2020-01-22

  

  We propose two different pathways for the production of this species: either that described by Dooley [24], where the phenol ring is first activated by binding of its oxygen to copper, or one where a copper-peroxo species would directly react with an active site tyrosine residue (Scheme 1B). This se

  In 2015–2016, half a century after its first biochemical characterization as a template-independent polymerase, it was shown that TdT can, firstly, assemble a DNA synapsis by itself, optimally with one micro-homology base-pair between strands [] and secondly, perform a template-dependent nucleotid

  Instead of receptor interaction or GT activity, we focused on the CPD and autoprocessing. The CPDs from the 2 toxins are highly homologous: each cysteine protease targets an intramolecular substrate and mediates InsP6-induced autoprocessing to release the GTD into host cytosol.40, 41 However, TcdB i

  2020-01-21

  

  Oral antipsychotics are substrates of CYP450 enzymes, which are crucial to their metabolism and elimination (Fig. 1). The efficacy and toxicity of antipsychotic agents is affected by factors that induce or inhibit CYP450 expression and function, such as drug–drug interactions. Additionally, the mult

  Herein we report the expression of shrimp Cdk-2 in hepatopancreas, gills and muscle, finding higher expression in hepatopancreas and gills and lower expression in muscle. No significant changes due to hypoxia and hypoxia reoxygenation were detected on the expression of Cdk-2 in hepatopancreas and g

  2020-01-21

  

  Different types of environmentally induced antinociception have been reported in a wide range of species (e.g., Behbehani, 1995, Bolles and Fanselow, 1980, Harris, 1996, Millan, 2002, Rodgers, 1995). According to Bolles and Fanselow (1980), fear and pain are independent and competing motivational sy

  2020-01-21

  

  Nile tilapia (Oreochromis niloticus) is an important species farmed worldwide (Doan et al., 2018). Lipid-rich diets are commonly used in Nile tilapia aquaculture to reduce feed cost, but impair lipid homeostasis (Huang et al., 2016). Therefore, it is important to determine whether forskolin can stim

  Stable isotope studies, applied to skeletal remains of early Pacific populations, have shown a trend toward a horticultural diet with temporal variation in response to local environmental conditions (Field et al., 2009; Kinaston and Buckley, 2013; Valentin et al., 2010, Valentin et al., 2014; Kinast

  In the present study we investigated the effect of morphine withdrawal on G-protein coupling to opioid and ET receptors in neonatal rats. Morphine-induced G-protein activation was significantly higher in neonatal rats undergoing morphine withdrawal; suggesting enhanced coupling of the receptors to G

  Primary renal PNET was first reported by Seemayer et al in 1975. The possible etiology of rPNET is based on the theory of neural cell intussusception in the kidney during development that initiates the tumorigenesis. rPNET most commonly affects young adults, with a mean age of 30.4 years and male pr

  While showing that deletion of EP1 maintains femur bone volume fraction and trabecular bone parameters during aging, perhaps more importantly we have also demonstrated that increased initial BV/TV in EP1 is protective against OVX-induced bone loss. That is, while mice lose an approximately equal pe

  On the opposite side, sPLA2-X has also been implicated in the pathology of cancer [167,168]. Human sPLA2-X induces lipid droplet formation in Ras-driven MDA-MB-231 triple-negative breast cancer Adriamycin and promotes their survival during nutrient stress. It acts through the products of its enzyma

  The EGFR belongs to the ErbB family of receptor tyrosine kinases (RTKs), comprised of four members: EGFR (ErbB1, HER1), HER2 (ErbB2), HER3 (ErbB3) and HER4 (ErbB4) [24]. HER receptors are activated by a group of epidermal growth factor (EGF) ligands and undergo homo- or hetero-dimerization during th
