2020-10-23

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

2020-10-22

In addition to Gα coupling, it is important to consider that the transition from goal-directed to habitual drug taking also relies on striatal D2R-A2AR heterodimers. Following cocaine self-administration, D2R-A2AR density is increased in the NAc, leading to greater antagonism of the inhibitory (anti

O-GlcNAcase Human OGA is a multidomain protein with an N-terminal domain similar to glycoside hydrolase family 84 (GH84) enzymes, a stalk domain, a C-terminal pseudo histone acetyltransferase (HAT) domain, and several low-complexity regions (Figure 1f) [43]. A splice variant that lacks the HAT do

Enzyme activity loss during the hydrolysis process has traditionally been associated with thermal, mechanical, and/or chemical mechanisms (Okino et al., 2013, Ye et al., 2012, Zhang et al., 2010). Due to the recent discovery of enzyme activity loss due to interaction with substrate, it is important

Materials and methods Results Discussion Fluoride has multiple effects that contribute to caries prevention. S. mutans is 20- to 40-fold more sensitive to NaF than Lactobacillus casei and seven-fold more sensitive than some species of Actinomyces[10]. There are some specific metabolic effec

Several studies on the collagen receptor DDR1 have revealed a defined collagen signaling pathway that causes cell scattering and cadherin switching. As mentioned earlier, DDR understand on collagens are distinct from integrin binding sites; therefore, the same collagen protein can bind to DDR and i

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

2020-10-22

This pathway appears to have importance in epilepsy. DGKε(−/−) mice had significantly fewer motor seizure and epileptic events compared with DGKε(+/+) mice [18]. This could be explained by the fact that in the knockout mice a greater fraction of the SAG would be converted to 2-AG. 2-AG itself is kno

Perturbation in the cytokine network is correlated with disruption of growth hormone and glucocorticoid (GC) homeostasis (Thissen and Verniers, 1997; Sahid El-Radhi et al., 2000; Waxman and Holloway, 2009; Zhao et al., 2014), with important physiological consequences because cytokines affect the reg

Conclusions Introduction Today – just as for the past 50 years – the most commonly used repellent in the world is DEET (Fradin, 1998; Pickett et al., 2008). The active ingredient, N,N-Diethyl-m-toluamide, is an oily synthetic substance applied topically to the skin in order to alter the host f

Here, we report for the first time that EphB4 contains two NLS sequences and localises to the nucleus. This is mediated via an importin-α pathway and we show that EphB4 could potentially have a direct role in gene regulation. These data provide new insight into Eph receptor localisation and action a

Plasminogen is composed of five N-terminal kringle domains and a C-terminal serine protease domain. The kringle domains have an affinity to lysine and binding of plasminogen with its receptors is dependent on its lysine interacting kringle domains [10], [28]. In the current report, we show that enol

Human neutrophil elastase (HNE) is a serine protease central to the pathology in a wide range of diseases including chronic wounds, cystic fibrosis, and acute respiratory distress syndrome (Owen, 2008). Although neutrophil proteases are necessary for completion of wound healing, HNE is secreted in h

A factor that complicates the use of human liver Sulindac receptor is one of variability, which arises in part because many of the human liver samples available for research show various stages of a variety of disease states (steatosis (fatty liver), cirrhosis, carcinogenesis in adjacent tissue), a
