2019-08-29
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

A number of factors have been shown to remove blocking end groups in order to make the termini of DSBs ligatable. A common non-ligatable end is one that contains either a 3′ phosphate or 5′ hydroxyl. The polynucleotide kinase/phosphatase (PNKP) is the NHEJ processing enzyme responsible for removing

Introduction Abdominal aortic aneurysm (AAA) is a daily concern in vascular surgery, as successful treatment is exclusively achieved by open or endovascular repair. Its prevalence is 2–11% among male smokers, and rupture the major complication, is associated with unacceptably high morbidity and m

The potent MK-2048 kinase EE2 induced a decrease in CYP2C11 activity (reduction in 2α-OH and 16α-OH testosterone) and protein at the 200 ppb dose and in this respect was similar to nonylphenol and genistein. This result agrees qualitatively with the results of Hallstrom et al. (1996) who exposed mal

The importance of EBI2 for B cell function was first suggested by the dramatic upregulation of this receptor in EBV-transformed lrrk2 and and further inferred from its regulation in activated and GC B cells (Birkenbach et al., 1993, Glynne et al., 2000, Shaffer et al., 2000). An involvement of EBI2

Everolimus treatment showed an increase in the number of plaques and a reduction in plaque size, depending on concentration and treatment time (Fig. 1, Fig. 2). Everolimus-pretreated Bax channel blocker adsorbed less virus with more plaque formation in the initial phase of infection (Fig. 3). The a

2019-08-28
P. falciparum DHFR-TS is a particularly important enzyme, because it is from the protozoan species that is associated with most malaria infections. Since this enzyme is responsible for catalyzing sequential reactions in the thymidylate cycle, its inhibition slows malarial dTMP production and therefo

Numerous studies have pointed to the DGAT reaction being critical for TAG assembly and in several cases it has been shown to limit carbon flux from lipid precursors towards TAG accumulation [12]. Thus, in Brassica napus, the DGAT substrate, diacylglycerol (DAG), accumulates during periods of rapid l

2019-08-28
DNA methylation is a relatively stable but reversible epigenetic mechanism that can regulate gene expression, and occurs at the three different cytosine sequence contexts (CG, CHG, and CHH, where H is C, A, or T) in plants [15]. Many studies suggest that DNA methylation status of genes influence pla

Citrus [29], comprising some of the most widely cultivated fruit crops worldwide, has been consumed as a food and dietary supplement. According to traditional Chinese medicine, dry pericarp of Citrus, as a Chinese herbal remedy, is capable of regulating Qi and expelling phlegm, and has been used to

Emphysema is an important component of COPD, which is responsible for airflow limitation. In the present study, a significant airspace enlargement was observed 21 days after elastase administration. Interestingly, daily administration of olaparib provided greater protection against emphysema as comp

Our study showed that parental morphine exposure in the adulthood is associated with an increased tendency toward morphine consumption in F1 but not F2 male offspring. Thus, it seems that trans-generational effects of parental morphine consumption disappear in the second generation. In support of ou

Intriguingly, our laboratory has shown that the I638F kinase domain mutant, unlike the L63V and G505 mutants, is incapable of receptor autophosphorylation and activation of its downstream effector SHP-2 when exposed to collagen stimulation. These data indicate that I638F is a loss of function mutati
