DNA PK Jackson is activated by DNA
2021-03-13

DNA-PK (Jackson, 1997) is activated by DNA double-stranded breaks (DSBs). It is a trimeric complex composed of the catalytic subunit, DNA-PKcs, and the Ku70/80 heterodimer. DNA-PK mediates non-homologous end joining (NHEJ), which joins programmed DSBs created during V(D)J recombination and class swi

Introduction Although not fully understood, the molecular toxicology of sulfur mustard (bis(2-chloroethyl)sulfide, SM; CAS–Nr. 505-60-2), an alkylating warfare agent, has been attributed to DNA alkylation [1], [2], [3]. The same principle holds true for other alkylating compounds such as nitrogen

2021-03-13

The second DDR1-binding partner identified here, Shp-2, which was not found in the two-hybrid screen but using a bioinformatics approach, is also a mediator of cell migration. Since Shp-2 has two SH2 domains, as well as phosphotyrosine phosphatase enzymatic activity and two C-terminal tyrosines targ

p16 is a tumor-suppressor gene that inhibits cyclin-dependent kinase 4 and 6 activities and arrests the Oltipraz in the G1 phase. Aberrant methylation and mutation of p16/MTS1 in OSCC of patients was found in our previous study. Moreover, the frequency of hypermethylation of p16 from the present st

Studies also provide evidence that cytokines such as TGF-β, a TH3-type cytokine, may also play a role in airway remodeling. Data obtained by Cohen et al suggest that TGF-β1 can induce human BSMC proliferation by increasing the expression of IGFBP-3. Hence, the mitogenic action of TGF-β1 could be rel

2021-03-12

From the general synthetic route, we first synthesized a directed set of analogues of general formula , keeping the synthesis simple by using a symmetrical pyrazole (R=R=Me). The SAR of a set of 30 compounds in the GTPγS binding assay turned out to be quite tight: only 4 (13%) compounds showed moder

The use of inhibitors clearly has its caveats and the field should come to a consensus on etomoxir concentration to maximally block LC-FAO while minimalizing off-target effects. The current papers convincingly show that 200 μM is too high, but it should be noted that 3 μM does not fully suppress LC-

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

2021-03-12

The rate of protein degradation is often affected by N-starvation [12], therefore, we examined the influence of N-starvation against the appearance of CEPs. N-starved cucumber cotyledons contained less amounts of protein and Rubisco, but the temporal changes in protein and Rubisco contents were simi

Collagen type 1 is the most abundant extracellular matrix (ECM) protein found in vertebrates. Collagen exerts its role as a load bearing structure and regulator of cell function, only after it has assembled into fibrils., The equilibrium between the synthesis and degradation of collagen fibrils and

2021-03-12

The concept of GPCRs and EGFRs existing as heteromers is consistent with previous studies. Co-immunoprecipitation studies have shown that agonist stimulation (both AngII and EGF) promotes a multi-protein complex containing the AT1R and EGFR, however these endpoint assays were not in live cells or in

All components of the UPP were predicted to be susceptible to oxidative stress due to the cysteine residues in their active sites [36]. Curcusone D inhibits DUBs but has no significant effect on the action of E1, E2s, E3s, or the proteasome, which indicates that the targets of the ROS induced by cur

To overcome problems with the biochemical reconstitution of these heterodimeric cytokines fusion strategies linking both subunits together have been proposed inspired by the “hyper-IL-6” [28]. Much like fusing a protein to a solubility enhancing protein such as MBP or SUMO, fusing two subunits of a

2021-03-11

Almost 75% of drugs in the market undergo deactivation though oxidation, reduction or hydrolysis by cytochrome P450 (CYP) enzymes, and then, either directly or by facilitated excretion from the body (Guengerich, 2008). The CYP3A subfamily is of particular interest because of its broad substrate spec
