ERRβ is present early in the developing placenta in a subset of wst-1 assay in extra-embryonic ectoderm destined to make up the chorion.19, 20 ERRβ is likely essential for reproduction. ERRβ expression is essential for the maintenance of pluripotency and self-renewal potential in mouse embryonic ste

An important focus of the present study has been the interaction of HUVECs with extracellular matrix in the regulation of angiogenesis. Matrigel is a gelatinous protein extract secreted by Engelbreth–Holm–Swarm mouse sarcoma cells, and is considered to be a good model of the extracellular matrix (Kl

In order to evaluate the in vivo pharmacology associated with EP receptor antagonism, we wished to discover antagonists presenting a higher degree of selectivity over the other prostanoid receptors. We also wanted to increase the brain–blood ratio since it is probable that centrally mediated EP agon

2021-01-14
An Ubl modification requires several steps that are catalyzed by three enzymes, referred to as E1 (activating enzyme), E2 (conjugation enzyme), and E3 (ligase). The SUMO E1 is a heterodimer of SAE1 and Uba2 (also known as SAE2). In brief, an Ubl is first activated by E1 through ATP hydrolysis and fo

Interestingly, our analyses of human PBMCs using a monoclonal antibody against EBI2 showed that the expression pattern of human EBI2 is largely overlapping with that in mice. Especially Th17 HC-030031 showed homogeneous high expression of EBI2 compared with Th1 cells, which contained a fraction of

Some family I DNA ligases can use dATP as nucleotide cofactor. For instance, human Berberine Sulfate I uses dATP with a catalytic efficiency that is only 36-fold lower in comparison to ATP [9]. EhDNAlig is unable to use dATP as a nucleotide cofactor, indicating a more constrained active site in com

Concluding remarks A crucial step in the microbial degradation of steroids is the 1(2)-dehydrogenation of the steroid nucleus by FAD-dependent Δ1-KSTDs. This step is required to initiate the opening of the steroid nucleus under both aerobic and anaerobic conditions. A large variety of steroid-deg

In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B. An

A major open question in the field of lipid mediators is the molecular nature of the PLA2 enzyme involved in the release of DHA and related omega-3 fatty acids from phospholipids as a first committed step for the generation of SPMs. Although by analogy with AA it is often assumed that cPLA2α may ser

PKA signalling in the nucleus was thought to be due to the translocation of the catalytic subunit upon activation from the KJ Pyr 9 to the nucleus via diffusion [72]. However, a new understanding has emerged, as both the regulatory and catalytic subunits have been identified in the nucleus and func

To study the effect of DDR inhibition by imatinib, nilotinib and dasatinib in a cellular environment we generated DDR1 and DDR2 expressing HEK293 cell lines by stable transfection. Of the five DDR1 splice variants we focused on the 1b variant whose over-expression has been associated with pulmonary

In our recent study, we established a procedure to examine the chromatin binding of XRCC4 using a biochemical fractionation analysis using a detergent Nonidet P-40 [22]. In this study, we investigated the role of LIG4 and its subdomains in the recruitment of XRCC4/LIG4 complex to chromatin. Mater

To understand more clearly how these activities are combined in the heterotrimeric enzyme and to understand more clearly how DNA alkylation might effect DNA helicase activity, we summarize the relevant features of the structure of RecBCD determined in the presence of DNA. The RecB and RecC subunits

Pulmonary fibroblasts can regulate the wound healing process by secreting and processing extracellular matrix (ECM), chemokines, and cytokines. However, persistent and atypical fibroblast proliferation can result in ECM accumulation and may trigger the onset or development of pulmonary fibrosis [[17
