  Introduction The carnitine/choline acyltransferase family is a family of enzymes that play diverse roles, ranging from (the regulation of) Acetaminophen and fuel metabolism in mitochondria and peroxisomes to the generation of the neurotransmitter acetylcholine. In mammals, this family consists of s

  Outcome of COX-2 overexpression Although a causal role for COX-2 has been proposed, mechanisms by which COX-2 function contributes to the pathogenesis of hyperplastic disease are not well defined. To examine if there is any correlation between COX-2 and p53 protein levels, Kumagai et al. [15] rec

  Several models show the MAPK pathway involving p38 as the ApoBrdU DNA Fragmentation Assay Kit synthesis pathway in pro-inflammatory responses, with the ERK pathway involvement primarily devoted to cell growth and differentiation events (Lai et al., 2001, Widmann et al., 1999). The results of the cu

  We then analyzed Ki-67 proliferation index as a categorical variable by using 15%, essentially the median Ki-67 value in the entire study group (see above), to delineate low and high proliferation subgroups. By Fisher\'s exact test, both the type 1 versus non-type 1 EWS-FLI1 comparison (P = 0.047; T

  2020-05-14

  

  Primases are classified into two major groups: first, the DnaG primases, found in bacteria and bacteriophages, and second, the archaeoeukaryotic primases. Remarkably, bacterial and archaeoeukaryotic primases have no structural similarity and, presumably, evolved independently (Leipe et al., 1999). T

  Possibly there are similarities among euphorb plant species but extraction of the Sulindac sulfide present in the microsomal fraction is needed for testing their preferences for substrates. Although R. communis, E. lathyris and E. lagascae belong to the same family, the DGAT activity of their micro

  Nicotine is the main psychoactive component of tobacco that causes addiction. Besides the regulation of the stress responses, CRF has been implicated in nicotine addiction based on several lines of evidence (Bruijnzeel and Gold, 2005, Sarnyai et al., 2001). First, acute administration of nicotine, l

  Acknowledgements Introduction α-L-Rhamnosidases (EC 3.2.1.40) are glycosyl hydrolases (GHs) that cleave terminal α-l-rhamnose from a large number of natural products [1]. The action of α-L-rhamnosidases (α-RHAs) has been reported, among others, on different complex substrates such as heteropol

  Potential break-through technology poised to overcome these above-mentioned limitations is that of the “substrate mediated enzyme prodrug therapy”, SMEPT (Fig. 1). Learning from the previously established enzyme prodrug therapies (EPT) and specifically the antibody-directed EPT (ADEPT) [12], develop

  In this study we generated mice in which the native Bcl6 locus was engineered to produce a form of Bcl6 containing a mutant RD2 domain that disrupts its repressor function. We found that RD2 domain is essential for pre-GC B cell differentiation and clustering into nascent GC within follicles, in par

  2020-05-14

  

  In all available E2:E3 structures, the RING-type domain binds the E2 on a surface that is remote from the active site Cys (and therefore from the ubiquitin thioester) (Fig. 2). The non-contiguous E3-binding and active sites on the E2 imply that the role played by a RING to facilitate ubiquitin trans

  The yeast Rad6p (radiation sensitive 6, also called Ubc2) E2 ubiquitin-conjugating enzyme is a member of the highly conserved UBC proteins in eukaryotes (Xu et al., 2009). Rad6p is involved in several cellular processes, including DNA repair, transcriptional activation and silencing, histone ubiquit

  Here, we describe a novel series of arylazoderivatives developed from CAN508, one of the first known selective CDK9 inhibitors. We focused on modification of both ends of parental molecule, CAN508, in order to improve cytotoxicity and CDK activity. We therefore analyzed how changes in molecules will
