  2020-10-10

  

  Here we uncover a highly diverse superfamily of self-replicating MGEs, dubbed pipolins, which are present in three major bacterial phyla, as well as in mitochondria, and encode divergent PolB carrying TPR1 and TPR2 subdomains. Biochemical characterization of a representative enzyme encoded by a pipo

  2020-10-10

  

  The related catalytic regions of the human DNA ligases contain three domains, a DNA binding domain (DBD), a nucleotidyl transferase domain (NTase) and an oligonucleotide/oligosaccharide-fold binding domain (OBD) (Ellenberger and Tomkinson, 2008). Similar to DNA ligase I, the DNA ligase III polypep

  The possibility that a carboxyl group attached to the or position of an -arylaminomethylenemalonate ester would lead to increased selectivity for DHODH has been tested and found not to be the case. Indeed, reduced selectivity compared with the corresponding ester is observed and is attributed to a

  2020-10-10

  

  Collagen X is a homotrimeric molecule of three α1(X) chains (Mr 59 kDa) comprising a 45 kDa triple-helical domain flanked by an N-terminal (NC2) and a larger C-terminal (NC1) non-collagenous domains (Shen, 2005). In the hypertrophic ECM, collagen X most likely forms an extended hexagonal network, as

  Conclusions This study showed that in EOC cells, tyrosine kinase receptor DDR1 was expressed mainly in EOC EX527 with an Epithelial phenotype. The repressed expression of DDR1 in EOC cells with Mesenchymal phenotype could be due to the higher CpG methylation levels observed at the promoter of thi

  2020-10-10

  

  In summary, the reduction of one or more pro-inflammatory cytokines, such as TNF-α, IL-1β, IL-6, IL-8 was observed in almost all the monoterpenes studied. Increased levels of the anti-inflammatory cytokine IL-10 was shown to play a prominent function in the anti-inflammatory effect of monoterpenes,

  2020-10-10

  

  p27kip1 is a member of the cyclin-dependent kinase (CDK) inhibitor family that acts as a potent tumor suppressor in a variety of human cancers and negatively regulates the transition of cells from the G1 to S phase of the cell cycle, protects against inflammatory injury and promotes epithelial diffe

  Several studies have already shown that mPR activation can significantly reduce intracellular cAMP levels in different kind of cells, such as GT1-7 neuronal cells [32], MDA-MB-468 breast cancer cells [55] and primary vascular endothelial cells [56]. The experiments performed with PTXa and 8-Br-cAMP

  Here, we examined whether Intracellular ER may mediate Cd-induced ovarian cancer proliferation. To determine this relationship, we used ICI 182,780 as a general inhibitor of ERα and ERβ. The results suggest a metalloestrogenic effect of Cd in ovarian cancer cell lines. Inconsistency with our results

  Introduction Psoriasis is a chronic, recurrent and inflammatory skin disease, and it is characterized by erythema, skin hyperplasia, scales, and hyperproliferation of keratinocyte [1]. It is reported that the psoriasis occurrences are about 3% worldwide [2], but the number varies depending on ethni

  As for the molecular mechanism, Ferguson BD suggested that EphB4/EphrinB2 stimulation induced topoisomerase I activity in small cell lung cancer cell lines. Treatment of AUY-922 with EphrinB2/Fc induced topoisomerase activity as assessed by DNA relaxation in cells with high EphB4 expression levels,
