  APC/C Uses a Dynamic Cullin–RING Mechanism to Elongate Polyubiquitin Chains Human APC/C generates Lys11-linked poly-Ub chains through an entirely different mechanism, via the distinctive E2 enzyme, UBE2S 30, 31, 32. Although APC2 and APC11 are necessary and sufficient to activate UBE2S, the mecha

  2019-07-18

  

  Dysfunction of the ubiquitin-proteasome system causes abnormal organelle morphology and impairs sperm formation and maturation steps resulting in male infertility [[7], [8], [9]]; this indicates that ubiquitination is essential for spermatogenesis and sperm function during fertilization. β-catenin i

  2019-07-18

  

  The expression of cytokine-inducible genes is mediated by a number of components within the cell. It has been shown that Jak2 and the Ras/Raf/MAP kinase signaling cascades are required for the expression of DUB-1[9], [29]. However, the enhancer domain of DUB-1 lacks a consensus sequence for Stat bin

  2019-07-18

  

  A limitation of this study is the between-study heterogeneity of the datasets analyzed. To address this heterogeneity, we used a random-effects model in our analysis. Also, only 2 of the databases provided information on sex, and as a result, the sex-specific analyses were performed with a smaller c

  Steroid biosynthesis Steroid hormone metabolism in breast cancer Conclusion Steroid hormones elicit their biological actions primarily by binding to steroid receptors such as the ER, AR, PR and GR. Although classical breast cancer diagnostic panels assess the expression of the ER and PR, as

  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

  The third challenge is to understand the mechanisms of drug resistance. There are several different mechanisms of ES tumor to develop drug resistance. First, cancer stem cells are capable of proliferate and generate tumor cells with new sets of mutations which may harbor different protein targets [1

  Ample evidence has shown that ET-1 system plays a pivotal role in the development of cardiovascular anomalies and pharmacological inhibition of ETA prevents the development of cardiac hypertrophy [[37], [38], [39]].

  2019-07-17

  

  In contrast, T-bet downregulated the expression of Tfh functional molecules, CD40L, ICOS, and IL-21; accordingly, T-bet overexpression abrogated the helper function of IL-12-stimulated CD4+ T cells. Thus, T-bet seems more involved in the downregulation of the helper functions than in the differentia

  2019-07-17

  

  Multi-subunit RING-type E3 ligases are exemplified by the CULLIN-RING-ligase (CRL) and the anaphase-promoting complex/cyclosome (APC/C) [19]. CRLs constitute the biggest family of other multi-component E3 ligases. These consist of a cullin scaffold protein (CULLIN 1, 2, 3, 4A, 4B, 5, 7), a substrate

  2019-07-17

  

  DNA methylation is associated with transcriptional silencing of tumor suppressors or other genes important for normal cellular function and plays an important role in the development of cancer and other diseases (such as breast and colorectal cancers) [19]. DNA methyltransferases (MTases) are a fam

  Although PQQ has nutritional importance and pharmacological effects in higher organisms, including humans [15], until recently, there was no clear evidence for the use of PQQ as a co-factor in a eukaryotic enzyme. This review presents a novel eukaryotic PQQ-dependent quinohemoprotein recently discov
