• The attachment of ubiquitin to RTKs

  2021-06-15

  

  The attachment of ubiquitin to RTKs, such as EGFR, mediates efficient delivery through the endosome-lysosome system for proteolysis. In this way, RTK degradation enables cessation of signal transduction. A recent siRNA screen identified a number of USPs that can significantly modulate EGFR levels an

  2021-06-15

  

  Although the amino Vialinin A sequences of CUL4A and CUL4B share 82% identity, the existing studies have shown that these two proteins do not have significant functional redundancy. Elevated expression of CUL4A has been observed in a variety of cancer cells, such as breast cancer, ovarian cancer, li

  2021-06-15

  

  More unusual modifications also regulate DUBs. Recent reports have illustrated how reactive oxygen species (ROS) can regulate DUB activity 87, 88, 89, 90. ROS can serve as potent signaling molecules by reacting with active site cysteines of tyrosine phosphatases and some cysteine peptidases to form

  2021-06-15

  

  Herein, the interactions of etamicastat, nepicastat and zamicastat with P-gp and BCRP were evaluated. Although recent investigations have been performed to assess the involvement of P-gp in the rho kinase inhibitor exposure of nepicastat and etamicastat (Loureiro et al., 2015), the contribution of

• Thymine glycol severely inhibits DNA

  2021-06-15

  

  Thymine glycol severely inhibits DNA synthesis by replicative DNA polymerases and requires the action of specialized DNA polymerases for translesion synthesis (e.g. Ref. [26]). Eukaryotic and archaeal RNAPs were shown to pause after nucleotide insertion opposite TG [27,28]. Surprisingly, we found th

  2021-06-15

  

  Except for S-adenosylmethionine (SAM, Fig. 1), sources of endogenous DNA alkylation are not well defined. Other possible sources include nitroso compounds related to the well known mutagen methylnitrosourea which are generated in vitro by nitrosation of cellular amines including amino acids, protein

  2021-06-15

  

  Thus RhoA-mediated inhibition of DGKθ is a well-characterized pathway, conserved from C. elegans to mammalian tissues, which enables G-protein coupled receptors to regulate the extent and kinetics of DAG-mediated signaling by fine tuning DGK enzymatic activity. Acknowledgments Introduction Ce

  Multivariate models take interactions between cytokines into account and were used to accurately distinguish samples from different time points in pregnancy. The distinction accuracy did not increase with increasing time between the gestational time points, indicating that the cytokine development d

  The evaluation of internal exposure in workers with omethoate is challenging. Unfortunately, OPs are metabolized and excreted quickly in the urine usually within 24–48 h of exposure, and the variation in metabolic rates exists. Many factors influence daily urinary output, such as salt intake, urea a

  Both progesterone and the calcium ionophore A23187 rely on the synthesis of cAMP by sAC to elicit exocytosis in human sperm (Fig. 2E-H and [8], [60]). We had reported earlier that digestion of endogenous cAMP with recombinant cAMP-specific phosphodiesterase 4D [9] or inhibition of its synthesis with

  2021-06-11

  

  In conclusion, our results provide a new mechanistic insight into the signaling pathways mediating TDCIPP-induced apoptosis in cultured neuronal cells. We showed that TDCIPP-induced neuronal cell cytotoxicity and death are mediated via the ER stress-regulated apoptotic pathway, wherein the induction

  2021-06-11

  

  The lack of effective strategies, aiming to directly increase the neuronal survival, is reflected by the fact that the only available therapeutic interventions are indirect. They consist of acute therapeutic interventions involving chemical and/or surgical removal of the thrombotic clot (Taqi et al.

  2021-06-11

  

  One of the hallmarks of the terminal stages of apoptosis is the fragmentation of chromosomal DNA that proceeds in a two-step manner: the DNA is initially cleaved into 50–300kb fragments and eventually into oligonucleosomal pieces [12], [13]. The two major apoptotic nucleases are DNA fragmentation fa
