  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

  2021-04-19

  

  Another example of negative regulation is the inhibition of the yeast endosome-associated DUB Doa4 by Rfu1 (free ubiquitin chains 1). In a yeast genetics screen, deletion of Rfu1 was serendipitously found to alter global ubiquitin levels [69]. DUBs can regulate these levels by liberating conjugated

  Here we investigate in more detail how Dot1 function contributes to the regulation of DNA damage tolerance. We find that Dot1 modulates the response to the alkylating agent MMS through its catalytic activity on H3K79. In fact, progressively reduced levels of H3K79 tri-methylation result in gradually

  Introduction Collagen deposition is a common feature found in cancerous tissues and fibrotic organs/lesions. It is now well accepted that collagen deposition is not just a consequence of disease, but that it can also trigger a vicious cycle. Both chemical and physical signals elicited from collagen

  Khan et al. investigatedAnomalin 44, a pyranocoumarin constituent of S. divaricata, which exhibits potent anti-inflammatory activity. The anomalin 44 dose-dependently inhibited inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) mRNA and protein expression in LPS-stimulated RAW 264.7

  The nuclear receptor (NR) superfamily of ligand regulated transcription factors has proven to be a rich source of targets for the development of therapeutics for a wide range of human diseases. The NR3B subfamily known as the estrogen-related receptor (ERRα[NR3B1], ERRβ[NR3B2] and ERRγ[NR3B3]) regul

  The work described by Dong, Groves, and co-workers (11) tested the hypothesis that neural stem cell development is sensitive to the clustering and mechanical state of the EphB4:ephrin-B2 receptor-ligand complex. They show that the quality of ephrin-B2-ligand signaling depends on its biophysical stat

  EBV Infection Epstein–Barr virus (EBV, human herpesvirus 4) was discovered 50 years ago, when Epstein, Achong, and Barr used electron microscopy to identify viral particles in Burkitt's lymphoma cells. It belongs to the lymphocryptovirus (LCV) genus of the gammaherpesvirus subfamily (Fig. 1A). Th

  In this study, Oncomine, GEO and TCGA databases were used to analyze the expression of UBE2S gene in HCC and normal liver tissues to determine the relationship between UBE2S expression and prognosis of hepatocellular carcinoma. The potential function of UBE2S in HCC was analyzed by screening UBE2S c
