  In this work, we directly compared the effects on transcription by E. coli RNAP of several types of lesions commonly found in the genomic DNA: thymine dimer (CPD, cyclobutane pyrimidine dimer); 1,N6-ethenoadenine (εA); abasic site (AP); 8-oxoguanine (8oxoG), and thymine glycol (TG). We for the first

  Several reports , , , , have exploited the application of HRM for detecting differentially methylated DNA. Even though DNA methylation analysis by HRM cannot determine the methylation status of individual CpGs, it does provide a robust and inexpensive method to differentiate DNA based on the overall

  Mutation in BRCT-II domain (W893R) either in the full-length context or the C-terminal context greatly reduced the expression of LIG4 (Fig. 2B, Fig. 3B), suggesting the importance of BRCT-II domain in the maintenance of LIG4. In this regard, it might be noted that LIG4 protein was undetectable in Li

  Introduction In mammals there are ten known isoforms of the enzyme diacylglycerol kinase (DGK), as well as gene splice variants. Enzymes of this family all have a homologous active site but differ widely in their molecular mass, mechanisms of activation and biological function (Shulga et al., 201

  Results and Discussion Conclusions Based on their common NTP pyrophosphatase activity, similar size of the catalytic domains, and the conservation of glutamate residues, it was assumed previously that the MazG and HisE families were related to MutT and other Nudix family hydrolases (see Zhang

  As we all known, hypoxia is a hallmark of tumour microenvironment, which is a key regulator of tumour growth and metastasis [4]. Hypoxia meditates a series of cellular responses including angiogenesis by activating transcriptional factor hypoxia inducible factor (HIF), which is consist of an obligat

  More recently, evidence suggests that dysregulation of CRF signaling may also be implicated in panic disorder. For instance, polymorphisms in the CRF1, but not CRF2, gene have been associated with susceptibility to panic disorder in German and Japanese population samples (Ishitobi et al., 2012, Keck

  Discussion Cytomegalovirus (CMV) is a herpes virus that causes primary infection in normal hosts and re-activation infection in compromised hosts with impaired CMI, e.g., organ transplants. Following primary infection, which may be severe, CMV becomes latent in lymphocytes. Reactivation may occur

  More recently, it was discovered that BChE hydrolyzes the neuropeptide gut hormone, ghrelin [25], [26], [27], [28]. Nonetheless, because the enzyme reaction is very slow, those who first reported this finding were initially reluctant to attribute a real physiological role for that phenomenon. Our ow

  Although the mechanisms underlying the EP4-mediated increase in the frequency of mEPSCs via PGE2 remain unclear, mechanisms similar to those driven by EP2 may be involved because activation of both these receptor subtypes increases the intracellular concentration of cAMP (Nishigaki et al., 1995, Sug

  Enzyme activations Activated proteinases can unleash a deluge of tissue damage (Zucker et al., 2009). Once activated, the essential enzymes such as serine proteases and cysteine proteases cannot discriminate between self and non-self, burning away self-tissues (Chien et al., 2009, Laskar et al.,

  Although the amino MB05032 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, liver

  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
