  Enzymes repairing alkylated DNA Induction of the Ada regulon Methylated Ada is a strong activator for ada and alkA promoters. Although much weaker than the methylated form, unmethylated Ada acts alone as an activator for ada and alkA promoters. In contrast, the unmethylated protein present in

  To respond to the need for QNAT, commercial assays have been developed on automated systems. The first reagents for CMV and EBV VLs in whole blood were Abbott RealTime kits on the m2000 SP/RT system (Abbott Molecular Inc, Des plaines, USA) (M2000) [4,5] and Artus QS-RGQ kits on the QIAsymphony RGQ s

  Acetylcholinesterase and cholinergic signaling The concept of a synapse between a neuron and an innervated cell, and the receptors that mediated their interaction, was developed by Bernard, Ehrlich, Sherrington, Langley and others (see [7], [8], [9]. It was long debated whether transmission of ne

  In human neuroblastoma SH-SY5Y Kinase Inhibitor Library and in lymphoma Jurkat cells, Yamanaka et al. [56] showed that exogenously added 24(S)-hydroxycholesterol could be efficiently esterified by ACAT1. These results suggest that both ACAT1 and ACAT2 can control the oxysterol levels by directly es

  2020-06-22

  

  Environmental cues, such as microbial, dietary, and neuronal signals, regulate the differentiation and function of ILC3s. However, the identities of any additional cues and the receptors that detect them remain unknown. An important class of proteins enabling cells to sense extracellular cues are G-

  2020-06-22

  

  As small non-coding RNAs, microRNAs (miRNAs) can control gene expression at the post-transcriptional level by binding to the 3′-untranslated regions (3′-UTR) of messenger RNAs (mRNA) [15], [16]. miRNAs have been anticipated to regulate virtually all cellular mechanisms [17] and to play an important

  Although intact Chk is distributed throughout the nucleus and the cytoplasm (Fig. 1), the deletion of the SH2 domain greatly augments nuclear localization of Chk. The SH2 domain-deleted mutants might lose the ability to localize to the exterior of the nucleus due to a lack of the binding to a hypoth

  2020-06-20

  

  Estrogen receptors (ERs) belong to the third class of nuclear receptors (NR3) [23]. Two different forms of ER have been described, ERα and ERβ. They are coded by two distinct genes (ESR1 and ESR2, respectively) containing 8 transcribed exons that give rise to six conserved protein domains: domains A

  Arsenic is an endocrine disruptor with estrogenic activity. Further study has shown that arsenic exposure can significantly increase the expression of estrogen receptor-related genes, steroid metabolism-related enzymes and lung cancer-related genes in the lung tissues of female mice on the occurrenc
