  2020-10-05

  

  The occurrence of three Ag-NORs per metaphase and/or a maximum of three nucleoli per nucleus in most of the varieties may be explained by chromosomal rearrangements or unequal crossing-over events that induce the deletion of the fourth active rDNA loci. Also, the chromosome pair that showed less int

  2020-10-05

  

  Aldehyde dehydrogenase has been characterized as a cancer stem cell marker, which plays a key role in various biological processes in tumor, including cell proliferation, invasiveness and chemoresistance. Recent data of Abourbih et al reported that ALDH1 expression did not correlate with primary tum

  2020-10-03

  

  We also identified a role for the transcription factor p53 in the regulation of the Crm1 promoter. p53 can activate or repress the transcription of target genes. While activation generally occurs through binding of p53 to its consensus binding site in the promoter region of target genes, for example

  In this study, we further investigated the involvement of CRF1 and CRF2 receptors of the dPAG in the regulation of panic-related responses. For this, we used two animal models that associate escape behavior with panic attacks: the elevated T maze and the electrical stimulation of the dPAG (for a ful

  The aim of the present study was to investigate the acute effects of THC on resting state AZ 10606120 dihydrochloride neurophysiology, and to examine the impact of COMT genotype on these effects. Thirty-nine healthy volunteers participated in a randomised, placebo-controlled, crossover pharmacologi

  2020-10-02

  

  In rodents but not humans, two splice variants of Chk are identified as Ntk and Ctk, which possess and lack the N-terminal unique domain, respectively. While Ctk is abundantly expressed in the brain, Ntk is selectively restricted to myeloid and lymphoid cells, especially megakaryocytes [31]. This ra

  2020-09-30

  

  O-GlcNAc transferase OGT belongs to the metal-independent GT-B superfamily of glycosyltransferases, which has been well-reviewed previously [14,15]. OGT is an essential gene encoded on the X-chromosome, and it has two main regions: a long N-terminal tetratricopeptide repeat (TPR) region and a C-t

  2020-09-30

  

  As a co-factor, CIITA lacks the ability to recognize and directly bind to specific DNA elements to regulate transcription; instead, it relies on interaction with sequence-specific transcription factors (TFs) to be recruited to the chromatin. Therefore, the observation that CIITA binds to a specific

  Methods Results Discussion Here we have shown that two GPCR subtypes thought to trigger similar signalling events by coupling to Gαq in fact regulate different signalling networks via coupling to distinct G proteins. Thus global effects regulated by both receptors in events such as cardiac

• The in vitro enantioselective metabolism of pesticides

  2020-09-30

  

  The in vitro enantioselective metabolism of pesticides has been investigated by employing human liver microsomes, which are a reliable resource to perform MCL enantioselective risk assessment in humans (Carrão et al., 2019; de Albuquerque et al., 2018, 2016; Yao et al., 2016). The enantioselective m

  2020-09-30

  

  The importance of EBI2 for B cell function was first suggested by the dramatic upregulation of this receptor in EBV-transformed FLAG tag and further inferred from its regulation in activated and GC B cells (Birkenbach et al., 1993, Glynne et al., 2000, Shaffer et al., 2000). An involvement of EBI2

  Although our knowledge of the biochemical and biological functions of E3 ubiquitin ligases has increased in B-cell malignancies, a deeper characterization of cell-context dependent substrate regulation and biological relevance is needed.

  Immunofluorescence assays were performed to localize the enzyme during growth and differentiation to further characterize Giardia E1. As stated before, the assays showed that the PD 173074 generated recognized specific E1 forms (E1-114, E1-90 and E1-67 with anti-gNTE1; and E1-47 with anti-gE1CT); t

  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
