  2020-05-28

  

  In general, cellular senescence is considered a programmed response to stress that can be activated by oxidative stress, irradiation or action of substances or drugs. These stressors cause DNA damage and, through the action of specific proteins (p53 and p21), lead to cell senescence (di Fagagna, 200

  In this paper, we describe a facile and universal method for in situ crosslinking of DNA micelles, using spherically directed reduction of metal ions. As shown in Scheme 1A, a single-stranded DNA (ssDNA) consisting of a ligand domain, a template domain, and a lipid domain was designed as a monomer t

  Reports on the participation of NDH2 along with other respiratory complexes in the formation of a large supercomplex (Grandier-Vazeille et al. 2001) or even a respirosome-like structure in S. cerevisiae mitochondria (Matus-Ortega et al. 2015) are very intriguing. Similarly, in Y. lypolytica mitochon

  Soon after the discovery of ET1 and the cloning of its ETA and ETB receptors, low-molecular-weight compounds were identified that can prevent the binding and effects of radioactively labeled ET1 3, 5, 6, 8. Initially, these ERAs resulted from screening efforts (e.g. BQ123 39, 49 and bosentan [50]).

  Introduction Formate dehydrogenase enzymes (FDHs) are a group of heterogeneous proteins that catalyse the reversible formate () oxidation to carbon dioxide () (Eq. (1)). These enzymes are classified in two families, one gathering the enzymes that hold no redox-active centres and another that includ

  Alcohol and the amygdala Alcohol and the CRF1 system Given the marked effects of alcohol on inhibitory neurotransmission in the amygdala and the regulation of amygdalar GABAergic activity by CRF and activity at the CRF1 receptor, the CRF system is a logical site for the actions of alcohol in t

  Materials and methods Results Discussion Intra-BNST injections of NOC-9 (at all doses) were able to produce freezing and anxiogenic-like effects. Freezing was observed immediately after the NO donor injection and lasted about 2–3min (data not shown). When exposed to the EPM 5min after intra

  When six chemical inhibitors were incubated with TRB or TRC and human liver microsomal preparation, HLM2, the results showed that ketoconazole (a CYP3A4 inhibitor) was very effective in inhibiting 4β-C hydroxylation of TRB and TR, whereas sulfaphenazole (a CYP2C9 inhibitor) and quinidine (a CYP2D6 i

  Introduction Activation of epidermal growth factor receptor (EGFR)-receptor tyrosine kinases (RTKs) is a key factor in the progression of non-small cell lung cancer (NSCLC). EGFR-RTKs cause proliferation, invasion, metastasis, and angiogenesis, as well as suppress apoptosis, in lung adenocarcinoma

  To get an indication whether GBM-derived 25-OHC could act as a chemotactic signal for monocytes, lipid extracts of GM133 media were used in THP-1 migration assays. Although an indirect approach, these experiments revealed that medium lipid extracts induced monocyte migration in a quantitatively comp

  Future perspectives Understanding how peptides are degraded, particularly those which may be therapeutically useful, such as GLP-1, has proved to be invaluable in providing a rationale for the development of a novel class of therapeutic agents. However, while DPP-4 plays an important role in the

  It is currently believed that acute morphine administration can impair learning and memory (Friswell et al., 2008). Chronic morphine treatment can also impair access to and retention of spatial memory (Spain and Newsom, 1991, Zheng et al., 2002). Using the Morris water maze experiment, we have previ

  DGKδ deficiency caused a significant increase in the SERT protein level, but its mRNA level was not affected (Fig. 1). These results suggest that SERT protein stability is directly reduced by interaction with the DGKδ protein. In contrast, DGKδ deficiency regulated both TPH-2 and MAO-A protein and m

  As part of a program to explore the key binding interactions between the core of 1 and DGAT-1 a systematic analysis of the aminopyrimidine subunit was initiated. A potential approach to improving passive permeability within this series would be to increase lipophilicity via incorporation of substitu

  Here we found that these leukotriene antagonists also inhibit the effects of nucleotides acting at P2Y receptors in dU937 cells, which are known to express a number of nucleotide receptors, such as P2Y2 or P2Y4[30]. In an effort to characterize the P2 receptor subtypes subject to negative modulation
