  2021-03-25

  

  Proteins that associate to PCNA are characterized by having conserved motifs as the PCNA-interacting protein (PIP) motif [29,30], its variant PIP-like motif [31,32] or the APIM motif (Alk B homologue 2 PCNA interacting motif [33,34]); for instance, p21 contains a PIP motif [30], and DNA polymerases

  Tumor-associated macrophages (TAMs)—one of the limiting factors in anti-tumor immunity—are associated with the poor clinical outcome in most carcinomas, owing to their potential to promote angiogenesis and local invasion, increase the metastasis of tumor cells, and inhibit the anti-tumor immunity.11

  2021-03-25

  

  In the cytoplasm, the ternary CRM1–cargo–RanGTP complex is disassembled by the action of Ran-binding proteins RanBP1/2 and RanGAP. A recent kinetic study showed that the Ran-binding domains (RanBDs) of the cytoplasmic proteins RanBP1 and RanBP2, but not RanGAP, accelerate dissociation of NES from CR

  Stress is usually comprehended as an event affecting mainly the HPA axis and initiating the alarm reaction represented by activation of the adrenal medulla. This means that the levels of related hormones and neurotransmitters are significantly elevated during and after the stress. CRF, following its

  2021-03-24

  

  Introduction Hepatocarcinoma is a common and aggressive form of cancer (Trad et al., 2017). Due to a high rate of postoperative recurrence and metastasis, the prognosis for HCC remains dismal (Wang et al., 2017a, 2017b). Subclinical metastasis is the major cause responsible for tumor recurrence and

  Abbreviations Introduction Collagen-induced DDR activation A key feature of DDRs is their ability to bind both fibrillar and non-fibrillar collagens (Shrivastava et al., 1997, Vogel et al., 1997). DDR1 and DDR2 recognize the GVMGVO (O, hydroxyproline) motif within fibrillar collagens I–III

  As retinol was not inducing any of the isoforms of CYP450 responsible for the bioactivation of paracetamol, we decided to examine retinol's effect on renal and hepatic glutathione to determine whether retinol was potentiating hepatotoxicity through a mechanism of glutathione depletion. Studies, util

  Conflict of interests Introduction Ubiquitylation is a post-translational modification which impacts almost every biological process in the cell. Dysregulation of the ubiquitylation pathway is associated with several diseases, including cancer, neurodegenerative disorders, and immunological dy

  Oxidation of N-hydroxyguanidine 1 by DbH was studied by HPLC and some oxidation products for 1 could be characterized. The compounds generally observed with iron-containing systems are 4-methoxyphenylurea 11 and 4-methoxyphenylcyanamide 12 (Fig. 2). Oxidation of N-(4-chlorophenyl)-N′-hydroxyguanidin

  Our results indicate a deregulation of DNA methylation machinery during seed development in apomixis. Since DRM2 is targeted loci through an RNA-directed DNA methylation (RdDM) pathway involving 24-nt siRNAs (Stroud et al., 2014, Law and Jacobsen, 2010) and differentially expressed between apomict a

  In summary, these results are consistent with our hypothesis that chemical nitrosation of BMAA to N-BMAA results in the formation of an alkylating agent. Furthermore, we have shown that N-BMAA is more toxic than BMAA itself. Previously, methylazoxymethanol (MAM), which is also present in the cycad n

  While the mechanism of DHODH inhibition-induced differentiation is not fully understood, this phenomenon may be caused by pyrimidine depletion. Pyrazofurin, an inhibitor of OMP decarboxylase, was able to induce differentiation and suggests pyrimidine depletion as a potential mechanism (Sykes et al.,

  Six substrate recognition sites (SRS1-SRS6) have been identified at positions 102-123, 204-209, 238-244, 301-319, 374-382 and 483-492 (Table 2, underlined residues) based on Gotoh's proposal [30]. CYP3A163 displays the similar characteristic long sequences between helices F and G presenting two addi

  Redundancy of tumor promoting signaling pathways is one of the mechanisms that prevent a lasting effect of targeted therapies, as has been demonstrated by the growing number of alternative pathways that confer resistance to EGFR-targeted therapies [3]. We show here that CSF-1R can, at least partiall
