  Acknowledgments Introduction Cell cycle arrest or delay may occur at 3 major checkpoints, i.e. G1/S, intra-S and G2/M. p53 has a central role in controlling the G1/S checkpoint, and its loss or deactivation, occurring in the majority of cancers, forces cancer cells to rely on the S and G2/M ch

  2021-06-03

  

  The reaction of chitosan with DVS should take place primarily through a nucleophilic attack of the vinyl sulfone groups to the amino groups in chitosan [39,50], although its hydroxyl groups can also be involved, as it happens when using agarose [35]. These reactions create very stable secondary amin

  A wealth of studies support the key role of high NO in promoting higher blood flow and thus greater O2 delivery to working tissues in healthy Tibetans and thus partly compensate hypoxia induced low arterial O2 content [7,9,27]. We observed high eNOS mRNA, protein and enzyme activity in Ladakhi women

  Methods Results Discussion I/R induces oxidative stress and increases the intracellular levels of ROS, resulting in tissue damage [31]. ROS is generated by mitochondrial electron transport chain, nicotinamide Matrine dinucleotide phosphate (NADPH) oxidase complex, xanthine oxidase and NOS [

  While we previously demonstrated that TraG is inhibited by specific transglycosylase inhibitors and that enzymatic activity is strongly reduced upon mutation of the potential catalytic core (Arends et al., 2013), the enzymatic mechanism of both domains was not assigned. Here, by mass spectrometry an

  Acknowledgements Introduction Supramolecular collagen assemblies are crucial for the mechanical stability of animal bodies (Myllyharju and Kivirikko, 2004). The basic collagen structure is a triple helix of three chains containing multiple Gly-X-X' repeats; X and X' are often proline and 4-hyd

  Our research has demonstrated that the absolute bioavailability of oxymatrine, having a similar structure with OSC, was only 6.79±2.52%. About 50% of OSC was converted to its active metabolite SC in vivo; hence, the absolute bioavailability of OSC was speculated to be poor as well [24]. Understandin

  The E1 enzyme is the apex for downstream enzymatic cascades and signaling pathways mediated by Ub and Ub-like proteins (Ubls) (Pickart, 2001). Studying characteristics of E1 and its catalytic functions may throw light to the role of ubiquitination in cell development. All known eukaryotic E1 are mon

  2021-06-03

  

  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

  2021-06-02

  

  Two major mechanisms including apoptosis and oxidative stress have been suggested for MTX-induced cytotoxicity (Hafez et al., 2015; Neuman et al., 1999; El-Sheikh et al., 2015). It has been reported that MTX promotes cell death via apoptosis in both cancerous and non-transformed cells (Mazur et al.,
