  2021-03-13

  

  The repeat sequence “TTAGGG” of telomere could be directly recognized by TERF1. TERF1 is indispensable for the maintenance of telomere XAP044 structure and integrity (Tan et al., 2017). Trf1 genetic depletion in vivo induces a persistent DNA damage response and telomere uncapping, which effectively

  Interestingly, increased level of both circulating ET-1 and urinary excretion of ET-1 have been observed in patients treated with nephrotoxic immunosuppressive agents as cyclosporine A and tacrolimus (Slowinski et al., 2002). Other nephrotoxic agents, such as cisplatin, also increase urinary excreti

  Tibolone is also efficacious on bone in elderly women and induces a clear reduction in bone turnover markers [50], [51]. Rymer et al. showed that, after 10 years of treatment with tibolone, the difference in bone mineral density compared with a placebo group was more than 12% for both lumbar spine a

  In this report, we established mouse models suitable for human retinal cell transplantation by introducing phosphodiesterase 6B (Pde6b) mutant allele from retinal degeneration (rd) mouse models into NOG background. Pde6b (rd1) and Pde6b (rd10) mice are well-studied and frequently used animal models

  Previous studies in the Swiss Webster mouse (Rosengren et al., 1995) and the Sprague–Dawley rat (El Sisi et al., 1993) have shown that retinol pretreatment potentiates the hepatotoxicity of paracetamol. The current study is designed to investigate further this interaction in mice. To accomplish this

  A brief history of RBR E3s RBR E3s were originally defined based on sequence alignments that predicted a tripartite motif of three zinc (Zn)-binding domains: two RING domains (RING1 and RING2) connected via an in-between-RING (IBR) domain [28], [29]. The prediction together with initial observati

  2021-03-13

  

  The RING domain was previously considered sufficient to confer ubiquitination by RING-type E3 ligases. However, recent reports have shown that sequences closest to the RING domain are also important in E3 ligase function. Residues like Tyr193 in RNF4 [40], Phe296 and Arg294 in BIRC7 [31], and Lys65

  Introduction O6-Methylguanine-DNA methyltransferase (MGMT) is a DNA-repair enzyme that specifically transfers alkyl adducts from the O6 position of guanine to the cysteine residue (Cys145) in its active site. In cancer cells, this ability of MGMT disrupts the cytotoxic actions of alkylating antic

  2021-03-13

  

  Introduction Protein ubiquitination is a posttranslational modification that plays a major role in almost all cellular processes in eukaryotes (Hochstrasser, 2009; Komander & Rape, 2012). It involves the covalent attachment of ubiquitin (Ub) via its C-terminal glycine carboxylate to a primary amine

  DDR1 upregulation in patients with kidney diseases such as lupus nephritis and Goodpasture's syndrome [8] as well as in animal models of kidney injury [7], [8], [18] suggests that DDR1 plays an important role in kidney disease. Studies in various mouse models of kidney injury indicate that DDR1 dele

  Acknowledgements Introduction α-L-Rhamnosidases (EC 3.2.1.40) are glycosyl hydrolases (GHs) that cleave terminal α-l-rhamnose from a large number of natural products [1]. The action of α-L-rhamnosidases (α-RHAs) has been reported, among others, on different complex substrates such as heteropol

  Constitutive activity of Ras/Raf/MEK/ERK pathway plays a critical role on melanoma growth, thus inhibition of activity of Ras, Raf and MEK can reduce ERK activity, leading to a decrease in melanoma cell proliferation, survival and invasion (Burotto et al., 2014; Paluncic et al., 2016).
