  Our previous studies have shown that in a preimplantation mouse embryo the proportion of inner to outer cells (i.e. precursors of ICM and TE, respectively) is regulated by a different frequency of differentiative cell divisions at the 8- and 16-cell stages. Low number of inner blastomeres generated

  2021-03-19

  

  The generation of ROS, in addition to eliciting oxidative stress, is an important proapoptotic signal (Ott et al., 2007). Apoptosis is clearly associated with the production of ROS, since ROS generation occurs in the mitochondrial respiratory chain and disturbs mitochondrial homeostasis, which plays

  Introduction Concern has been raised over free estrogens (estrone [E1], 17ß-estradiol [E2] and 17α-ethynylestradiol [EE2] particularly) in the past decade due to their endocrine disrupting effects on environmental biota [1], [2]. Estrogens are excreted by vertebrates primarily as sulfate or glucu

  2021-03-19

  

  Introduction Cholesterol plays a pivotal role as a constituent of biological membranes and as a precursor for vitamins, hormones and bile acids. Accordingly, its production, distribution, and elimination must be tightly regulated at the cellular and organismal level. Accordingly, dysregulated chole

  2021-03-19

  

  In plants, SUMOylation has been shown to modulate plant hormone signaling (Lois et al., 2003, Miura et al., 2009, Conti et al., 2014), root stem cell maintenance (Xu et al., 2013), and responses to abiotic and biotic stress (Lois, 2010). Many of the plant biological processes regulated by SUMOylatio

  In the present work, we have investigated the reactivity of N-aryl-N′-hydroxyguanidines 1a–d (see Scheme 1 for structures) with the water-soluble Cu(II) complex 8. Using EPR and UV–Visible spectroscopy, we have shown that the studied N-aryl-N′-hydroxyguanidines 1a–d can bind and transfer electrons t

  The photocleaving properties of 1 were studied by performing ΦX174 photocleavage assays. Light irradiation of the mixtures of increasing amounts of 1 with supercoiled DNA caused>90% supercoiled form relaxation and approximately 5% of linearization for the higher concentrations of 1 (1:10bp and 1:2bp

  The biological significance of DNA ligases is attributed to their function in DNA replication, recombination and/or DNA repair [1], [2]. In vertebrates, three different DNA ligases I, III and IV are recognized. DNA ligase I is essential for the Okazaki fragments’ ligation during lagging-strand DNA s

  Protein acetylation Several reports show that MTX is able to induce acetylation of histones and other proteins. Extensive studies have established that histone acetylation is primarily associated with gene activation. Acetylation occurs at lysine residues on the amino-terminal tail of the protein

  Collagen compaction and alignment are generated by cell-mediated contractile forces (Stopak and Harris, 1982). The transmission of actomyosin forces to collagen has been mainly attributed to integrins and the activation of the Rho-ROCK pathway (Clark et al., 2007, Kural and Billiar, 2013, Provenzano

  Introduction Eicosanoid lipid prostaglandin D2 (PGD2) is the major prostaglandin produced by activated mast nmda receptor (Lewis and Austen, 1981). The physiological function of PGD2 is mainly mediated by two G protein-coupled receptors (GPCRs), PGD2 receptor 1 and 2 (DP1 and DP2), which share mode

  The mechanism by which these HIV-PIs impair skeletal muscle palmitate transport and oxidation has been partially elucidated. CD36 (also referred to as fatty cp-690550 translocase; FAT) is a transmembrane protein involved in the transport of long-chain fatty acids (LCFA) across cellular membranes. I
