  Acknowledgment This work was supported by the Estonian Science Foundation (Grant ETF8862). Introduction In higher eukaryotes ionizing-radiation (IR) induced DNA double-strand breaks (DSB) are primarily repaired by the non-homologous end joining (NHEJ) pathway [1]. Ku, a heterodimeric protein

  Does a universal mechanism for TLS exist? Our previous studies using the bacteriophage T4 DNA polymerase generated the model provided in Fig. 7 that quantifies the molecular forces influencing key steps in the polymerization pathway during the replication of a non-instructional versus miscoding DNA

  In our recent study, we established a procedure to examine the chromatin binding of XRCC4 using a biochemical fractionation analysis using a detergent Nonidet P-40 [22]. In this study, we investigated the role of LIG4 and its subdomains in the recruitment of XRCC4/LIG4 complex to chromatin. Mater

  2021-06-02

  

  Enzymes involved in microbial steroid degradation are generally not expressed constitutively, but they are upregulated depending on which steroid substrates are present [17,81]. Thus, a cell-free extract prepared from testosterone-adapted C. testosteroni ATCC 11996 cells displayed a 1(2)-dehydroge

  2021-06-02

  

  Cytochromes P450 (CYP 450) are a superfamily of hemoproteins containing a heme cofactor, which are widely distributed in animals, plants and microbes (Hannemann et al., 2007). CYP450 exhibits a variety of biological functions including biotransformation of drugs, detoxification of endogenous and xen

  2021-06-02

  

  Within the BLA, both CRF and the CRF1 receptor have been shown to functionally regulate synaptic activity. In vivo, CRF release into the BLA originates from projections from the CeA (Roozendaal, Brunson, Holloway, McGaugh, & Baram, 2002). Central administration of both CRF and CRF1 agonists has been

  In this study, we further investigated the involvement of CRF1 and CRF2 receptors of the dPAG in the regulation of panic-related responses. For this, we used two animal models that associate escape behavior with panic attacks: the elevated T maze and the electrical stimulation of the dPAG (for a ful

  In the context of our ongoing studies to define the phytochemical and biological properties of oxyprenylated secondary metabolites of plant and fungal origin, we wish to report herein the investigation on the interaction of some natural and semisynthetic O-alkylcoumarins with promising ChE inhibitor

  2021-06-02

  

  The estrogenic activity of steroids with a C19 methyl group may provide a selective advantage in estrogen physiology that is not provided by E2. In this regard, 5α-androstanediol has been proposed to be a second physiological estrogen in fetal mouse Ipratropium Bromide based on the timing of ERβ sy

  The interaction of EPAC2 with Rim1 has an important role in regulating neurotransmitter release. In addition, a recent EPAC2 knockout mice model study provides evidence that EPAC2 promotes transmitter release by maintaining the readily releasable pool (RRP) at mossy fiber (MF) synapses in the hippoc

  Compared to ET-1, all agonists tested showed a 2–4 fold bias for the G protein constrictor assay compared to the β-arrestin assay (Table 1). This preliminary analysis indicated that at least modest pathway bias for endogenous ET peptides is possible, however the physiological significance of this, i

  Protein deubiquitination is becoming increasingly instrumental in understanding the complexities of the Ub system. Adding to this complexity is the discovery of bacterial effectors with DUB activity that have structurally adapted themselves to interfere with the eukaryotic Ub system (Pruneda et al.,

  2021-06-01

  

  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

  Our data also showed that D2 dopamine receptor was down-regulated in the hippocampus, NAc and striatum of F1-MEP animals, which was only significant in the hippocampus. Both agonists and antagonists of D2 dopamine receptor are able to decrease heroin self-administration (Hemby et al., 1996; Rowlett

  Common features of TdT, pol μ and pol λ TdT, pol μ and pol λ remain in a closed conformation throughout their catalytic cycle, contrary to pol β [24•, 53, 54•]. One possible explanation for this observation is that they have traded fidelity (which requires open-to-closed transition) for a very ti
