  Introduction Mammalian proteases comprise both the peptidases or exopeptidases, which act at the N- or C-terminal positions of polypeptides, and proteinases or endopeptidases, which are capable of cleaving peptide bonds in the central regions of polypeptides. The endopeptidases are classified in

  Discussion Several DPP-4 inhibitors are currently available for use in the treatment of type 2 diabetes mellitus. Due to the different chemical structures there are marked differences both in the binding kinetics on the target enzyme [10] and also different pathways of elimination [13] exist. In

  DA neurons are capable of somatodendritic and axonal DA release, which may occur at synapses, as well as non-synaptic or asynaptic sites (Trudeau et al., 2014). DA may also be released at different timescales and in response to different DA neuron firing patterns (Grace et al., 2007). Furthermore, s

  In this study we generated mice in which the native Bcl6 locus was engineered to produce a form of Bcl6 containing a mutant RD2 domain that disrupts its repressor function. We found that RD2 domain is essential for pre-GC B cell differentiation and clustering into nascent GC within follicles, in par

  Egr1, together with catecholamine biosynthetic enzymes, such as tyrosine hydroxylase (TH), dopamine β-hydroxylase (DBH), and phenylethanolamine N-methyltransferase (PNMT), is induced in adrenal medulla by different types of stress (Liu et al., 2005, Morita et al., 1996, Nankova et al., 1993, Papanik

  Our current understanding of nucleotide metabolism in has made it possible to identify numerous proteins which serve essential roles in the life cycle of the parasite. One such protein is thymidylate synthase-dihydrofolate reductase (TS-DHFR), a bifunctional enzyme which is necessary for the produc

  Introduction Globally, lung cancer has the highest morbidity and mortality rates of all types of cancer, with 1.5 million patients newly diagnosed annually [1]. Approximately 85% of lung cancer cases are non-small cell lung cancer (NSCLC) [2]. The first-line treatment for NSCLC is surgical resectio

  Materials and methods Results Discussion Oxidative stress is a disturbance in the balance of pro- and antioxidant species, resulting in oxidative damage to membrane proteins, lipids, and DNA. Oxidative stress is a predisposing factor for the progression of metabolic diseases and liver injur

  In humans, individual differences in prefrontal dopamine are partially caused by the Val158Met single-nucleotide polymorphism on the catechol-O-methyltransferase gene (COMT). This gene controls activity of the COMT enzyme, which degrades extracellular catecholamines including dopamine. The Val varia

  Conclusion In the last year, significant advances in our understanding of ubiquitin transfer by IAPs and related E3 ligases have been made. The three crystal structures of the RING-bound E2~Ub show that the conjugate is bound by the RING domain in the closed conformation, where the I44-centered f

  A recent study revealed that in human glioma cells, DNA-PKcs interacted with the regulatory γ subunit of AMPK and positively regulated AMPK phosphorylation and activation under glucose-deprived conditions. This suggested that DNA-PK is an important regulator of AMPK activation in response to energy

  Nowadays, colorimetric assay has been applied in detecting DNA MTase activity. Li et al. used DNA modified gold nanoparticles (AuNPs) coupled with enzyme-linkage reactions to detect the activity of methylases [20]. In a previous study, our group presented a label-free colorimetric method, using unmo

  Although there was little to no expression change observed by TELI of the recA and ruvA genes upon CAA exposure, other specific repair pathways were induced by both CAA and SO and include the SOS-inducible gene sulA, the DNA repair gene ykfG, the mismatch repair gene mutS, the recombination and repa

  Introduction DHFR is an important enzyme in both mammals and microorganism including Mycobacterium tuberculosis (Mtb). It catalyzes folic Vatalanib conversion to dihydro and tetrahydro folic acid which is a crucial step in folate pathway [1]. Inhibition of folate pathway leads to interruption of th
