  In 2015–2016, half a century after its first biochemical characterization as a template-independent polymerase, it was shown that TdT can, firstly, assemble a DNA synapsis by itself, optimally with one micro-homology base-pair between strands [] and secondly, perform a template-dependent nucleotid

  Conclusion In conclusion, DNA methylation is a major epigenetic mark, which regulates temporal and spatial expression of the testicular genes required for normal spermatogenesis process. There are two types of methylation, maintenance and de novo methylation, which are catalysed by DNMT1, DNMT3A

  Citrus plants are of great interest because they contain large amounts of flavonoids, and citrus fruits and their juices are consumed in large quantities around the world [18]. The flavonoid contents and profiles of citrus juices vary greatly with the type of fruit. It has been determined that citru

  However, recent studies revealed that the function of Crm1 might not only limit to nucleocytoplasmic transport, but also be involved in regulation of centrosome duplication. As the major microtubule organizing centers in animal cells, centrosomes play a significant role in cell cycle, spindle format

  Stable carbon and nitrogen isotope ratios in bone collagen and carbon isotope ratios in bone apatite data were obtained by the means of the techniques described in supplementary data (SD1). For collagen, standard indicators have been used to assess its preservation, such as collagen yield, carbon an

  Hence, what is proposed here is a technique highly used in reliability engineering: Software Rejuvenation[4], [21], a technique of proactive fault tolerance in which the system is periodically reboot to clean the memory. In fact, it is well known that most critical SW failures are transient. These m

  The P4H activity and the large number of 4-Hyp residues that are formed, amounting to half of all the Pro residues or 10% of all residues, have been identified as having a clear role in the structure and chemistry of the triple helix [3]. The role of the rare 3-Hyp residues is less clear and is stil

  EphB4 promotes tumor growth by stimulating angiogenesis through EphrinB2 [18]. However, the distinct and specifically involvement of HL 2448 and veins in the tumor angiogenesis of all tumor grades is unclear. Our results indicate that the relation between EphrinB2 and EphB4 stained blood vessels was

  Although the mechanisms underlying the EP4-mediated increase in the frequency of mEPSCs via PGE2 remain unclear, mechanisms similar to those driven by EP2 may be involved because activation of both these receptor subtypes increases the intracellular concentration of cAMP (Nishigaki et al., 1995, Sug

  In contrast, T-bet downregulated the expression of Tfh functional molecules, CD40L, ICOS, and IL-21; accordingly, T-bet overexpression abrogated the helper function of IL-12-stimulated CD4+ T cells. Thus, T-bet seems more involved in the downregulation of the helper functions than in the differentia

  The question arises as to how the massive conformational changes determining whether APC/CCDC20–MCC is inhibited or able to catalyze MCC ubiquitylation are naturally controlled? This transition likely involves APC/C regions near the subunit APC15, because reducing cellular APC15 levels stabilizes M

  Introduction Protein modification by ubiquitin and ubiquitin-like proteins is one of the most common and important regulatory mechanisms in biology (Finley et al., 2004, Pickart, 2004). Ubiquitination is carried out by an enzymatic cascade consisting of three steps. In the first step, ubiquitin i

  ATP-dependent DNA ligases in vertebrates are divided in three families [7]. Family I DNA ligases are responsible for sealing the nicks during DNA replication and in long-patch base excision repair (BER). Family III DNA ligases are involved in short-patch BER. Lastly, family IV DNA ligases are involv
