  In the present work, we ask whether rNMP incorporation is an evolutionarily conserved property of DNA synthesis in Archaea. For this purpose, we used the best characterized hyperthermophilic anaerobe, Pyrococcus abyssi GE5 [47]. This strain duplicates its genome as fast as Bacteria, supported by euk

• DNA methylation is associated with transcriptional silencing

  2021-08-26

  

  DNA methylation is associated with transcriptional silencing of tumor suppressors or other genes important for normal cellular function and plays an important role in the development of cancer and other diseases (such as breast and colorectal cancers) [19]. DNA methyltransferases (MTases) are a fami

  Development of a liquid chromatography-mass spectrometry method to improve detection of PA species detection Liquid chromatography-mass spectrometry (LC-MS) is a powerful tool to detect different molecular species of phospholipids in Propylthiouracil (Houjou et al., 2005, Pulfer and Murphy, 2003

  Material and methods Results Discussion Monomeric CDK5 shows no enzymatic activity and requires the association with a regulatory partner for activation (Dhavan and Tsai, 2001). Here, we found that CDK7 might be one of the partners required for activation of CDK5 in the skin tissue, based o

  2021-08-26

  

  Among prostaglandins (PG), PGD2 remained the most elusive species for a long time and was initially regarded as having negligible biological activity [1]. In 1974 its inhibitory effect on platelet aggregation was discovered by Smith et al. [2] and Mills & McFarlain [3], and both pressor and depresso

  Next, our exploration shifted to modifications at the lateral chain of the benzoquinone nucleus (SAR 2). Considering that the CK2 inhibitory activity is favoured by the presence of the -Ph-4-NO2 (SAR 1), the subsequent analogues were investigated with this moiety retained. The influence of the side

  RNA-seq results also support the similarity between ESC- and YS-derived B-1 progenitors. Bmi1 expression, known as an important gene for self-renewal ability in stem cells, was reduced in ESC-derived B cells compared with YS-derived B cells, and Bmi1 overexpression improved the engraftment of ESC-de

  Although the presence of calcium in RHA-P active site is confirmed by the homology modeling, some additional observations can be made following the metal depletion and reconstitution experiments performed on RHA-Phis. EDTA-treated RHA-Phis recovers its activity in the presence of divalent cations su

  While showing that deletion of EP1 maintains femur bone volume fraction and trabecular bone parameters during aging, perhaps more importantly we have also demonstrated that increased initial BV/TV in EP1 is protective against OVX-induced bone loss. That is, while mice lose an approximately equal pe

  Discussion The N-terminal domain of DDRs has long been recognized as a member of the DS superfamily (Johnson et al., 1993, Karn et al., 1993), and its role in collagen binding is understood in atomic detail (Carafoli et al., 2009, Ichikawa et al., 2007). Our crystal structure shows that the secon

  A role for the E2–E3 interface in governing mono- versus polyubiquitination is not mutually exclusive with that of the E2 backside, which has previously been shown to mediate polyubiquitination through its ability to bind to Ub [21], [25], [33]. Brzovic and colleagues first demonstrated the importan

  Advances in the total chemical synthesis of ubiquitin have enabled the efficient synthesis of new and improved ubiquitin-based reagents. Using an optimized linear synthesis, ubiquitin can now be easily obtained in high yield and purity [35]. Using this synthetic methodology, ubiquitin can be functio

  Introduction Double strand break (DSB) is the most deleterious damage that threats DNA integrity. This frequent damage arises from environmental stress like UV, chemical agents or ionizing radiations (IRs). Although environmental stress does not lead directly to DSB, it produces caspofungin damage

  The ability of minor groove binding agents to inhibit the activity of DNA helicases is not without precedence. Similar effective inhibition of the unwinding of DNA by the BLM and Werner's DNA helicases by the minor groove binder distamycin A has been observed. Further, and similar to RecBCD, interc
