  Introduction DNA ligation is required during DNA replication and to complete almost all DNA repair events. In human cells, the DNA ligases encoded by three LIG genes are responsible for joining interruptions in the phosphodiester backbone [1]. These enzymes have distinct but overlapping functions

  It is well established that Shp-2 can function as a substrate for several RTK, such as PDGF or EGFR [23], [36]. To test whether DDR1 recognizes Shp-2 as its substrate, we overexpressed a catalytically inactive Shp-2 mutant together with DDR1b in 293 cells [31]. Immunoprecipitation of Shp-2 followed

  Our results also showed that the highest dose of Astressin2-B increased the rewarding effects of cocaine, since non-defeated animals treated with this dose developed CPP with a sub-threshold dose. We monitored the acute effects of 30 µg/kg of Astressin2-B and found an increase of anxiety in the open

  The enantiomeric ratio (ER) of chiral compounds accumulated in organisms has been found to be different among species (Borga and Bidleman, 2005, Harner et al., 1999, Warner et al., 2005, Wiberg et al., 2000), indicating enantioselective accumulation of chiral compounds are species-specific. The ER o

  WNV, a member of the genus Flavivirus within the family Flaviviridae, was first isolated in 1937 from a febrile woman in the West Nile region of Uganda (Brinton, 2002). Until 1999, WNV was mainly confined to Southern Europe, the Middle East, Africa, West and Central Asia, Indonesia and Australia. In

  In all available E2:E3 structures, the RING-type domain binds the E2 on a surface that is remote from the active site Cys (and therefore from the ubiquitin thioester) (Fig. 2). The non-contiguous E3-binding and active sites on the E2 imply that the role played by a RING to facilitate ubiquitin trans

  Nanocomposite films with a GNP-DNA filler concentration of 20 wt%, 30 wt%, and 40 wt% were investigated by electrical impedance spectroscopy before and after UV-C irradiation (Fig. 2). EIS data were fitted to a RC-circuit model and surface resistivity values were calculated from the fitted resistanc

  DGKs inhibition and signaling Local DAG levels are strictly controlled by a balance between synthesis and degradation rates. Both receptor controlled PLC-mediated production and DGK-mediated degradation are classically implicated in the control of “signaling” DAG. However, this dogma is starting

  Introduction The Bromeliaceae family is one of the most morphologically and ecologically diverse flowering plant families native to the tropics and subtropics of the New World (Benzing, 2000). They comprise >3000 species and are traditionally divided into three subfamilies: Pitcairnioideae, Bromeli

  The repeat sequence “TTAGGG” of telomere could be directly recognized by TERF1. TERF1 is indispensable for the maintenance of telomere Boc-Phe-Osu structure and integrity (Tan et al., 2017). Trf1 genetic depletion in vivo induces a persistent DNA damage response and telomere uncapping, which effecti

  In conclusion, the present study demonstrates that E2's antiapoptotic effects are significantly reduced by coadministration of progestogens. The combination of E2 and progestogens resulted in diverging effects on the expressions of ERs and PRs, which induced different effects on the cell growth of M

  Discussion Variable estradiol effects on cell proliferation have been reported according to animal species, tissues, and type of estrogen receptor [16,21,22,[29], [30], [31]]. In the kidney, 17βE was found to increase [3H]-thymidine incorporation in primary rabbit kidney proximal tubule xmu [30]

  Effects of estrogens on bone Estrogens play an important role in bone remodeling, as demonstrated by studies in mice in which the ER genes were deleted [21], [22]. ERβ compensates for the Cy3 hydrazide of ERα, and vice versa, but when both ERs are deleted a profound decrease in trabecular bone v
