  Phenotypic responses: alkylation-induced cell death and mutagenesis E. coli alkB mutants were isolated in a screen for strains specifically sensitive to the cytotoxicity of MMS but not UV-irradiation. This was the first indication that the AlkB protein is a primary cellular defence against alkyla

  It would be very useful if unphosphorylated CK1s could be prepared using an E. coli expression system without the troublesome in vitro phosphatase treatment. So far, it has been shown that coexpressed λPPase, a Mn2+-dependent protein phosphatase that can dephosphorylate phospho-Ser/Thr/Tyr [20,21],

  2020-02-03

  

  The selective estrogen receptor modulators (SERMs) are another type of estrogen receptor ligands. The main difference between SERMs and xenoestrogens relies on the fact that SERMs present functional duality and are able to act both as agonists and antagonists of the estrogen receptors in different t

  Studies have recently raised concerns about the potential role of parabens in breast cancer, as these chemicals are commonly detectable in human breast cancer tissues. An analysis of 160 breast tissue samples collected from 40 mastectomies for primary breast cancer in England showed that at least on

  Curcumin is found safe in several human studies (Chainani-Wu, 2003; Cheng et al., 2001; Dcodhar et al., 2013), in contrary, the toxicity of curcumin has also been reported under some specific conditions (Burgos-Morón et al., 2010). Moreover, it chemokine receptor antagonist was also reported that c

  Both receptors belong to the large family of G protein-coupled receptors (GPCRs) [4,5], which often appeared as monomers, dimers and higher order aggregates [6,7]. There is evidence that these receptor-complexes can modulate the functionality and the pharmacology of the receptors [8,9] by sequesteri

  We postulate that OT contained in milk during early postnatal development causes a mild enteroprotective preconditioning of the ER (Fig 9). This is perhaps akin to a mechanism shown by others [50], [51], [52], which is characterized by selective activation of the IRE1a/XBP1/eIF2a (via PKR) UPR pathw

  In the present study, we used a new luminescent method to measure CYP activity with Luciferin-ME as a substrate which is used for wide ranges of mammalian CYPs, including CYP1A2, CYP2C8, CYP2C9, CYP2J2, CYP4A11, and CYP4F3B. As a result, no significant modulations of CYP activities in B[a]P exposure

  MTT results show that, both pancreatic cell lines were quite sensitive to camptothecin (CPT), a well known topoisomerase I poison. Interestingly, CPT does not show any selectivity over cancer cell lines probably due to the duplication times for cancerous (MIA PaCa-2) and immortalized healthy (HPDEC)

  Casein Kinase II (CK2) Casein Kinase II (CK2) is a ubiquitous serine/threonine-selective pro-oncogenic protein kinase that has become a more prominent target for research due to its effects and key role in tumorigenesis (Gowda et al., 2017a, Pinna, 2002). CK2, a well-conserved, pleiotropic kinase

  Ligand-independent activation of neuronal nuclear estrogen receptors may also continue to occur in absence of ovarian estrogens. AF-1 requires intracellular kinase cascade-dependent phosphorylation of specific residues in the A/B domain of nuclear estrogen receptors (Le Goff et al., 1994; Kato et al

  Experimental Procedures Acknowledgments Bisphenol A (BPA) has been recognized as one of the most potent endocrine disruptors, functioning even at very low doses. Although it is anticipated that (+)-MK 801 Maleate receptor (ER) would mediate these effects of low-dose BPA, studies revealed th

  Multiple protein species are known to naturally exist for the transmembrane receptors DDR1 and DDR2. Five splice variants have been characterized for DDR1 (“a” through “e”). The d and e isoforms lack the intracellular kinase domain of DDR1. The splicing of DDR1 to various extents has been reported i
