  2020-03-23

  

  In this study, using REMD with the crystal environment, we investigate the effect of cryo-cooling on the crystal structure of Escherichia coli DHFR. DHFR is an important model enzyme (for review, see, e.g., (30)), and has been studied for decades (31, 32, 33, 34, 35, 36, 37, 38, 39, 40, 41, 42, 43).

  The collagen field undoubtedly regains attractiveness with the emergence of new concepts (cell niche, regulation of growth factor bioavailability, mechanotransduction, cell microenvironment sensing) and new tools to investigate their in vivo functions (atomic force microscopy (AFM), second harmonic

  Then the mechanisms responsible for BPA induced up regulation of ERRγ were further investigated. Recent studies indicated that Akt and MPAK can modulate the protein levels and transcriptional activities of ERRγ (Heckler et al., 2014, Sun et al., 2014). Previous studies also indicated that BPA can ac

  Competing interests Acknowledgements Introduction Diacylglycerol kinase (DGK) phosphorylates diacylglycerol (DG) in biomembranes to produce phosphatidic Kartogenin (PA) [1], [2], [3], [4], [5], [6]. To date, ten mammalian DGK isozymes (α, β, γ, δ, ε, ζ, η, θ, ι and κ) have been identified.

  Introduction Natural killer (NK) cells have an unique ability to directly lyse transformed, virus-infected or stressed cells without prior sensitization or major histocompatibility complex (MHC) class I restriction [1], [2]. They were initially defined and shown to be important effectors of the i

  Haggar et al. reported the synthesis of two new series of 8-(2-imino/oxo/thioxo pyrimidin-4-yl)-4-methyl-6-nitro-2-oxo-2H-chromen-7-yl benzoates 56 (X=O, S, NH) and 8-(pyrazol-3-yl)-4-methyl-6-nitro-2-oxo-2H-chromen-7-yl benzoates 57 [Y=C(O)CH3, 2,4-(NO2)2C6H3]. The 8-acetyl-4-methyl-6-nitro-2-oxo-2

  Arsenic is an endocrine disruptor with estrogenic activity. Further study has shown that arsenic exposure can significantly increase the expression of estrogen receptor-related genes, steroid metabolism-related enzymes and lung cancer-related genes in the lung tissues of female mice on the occurrenc

  Introduction Hydrogen sulfide (H2S) and nitric oxide (NO) are important gasotransmitters in the cardiovascular system and instrumental to the fine control of vascular tone [1] and cellular function [2]. NO is synthesized from l-arginine by calmodulin-dependent endothelial nitric oxide synthase (e

  Rationale and hypothesis To discover an allosteric inhibitor of EGFR, Jia et al. (2016) screened a library of 2.5 million compounds at 1 μM ATP concentration in opposition the purified EGFR L858R/T790M mutant enzyme. 1322 best hits were found from this round of screening. The pinnacle hits had be

  The human MARCH family comprises eleven members (termed MARCH-1 to 11), of which nine are transmembrane proteins. In this review, we focus on the role of the membrane-spanning MARCH proteins and how their transmembrane regions can mediate interactions with their target proteins. Therefore, the cytos

  A different example of substrate-dependent activation is seen in CSN5, a JAMM-type DUB found in the eight subunit COP9 signalosome (CSN) [34]. The CSN deconjugates NEDD8 (neural precursor cell expressed developmentally downregulated 8) from Cullin Ring ubiquitin E3 ligases (CRLs). Through this activ

  Results and discussion Conclusion We have constructed a series of potent and greatly selective DPP-4 inhibitors with pyrazolo[1,5-a]pyrimidin-7(4H)-one core surrogates. The modification of the core led us to b2 which has IC50 of 80 nM and > 1000 fold selectivity over DPP-8 and DPP-9. We utiliz

  Midazolam oral clearance is used for characterization of both intestinal and hepatic CYP3A activity. However, the identification and subsequent use of metabolic markers of CYP3A activity can eliminate the need for unnecessary administration of probe drugs such as midazolam. Such metabolic markers wo

  2020-03-21

  

  CDK6 lacks DNA-binding domains and nuclear localization sequences, and therefore will probably be transported to the nucleus by a ‘piggy-back’ mechanism and needs to contact its specific sites indirectly through DNA-binding proteins. Besides NF-κB p65, a further candidate transcription factor is PAX
