  2021-05-13

  

  Both progesterone and the calcium ionophore A23187 rely on the synthesis of cAMP by sAC to elicit exocytosis in human sperm (Fig. 2E-H and [8], [60]). We had reported earlier that digestion of endogenous cAMP with recombinant cAMP-specific phosphodiesterase 4D [9] or inhibition of its synthesis with

  2021-05-12

  

  The nitrophenols 34b–d were prepared as described in Scheme 3b. Nitration of phenols 39b–d with 1equiv of sodium nitrate in the presence of hydrochloric Y-27632 gave an inseparable mixture of 34b–d and 40b–d (1:1). This synthetic problem was successfully avoided as described below. Nitration of 39b

  2021-05-12

  

  The synthesis of the required substrates is shown in (see for experimental details). Treatment of heterocycle with DL-AP5 under basic conditions afforded a mixture of the mono-substituted product (22%) and the di-substituted compound (38%) which were separated by column chromatography. Compou

  2021-05-12

  

  Introduction With an annual world production of around 750 million tons, wheat is grown on more agricultural area than any other food crop and is the main source of plant protein in human nutrition [1,2]. Wheat is composed of 8–15% protein, from which 85–90% is gluten [3]. The unique viscoelastic a

  Inhibiting APC/C during Interphase and prior to Anaphase Because ubiquitylation by APC/C triggers cell division, it is essential that APC/C is restrained until cells are prepared for its substrates to be degraded. In addition to regulation by phosphorylation, an additional layer of control comes

  2021-05-12

  

  Although the implication of DA and glutamate signaling crosstalk in drug-evoked neuronal adaptations is well acknowledged, targeting the cognate receptors to alleviate symptoms is associated with a loss of efficacy over time and the appearance of severe sides effects, likely due to the involvement o

  2021-05-12

  

  A number of factors have been shown to remove blocking end groups in order to make the termini of DSBs ligatable. A common non-ligatable end is one that contains either a 3′ phosphate or 5′ hydroxyl. The polynucleotide kinase/phosphatase (PNKP) is the NHEJ processing enzyme responsible for removing

  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 chemokine receptor antagonist (Houjou et al., 2005, Pulfer and

  2021-05-12

  

  Dihydrofolate reductase (DHFR) is an excellent molecular target for this study because it has been and is currently studied by using different molecular modeling techniques [6], [7], [8], [9]. Kerrigan et al. have reported an interesting review about recent progress in molecular dynamics simulations

  As temperatures increase, rates of spontaneous deamination also increase such that hyperthermophilic organisms must have efficient mechanisms for dealing with this potential hazard.8., 9. The hyperthermophile Methanococcus jannaschii has both a dCTP deaminase (encoded by the gene at locus MJ0430) an

  Atg4 cleaves Atg8 at the peptide bond on the glycine residue at the C-terminus, thus allowing the conjugation of Atg8 to phosphatidylethanolamine (PE) with the participation of other autophagy molecules. Atg4 can also serve as a deconjugating enzyme, which cleaves the amide bond of the conjugated At

  2021-05-12

  

  Proteolysis by CPs is crucially important for cereal seed development and germination. However, these enzymes must be tightly controlled. Pre-harvest sprouting is a phenomenon in which the control of CPs is disrupted. This disruption manifests in the premature synthesis and activation of CPs, leadin

  Introduction Analyses of genomic alterations in cancer have identified epidermal growth factor receptor (EGFR) as one of the most potent “oncogenic driver” kinases that is present in many epithelial tumors including endometrial, breast, prostate, skin, esophagus, lung, stomach, colorectal, and re

  Among the different factors that modulate Schwann cell biology, several studies pointed out the role played by neuroactive steroids, in particular progesterone (P4) and its derivatives dihydroprogesterone (DHP) and allopregnanolone (ALLO). Schwann next are steroidogenic, possessing the entire enzym
