  2020-12-26

  

  Introduction Prostaglandins are important local mediators in a host of reproductive processes including ovulation, fertilization, embryonic development, luteal regression, and parturition (Ushikubi et al., 2000). Prostaglandin E2 (PGE2) is among the more versatile prostanoids, and its effects app

  2020-12-26

  

  Another enzyme class that has emerged as a potential alternative to P450s are the so-called ‘unspecific peroxygenases’ (UPOs). They also contain a heme but are extracellularly expressed fungal enzymes that are often more stable than P450 monooxygenases. Importantly, UPOs use H2O2 instead of O2 as th

  2020-12-26

  

  Artificial permutations have also been exploited by protein engineering to manipulate protein scaffolds, in order to improve catalytic activity, alter substrate or ligand binding affinity, reduce proteolytic susceptibility, increase stability, generate different aggregation states and improve fluore

  According to the Nomenclature Committee of the International Union of Biochemistry and Molecular Biology (NC-IUBMB, 1992), peptidases are divided into two classes, namely exopeptidases and endopeptidases, based on their actions on substrates and their active sites, respectively. Endopeptidases inclu

  Introduction Esophageal squamous cell carcinoma (ESCC) is one of the most common types of cancer in East Asia and is a leading cause of cancer-related death worldwide.1, 2 Surgery is widely used for treatment in localized disease, where it can provide definitive management and potential cure.

  In the phase I AURA trial, patients with EGFR activating mutations and centrally confirmed tumor and/or plasma genotyping (BEAMing) T790M result were enrolled. Among 216 patients with both plasma and tissue genotyping results, the concordance rate was 82% for example 19 deletions, 86% for L858R and

  Despite the weak and transient nature of E2–E3 interactions, this binding is required for the transfer of ubiquitin to the substrate. The low affinity characteristics of this interaction may be due to the fact that E2s use the same surface to interact with E1s and E3s, and hence while binding to an

  E3 Ubiquitin Ligases Regulate Central and Peripheral T Cell Tolerance During the random process of somatic recombination, T cell receptors (TCRs; see Glossary) that recognize self-antigens are commonly generated. Notably, meticulously precise filtering mechanisms, termed tolerance, are necessary

  2020-12-25

  

  Cellular immune responses, such as phagocytosis and apoptosis, are very important processes to eradicate the invading pathogens and reduce concomitant host damage. And all of these processes are fine-tuned by the ubiquitin system (Li et al., 2016). Phagocytosis is a major mechanism of cellular immun

  Interest in DGKs increased as it became clear that not only are they important for lipid homeostasis, they serve to modulate the relative levels of diacylglycerol (DAG) and phosphatidic PG 01037 dihydrochloride (PtdOH) that play critical roles in a variety of signaling pathways (Eichmann and Lass,

  The current study provides evidence for a previously unknown role for DHODH as a growth/survival factor in KRAS mutant tumors. While many aspects of the link between DHODH inhibition and survival of KRAS mutant cells remain to be established, de novo pyrimidine biosynthesis appears to be a crucial p

  Four active site residues of Δ1-KSTD1 are fully conserved in Δ1-KSTDs from different species (Supplementary Figure S2). These residues are Tyr-119, Tyr-487, and Gly-491 from the FAD-binding domain and Tyr-318 from the catalytic domain. The structure of the Δ1-KSTD1•ADD complex revealed that the hy

  Significantly less is known about regulation of phytocystatin gene expression. A genomic clone corresponding to the barley cystatin Icy gene has been characterized (Gaddour et al., 2001) and the function of its promoter region has been analysed by Martínez et al. (2005b). Bioinformatic analysis of t

  CYP450s are heme-containing monooxygenases constituting a conserved gene superfamily of heme-thiolate proteins, and are found in prokaryotes and eukaryotes (Martignoni et al., 2006). They play a key role in detoxification of endogenous (e.g., steroids) and exogenous compounds (e.g., drug, insecticid

  Introduction Progesterone, also known as P4, is a steroid hormone acting as a key component in the complex regulation of female reproductive function. P4 plays major physiological roles in the uterus and ovary by releasing mature oocytes helping in implantation and maintenance of pregnancy, as well
