  Nearly 60years ago, the first two estrogen receptor antagonist which catalyze the phosphorylation of proteins were discovered [1]. Protein phosphorylation was originally identified as a regulatory mechanism for the control of glycogen metabolism. Today it is clear that protein phosphorylation regula

  In the course of this study, K+PFOS did not appear to have any effect on the thyroid parameters evaluated (H&E histology, follicular epithelial cell proliferation, and follicular epithelial apoptosis). This is an interesting observation considering the fact that treatment with K+PFOS resulted in act

  RING-type E3s and their substrates There is enormous diversity in substrate ubiquitination and its regulation, as the targets of RING-type E3s are incredibly varied. RING-type E3s are implicated as tumor suppressors, oncogenes, and mediators of endocytosis, and play critical roles in complex mult

  Primases are classified into two major groups: first, the DnaG primases, found in bacteria and bacteriophages, and second, the archaeoeukaryotic primases. Remarkably, bacterial and archaeoeukaryotic primases have no structural similarity and, presumably, evolved independently (Leipe et al., 1999). T

  Introduction Hematopoietic stem 2-NBDG (HSCs) in the adult bone marrow (BM) provide all types of blood cells throughout life, while also self-renewing to maintain blood homeostasis. Blood/marrow stem cell transplantation is the most advanced method to cure patients suffering from hematological mal

  Generally, glycines (and other small residues such as alanine) present in a helical GxxxG-motif that are facing the same side of the helix form a uniform surface that enables direct contact with a second helix. Crystal structures of multipass membrane proteins have demonstrated that GxxxG-motifs are

  HvPap-1, a member of the cathepsin F-like family, was identified in germinating barley seeds (Sreenivasulu et al., 2008). This enzyme participates in the mobilization of stored proteins (mainly hordeins) during the last phase of grain germination, and its activity is modulated by a propeptide or/and

  Genes involved in oxysterol metabolism The main enzymes that participate in the metabolism of oxysterols generally belong into one of two groups: transferases or oxidoreductases [22]. The following chapter describes those genes of oxysterol metabolism whose polymorphisms have been associated with

  An important role for the precursor molecule of the main EBI2 ligand, 25-OHC, in the inhibition of inflammation was recently shown. 25-OHC was demonstrated to inhibit inflammasome induction in mouse macrophages [28]. Inflammasome assemblies are the sites of caspase 1 activation and lead to the gener

  Enzymatic assay. The usual in vitro test for the measure of the activity of DbH involves ascorbate as a cosubstrate (e.g., 5mM) and tyramine as a substrate (e.g., 10mM). When using N-aryl-N′-hydroxyguanidines instead of ascorbate, the hydroxylase activity of DbH was measured by HPLC as the amounts
