  Another question concerns the mechanism of PC reduction during the phosphate starvation response. There are at least three main mechanisms of PC depletion: suppression of PC synthesis due to substrate exhaustion, downregulation of PC synthase expression by suppression of gene transcription or intens

  Measurement of Chol absorption, synthesis and catabolism would be very helpful to determine the underlying cause of hypercholesterolemia in individual patients at risk for atherosclerosis. The information could help to determine the best therapeutic approach to reduce Chol absorption, to reduce Chol

  In addition to playing important roles in the immune system, EBI2 is also expressed in the MHC class II antigen (45-57) [Homo sapiens] synthesis of the central nervous system (CNS), namely astrocytes, and this receptor regulates astrocyte signalling, as well as astrocyte cell migration (Rutkowska e

  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

  The best-characterized APC/C substrates are recruited via various linear motifs (e.g., D boxes, KEN boxes, and ABBA motifs) that serve as degrons, binding to distinct regions of the β-propeller domain of a coactivator (Figure 1, Figure 3B) (reviewed in [44]). In addition, D boxes also simultaneously

  The modification of proteins with the small 76-amino imidazoline receptors protein ubiquitin (Ub) plays a central role in many key cellular processes. Ubiquitylation of a target protein requires the concerted action of a cascade of three enzymes (Figure 1). The ubiquitin-activating enzyme (E1) cata

  An important question is to what extent any differences in radioligand characteristics may have contributed to discrepancies between studies. Two studies on schizophrenia addressed this question directly by using [11C]SCH 23390 and [11C]NCC 112 in the same individuals, not finding any differences be

  Introduction The Discoidin Domain Receptors (DDRs), comprising DDR1 and DDR2, are collagen-binding receptor tyrosine kinases (RTKs) that function as microenvironmental sensors at the interface of the extracellular matrix and the intracellular signal transduction machinery [1]. In response to ligand

  Palliative surgeries for refractory epilepsy include vagus nerve stimulation and corpus callosotomy. Among 220 individuals with CDD with parent-entered data, 17% had a vagus nerve stimulation implanted and 69% of parents reported reduced seizure frequency. These data are consistent with a case repor

  Prenylation may turn a flavonoid from an agonist to an antagonist and improve the selectivity to both ERs depending on the position of the substitution. C-8 prenylation appears to promote antagonism to a larger extent than C-6 in ERα due to steric hindrance against generation of agonistic conformati

  In mammals, ribonucleotide reductase (RNR) is a unique enzyme that catalyzes the rate-limiting step of de novo synthesis of deoxyribonucleoside triphosphates (dNTPs).7, 8 Mammalian RNR consists of two homodimer subunits: the large catalytic dimer RRM1 and the small regulatory dimer RRM2 or RRM2B.
