Overexpression of AP-2 alpha in BeWo cells led to an increased rate of apoptosis, whereas apoptosis was decreased when AP-2 alpha expression was reduced. Furthermore, overexpression of AP-2 alpha increased Bax expression and decreased Bcl-2
expression, whereas down-regulation of AP-2 alpha expression resulted in a decrease in Bax expression and an increase in Bcl-2 expression. AP-2 alpha regulates expression of Bcl-2 and Bax and apoptosis in BeWo cells. These results suggest that selleck inhibitor AP-2 alpha-mediated regulation of Bcl-2 and Bax regulation influences apoptosis which in turn leads to the pathogenesis of preeclampsia.”
“Upon activation by therapeutics, the nuclear xenobiotic/constitutive active/androstane receptor (CAR) regulates various liver functions Stattic supplier ranging from drug metabolism
and excretion to energy metabolism. CAR can also be a risk factor for developing liver diseases such as hepatocellular carcinoma. Here we have characterized the conserved threonine 38 of human CAR as the primary residue that regulates nuclear translocation and activation of CAR. Protein kinase C phosphorylates threonine 38 located on the alpha-helix spanning from residues 29-42 that constitutes a part of the first zinc finger and continues into the region between the zinc fingers. Molecular dynamics study has revealed that this phosphorylation may destabilize this helix, thereby inactivating CAR binding to DNA as well as sequestering it in the cytoplasm. We have found, in fact, that helix-stabilizing mutations reversed the effects of phosphorylation. Immunohistochemical study using an anti-phosphothreonine 38 peptide antibody has, in
fact, demonstrated that the classic CAR activator phenobarbital dephosphorylates the corresponding threonine 48 of mouse CAR in the cytoplasm of mouse liver and translocates CAR into the nucleus. These results define CAR as a cell signal-regulated constitutive active nuclear receptor. These Napabucasin mw results also provide phosphorylation/dephosphorylation of the threonine as the primary drug target for CAR activation.”
“Background. Schizophrenia patients demonstrate impairment on visual backward masking, a measure of early visual processing. Most visual masking paradigms involve two distinct processes, an early fast-acting component associated with object formation and a later component that acts through object substitution. So far, masking paradigms used in schizophrenia research have been unable to separate these two processes.\n\nMethod. We administered three visual processing paradigms (location masking with forward and backward masking, four-dot backward masking and a cuing task) to 136 patients with schizophrenia or schizoaffective disorder and 79 healthy controls. A psychophysical procedure was used to match subjects on identification of an unmasked target prior to location masking.
