Dopamine beta-hydroxylase, the enzyme which converts dopamine to norepinephrine, is expressed in a cell type-restricted pattern in neuroendocrine tissue. A segment of the rat gene containing 395 bases of 5'-flanking sequence regulates expression of a reporter gene in a cell type-selective pattern in mammalian cell cultures. Using deletion mutants of the 5'-flanking sequence, we have identified ...
bcl-x is a member of the bcl-2 family of genes and by alternative splicing gives rise to two distinct mRNAs: bcl-xL and bcl-xS. We have previously investigated the expression of Bcl-x in neuroblastoma (NB) cell lines and have shown that Bcl-xL is expressed and functions to inhibit chemotherapy-induced apoptosis. However, none of the NB cell lines expressed Bcl-xS. The aim of the present study w...
A number of neural and nonneural tumor cell lines of rat and human origin were assayed for neuron-specific enolase (NSE) by radioimmunoassay. Most neural tumor cell lines had appreciably higher levels of NSE than did the nonneural tumor cell lines, the highest levels being found in two anaplastic rat glioma lines ( F98 and T24). These two lines contained more than twice the amount of NSE found ...
The dynamic regulation of transcriptional events is fundamental to many aspects of neuronal cell functions. However, proteomics methods have not been routinely used in global neuroproteomics analyses of transcriptional regulators because they are much less abundant than the "house-keeping" proteins in cells and tissues. Recent improvements in both biochemical preparations of nuclear proteins an...
Abstract Objectives The current research examines the protective effects of Piper cubeba ethanolic extract and its isolated lignans; Cubebin Hinokinin fractions against Alzheimer’s Disease (AD) in vitro model. Methods Dried powdered fruit P. were extracted ethanol fractionated using silica gel column chromatography. Of 15 eluted fractions, two indicated presence targeted Lignans; Cubebin. They ...
Fatty acid binding proteins (FABPs) are essential for energy production and long-chain polyunsaturated fatty acid-related signaling in the brain and other tissues. Of various FABPs, heart-type fatty acid binding protein (H-FABP, FABP3) is highly expressed in neurons of mature brain and plays a role in arachidonic acid incorporation into brain and heart cells. However, the precise function of H-...
