Background: Several lines of evidence suggest that oxidized LDL (Ox-LDL) scavenger receptors play a crucial role in the genesis and progression of diabetic atherosclerosis. This study aimed to elucidate the effect of vitamin D3 on gene expression of lectin-like oxidized LDL receptor-1 (LOX-1), scavenger receptor-A (SR-A), Cluster of Differentiation 36 (CD36), and Cluster of Differentiation 68 (...

We found with IM-9 human cultured lymphocytes, that the glucocorticoid dexamethasone increased insulin-receptor mRNA levels. This increase correlated in a time- and dose-dependent manner with the increase in the biosynthesis of the insulin-receptor precursor. In addition, in AR42J cultured rat pancreatic acinar cells, dexamethasone increased insulin-receptor mRNA levels. These studies suggest, ...

objective: estrogen receptor alpha protein status is determined by routine immunohistochemistry analysis in all malignant breast tumors. this assay has its limitations. rna based techniques are potential complements for immunohistochemistry but it must be noticed that gene silencing may occur at different levels from rna to protein. the aim of this study was the comparison of the results from t...

The distribution of mRNA coding for the D2 dopamine receptor was studied in the rat brain by in situ hybridization. A cDNA probe corresponding to the putative third cytosolic loop and sixth and seventh transmembrane domains of the rat D2 receptor was used to generate an 35S-labeled riboprobe to hybridize to D2 receptor mRNA. D2 mRNA was found both in dopamine projection fields and in regions as...

The present study was conducted to quantify and compare TLR2 (toll-like receptor 2) activity in monocyte-derived macrophages of zebu (Tharparkar) and crossbred (Holstein-Friesian × Jersey × Brown Swiss × Hariana) cattle. The cells were either induced with Pam3CSK4 or kept as control. The TLR2 activity was quantified in terms of IκB-α inhibitory subunit (NFKBIA) messenger RNA (mRNA) copies...

Introduction: The G-protein coupled receptor 30 (GPR30) gene is a member of the G-protein coupled receptor (GPCR) family; involved in breast, endometrial, and ovarian cancers. Many GPCR receptors that are implicated in several types of human cancers are correlated with increased cell proliferation and tumor progression; especially GPR30 gene. Methods: The breast cancer MCF-7 and MDA-MB-231 cel...

We used a human platelet alpha 2-adrenergic receptor probe to study the tissue distribution and messenger RNA (mRNA) forms of the rat alpha 2-adrenergic receptor. Under stringent conditions of hybridization and washing, we detected an mRNA species of 3.8 kb. The abundance of this form follows the order spleen, kidney, brain stem and cortex, and skeletal muscle and lung and is consistent with th...

Identification of the D, receptor The D4 receptor was fit identified, using molecular biological techniques, from human’ and from rat2 and shown to be a member of the family of G protein-coupled dopamine receptors. It has substantial homology with Dz and DJ receptors (and is a member of the D,-like receptor subfamily) but its distribution and pharmacological properties are different from either...

Hypertension-associated growth of vascular smooth muscle cells might be mediated in vivo by platelet-derived growth factor (PDGF). Our previous investigations in hypertensive rats failed to demonstrate changes in aortic steady-state mRNA levels of PDGF A or B chains. The current studies were performed to determine whether hypertension might affect the expression of PDGF receptors. We studied PD...

Diversity of cell lineages within glandular organs is generated postnatally by differentiation of committed progenitor cells. Fundamental regulatory aspects of this process are not understood. The mouse submandibular salivary gland (SSG) served as model to assess the role of epidermal growth factor (EGF) receptor signaling during emergence of cell lineage diversity. Temporal fluctuations in EGF...
