Luteinizing hormone (LH) and insulin stimulate transcriptional activity of the porcine low-density lipoprotein (LDL) receptor (LDLR) promoter supra-additively in primary cultures of granulosa-luteal cells. The mechanistic basis of this bihormonal interaction is unknown. The pig LDLR gene promoter includes three putative Sp1/Sp3-binding sites and one sterol response element (SRE) site 5' upstrea...
The high-affinity receptor for IgG (FcgammaRI) is a myeloid cell-specific and IFN-gamma-induced gene, and thereby serves as a paradigm for cytokine-induced cell type-specific gene responses. The expression of FcgammaRI is regulated by PU.1 and Stat1 transcription factors. We established an experimental model to analyze the individual functions of Stat1 and PU.1 in cytokine-induced transcription...
The elongation of long-chain fatty acid family member 6 (ELOVL6) gene plays an important role in the synthesis saturated and monounsaturated acids. Although some studies have revealed that ELOVL6 is target sterol regulatory element binding protein 1 (SREBP1; name SREBF1) rodents, mechanism underlying regulation during lactation dairy goats remains unknown. present study aimed to investigate tra...
RIO1 is an essential gene that encodes a protein serine kinase and is transcribed constitutively at a very low level. Transcriptional activation of RIO1 dispenses with a canonical TATA box as well as with classical transactivators or specific DNA-binding factors. Instead, a dG-dC-rich sequence element, that is located 40 to 48 bp upstream the single site of mRNA initiation, is essential and pre...
Abstract Background and objective: Hepatitis B virus (HBV) is a DNA virus with high tendency toward hepatic tissue. There are currently about 3 million HBV-infected people and 350 to 400 million chronic carriers of this virus in the world. X protein plays a role in the over-expression of oncogenes, carcinogenicity of liver cells and overlaps with the basal co...
The immediate/early promoter/enhancer of cytomegalovirus (CMV promoter) is one of the most commonly used promoters for expression of transgenes in eukaryotic cells. In practice, the CMV promoter is often thought of as a constitutively active unregulated promoter. However, we have observed that transcription from the CMV promoter can be up-regulated by a variety of environmental stresses. Many f...
Systemically applied Salmonella enterica spp. have been shown to invade and colonize neoplastic tissues where it retards the growth of many tumors. This offers the possibility to use the bacteria as a vehicle for the tumor specific delivery of therapeutic molecules. Specificity of such delivery is solely depending on promoter sequences that control the production of a target molecule. We have e...
