Background: Tumor necrosis factor- a (TNF-α) is a cytokine that was identified as a factor with a wide range of proinflammatory activities. The expression of bovine TNF-α in mammary tissue during pregnancy seems to have a role in development of the corresponding glands.Objective: Single nucleotide polymorphisms (SNPs) were defined in 3′-flanking region of...

Circular DNA was obtained from human bone marrow. Then a phage library was prepared and screened by use of two probes of the IgH gene; 5'-DHQ52, containing the 5' flanking region of DHQ52, and JH4.3, containing the sequence from JH3 to the 3' flanking region of JH6. One clone, HBMC-1, that was DHQ52+JH4.3- was obtained. HBMC-1 had the germline IgH region upstream of JH1 and the 3' flanking regi...

A genomic clone, encompassing the 5' flanking region and the first seven exons of rat ATP citrate lyase gene, was isolated from a rat genomic library and sequenced. Primer-extension analysis showed that mRNA is transcribed at 4407 nucleotides upstream from the translation start site. Primer-extension analysis and sequencing of ATP citrate lyase cDNA amplified by PCR showed that the promoter use...

To study expression and function of the vimentin gene, transgenic mice were generated by microinjecting the entire chicken gene plus 2.4 kilobases of 5' and 2.6 kilobases of 3' flanking sequences. All the transgenic mice obtained had incorporated multiple copies of the gene. RNA analyses demonstrated that the chicken vimentin gene was efficiently expressed in an appropriate tissue-specific patt...

The rat class 3 aldehyde dehydrogenase gene (ALDH3A1) is expressed constitutively or by xenobiotic induction depending on the tissue in which it occurs. Although the mechanism that mediates inducible expression has been well characterized, relatively little is known about constitutive regulatory mechanisms. Previous ALDH3A1 promoter analyses have indicated that primary regulatory regions within...
