Transcription of the human urokinase type plasminogen activator (uPA) gene in HeLa cells is induced by phorbol myristate acetate (PMA), interleukin-1 (IL-1) and tumor necrosis factor alpha (TNF alpha). The response to these factors is rapid, independent of new protein synthesis and amplified in the presence of an inhibitor of protein synthesis, indicating the presence of a labile repressor. A D...

The gene that encodes acetyl-coenzyme A carboxylase (ACCase; EC 6.4.1.2) in the eukaryotic alga Cyclotella cryptica has been isolated and cloned, representing the first time that a full-length gene for this enzyme has been isolated from a photosynthetic organism. The gene contains a 447-base pair intron that is located near the putative translation initiation codon and a 73-base pair intron tha...

background rapid dose assessment using biological dosimetry methods is essential to increase the chance of survival of exposed individuals in radiation accidents. objectives we compared the expression levels of the fdxr and rad51 genes at 6 and 18 mv beam energies in human peripheral blood lymphocytes. the results of our study can be used to analyze radiation energy in biological dosimetry. con...

genetic typing methods of t. gondii strains have been extensively perfected in recent years. from a technical point of view, many tools usable for genetic studied on single-copy loci have been used: rflp, pcr-rflp, sequencing, rapd-pcr and isoenzyme analysis. we described the cloning and sequence analysis of the gene which encodes the major surface antigen (sag1 or p30) of t. gondii. sag1 is th...

Stem cell factor (SCF) is a critical protein with key roles in the cell such as hematopoiesis, gametogenesis and melanogenesis. In the present study a comparative analysis on nucleotide sequences of SCF was performed in Humanoids using bioinformatics tools including NCBI-BLAST, MEGA6, and JBrowse. Our analysis of nucleotide sequences to find closely evolved organisms with high similarity by NCB...

Experimental analysis of complex quantitative genetic traits, such as essential hypertension, should be greatly facilitated by being able to manipulate the expression of a gene in living animals without altering the nucleotide sequence, chromosomal location, or regulatory elements of the gene. To explore this possibility, we have used targeted gene disruption and duplication to generate mice th...

Background: Male infertility is a Multifactorial syndrome encompassing a wide variety of disorders. In more than half of infertile men, the cause of their infertility is unknown (idiopathic) and could be congenital or acquired. Globozoospermia, also called round-headed spermatozoa, is a rare disease with incidence< 0.1% among male infertile patients. The most prominent feature of globozoospermi...
