The gene TP53 (also known as protein 53 or tumor protein 53), encoding transcription factor P53, is mutated or deleted in half of human cancers, demonstrating the crucial role of P53 in tumor suppression. There are reports of nearly 250 independent germ line TP53 mutations in over 100 publications. The P53 protein has the structure of a transcription factor and, is made up of several domains. T...

Differentiation is an epigenetic process which is installed by changes of transcriptional programs over successive cellular divisions. A number of studies have reported the effects of biochemical modifications of chromatin (DNA and chromatin proteins) on the regulation of transcription. Although, these studies are able to explain how transcription of a given gene is regulated (toward activation...

Candida albicans has the ability to change between yeast and hyphal cells and is known to be a virulence property. Efg1gene of C.albicans is as a main transcription factor that plays pivotal roles in biofilm formation The aim of the current study is to investigate the presence of Efg1 gene in Candida albicans isolates from women with vaginal candidiasis and its impact on biofilm formation.We us...

Trypanosoma brucei and the other members of the trypanosomatid family of parasitic protozoa, contain an unusual RNA polymerase II enzyme, uncoordinated mRNA 5' capping and transcription initiation events, and most likely contain an abridged set of transcription factors. Pre-mRNA start sites remain elusive. In addition, two important life cycle stage-specific mRNAs are transcribed by RNA polymer...

Several lines of evidence suggest that some neurotoxicity in AD is due to proteolytic fragments of APP. In this study, we compared the potency of neurotoxicity induced by CT with that of A-beta neurotoxicity and our results showed that various CT peptide fragments (CTFs; CTF99, AICD, CTF31) caused neurotoxicity in cultured cells and primary cortical neurons, induced strong non-selective inward ...

Objective(s):Eukaryotic translation initiation factor 4E (eIF4E) is overexpressed in cervical cancer (CC). However, the molecular mechanisms are unclear. This study aimed to investigate the molecular mechanism of eIF4E gene overexpression in CC. Materials andMethods:The human papillomavirus (HPV) type 18 E7 and eIF4E mRNAs were measured following knock down or overexpression of E7 gene by RT-P...
