Insulin production in pancreatic beta cells is predominantly regulated through glucose control of proinsulin translation. Previously, this was shown to require sequences within the untranslated regions (UTRs) of the preproinsulin (ppI) mRNA. Here, those sequences were found to be sufficient for specific glucose-regulated proinsulin translation. Furthermore, an element 40-48 bp from the 5' end o...

The mouse steroid 16n-hydroxylase (C-P450& family consists of structurally similar genes with very divergent expressions (Wong, G., Itakura, T., Kawajiri, K., Skow, L., and Negishi, M. (1989) J. Biol. Chem. 264,2920-292’7). Of five family members, the C-P4501e, gene exhibits a male-specific expression whereas the P450cb gene is equally expressed in both males and females although the level of e...

Lhx8 (LIM homeobox 8) gene encodes a LIM homeodomain transcriptional regulator that is preferentially expressed in germ cells and critical for mammalian folliculogenesis. However, Lhx8 DNA binding sequences are not characterized yet. We aimed to identify and characterize a cis-acting sequence of germ-cell specific transcriptional factor, Lhx8. To identify Lhx8 DNA binding element, Cyclic Amplif...

amorpha-4, 11-diene synthase (ads) gene is the first and important gene in artemisinin biosynthesis pathway that why for many researchers, the study of how to regulate of this gene is important. transcription factors can change the expression rate of several genes simultaneously. in this study, six wild accessions of artemisia annua, collected from golestan province, were used. many known trans...

In French bean, the glycine-rich cell wall protein GRP 1.8 is specifically synthesized in the vascular tissue. To identify cis-acting sequences required for cell type-specific synthesis of GRP 1.8, expression patterns of fusion gene constructs were analyzed in transgenic tobacco. In these constructs, the uidA (beta-glucuronidase) gene was placed under control of 5' upstream deletions as well as...
