targeting human telomerase reverse transcriptase by a simple sirna expression cassette in hepg2 cells
background human telomerase reverse transcriptase (htert) has become an ideal target for development of anticancer therapy. small interfering rnas (sirnas) are very powerful reagents for gene silencing and show promise for cancer gene therapy. however, only a small number of sirnas have been demonstrated to be effective. for gene therapy targeting htert, it is essential to develop a robust syst...
متن کاملExpression of a bovine kappa-CN cDNA in the mammary gland of transgenic mice utilizing a genomic milk protein gene as an expression cassette.
Transgenic mice were produced by microinjection of a DNA construct composed of the bovine kappa-casein (kappa-CN) cDNA under the control of the goat beta-CN 5' promoter elements and 3' flanking regions into pronuclear-stage embryos. The gene construct targeted the expression of bovine kappa-CN RNA to the mammary gland and secretion of bovine kappa-CN in the milk. In the three lines studied (BC-...
متن کاملFGFR-3 and FGFR-4 function cooperatively to direct alveogenesis in the murine lung.
Mammalian lungs begin as an outpocket of the foregut, and depend on multiple stages of branching morphogenesis and alveogenesis to reach their final form. An examination of fgf receptor gene expression indicated that all four receptors (fgfr-1 to fgfr-4) are expressed in postnatal lungs at varying levels. We show that mice homozygous for a targeted mutation of fgfr-4 exhibited no overt abnormal...
متن کاملGene expression in the mammary gland.
We have demonstrated that the ovine genomic clone SS1 can be used to generate transgenic mice that produce significant quantities of BLG protein in milk. The smallest BLG construct so far examined that retains the ability to direct BLG to mouse milk encompasses approximately 7.3 kb of genomic DNA, of which about 0.8 kb is derived from the promoter region. Gene expression is tissue-specific and ...
متن کاملEffects of BRCA1 Transgene Expression on Murine Mammary Gland Development and Mutagen-Induced Mammary Neoplasia
To characterize the role of BRCA1 in mammary gland development and tumor suppression, a transgenic mouse model of BRCA1 overexpression was developed. Using the mouse mammary tumor virus (MMTV) promoter/enhancer, transgenic mice expressing human BRCA1 or select mutant controls were generated. Transgenic animals examined during adolescence were shown to express the human transgene in their mammar...
