Abstract

We are studying nucleotide sequences responsible for the regulation of eukaryotic gene expression. Our test system comprises the human genes coding for prolactin (hPRL), growth hormone (hGH-N) and placental lactogen (hCS-B). We have cloned these genes and are searching within their sequences for in vitro binding sites of the human glucocorticoid receptor on the hGH-N and hCS-B genes; the in vivo activity of such DNA sequences by assaying hybrid gene expression in transfected cells; in vivo "enhancer" activity of different hPRL gene fragments linked to a marker gene and transfected in cultured cells.

CREs: Gene & Cell Therapy

Gene and cell therapy advances have shown promising outcomes for several diseases. The role of cis-regulatory elements (CREs) is crucial in the design of gene therapy vectors. Here is the latest research on CREs in gene and cell therapy.
