Abstract
1. 1. Transcription was carried out in isolated rat liver nuclei by endogenous RNA polymerase with the addition of HeLa whole cell extract (HWCE) in the presence ofnucleoside 5′-[γ-S]triphosphate. 2. 2. The resulting 5′-γ-thiophosphate on the synthesized RNA allows separation of in vitro initiated RNA from bulk RNA by mercury-agarose chromatography. 3. 3. HWCE not only increased initiation of new RNA chains greater than 3 times but also had no effect on the RNA synthesis by RNA polymerase II. 4. 4. The initiation of transcription of albumin and α-fetoprotein genes in an isolated nuclei system was selectively enhanced by HWCE. 5. 5. Using this system, we studied the effect of glucocorticoid on albumin and α-fetoprotein gene expression in vitro.
