The use of a temperature switch to control the growth and productivity of temperature-sensitive (ts) mutants was investigated to extend the productive life span of recombinant Chinese hamster ovary (CHO) cells in batch culture. Bromodeoxyuridine was used at 39ยฐC to select mutagenized CHO-K1 cells, w

โฆ Synopsis
The effect of heat-shock on cell growth and the induction of recombinant protein synthesis by a temperature-sensitive (ts) Chinese hamster ovary (CHO). cell line was investigated. An optimal regime of successive 2 hour heat-shocks (42ยฐC) over 72 hours was found to simultaneously arrest cell growth and induce the synthesis of recombinant protein. The enhanced induction achieved from growth arrested cells may find application in the production of cytotoxic proteins.

Cellular prion protein (PrP(C)) expression can be regulated by heat-shock stress, and we designed the present study to determine whether hypoglycemia could affect PrP(C) expression. RT-PCR and Western blotting were used to measure the expression of PrP(C) and heat-shock protein (Hsp70) in mouse neur
