The membrane structure of inner ear protein prestin is revealed

Force spectroscopy of prestin, the motor protein in the inner ear. Credit: Kanazawa University As mammals, we have very sensitive hearing, thanks to a process known as cochlear amplification. This amplification is down to sensory cells in the inner ear called outer hair cells (OHCs), and it is thought to…

Low Glucose Cultivation of CHO cells by Advanced Control System,BR1000

Overview Low glucose cell cultivation (eg. ~1 g/L) for biopharmaceutical production requires frequent sampling and frequent glucose supplementation. The excessive sampling requirement not only reduces the volume of the culture medium, but also is an unnecessary burden on the operators when performed manually. Here, we demonstrated that the Advanced Control…

Dominant expression of multiple drug resistance after in vitro X-irradiation exposure in intraspecific Chinese hamster ovary hybrid cells | Health & Environmental Research Online (HERO)

BACKGROUND: Exposure of Chinese hamster ovary (CHO) cells to fractionated x irradiation in vitro has led to expression of a distinctive multiple-drug-resistant phenotype. This phenotype is characterized by overexpression of P-glycoprotein without an increase in P-glycoprotein messenger RNA or gene amplification; increased glutathione S-transferase (GST) activity; and resistance to vincristine,…

Identification of estrogen receptor beta expression in Chinese hamster ovary (CHO) cells and comparison of estrogen-responsive gene transcription in cells adapted to serum-free media

doi.org/10.1016/S0960-0760(03)00250-4Get rights and content Abstract Most cultured cell lines require addition of serum to the medium to maintain their proliferative capacity. For studies examining the cellular effects of estrogens serum is charcoal-stripped to remove steroids. Nonetheless, addition of the selective estrogen receptor modulator (SERM) 4-hydroxytamoxifen (4-OHT) inhibits the basal transcriptional…
