J. Clin. Invest. 99, 1897-1905. Molecular basis of autosomal dominant neurohyposphyseal diabetes insipidus: Cellular toxicity caused by the accumulation of mutant vasopressin precursors within the endoplasmic reticulum. 1997

Ito, M., Jameson, J.L., Ito, M.

Notes: Mutant and wildtype arginine vasopressin (AVP) constructs were co-transfected with a CAT-expression vector containing a neo resistance gene. Stable transformants of Neuro2A cells were generated with the aid of the Transfectam® Reagent and G418 sulfate. CAT activity in stably transfected clones was determined with the CAT Enzyme Assay System. The effect of the mutant AVP constructs on cell viability was determined with the CellTiter 96® AQueous Cell Proliferation Assay (MTS/PMS). Several constructs displayed marked decreases in cell viability. The cause was necrosis rather than apoptosis due to the absence of DNA laddering and a negative reaction in the Apoptosis Detection System, Fluoroscein (data not shown). The name of the Apoptosis Detection System, Fluorescein, has changed to DeadEnd™ Fluorometric TUNEL System. (1009)

J. Pharmacol. Exp. Ther. 283(3), 1520-1528. The protective effect of metallothionein against lipid peroxidation caused by retinoic acid in human breast cancer cells 1997

Hurnanen, D., Chan, H.M., Kubow, S.

Notes: Overexpression of metallothionein (MT) is linked to decreased cancer survival. One hypothesis is that MT protects from retinoic acid (RA) induced cytotoxicity by scavenging free radicals. This study compared cell viability in two breast cancer cell lines that differ in basal MT expression and estrogen receptor expression. Cells were pretreated with zinc to induce MT expression and then treated with RA. Cell viability was determined using the Cell Titer 96® AQueous Non-Radioactive Cell Proliferation Assay. (2482)
