Phenobarbital stimulation of cytochrome P-450 and aminopyrine N-demethylase in hyperplastic liver nodules during LD-ethionine carcinogenesis.

abstract：:Chromosome 22q shows a high frequency of loss of heterozygosity (LOH) in ovarian cancers suggesting the existence of one or more important tumor suppressor genes (TSGs). The tissue inhibitor of metalloproteinase-3 (TIMP-3) is a plausible TSG candidate since it is often encompassed within these regions of LOH. TIMP-3 h...
