Perplexing peroxisome proliferators.
Soft agarose culture human tumour colony forming assay for drug sensitivity testing: [3H]-Thymidine incorporation vs colony counting Summary In vitro drug sensitivity testing, both by optical colony counting and by a [3H]-TdR incorporation assay, was performed on human tumour cells proliferating in soft agar cultures. Cells from two different human tumour cell lines, 5 different human tumour xe...
متن کاملPeroxisome proliferators activate Kupffer cells in vivo.
The mechanism by which peroxisome proliferators increase cell replication and cause liver tumors in rodents remains unknown. When activated, Kupffer cells, the resident hepatic macrophages, release a variety of mitogenic stimuli that could theoretically increase cell proliferation in nearby hepatocytes. Therefore, in the present study we evaluated the effect of two potent peroxisome proliferato...
متن کاملExposure to peroxisome proliferators: reassessment of the potential carcinogenic hazard.
Melnick (1) recently suggested that because peroxisome proliferation is not established as an obligatory step in the carcinogenicity of peroxisome proliferators (PPs), the proposal that the peroxisome proliferator di(2-ethylhexyl)phthalate (DEHP) poses no carcinogenic risk to humans (2) due to species differences in peroxisome proliferation should be viewed as an unvalidated hypothesis (1). In ...
متن کاملPeroxisome Proliferators-Activated Receptor (PPAR) Modulators and Metabolic Disorders
Overweight and obesity lead to an increased risk for metabolic disorders such as impaired glucose regulation/insulin resistance, dyslipidemia, and hypertension. Several molecular drug targets with potential to prevent or treat metabolic disorders have been revealed. Interestingly, the activation of peroxisome proliferator-activated receptor (PPAR), which belongs to the nuclear receptor superfam...
متن کاملThe effect of peroxisome proliferators on mitochondrial bioenergetics.
Peroxisome proliferators are a group of structurally diverse chemicals that cause the proliferation of peroxisomes in rodents. The purpose of this investigation was to test the hypothesis that the shared effect of these compounds on peroxisome proliferation is mediated through a common inhibitory effect on mitochondrial bioenergetics. Freshly isolated rat liver mitochondria were energized with ...
