2,4,5-Trichlorophenoxyacetic acid inhibits apoptosis in PC12 cells.
Life Sciences(2001)
摘要
2,4,5-Trichlorophenoxyacetic acid (2,4,5-T) is an endocrine disrupter that exerts cytotoxic effects on organisms. In this study, the influence of 2,4,5-T at low concentrations on apoptosis in PC12 cells was investigated. Although no apoptotic features were observed in PC12 cells treated with 2,4,5-T, it inhibited the DNA fragmentation induced by serum deprivation. In addition, the cell viability of PC12 cells increased after treatment with 2,4,5-T. In conclusion, 2,4,5-T suppressed the apoptosis of the cultured cells. Since apoptosis is a morphological and biochemical description of a physiological mechanism of cell death that is commonly associated with programmed events necessary for development of individuals and organs, the inhibitory effect of 2,4,5-T on apoptosis might cause serious damage to cell homeostasis and differentiation.
