Heparg micronucleus

WebMicronucleus induction was seen in cultured meiotic mouse sperm cells at dose levels approaching toxicity, and a rat dominant lethal test was also positive, neither of which is too surprising since male germ cells are among the most sensitive cell targets. Positive results have been reported for strand breaks and DNA degradation in in vitro ... Web1 apr. 2024 · However, currently standardised in vitro methods for genotoxicity testing using mammalian cells (HPRT and TK assays, micronucleus assay) are tedious and not suitable for high-throughput testing. One of the promising markers of DNA damage response for genotoxicity assessment seems to be the phosphorylation of the histone variant H2AX [ 5 ].
