A hypothesis for chemical carcinogen induced chromatin condensation.
A hypothesis for chemical carcinogen induced condensation of nuclear and nucleolar chromatin is proposed. Chromatin condensation is believed to be a result of cascade effects initiated by the inhibition of messenger RNA synthesis after exposure to chemical carcinogen in vivo. Inhibition of messenger RNA synthesis leads to the loss of protein production, which in turn causes the dephosphorylation of histone H1 and triggers the condensation of chromatin in vivo.
