The contribution of the post-irradiation changes in prostaglandin transformation to the biochemical mechanism of interphase death of irradiated cells is estimated. It is supposed that prostaglandins are secondary trigger-effectors which initiate the development of primary biochemical reactions giving rise to radiation sickness. It is suggested that the biochemical mechanism of interphase death is complex and involves several concurrent trigger mechanisms including prostaglandin regulation system.

UI MeSH Term Description Entries
D007399 Interphase The interval between two successive CELL DIVISIONS during which the CHROMOSOMES are not individually distinguishable. It is composed of the G phases (G1 PHASE; G0 PHASE; G2 PHASE) and S PHASE (when DNA replication occurs). Interphases
