ABSTRACT
Radiation exposure in utero is known to lead to serious concerns to both the mother and children, including developmental anomalies in the children. In the recent past, trichostatin A, an HDAC (histone deacetylase) inhibitor and epigenetic modifier, has been shown to mitigate radiation-induced anomalies in the male reproductive system of C57BL/6 mice. Therefore, the current study was undertaken to evaluate the mitigating effects of trichostatin A (TSA) against radiation-induced developmental anomalies in mice. Foetuses of in utero whole-body gamma-irradiated mice during the active organogenesis period were examined for developmental anomalies at 8.5 and 18.5 days of gestation. In utero radiation exposure caused developmental anomalies like microcephaly, microphthalmia, gastroschisis and kinky tail besides prenatal mortality. TSA administration post-irradiation was observed to reduce 50% of prenatal mortality at E18.5 by reducing congenital and developmental anomalies. Observation of such results could be corroborated with the HDAC inhibitory potential of TSA knowing that developmental anomalies may have epigenetic origin. TSA, therefore, can be considered as a potential radiomitigator.
