Transmission of acquired metabolic disorders from father to offspring through sperm. Environmental factors such as diet and
stress lead to metabolic changes in the germ line of a father that can be transmitted to the offspring. Epigenetic mechanisms
including DNA methylation, histone modification, small non-coding RNAs such as tsRNAs, piRNAs and miRNAs, and small RNA modification
have been reported. Abbreviations: tsRNAs, tRNA-derived small RNAs; piRNAs, Piwi-interacting RNAs; miRNAs, microRNAs.
