Sperm Can Pass Trauma Symptoms Through Generations, Study Finds
"Researchers have put ample effort into identifying genes that help explain why cancer or heart disease run in some families."
Implications Of Sperm RNAs In Transgenerational Inheritance Of The Effects Of Early Trauma In Mice
"Small non-coding RNAs (sncRNAs) are potential vectors at the interface between genes and environment. We found that traumatic stress in early life altered mouse microRNA (miRNA) expression, and behavioral and metabolic responses in the progeny. Injection of sperm RNAs from traumatized males into fertilized wild-type oocytes reproduced the behavioral and metabolic alterations in the resulting offspring."
