Flaxseed oil attenuates PFOS-induced testicular damage by regulating RNA alternative splicing

: This study revealed that FO can alleviate PFOS-induced testicular dysfunction by regulating RNA alternative splicing. The spliceosome-related proteins PRPF3 and PUF60 may be the potential targets for FO to alleviate PFOS-induced testicular injury. FO supplementation may be an effective dietary intervention to prevent adverse effects of PFOS on testes.
