We previously demonstrated that 5-aminomidazole-4-carboxamide-1-\u03b2-D-ribofuranoside (AICAR) and exercise, two potent AMPK activators, improve disease features in DM1 mouse skeletal muscles. Here, we employed a combinatorial approach with these AMPK activators and examined their joint impact on disease severity in male and female DM1 mice. Our data reveal that swimming exercise additively enhances the effect of AICAR in mitigating the nuclear accumulation of toxic CUGexp RNA foci. In addition, our findings show a trend towards an enhanced reversal of MBNL1 sequestration and correction in pathogenic alternative splicing events. Our results further demonstrate that the combinatorial impact of exercise and AICAR promotes muscle fiber hypertrophy in DM1 skeletal muscle. Importantly, these improvements occur in a sex-specific manner with greater benefits observed in female DM1 mice. Our findings demonstrate that combining AMPK-activating interventions may prove optimal for rescuing the DM1 muscle phenotype and uncover important sex differences in the response to AMPK-based therapeutic strategies in DM1 mice.<\/jats:p>","DOI":"10.1093\/hmg\/ddac222","type":"journal-article","created":{"date-parts":[[2022,9,1]],"date-time":"2022-09-01T17:40:18Z","timestamp":1662054018000},"page":"551-566","source":"Crossref","is-referenced-by-count":20,"title":["Combinatorial treatment with exercise and AICAR potentiates the rescue of myotonic dystrophy type 1 mouse muscles in a sex-specific manner"],"prefix":"10.1093","volume":"32","author":[{"given":"Naomi S","family":"Misquitta","sequence":"first","affiliation":[{"name":"Department of Cellular and Molecular Medicine , Faculty of Medicine, , Ottawa, ON , Canada"},{"name":"University of Ottawa , Faculty of Medicine, , Ottawa, ON , Canada"},{"name":"The Eric J.
