Abstract

Myotonic dystrophy type 1 (DM1) is the most common adult muscular dystrophy and presents an autosomal dominant inheritance. A reproductive option for the families affected is preimplantation genetic diagnosis (PGD). One limitation of this option is the nonoptimal response to ovarian stimulation of the women with DM1, although controversial results exist regarding this subject. In this study, we have analyzed the results of the PGD program applied to DM1 at our institution. A total of 35 couples have been included in our program since 2010, and 59 cycles have been performed. The percentage of transfers per cycle was 64.4% and the live birth rate per cycle was 18.6%. Interestingly, statistically significant differences were observed for the clinical results in the group of couples with an affected female versus the group with an affected male or versus a group of couples with different referral reasons. Specifically, both the percentage of mature oocytes out of the total oocytes retrieved and the percentage of fertilization were considerably lower in the group of DM1 females. Our findings would suggest the possibility of achieving less favourable PGD outcomes in women with DM1 in comparison with other pathologies, although the underlying mechanism remains unknown., This work was supported by the Project PI-105-2011, funded by “Fundación Pública Andaluza Progreso y Salud,” within the Regional Ministry of Health of the Autonomous Government of Andalucia.

Abstract

Hirschsprung disease (HSCR, OMIM 142623) is a pathology that shows a lack of enteric ganglia along of the distal gastrointestinal tract. This aganglionosis is attributed to an abnormal proliferation, migration, differentiation and/or survival of enteric precursor cells (EPCs) derived from neural crest cells (NCCs) during the enteric nervous system (ENS) embryogenesis. DNMT3b de novo methyltransferase is associated with NCCs development and has been shown to be implicated in ENS formation as well as in HSCR. In this study we have aimed to elucidate the specific mechanism underlying the DNMT3b role in such processes. We have performed the knockdown of Dnmt3b expression (Dnmt3b-KD) in enteric precursor cells (EPCs) to clarify its role on these cells in vitro. Moreover, we have analyzed several signaling pathways to determine the mechanisms responsible for the effect caused by Dnmt3b-KD in EPCs. Our results seem to support that Dnmt3b-KD promotes an increase EPCs proliferation that may be mediated by P53 and P21 activity, since both proteins were observed to be down-regulated in our Dnmt3b-KD cultures. Moreover, we observed a down-regulation of P53 and P21 in HSCR patients. These results lead us to propose that DNMT3b could be involved in HSCR through P53 and P21 activity., This work was supported by the project “PI16/01422” funded by Instituto de Salud Carlos III and co-funded by European Union (ERDF/ESF, “Investing in your future”) and by the project “CTS-7447” funded by Regional Ministry of Innovation, Science and Enterprise of the Autonomous Government of Andalucia. L V-B is supported by a fellowship associated whit the CTS-7447 project.
