RESUMEN
Background: Youth and parent engagement is a key component of clinical research. There are many ways to actively and meaningfully engage youth and parents as integral members of research teams, for example, through ad-hoc committees, advisory councils, or as co-leads on projects. When youth and parents are actively and meaningfully engaged in research projects, they share knowledge from their lived experiences to improve the quality and relevance of research. Methods: We describe a case-based example of engaging youth and parent research partners when co-designing a questionnaire to assess preferences for pediatric headache treatments, from both a researcher and youth/parent perspective. We also summarize best practices in patient and family engagement from the literature and pertinent guidelines to assist researchers with integrating patient and family engagement into their studies. Results: As researchers, we felt that the integration of a youth and parent engagement plan into our study significantly altered and strengthened questionnaire content validity. We encountered challenges throughout the process and detailed these experiences to help educate others about challenge mitigation and best practices in youth and parent engagement. As youth and parent partners, we felt that engaging in the process of questionnaire development was an exciting and empowering opportunity, and that our feedback was valued and integrated. Conclusions: By sharing our experience, we hope to catalyze thought and discussion around the importance of youth and parent engagement in pediatric research, with the goal of stimulating more appropriate, relevant, and high-quality pediatric research and clinical care in the future.
RESUMEN
During animal development, transcription factor activities are modulated by several means, including subcellular localization. The Hox cofactor Extradenticle (Exd) has a dynamic subcellular localization, such that Exd is cytoplasmic by default, but is nuclear when complexed with another homeodomain protein, Homothorax (Hth). These observations raise the question of whether dimerization with Hth simply induces Exd's nuclear localization or, alternatively, if Hth is also necessary for Exd activity. To address this question, we analyzed the nuclear transport signals in Exd, including a divergent nuclear export signal (NES) and two nuclear localization signals (NLSs). We show that, although these signals are weak compared to canonical signals, they balance each other in Exd. We also provide evidence that Exd contains an NLS mask that contributes to its cytoplasmic localization. With these signals characterized, we generated forms of Exd that are nuclear localized in the absence of Hth. Surprisingly, although these Exd forms are functional, they do not phenocopy Hth overexpression. These findings suggest that Hth is required for Exd activity, not simply for inducing its nuclear localization.
