Rnai “Flexon” Approach To Gonad Gene Knockdown In C. Elegans, Sofia Suzanne Douglas
Undergraduate Theses
All living things require some form of genetic regulation so that gene products are correctly produced and maintained. One significant form of post-transcriptional gene expression is RNA silencing, a biological mechanism in which double stranded RNA molecules inhibit gene expression by blocking translation of targeted mRNA molecules. Due to its extensive applications in biotechnology, it’s been adapted as an experimental technique referred to as RNAi. This technique is temporary, transient, and easy to use. A new form of RNAi, referred to as the “Flexon” technique, is a novel approach that provides a method for post-transcriptional gene regulation that allows for …

Small RNAs play pivotal roles in post-transcriptional gene regulation across diverse phylum of protostomes. In this study, we investigate the functional significance of atypical miRNAs, mirtron miR-1017 in Drosophila. Through ectopic expression in neuronal cells, we demonstrate that miR-1017 extends lifespan by targeting its host transcript, acetylcholine receptor Dα2, and influencing its splicing. This novel trans-regulatory function suggests a mechanism for mirtron evolution, highlighting the interplay between splicing and post-transcriptional regulation. Additionally, we profile small RNA populations in the polychaete developmental model Capitella teleta, shedding light on the small RNA landscape in annelid worms. Our analysis reveals a rich …
