Uncovering Novel Small Regulatory Rna In Protostome, Sweta Khanal
Uncovering Novel Small Regulatory Rna In Protostome, Sweta Khanal
Dissertations
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 …
Impacts Of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (Cyprinodon Variegatus) Under Different Environmental Factors, Danielle Simning
Impacts Of Oil Exposure During Early Life Development Stages In Sheepshead Minnows (Cyprinodon Variegatus) Under Different Environmental Factors, Danielle Simning
Master's Theses
The release of approximately 5 million barrels of crude oil into the northern Gulf of Mexico during the 2010 Deepwater Horizon oil spill jeopardized estuarine ecosystem health from Texas to Florida. These estuarine habitats, which serve as nurseries for many important fisheries are also prone to rapid fluctuations in environmental stressors such as oxygen concentration, and salinity. The consequence of combined exposure to crude oil and suboptimal environmental factors during early life stage development of fish is still largely unknown. The objective of this project was to investigate the impacts of exposure to crude oil in combination with varying environmental …
The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones
The Ontogeny Of Whistle Production In Infant Atlantic Bottlenose Dolphins (Tursiops Truncatus) During The First Thirty Days Of Life, Brittany Leigh Jones
Master's Theses
The manner in which dolphin calves acquire their whistle repertoire is largely unknown. This paper focuses on whistle development in four bottlenose dolphin calves during the first thirty days of life in order to increase our understanding of the early emergence of whistles and whistle-like vocalizations. The acoustic parameters of whistle-type vocalizations (i.e., whistles and whistlesquawks) that coincided with a bubblestream emission from the focal calf and/or its mother were analyzed, as were the behavioral states of the mother-calf pair during the emission of such vocals. Mother and calf whistle rates are inversely related, with the mother whistling more often …
