Project Title: Genetic Modification of the Starlet Sea Anemone, Nematostella vectensisA key scientific advance for understanding basic biological processes has been the ability to genetically alter model organisms, such as nematodes, fruit flies, and mice. The phylum Cnidaria includes approximately 10,000, mostly marine, basal organisms, including several that are of commercial importance or are under environmental insult, esp. corals. An emerging model organism for animals in this phylum (corals, anemones, jellyfish, hydra) is the starlet sea anemone Nematostella vectensis. This anemone is convenient because it is small, can be collected from natural estuarine sites, is easily maintained in the lab, has extensive regenerative properties, and has a complete genome sequence and extensive RNA expression data. Nevertheless, molecular genetic approaches to modify gene function are limited in this animal. Thus, a major goal of this project is to develop additional and improved methods for altering and introducing gene function in Nematostella. These techniques will then be used to study signaling pathways (e.g., the NF-κB pathway) and biological functions, and perhaps to develop biosensor or decorative animals. For example, one long-term goal may include developing transgenic N. vectensis as biological sensors for environmental factors such as pH, temperature, and salinity.

Project Title: Mapping Transcriptional Enhancers of Mef2a in Skeletal Muscle Differentiation and RegenerationThere are currently no effective treatments for the various forms of muscular dystrophy. The main form of ‘treatment’ consists mainly of aiding patients in controlling the symptoms that accompany their disease. A promising approach in the treatment of muscular disorders involves repairing or replacing diseased muscle with healthy muscle by means of regeneration. Skeletal muscle is one of the few mammalian tissues that has the capacity to regenerate, with new cells arising from muscle stem cells residing in proximity to mature muscle fibers. While many molecular pathways have been identified that regulate muscle regeneration, our understanding of this process is far from complete. Recently, it has been found that transcription factor MEF2A is a key player in the regulation of skeletal muscle regeneration after injury. Given the importance of MEF2A in muscle regenerations, it is essential to understand the mechanisms by which MEF2A is itself regulated because such information will provide insight into the molecular control of muscle regeneration. Specifically, we propose to investigate the transcriptional regulation of the Mef2a gene since its expression is modulated in skeletal muscle regeneration. Our goal is to identify transcriptional enhancers of Mef2a by performing deletion mutagenesis of the proximal promoter and analyzing the activity of these sequences using reporter assays. Various promoter deletions will be analyzed both in vitro in an established muscle cell line and in vivo using a muscle regeneration model in mice. The minimal cis-acting DNA sequences will then be used to identify upstream transcriptional regulators and signaling pathways that control the expression of Mef2a. Overall, these studies will enable us to develop a more complete understanding of the pathways employed in skeletal muscle regeneration, which may have therapeutic relevance for human muscle degenerative diseases.

The 2012 Beckman Scholars graduated in May 2014.

Alex ValentineAlex Valentine, a Biomedical Engineering major, is working with Dr. Joyce Wong in the Biomedical Engineering Department on the development of a drug delivery technique for the treatment of allergic asthma and atopy. The project seeks to develop an ultrasound-facilitated transdermal antibody delivery method that can be validated in mouse models. This project has potential medical implications in that the specific antibody being used has shown therapeutic benefits for over half of asthma patients who have a particular allergen imbalance.

Alex is currently performing research at Harvard Medical School

Zach ArikiZach Ariki, a Chemistry major, is doing research in the laboratory of Dr. John Porco (Chemistry). The general area of his research is the organic synthesis of natural product-based compounds that may have medical benefits. Specifically, Zach is investigating the synthesis of a class of compounds called microsphaerins, which have been demonstrated to have antimicrobial activity against methicillin-resistant Staphylococcus aureus (MRSA), which is now a common hospital pathogen for which there are limited therapeutic options. Thus, the development of methods to synthesize microsphaerins could have important benefits for the treatment of patients with MRSA.

Zach is currently performing research at the Institute of Transformative Biomolecules in Nagoya, Japan.

 

The 2011 Beckman Scholars graduated in May 2013.

claire schenkelClaire Schenkel, who double majored in Biology (Specialization in Cell Biology,Molecular Biolgy & Genetics) and Speech, Language & Hearing Science, performed research with Dr. Kim McCall (Biology). Claire research focussed on the role of programmed cell death in the ovary using the model organism the fruitfly Drosophila melanogaster. This work has relevance to understanding reproductive physiology, development and certain disease processes.
Claire is currently a PhD student in a joint MIT/Harvard Program in Speech & Hearing Science Bioscience and Technology.
RishiKRishikesh Kulkarni majored in Biochemistry & Molecular Biology, and performed research with Dr. Sean Elliott in the Chemistry Department. His research conducted biochemical research to understand the role of iron-sulfur clusters in a novel class of proteins called CDGSH proteins. Using computational protein similarity network analysis, Rishi sought to understand the functional and evolutionary relationship between this new class of proteins, some of which appear to play a role in human diabetes.
