Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, Christopher M. Long, Pushpak N. Bhandari, Joseph Irudayaraj
Nanobubbles Provide Theranostic Relief To Cancer Hypoxia, Christopher M. Long, Pushpak N. Bhandari, Joseph Irudayaraj
The Summer Undergraduate Research Fellowship (SURF) Symposium
Hypoxia is a common motif among tumors, contributing to metastasis, angiogenesis, cellular epigenetic abnormality, and resistance to cancer therapy. Hypoxia also plays a pivotal role in oncological studies, where it can be used as a principal target for new anti-cancer therapeutic methods. Oxygen nanobubbles were designed in an effort to target the hypoxic tumor regions, thus interrupting the hypoxia-inducible factor-1α (HIF-1α) regulatory pathway and inhibiting tumor progression. At less than 100nm, oxygen nanobubbles act as a vehicle for site-specific oxygen delivery, while also serving as an ultrasound contrast agent for advanced imaging purposes. Through in vitro and in vivo studies, …
Role Of Sumoylation In Mitochondrial Division In Tetrahymena Thermophila, Ramya Modi, James Forney
Role Of Sumoylation In Mitochondrial Division In Tetrahymena Thermophila, Ramya Modi, James Forney
The Summer Undergraduate Research Fellowship (SURF) Symposium
SUMOylation is a post translation modification that involves the addition of a small protein called SUMO, Small Ubiquitin-like MOdifier to a target protein. It is an important mechanism for the regulation of gene expression, the maintenance of genomic stability and in modifying nuclear proteins. More recently evidence has emerged for its importance in regulating mitochondrial fission and fusion in mammalian cells. This study evaluates the parameters for optimal staining of Tetrahymena thermophila mitochondria using two different dyes and then examines different cell lines with defects in the SUMOylation pathway. The first staining method uses Mitotracker Green, a vital stain that …
