The Function Of Ecdysone And Inhibiting Programmed Cell Death In Death Class Iii Neurons Of Drosophila Melanogaster, Nikolas Richard Likourentzos Apr 2019

The Function Of Ecdysone And Inhibiting Programmed Cell Death In Death Class Iii Neurons Of Drosophila Melanogaster, Nikolas Richard Likourentzos

EURēCA: Exhibition of Undergraduate Research and Creative Achievement

The inhibition of programmed cell death is a factor believed to be responsible for the survival of cancer cells. Using Drosophila as models, factors contributing to the process of programmed cell death can be studied. Neurons die throughout Drosophila melanogaster development to allow the addition of new neurons. The groups of neurons programmed to die are Death Class I neurons, Death Class II neurons, and Death Class III neurons. Ecdysone is a hormone responsible for the timing of programmed cell death (PCD) in the Death Class neurons. Elevated levels of ecdysone are associated with the initiation of PCD of Death …


Hexavalent Chromium: Elucidating Its Carcinogenic Mechanism, And Testing Potential Preventative Treatments, Ryan Himes, Timothy Mayotte Apr 2019

Hexavalent Chromium: Elucidating Its Carcinogenic Mechanism, And Testing Potential Preventative Treatments, Ryan Himes, Timothy Mayotte

Scholar Week 2016 - present

Cr(VI) (hexavalent chromium) has recently been found in the drinking water of over 250 million Americans. It is a powerful oxidizing agent, and is known to cause cancer, although the specific mechanism has yet to be elucidated. There is no known preventative treatment for Cr(VI) exposure, and the US EPA is currently determining what concentration of Cr(VI) in drinking water can be safely tolerated. This study sought to test the hypothesis that Cr(VI) cytotoxicity can be prevented by various antioxidants. We tested this hypothesis by exposing human embryonic kidney and human intestinal epithelial cells to Cr(VI), with and without the …


Alpha Mangostin As A Chemoprotective Agent Via Activation Of The P53 Pathway For Breast Cancer, Vanessa Van Oost Apr 2019

Alpha Mangostin As A Chemoprotective Agent Via Activation Of The P53 Pathway For Breast Cancer, Vanessa Van Oost

Scholar Week 2016 - present

Breast carcinoma is the most frequently diagnosed cancer among women and causes over 400,000 deaths yearly worldwide. Current treatments such as chemotherapy are not selective for cancerous tissues but are destructive to normal tissues as well. This causes a range of side effects including pain, nausea, hair loss, weakness, and more. Inactivation of p53 is an almost universal mutation within human cancer cells. The ability to activate the p53 pathway which protects cells from tumor formation is lost in 50% of cancers. Due to the prevalence of this mutation, p53 is a uniquely valuable target for applied research. Alpha mangostin …


Exploring The Ipf Lung Through The Lens Of Single Cell Rna Sequencing, Taylor Adams, Jonas Schupp Jan 2019

Exploring The Ipf Lung Through The Lens Of Single Cell Rna Sequencing, Taylor Adams, Jonas Schupp

Yale Day of Data

This poster illustrates the differences between the IPF disease-specific variety of lung macrophages and the two varieties of macrophages known to reside in the normal human lung.
