Description
The cricket Gryllus veletis is an emerging model for freeze-tolerance, being able to withstand internal ice formation. When freezing, ice crystals form extracellularly around cells preventing gases from entering. Upon thawing, oxygen can then flood into the cell, most likely increasing the production of Reactive Oxygen Species (ROS) which can cause oxidative stress. Post-thawing crickets can repair the oxidative stress with the help of different antioxidants. For Zainab and I’s research project, we explored oxidative stress in G. veletis during freezing-thawing and post-thawing. In this short series of videos done in partnership with Zainab, I will briefly go over our experimental design, methods and hypotheses.
