Awesome news article from the CSB department at UofT highlighting a recent PNAS paper from the Chang lab, featuring the work of former PhD student Sarah Dungan! Many cetacean species can dive to extraordinary depths on a single breath, but … Continue reading →

Great article from UTSC covering the incredible work Alex Van Nynatten, a postdoc in the Lovejoy lab, has been doing with the Deepwater Sculpin in collaboration with the Chang lab! This fish is quite impressive as they are known to … Continue reading →

The ability to generate and detect electric fields is vital for the survival of several groups of fishes. Authors Ahmed A. Elbassiouny, Nathan R. Lovejoy and Belinda S.W. Chang speculated that electric fish may be able to meet the high … Continue reading →

Pathogenic mutations cause rhodopsin to misfold and disrupt its function. In this study, a yeast-based assay was used to screen for compounds that have the potential to rescue the function of mutant rhodopsin. It was confirmed that 9-cis retinal could … Continue reading →

A recent study by Ryan K. Schott, Nihar Bhattacharyya, and Belinda S.W. Chang analysed the patterns of evolution in the gecko phototransduction gene and compared them to those of other reptiles. Parallel shifts in selective constraint on phototransduction genes were … Continue reading →

What do visual disease in humans and dim-light adaptation in fishes have in common? Read our publication on Proceedings of the Royal Society B, and find out more!

In this new assay, light dependent activation of the human rhodopsin protein initiates the yeast mating pathway and results in the signaling of a fluorescent reporter. This innovative technique allowed the authors to characterize a panel of known rhodopsin mutations … Continue reading →
