Video of the Month: A cell dividing

When cells divide, they pose significant energy demands. The video this month features the highly dynamic nature of cell division.

The mitochondria, tiny structures inside cells, provide energy for this and other cell functions. In his lab at Baylor College of Medicine, Dr. Ross Poché and his colleagues study the precise requirements for mitochondrial activity in proliferating cells.

“One specific aspect of our research is to determine precisely how mitochondrial activity and other bioenergetic pathways interface with cell cycle progression during development,” Poché said.

Additionally, the Poché lab aims to identify new strategies to promote retinal regeneration in response to photoreceptor damage.

In the lab, they apply a multi-disciplinary approach utilizing genetic loss- and gain-of-function experiments, molecular biology and live retinal confocal microscopy.

Dr. Ross A Poché is an associate professor of molecular physiology and biophysics and a member of the Dan L Duncan Comprehensive Cancer Center.
