Chemical genetics reveals a complex functional ground state of neural stem cells.

Nat. Chem. Biol. 3(5) , 268-273, (2007)

The identification of self-renewing and multipotent neural stem cells (NSCs) in the mammalian brain holds promise for the treatment of neurological diseases and has yielded new insight into brain canc...

Defects in mitochondrial efficiency and H2O2 emissions in obese women are restored to a lean phenotype with aerobic exercise training.

Diabetes 64 , 2104-15, (2015)

The notion that mitochondria contribute to obesity-induced insulin resistance is highly debated. Therefore, we determined whether obese (BMI 33 kg/m(2)), insulin-resistant women with polycystic ovary ...
