    ..In addition, these mice were susceptible to streptozotocin-induced diabetes and endotoxic shock. These data indicate that PARG(110) plays an important role in DNA damage responses and in pathological processes. ..

    ..Our results show that Bax and Bak regulate mitochondrial dynamics in healthy cells and indicate that Bcl-2 family members may also regulate apoptosis through organelle morphogenesis machineries. ..

    The Tim23 protein is the key component of the mitochondrial import machinery. It locates to the inner mitochondrial membrane and its own import is dependent on the DDP1/TIM13 complex...

    ..Loss of Lpp1 function disrupts neurulation by permitting more extensive floor plate induction by Shh, thereby inhibiting midline bending of the neural plate during initiation of neurulation. ..
