The mitochondrial respiratory chain has been reported to play a role in the stabilization of HIF-1α when mammalian cells experience hypoxia, most likely through the generation of free radicals. Although previous studies have suggested the involvement of superoxide catalyzed by complex III more recent studies raise the possibility that nitric oxide (NO)(More)
Spinal muscular atrophy (SMA), the leading genetic disorder of infant mortality, is caused by low levels of survival motor neuron (SMN) protein. Currently it is not clear how the SMN protein levels are regulated at the post-transcriptional level. In this report, we find that Usp9x, a deubiquitinating enzyme, stably associates with the SMN complex via(More)
Low levels of the survival motor neuron (SMN) protein cause spinal muscular atrophy, the leading genetic disorder for infant mortality. SMN is ubiquitously expressed in various cell types and localizes in both the cytoplasm and the nucleus, where it concentrates in two subnuclear structures termed Cajal body (CB) and gems. In addition, SMN can also be(More)
