BACKGROUND Twist, a transcription factor of the basic helix-loop-helix class, is reported to regulate cancer metastasis. It is known to induce epithelial-mesenchymal transition (EMT). In this study, we evaluated the expression of twist and its effect on cell migration in hepatocellular carcinoma (HCC). METHODS We examined twist expression using(More)
Cytochrome P450 17alpha-hydroxylase (CYP17) is a single gene-encoded protein with two activities: 17alpha-hydroxylase and 17,20-lyase. The two catalytic activities are differentially regulated in health and disease. We took advantage of naturally occurring human mutations to understand the molecular bases of this differential regulation. We identified eight(More)
Parkinson's disease is characterized by selective loss of dopaminergic neurons in the substantia nigra. However, its associated cell death mechanism remains unknown. 1-Methyl-4-phenil-pyridinium (MPP+) and 6-hydroxydopamine (6-OHDA) cause dopaminergic neuronal cell death. Both are widely used to model PD. We investigated the role of a(More)
