Divergent modulation of neuronal differentiation by caspase-2 and -9.

Human Ntera2/cl.D1 (NT2) cells treated with retinoic acid (RA) differentiate towards a well characterized neuronal phenotype sharing many features with human fetal neurons. In view of the emerging role of caspases in murine stem cell/neural precursor differentiation, caspases activity was evaluated during RA differentiation.

Differentiation-dependent progesterone synthesis and metabolism in NT2-N human neurons.

Human embryonic teratocarcinoma-derived Ntera2/cl.D1 (NT2) cells recapitulate many features of embryonic neuronal progenitor cells. Upon retinoic acid (RA) treatment they terminally differentiate into post-mitotic neuron-like cells (NT2-N), akin to human fetal neurons, thus representing an in vitro model of human neuron terminal differentiation.

Case-control and family-based association studies of candidate genes in autistic disorder and its endophenotypes: TPH2 and GLO1.

Background: The TPH2 gene encodes the enzyme responsible for serotonin (5-HT) synthesis in the Central Nervous System (CNS). Stereotypic and repetitive behaviors are influenced by 5-HT, and initial studies report an association of TPH2 alleles with childhood-onset obsessive-compulsive disorder (OCD) and with autism. GLO1 encodes glyoxalase I, the enzyme which detoxifies alpha-oxoaldehydes such as methylglyoxal in all living cells.
