Whitehead Institute researchers reprogrammed human skin cells from Parkinson's disease patients into an embryonic-stem-cell-like state. After removing the reprogramming genes, the scientists used these so-called induced pluripotent stem (iPS) cells to create dopamine-producing neurons, the cell type that degenerates in Parkinson's disease patients.Â To confirm that the iPS cells had become dopam...

The image on the left shows a sample from a normal prostate, with organized cells lining the O-shaped ductules. Â Mice without theÂ PTENÂ gene had developed cancer, which is characterized by enlarged glands and disorganized cells clogging the ductules (middle image). Â When mTORC2 activity is blocked in mice lacking the PTENÂ gene, the prostate ductulesÂ resemble the appearance of norm...

Study links genetic, environmental causes of Parkinson's

February 1, 2009

The Graybiel Lab caused Parkinson's disease in rats by depleting dopamine in the right side of the striatum, the brain region that drives the abnormal movements in the disease, leaving the left side as the control. Treating the rats with L-DOPA induced dyskinesia...

Do-it-yourself biology: Learning to build a better microbe

January 13, 2009

MIT researchers found that mice with normal DNA repair systems had more retinal degeneration upon exposure to environmental toxic agents than mice lacking a certain DNA repair system. At right, the cross section of the retina from a mouse lacking the repair system is normal. At left, mice with too much DNA repair have greatly reduced numbers of cells in the OPL (outer plexiform layer) and ONL (ou...
