Dopaminergic drug-induced modulation of the expression of the dopamine transporter in peripheral blood lymphocytes in Parkinson's disease.
Journal Title: Pharmacological Reports - Year 2011, Vol 63, Issue 4
Abstract
The modulation of expression of the dopamine transporter by dopaminergic drugs was investigated by flow cytometry in peripheral blood lymphocytes from patients suffering Parkinson's disease. An 8-week in vivo exposure to pramipexole (0.7 mg free base, 3 times a day) or ropinirole (12 mg, once daily), but not levodopa/carbidopa (100/25 mg, 3 times a day), significantly reduced the mean fluorescence intensity of the dopamine transporter in peripheral blood lymphocytes. These results demonstrate that levodopa differs from dopamine agonists in its regulation of dopamine transporter expression in peripheral blood lymphocytes.

Combinatory effects of PBDEs and 17β-estradiol on MCF-7 cell proliferation and apoptosis.
In the present work, we analyzed whether polybrominated diphenyl ethers (PBDEs) (47, 99, 100 and 209) interfere with the effect of 17β-estradiol on the proliferation and apoptosis of the MCF-7 cell line. MCF-7 cells were...
