Parkinson's disease (PD) is a neurodegenerative disorder characterized by progressive death of dopaminergic neurons in the substantia nigra pars compacta (SNpc).
OBJECTIVE
To study if tenuigenin (TEN), the main active component of Polygala tenuifolia, can protect dopaminergic neurons from
One purified polysaccharide protein tyrosine phosphatase (PTP) was isolated from the roots of Polygala tenuifolia. The aim of the present study is to investigate the antitumor effect of PTP on human ovarian cancer OVCAR-3 cells and explore the molecular mechanism of the action involved. The results
Tenuigenin, an active component of Polygala tenuifolia root extracts, has been shown to provide antioxidative and anti-aging effects in Alzheimer's disease, as well as to promote proliferation and differentiation of neural progenitor cells. However, the effects of tenuigenin on Parkinson's disease
