Turmeric (curry powder), an essential ingredient of culinary preparations of Southeast Asia, contains a major polyphenolic compound known as curcumin or diferuloylmethane. Curcumin is a widely studied phytochemical with a variety of biological activities. In addition to its anti-inflammatory and antimicrobial/antiviral properties, curcumin is considered as(More)
Mutations of the PTEN-induced kinase 1 (PINK1) gene are a cause of autosomal recessive Parkinson's disease (PD). This gene encodes a mitochondrial serine/threonine kinase, which is partly localized to mitochondria, and has been shown to play a role in protecting neuronal cells from oxidative stress and cell death, perhaps related to its role in(More)
Mutations in leucine-rich repeat kinase 2 (LRRK2) are a major cause of familial Parkinsonism, and the G2019S mutation of LRRK2 is one of the most prevalent mutations. The deregulation of autophagic processes in nerve cells is thought to be a possible cause of Parkinson’s disease (PD). In this study, we observed that G2019S mutant fibroblasts exhibited(More)
Mitochondria-associated membranes (MAMs) are structures that regulate physiological functions between endoplasmic reticulum (ER) and mitochondria in order to maintain calcium signaling and mitochondrial biogenesis. Several proteins located in MAMs, including those encoded by PARK genes and some of neurodegeneration-related proteins (huntingtin, presenilin,(More)
Fipronil is a phenylpyrazole insecticide known to elicit neurotoxicity via an interaction with ionotropic receptors, namely GABA and glutamate receptors. Recently, we showed that fipronil and other phenylpyrazole compounds trigger cell death in Caco-2 cells. In this study, we investigated the mode of action and the type of cell death induced by fipronil in(More)

We characterized the dynamics of autophagy in vitro using four different cell systems and analyzing markers widely used in this field, i.e. LC3 (microtubule-associated protein 1 light chain 3; protein recruited from the cytosol (LC3-I) to the autophagosomal membrane where it is lipidated (LC3-II)) and p62/SQSTM1 (adaptor protein that serves as a link(More)
Parkinson's disease is the second common neurodegenerative disorder, after Alzheimer's disease. It is a clinical syndrome characterized by loss of dopamine-generating cells in the substancia nigra, a region of the midbrain. The etiology of Parkinson's disease has long been through to involve both genetic and environmental factors. Mutations in the(More)
PD (Parkinson's disease) is a neurodegenerative disorder caused by loss of dopamine-generating cells in the substantia nigra. The implication of genetic factors in the aetiology of PD has an essential importance in our understanding of the development of the disease. Mutations in the LRRK2 (leucine-rich repeat kinase 2) gene cause late-onset PD with a(More)
Talipexole is a non-ergot dopamine (DA) agonist that has been used in the treatment of Parkinson's disease. In the present study, we examined the effect of talipexole on paraquat (PQ)-induced N27 cell death and the intracellular pathways involved in this effect. Pretreatment of N27 cells with talipexole (1mM) resulted in significant protection against(More)
