Abstract

Shatavarin IV (SIV), a steroidal saponin, is a major bioactive phytomolecule present in roots of Asparagus racemosus (Liliaceae) known for its anticancer activity. Age-associated neurodegenerative Parkinson's disease (PD) is characterised by alpha-synuclein aggregation in dopaminergic neuron resulting in neurodegeneration. The invention of bioactive molecules that delay aging and age-associated disorders endorses development of natural phytomolecule as a therapeutic agent for curing age-related diseases. Therefore, the present study for the first time explores the potential of SIV against aging and Parkinsonism utilising Caenorhabditis elegans model system. SIV significantly attenuated oxidative stress in terms of intracellular reactive oxygen species (ROS) as well as oxidative damage including protein carbonylation and also promotes longevity. SIV also significantly increased the mRNA expression of stress responsive genes namely sod-1, sod-2, sod-3, gst-4, gst-7 and ctl-2 suggesting its anti-oxidant property that might be contributed in the modulation of oxidative stress and promoting lifespan. Additionally, SIV improved PD symptoms by reducing the alpha-synuclein aggregation, lipid accumulation and enhancing dopamine level. A...Continue Reading

Alpha-Synuclein Aggregation (MDS)

Alpha-synucleins are small proteins that are believed to restrict the mobility of synpatic vesicles and inhibit neurotransmitter release. Aggregation of these proteins have been linked to several types of neurodegenerative diseases including dementia with Lewy bodies and Parkinson's disease. Here is the latest research on α-synuclein aggregation.

Cell Aging (Keystone)

This feed focuses on cellular aging with emphasis on the mitochondria, autophagy, and metabolic processes associated with aging and longevity. Here is the latest research on cell aging.
