Identification of 2,4-dihydroxy-azaflavanone as an allosteric activator of SIRT1 and its potential role in cellular models of Parkinson's disease.

NAD+ signaling in Parkinson's disease: molecular mechanisms and therapeutic perspectives

Parkinson's disease (PD) is the second most prevalent neurodegenerative disorder worldwide, characterized by the progressive loss of dopaminergic neurons in the substantia nigra, accumulation of α-synuclein (α-syn), mitochondrial dysfunction, and neuroinflammation. Nicotinamide adenine dinucleotide (NAD+), a crucial co...

Dihydroquercetin Activates AMPK/SIRT1/PGC-1α Signaling to Attenuate Arsenic Trioxide-Induced Apoptosis and Ferroptosis in AC16 Cells and HUVECs

Findings position DHQ as a promising candidate for protecting cardiomyocytes and endothelial cells from ATO-induced injury by activating the AMPK/SIRT1/PGC-1α pathway, thereby reducing oxidative stress and concurrently inhibiting apoptosis and ferroptosis.

SIRT1/PGC-1α-regulated mitochondrial biogenesis is involved in T-2 toxin-induced chondrocyte injury.

T-2 toxin, a type A trichothecene mycotoxin, has been implicated as an environmental risk factor for Kashin-Beck disease (KBD), an endemic osteoarthropathy characterized by cartilage damage. However, whether T-2 toxin impairs mitochondrial biogenesis in chondrocytes and the underlying regulatory mechanism remain unclea...

The therapeutic potential of melatonin: Focus on the SIRT1 signaling pathway

Hinokitiol as a Potential GPX4 Allosteric Modulator to Prevent Ferroptosis-mediated Neurodegeneration in Parkinson’s Disease

Fungal-Derived Decahydrofluorene Alkaloids Promote Mitochondrial Resilience and Neuroprotection in Cellular and Animal Models of Parkinson’s Disease

Parkinson’s disease (PD) is characterized by oxidative stress, mitochondrial dysfunction, and dopaminergic neuron loss, for which effective treatments remain unavailable. Here, we report CL0179, a fungal-derived decahydrofluorene alkaloid with antioxidant-associated neuroprotective properties, and evaluate its effects...
