Atg8/LC3

Autophagy-related 8;

Autophagy-related 8 proteins (Atg8s) are one of the 62 highly conserved eukaryote-specific protein families. Whereas yeast and other fungal species have a single Atg8 gene, multicellular animals, green plants and some protists have several. Animal Atg8 proteins comprise three subfamilies: microtubule-associated protein 1 light chain 3 (MAP1LC3, hereafter referred to as LC3), γ-aminobutyric acid receptor-associated protein (GABARAP) and Golgi-associated ATPase enhancer of 16 kDa (GATE-16).

Atg8 family members are expressed in various tissues, where they participate in multiple cellular processes, such as intracellular membrane trafficking and autophagy. Their role in autophagy has been intensively studied. Atg8 proteins undergo a unique ubiquitin-like conjugation to phosphatidylethanolamine on the autophagic membrane, a process essential for autophagosome formation.

    Citronellol
    		Inhibitor 98.60%
    Citronellol ((±)-Citronellol) is an orally active inducer of apoptosis. Citronellol can prevent oxidative stress, mitochondrial dysfunction, and apoptosis in the SH-SY5Y cell Parkinson's disease model induced by 6-OHDA by regulating the ROS-NO, MAPK/ERK, and PI3K/Akt signaling pathways. Citronellol can induce necroptosis in human lung cancer cells through the TNF-α pathway and accumulation of ROS. Citronellol can reduce the levels of LC-3 and p62 to regulate the autophagy pathway, inhibit oxidative stress and neuroinflammation, and thus have neuroprotective effects on Parkinson's rats. Citronellol exhibits anti-fungal activity against Trichophyton rubrum by inhibiting ergosterol synthesis.
