| Features: |
| Hydrogen sulfide (H₂S), a gaseous signaling molecule, has been implicated in Alzheimer’s disease (AD) pathology with both neuroprotective and neurotoxic roles, depending on concentration, source, and context. - It was found that the endogenous H2S level in the brain of AD patients was significantly lower than that of normal people. -A cysteine-rich diet or supplementation with an appropriate amount of N-acetylcysteine is beneficial to the synthesis of H2S in the brain -Activates Nrf2, upregulates antioxidant genes Reduces oxidative stress, neuroprotective. -Inhibits NF-κB activation Suppresses inflammatory cytokines like TNF-α, IL-1β -Reduces Aβ aggregation and toxicity -Enhances cerebral blood flow |

| APP typically refers to the amyloid precursor protein, best known for its role in Alzheimer’s disease. -APP is mainly distributed in the synapses of neurons in the brain and Aβ peptide was produced from APP proteolysis by β-secretase and γ-secretase complex. -decreased APP in 5×FAD mice ameliorated their amyloid plaques and behavior activity. • APP is found to be upregulated in some cancers such as certain breast cancers, colon cancers, and lung cancers. Elevated levels may influence processes such as cell proliferation, adhesion, migration, and even invasion. |
