“Fisetin selectively. induced apoptosis in senescent cells but not stem cells in vitro. Spermidine supplementation suppressed senescence in epithelial cells in mice when challenged with bleomycin, which causes oxidative stress.”

“Despite Nrf2's clear role in the body's response to sulforaphane, evidence indicates many other mechanisms may be involved, such as inducing apoptosis, halting cell cycle progression, inhibiting angiogenesis, and quenching oxidative stress and inflammation, thereby functioning in a synergistic fashion to potentiate sulforaphane's impact.”

“During prolonged fasting or starvation, the body survives by eliminating unnecessary cells via apoptosis, the process of programmed cell death. These cells will be replaced when food becomes available.”

“The three families of omega-3-derived SPMs, which include the resolvins, protectins, and maresins, promote apoptosis, regulate leukocyte activity, and reduce the production of proinflammatory molecules.”

“Studies in mice have shown that BDNF is important in maintaining the intestinal barrier, vital in containing pathogens or other undesirable material in the intestinal cavity. Mice that lacked one copy of the BDNF gene had fewer intestinal microvilli, increased mitochondrial swelling, and higher levels of epithelial cell apoptosis than normal mice.”

“FOXO3s participate in autophagy, but when autophagic mechanisms are disturbed, FOXO3s confer cellular sensitization to apoptosis, a type of programmed cell death. Following heat stress, FOXO3 proteins form a complex with sirtuin 1, or SIRT1, an enzyme that influences aging and longevity via multiple molecular pathways.”

“The mTOR network is a highly conserved signaling pathway that serves as a "hub," integrating input from the cellular environment about nutrient, oxygen, and energy levels, ultimately driving fundamental cellular responses such as growth, proliferation, apoptosis, and inflammation.”

“The mechanisms that drive cellular DNA release likely involve programmed cell death (apoptosis), unprogrammed, "accidental" cell death (necrosis), and the elimination of cells by the immune system.”

“Without oxygen, the heart’s cells undergo apoptosis and necrosis, or cell death. As cells die, they release proinflammatory signals that worsen cellular and tissue damage. This cardiac cascade can lead to long-term reductions in the heart’s pumping efficiency and, eventually, heart failure.”

“Four families of SPMs have been identified and include the resolvins, lipoxins, protectins, and maresins. These SPMs promote apoptosis, regulate leukocyte (white blood cell) activity, and reduce the production of proinflammatory mediators.”
