| Spermidine : Polyamine (natural small molecule) Sources: Found in foods like wheat germ, soybeans, mushrooms, aged cheese, and fermented foods. Typical dietary intake is ~5–20 mg/day.Top food sources = wheat germ > soybeans > aged cheddar > mushrooms > rice bran/legumes. Ripening / fermentation: especially in aged or fermented foods like cheese, where spermidine and other polyamines can rise during ripening because microbial activity and protein breakdown contribute to amine formation. That is one reason aged cheeses can rank unusually high. Cooking: boiling and grilling significantly reduced polyamine content in many foods, whereas microwave and sous-vide tended to preserve more. Primary Actions: Autophagy induction, mild ROS modulation, epigenetic regulation, and modulation of polyamine metabolism. Pathway Effect of Spermidine Autophagy (ATG genes) ↑ Induction, Beclin-1 activation mTORC1 signaling ↓ Inhibition, promotes catabolic metabolism p53/p21 Modulation via epigenetic changes Polyamine metabolism Supports or stresses proliferating cells ROS / redox balance Mild modulation; sensitizes cancer cells to ROS stressContext-dependent risk: High spermidine levels might support tumor growth in polyamine-addicted cancers; dose, timing, and tumor type matter. Chemo interaction: Generally compatible; not expected to block ROS-dependent therapy at oral doses. Spermidine, a biogenic polyamine that declines along with aging, shows promise in restoring antitumor immunity by enhancing mitochondrial fatty acid oxidation (FAO) Spermidine — Cancer vs Normal Cell Effects

| H2O2 is a reactive oxygen species (ROS) that can induce oxidative stress in cells. While low levels of ROS can promote cell signaling and proliferation, high levels can lead to DNA damage, apoptosis (programmed cell death), and other cellular dysfunctions. This dual role means that H2O2 can contribute to cancer development and progression, as oxidative stress can lead to mutations and genomic instability. H2O2 can enhance the effectiveness of certain chemotherapeutic agents by increasing oxidative stress in cancer cells. Additionally, localized delivery of H2O2 has been explored as a means to selectively target and kill cancer cells while sparing normal cells. Cancer cells often exhibit altered metabolism, leading to increased production of reactive oxygen species, including H2O2. This can result from enhanced mitochondrial activity, increased glycolysis, or other metabolic adaptations that are characteristic of cancer. Reported H2O2 concentrations for representative compounds.
Note: many products at lower concentrations act as antioxidants, instead of Prooxidants. Generally, increased hydrogen peroxide and oxidative stress are associated with poor outcomes, while the specific context and cellular environment can modulate its effects. |
