| 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

| ACLY links energy metabolism provided by catabolic pathways to biosynthesis. ACLY, which has been found to be overexpressed in many cancers, converts citrate into acetyl-CoA and OAA.ATP citrate lyase exhibited upregulation in various tumours. General Tumour Biomarker •ACLY is a key enzyme in cancer metabolism. •ACLY is involved in glucose and lipid metabolism. •Many ACLY inhibitors were developed as anti-cancer agents. ACLY is a key enzyme in cellular metabolism that converts citrate into acetyl‐CoA and oxaloacetate. Acetyl‐CoA is a substrate for lipid synthesis and protein acetylation, processes that are often upregulated in cancer cells to support rapid growth and proliferation. ACLY is found overexpressed in many aggressive cancers. ACLY abundantly consumes citrate from nutrient catabolism (especially glucose and glutamine) to support protein acetylation and intense nucleotide and lipid synthesis. The significant decrease in cytosolic citrate appears to play a central role in cancer metabolism by enhancing the Warburg effect and activating the PI3K / AKT axis promoting ACLY activity in a feedback loop. Thus, the inhibition of factors regulating its expression (such as SREBP1) and its activation (such as AKT) could have an anti-proliferative effect. Elevated ACLY expression has been observed in a number of cancers. In many studies, high levels of ACLY have been associated with more aggressive disease and poorer prognoses.
