| γ-Linolenic acid (GLA) — an omega-6 polyunsaturated fatty acid (18:3 n-6) found in high concentration in borage oil, evening primrose oil, and blackcurrant seed oil. Metabolized to dihomo-γ-linolenic acid (DGLA) → precursor of anti-inflammatory eicosanoids (e.g., PGE1). Primary mechanisms (conceptual rank): Bioavailability / PK relevance: Orally absorbed and incorporated into membrane phospholipids; rapidly elongated to DGLA. Plasma levels achievable with supplementation; cellular effects reflect incorporation over days–weeks (remodeling). In-vitro vs oral exposure: Direct tumor cytotoxicity generally observed at supra-physiologic concentrations; physiologic doses mainly alter lipid signaling rather than induce apoptosis. Clinical evidence status: Used for inflammatory conditions (e.g., dermatitis, RA); oncology data limited and inconsistent; no cancer approval. GLA (abundant in borage oil) has shown anti-proliferative and pro-apoptotic effects on multiple cancer cell lines and in animal models (mechanisms include ER stress, mitochondrial dysfunction, altered eicosanoid signaling).-Borage plants can contain unsaturated PAs(Pyrrolizidine alkaloids) which are hepatotoxic and genotoxic/carcinogenic. Many authorities advise only using borage oil products certified PA-free, and caution against long-term or high-dose use. -γ-gamma linolenic acid (GLA, 18:3n-6) are polyunsaturated fatty acids (PUFA) that improve the human health γ-Linolenic Acid (Borage Oil) — Cancer vs Normal Cell Pathway Map

| Cyclooxygenase-2 (COX-2) is an enzyme that plays a critical role in the conversion of arachidonic acid to prostaglandins, which are lipid compounds involved in various physiological processes, including inflammation, pain, and fever. COX-2 is an inducible enzyme, meaning its expression is typically low in normal tissues but can be upregulated in response to inflammatory stimuli, growth factors, and certain oncogenic signals. -Cyclooxygenase-2 (COX-2), the rate-limiting enzyme in prostaglandin biosynthesis, plays a key role in inflammation and circulatory homeostasis. -COX-2 is an inducible enzyme that is upregulated in response to pro-inflammatory signals, including cytokines (e.g., IL-1β, TNF-α) and growth factors. COX-2 is often overexpressed in various tumors, including colorectal, breast, lung, and prostate cancers. The prostaglandins produced by COX-2, particularly prostaglandin E2 (PGE2), have several effects that can facilitate cancer progression: Cell Proliferation: PGE2 can promote the proliferation of cancer cells by activating signaling pathways such as the PI3K/Akt and MAPK pathways. Nonselective NSAIDs, such as aspirin and ibuprofen, inhibit both COX-1 and COX-2. Epidemiological studies have suggested that regular use of NSAIDs may reduce the risk of certain cancers, particularly colorectal cancer. Drugs specifically targeting COX-2, such as celecoxib, have been developed. COX-2 and xanthine oxidase are ROS-producing pro-oxidant enzymes that contribute to inflammation. Elevated COX‑2 levels, often found in inflammatory conditions or certain types of cancers, can contribute to increased production of ROS. |
