| Polyphenol of many herbs - rosemary, perilla, sage mint and basil. Rosmarinic acid (RA) is predominantly found in a variety of medicinal and culinary herbs, especially those belonging to the Lamiaceae family, including rosemary (Rosmarinus officinalis), basil (Ocimum basilicum), sage (Salvia officinalis), thyme (Thymus vulgaris), and mints (Mentha spp.). In addition to the Lamiaceae family, RA is also present in plants from other families, such as Boraginaceae and Apiaceae. -Rosmarinic acid is one of the hydroxycinnamic acids, and was initially isolated and purified from the extract of rosemary, a member of mint family (Lamiaceae) -Its chemical structure allows it to act as a free radical scavenger by donating hydrogen atoms to stabilize ROS and free radicals. RA’s dual nature as both a phenolic acid and a flavonoid-related compound enables it to chelate metal ions and prevent the formation of free radicals, thus interrupting oxidative chain reactions. It can modulate the activity of enzymes involved in OS, such as catalase (CAT), superoxide dismutase (SOD), and glutathione peroxidase (GPx), underscoring its potential role in preventing oxidative damage at the cellular level. -divided as rosemary extract, carnosic acid, rosmarinic acid? Summary: -Capacity to chelate transition metal ions, particularly ironChelator (Fe2+) and copper (Cu2+) -RA plus Cu(II)-induced oxidative DNA damage, which causes ROS -rosmarinic acid (RA) as a potential inhibitor of MARK4↓ (inhibiting to tumor growth, invasion, and metastasis) activity (IC50 = 6.204 µM) -Note half-life 1.5–2 hours. BioAv water-soluble, rapid absorbtion Pathways: - varying results of ROS up or down in cancer cells. Plus a report of lowering ROS and no effect on Tumor cell viability. However always seems to lower ROS↓ in normal cells. - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑, HSP↓, - No indication of Lowering AntiOxidant defense in Cancer Cells: - Raises AntiOxidant defense in Normal Cells:(and perhaps even in cancer cells) ROS↓, NRF2↑***, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : NLRP3↓, IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, MMPs↓, MMP2↓, MMP9↓, VEGF↓, ROCK1↓, RhoA↓, NF-κB↓, ERK↓, MARK4↓ - reactivate genes thereby inhibiting cancer cell growth(weak) : HDAC2↓, DNMTs↓weak, P53↑, HSP↓, - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, ERK↓, EMT↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓??, LDHA↓, PFKs↓, GRP78↑, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, EGFR↓, - inhibits Cancer Stem Cells (few references) : CSC↓, Hh↓, GLi1↓, - Others: PI3K↓, AKT↓, STAT↓, AMPK, ERK↓, JNK, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| Peroxisome proliferator-activated receptor gamma (PPAR-γ) is a type of nuclear receptor that plays a crucial role in regulating various biological processes, including glucose metabolism, lipid metabolism, and inflammation. It is primarily expressed in adipose tissue, but it is also found in other tissues, including the colon, breast, and prostate. PPAR-γ has been shown to have both tumor-suppressive and tumor-promoting effects, depending on the type of cancer and the context. In some cancers, activation of PPAR-γ can inhibit cell proliferation and induce apoptosis, while in others, it may promote tumor growth. PPARγ – Plays a central role in adipogenesis, lipid storage, and insulin sensitivity. – Widely expressed in adipose tissue, but also present in colon, breast, and immune cells. – In addition to metabolic functions, PPARγ regulates cell differentiation, apoptosis, and has anti-inflammatory effects. – Ligand binding (such as endogenous fatty acids or synthetic agonists like thiazolidinediones) alters transcriptional programs impacting cell cycle and survival. – In many cases, PPARγ is expressed in tumor cells, and its activation has been linked to induction of differentiation and growth arrest. – However, expression levels can differ based on tumor subtype, with some studies reporting elevated levels while others note reductions in aggressive tumors. – Crosstalk with other signaling pathways (e.g., Wnt/β-catenin, MAPK) can alter PPARγ's net effect in cancer cells. |
