| Lignan found in bark of some magnolia species. Magnolol (MAG) — a bioactive biphenolic compound from Magnolia officinalis derived from the bark (roots and branches) of Magnolia species such as M. officinalis, M. obovata, and M. grandiflora The two main bioactive compounds isolated from these plants are MAG (5,5ʹ-diallyl-2,2ʹ-dihydroxybiphenyl) and Honokiol (3,5ʹ-diallyl-4,2ʹ-dihydroxybiphenyl) (Fig. 1) which are phenolic regioisomers. In the bark extracts of Magnolia plants, the composition of MAG ranges from 1 to 10%, while Honokiol comprises 1 to 5% Magnolol is a biphenolic neolignan isolated from the bark of Magnolia officinalis. It is structurally related to honokiol and is studied for anti-inflammatory, antioxidant, antimicrobial, and neuroactive effects. In preclinical oncology models, magnolol is reported to modulate NF-κB, STAT3, PI3K/AKT, MAPK, Wnt/β-catenin, and redox pathways, with downstream effects on cell-cycle arrest, apoptosis, invasion/EMT, and angiogenesis. Oral bioavailability is limited and many cytotoxic concentrations reported in vitro are in the tens of µM range, often above typical systemic levels from standard supplementation. major pathways and molecular targets involved in magnolol’s anticancer actions: -Apoptosis: ↑ Bax, ↓ Bcl-2, ↑ cytochrome c, ↑ caspase-9, ↑ caspase-3 -Arrests cell cycle at G0/G1 or G2/M phase:↓ Cyclin D1, CDK4, CDK6, Cyclin B1, CDK1 -Inhibits NF-κB activation: ↓ IκBα, COX-2, TNF-α -Inhibits PI3K, Akt, and mTOR phosphorylation -Suppresses angiogenesis: ↓ Bcl-XL, Mcl-1, VEGF, cyclin D1 -Inhibits β-catenin nuclear translocation -increase ROS production in tumor cells → triggers mitochondrial apoptosis -Magnolol activates Nrf2 in normal cells → upregulates HO-1, NQO1: Protects normal tissue from oxidative stress during chemotherapy or inflammation. Most in-vitro IC50 values fall in the 10–100 µM range, often above typical systemic exposure.

| Also known as scurfin FOXP3 (Forkhead box P3) is a transcription factor that serves as the master regulator of regulatory T cells (Tregs) Immune Suppression, Tregs, and Context-Dependent Tumor Biology Forkhead box P3 (FOXP3), an X-linked tumor suppressor gene. appears to function as a master regulator of the regulatory pathway in the development and function of regulatory T cells. FOXP3 can promote the apoptosis of breast cancer cells by upregulating the expression of PDCD4, thus exerting a tumor suppressive function. Increasing evidence has shown that FOXP3 is also expressed in tumor cells. However, the results of tumor FOXP3 is inconsistent and even the opposite. In some types of human cancers, the expression of FOXP3 is upregulated, and it can promote the development of cancers, leading to a poor prognosis. While in some other types of cancers, it is a different story. The reason for the contradictory data is unknown. Expression: FOXP3 is expressed in Tregs within the tumor microenvironment. Prognosis: High FOXP3 expression can correlate with poor prognosis, as it may indicate immune evasion by the tumor.(but not always) |
