| Berberine — Berberine is a protoberberine/isoquinoline alkaloid natural product found in plants such as Coptis, Berberis, and Phellodendron. It is a small-molecule phytochemical with pleiotropic metabolic, anti-inflammatory, and anticancer signaling effects rather than a single highly selective target profile. Its standard abbreviation is BBR. In oncology it is best classified as a multitarget natural-product lead compound and adjunct-sensitizer candidate, with strong preclinical evidence but no established standard anticancer regulatory use. Its translational profile is shaped by very low conventional oral bioavailability, extensive first-pass metabolism, broad tissue distribution, and substantial context dependence between cancer-cell pro-death effects and normal-cell cytoprotective redox effects. Primary mechanisms (ranked):
Bioavailability / PK relevance: Conventional oral berberine has poor systemic bioavailability, often cited as below 1% in animal studies, because of limited absorption, P-glycoprotein efflux, first-pass intestinal/hepatic metabolism, and self-aggregation. Human exposure is usually in the low ng/mL plasma range with conventional dosing, while multiple metabolites may contribute to activity. Tissue distribution can exceed plasma levels, but PK remains a major clinical translation constraint. In-vitro vs systemic exposure relevance: Many anticancer in-vitro studies use roughly 10–100 µM, commonly around 20–50 µM, which usually exceeds readily achievable conventional plasma exposure after standard oral dosing. Therefore, direct translation of cell-culture potency to systemic monotherapy expectations is limited unless local gut exposure, tissue accumulation, metabolite contribution, formulation enhancement, or combination use is specifically relevant. Clinical evidence status: Strong preclinical and mechanistic evidence; limited early human oncology/chemoprevention evidence; no established phase III anticancer efficacy standard and no mainstream regulatory approval as an anticancer drug. Current clinical relevance is best viewed as investigational and adjunct-oriented rather than proven standalone oncology therapy. Berberine is a chemical found in some plants like European barberry, goldenseal, goldthread, Oregon grape, phellodendron, and tree turmeric. Berberine is a bitter-tasting and yellow-colored chemical.Coptis (commonly referring to Coptidis Rhizoma, a traditional Chinese medicinal herb) contains bioactive alkaloids (most notably berberine and coptisine) that have been studied for their pharmacological effects—including their influence on reactive oxygen species (ROS) and related pathways. – Berberine is known for its relatively low oral bioavailability, often cited at less than 1%. This low bioavailability is mainly due to poor intestinal absorption and active efflux by transport proteins such as P-glycoprotein. – Despite the low bioavailability, berberine is still pharmacologically active, and its metabolites may also contribute to its overall effects. • Effective Dosage in Studies – Many clinical trials or preclinical studies use dosages in the range of 500 to 1500 mg per day, typically administered in divided doses. – Therefore, to obtain a bioactive dose of berberine, supplementation in a standardized extract form is necessary. -IC50 in cancer cell lines: Approximately 10–100 µM (commonly around 20–50 µM in many models) -IC50 in normal cell lines: Generally higher (often above 100 µM), although this can vary with cell type - In vivo studies: Dosing regimens in animal models generally range from about 50 to 200 mg/kg - very effective AChE inhibitor (Alzheimers) - Berberine may enhance the effects of blood-thinning medications like warfarin and aspirin. -Note half-life reports vary 2.5-90hrs?. -low solubility of apigenin in water : BioAv Pathways: - induce ROS production - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, Ca+2↑, Cyt‑c↑, Caspases↑, DNA damage↑, UPR↑, cl-PARP↑, HSP↓ - Lowers AntiOxidant defense in Cancer Cells: NRF2↓, GSH↓ - Raises AntiOxidant defense in Normal Cells: NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, p38↓, Pro-Inflammatory Cytokines : IL-1β↓, TNF-α↓, IL-6↓, IL-8↓ - PI3K/AKT(Inhibition), JAK/STATs, Wnt/β-catenin, AMPK, MAPK/ERK, and JNK. - inhibit Growth/Metastases : , MMPs↓, MMP2↓, MMP9↓, IGF-1↓, uPA↓, VEGF↓, ROCK1↓, FAK↓, RhoA↓, NF-κB↓, CXCR4↓, TGF-β↓, α-SMA↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, DNMT1↓, EZH2↓, P53↑, HSP↓ - cause Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, FAK↓, ERK↓, - inhibits glycolysis /Warburg Effect and ATP depletion : HIF-1α↓, PKM2↓, cMyc↓, GLUT1↓, LDH↓, LDHA↓, HK2↓, PFKs↓, PDKs↓, Glucose↓, GlucoseCon↓ - inhibits angiogenesis↓ : VEGF↓, HIF-1α↓, Notch↓, FGF↓, PDGF↓, EGFR↓, Integrins↓, - inhibits Cancer Stem Cells : CSC↓, Hh↓, GLi1↓, CD133↓, β-catenin↓, n-myc↓, sox2↓, notch2↓, nestin↓, OCT4↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK↓, α↓, ERK↓, JNK, - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells

| Also known as CP32. Cysteinyl aspartate specific proteinase-3 (Caspase-3) is a common key protein in the apoptosis and pyroptosis pathways, and when activated, the expression level of tumor suppressor gene Gasdermin E (GSDME) determines the mechanism of tumor cell death. As a key protein of apoptosis, caspase-3 can also cleave GSDME and induce pyroptosis. Loss of caspase activity is an important cause of tumor progression. Many anticancer strategies rely on the promotion of apoptosis in cancer cells as a means to shrink tumors. Crucial for apoptotic function are executioner caspases, most notably caspase-3, that proteolyze a variety of proteins, inducing cell death. Paradoxically, overexpression of procaspase-3 (PC-3), the low-activity zymogen precursor to caspase-3, has been reported in a variety of cancer types. Until recently, this counterintuitive overexpression of a pro-apoptotic protein in cancer has been puzzling. Recent studies suggest subapoptotic caspase-3 activity may promote oncogenic transformation, a possible explanation for the enigmatic overexpression of PC-3. Herein, the overexpression of PC-3 in cancer and its mechanistic basis is reviewed; collectively, the data suggest the potential for exploitation of PC-3 overexpression with PC-3 activators as a targeted anticancer strategy. Caspase 3 is the main effector caspase and has a key role in apoptosis. In many types of cancer, including breast, lung, and colon cancer, caspase-3 expression is reduced or absent. On the other hand, some studies have shown that high levels of caspase-3 expression can be associated with a better prognosis in certain types of cancer, such as breast cancer. This suggests that caspase-3 may play a role in the elimination of cancer cells, and that therapies aimed at activating caspase-3 may be effective in treating certain types of cancer. Procaspase-3 is a apoptotic marker protein. Prognostic significance: • High Cas3 expression: Associated with good prognosis and increased sensitivity to chemotherapy in breast, gastric, lung, and pancreatic cancers. • Low Cas3 expression: Linked to poor prognosis and increased risk of recurrence in colorectal, hepatocellular carcinoma, ovarian, and prostate cancers. |
