Boron is a trace mineral. Used in treating yeast infections, improving athletic performance, or preventing osteoporosis. Current research suggests that boric acid can modulate intercellular calcium levels—with potential implications for cancer therapy—by: -Altering calcium channel activity and calcium influx, -Modifying downstream calcium-dependent signaling, and -Inducing apoptotic pathways preferentially in cancer cells due to their altered calcium handling dynamics. Abnormal increases in [Ca²⁺]ᵢ can trigger mitochondrial dysfunction and activate calcium-dependent apoptotic pathways. Boric acid has been observed in some cell culture studies to induce apoptosis in cancer cells. In normal cells, modest changes in [Ca²⁺]ᵢ induced by boric acid may not reach a threshold that triggers apoptosis or other stress responses. This could lead to a relative sparing of normal cells compared to cancer cells. Pathways: 1.Calcium Signaling Pathway In many cases, boron appears to normalize dysregulated calcium levels in cancer cells, often leading to an increase in calcium levels that can trigger calcium-dependent apoptotic pathways. 2.Apoptotic Pathways (Intrinsic and Extrinsic). Direction of Modulation: • Boron compounds may enhance the activation of apoptotic cascades. • Typically, an increase in intracellular calcium (as noted above) can further lead to mitochondrial dysfunction, cytochrome c release, and subsequent caspase activation, thereby promoting apoptosis. 3.PI3K/AKT/mTOR Pathway • Some studies indicate that boron-containing compounds can inhibit this pathway. • Inhibition of PI3K/AKT/mTOR signaling reduces survival signals and can decrease cellular proliferation and growth in tumor cell. 4.MAPK/ERK Pathway Boron may modulate the MAPK/ERK cascade by either dampening overactive mitogenic signals or altering the stress response. • This modulation can lead to reduced proliferation signals and may promote cell cycle arrest in cancer cells. 5.NF-κB Signaling Pathway • Some reports indicate that boron compounds can suppress NF-κB activity. • This suppression might be achieved indirectly through modulation of upstream signals (such as changes in calcium or the cellular redox status) leading to decreased transcription of pro-survival and pro-inflammatory genes. 6.Wnt/β-Catenin Pathway • Inhibition of Wnt/β-catenin signaling may interfere with proliferation and the maintenance of cancer stem cell populations. ROS: -ROS induction may be dose related. -Some studies report that when boron compounds are combined with other treatments (like chemotherapy or radiotherapy), there is a synergistic increase in ROS generation. Boron’s effects in a cancer context generally lean toward: • Normalizing dysregulated calcium signaling to push cells toward apoptotic death • Inhibiting pro-survival pathways such as PI3K/AKT/mTOR and NF-κB (1) is essential for the growth and maintenance of bone; (2) greatly improves wound healing; (3) beneficially impacts the body's use of estrogen, testosterone, and vitamin D; (4) boosts magnesium absorption; (5) reduces levels of inflammatory biomarkers, such as high-sensitivity C-reactive protein (hs-CRP) and tumor necrosis factor α (TNF-α); (6) raises levels of antioxidant enzymes, such as superoxide dismutase (SOD), catalase, and glutathione peroxidase; (7) protects against pesticide-induced oxidative stress and heavy-metal toxicity; (8) improves the brains electrical activity, cognitive performance, and short-term memory for elders; (9) influences the formation and activity of key biomolecules, such as S-adenosyl methionine (SAM-e) and nicotinamide adenine dinucleotide (NAD(+)); (10) has demonstrated preventive and therapeutic effects in a number of cancers, such as prostate, cervical, and lung cancers, and multiple and non-Hodgkin's lymphoma; and (11) may help ameliorate the adverse effects of traditional chemotherapeutic agents. -Note half-life 21 hrs average BioAv very high, 85-100% Pathways: - induce ROS productionin cancer cells, while reducing ROS in normal cells. - ROS↑ related: MMP↓(ΔΨm), ER Stress↑, UPR↑, GRP78↑, Ca+2↑,(contrary) Cyt‑c↑, Caspases↑, DNA damage↑, cl-PARP↑,(contrary) HSP↓, - Debateable if Lowers AntiOxidant defense in Cancer Cells: NRF2↓(most contrary), SOD↓(some contrary), GSH↓, Catalase↓(some contrary), HO1↓(contrary), GPx↓(some contrary) - Raises AntiOxidant defense in Normal Cells: ROS↓, NRF2↑, SOD↑, GSH↑, Catalase↑, - lowers Inflammation : NF-kB↓, COX2↓, Pro-Inflammatory Cytokines : NLRP3↓, IL-1β↓, TNF-α↓, IL-6↓, - inhibit Growth/Metastases : TumMeta↓, TumCG↓, EMT↓, IGF-1↓, VEGF↓, RhoA↓, NF-κB↓, TGF-β↓, α-SMA↓, ERK↓ - reactivate genes thereby inhibiting cancer cell growth : HDAC↓, P53↑, HSP↓, - some indication of Cell cycle arrest : TumCCA↑, cyclin D1↓, cyclin E↓, CDK2↓, CDK4↓, CDK6↓, - inhibits Migration/Invasion : TumCMig↓, TumCI↓, TNF-α↓, ERK↓, EMT↓, - small indication of inhibiting glycolysis : HIF-1α↓, cMyc↓, GRP78↑, Glucose↓, - small indication of inhibiting angiogenesis↓ : VEGF↓, HIF-1α↓, EGFR↓, - Others: PI3K↓, AKT↓, JAK↓, STAT↓, Wnt↓, β-catenin↓, AMPK, ERK↓, - SREBP (related to cholesterol). - Synergies: chemo-sensitization, chemoProtective, RadioSensitizer, RadioProtective, Others(review target notes), Neuroprotective, Cognitive, Renoprotection, Hepatoprotective, CardioProtective, - Selectivity: Cancer Cells vs Normal Cells |
