Thymoquinone is a bioactive compound found in the seeds of Nigella sativa, commonly known as black seed or black cumin. Pathways: -Cell cycle arrest, apoptosis induction, ROS generation in cancer cells -inhibit the activation of NF-κB, Suppress the PI3K/Akt signaling cascade -Inhibit angiogenic factors such as VEGF, MMPs -Inhibit HDACs, UHRF1, and DNMTs -Note half-life 3-6hrs. BioAv low oral bioavailability due to its lipophilic nature. Note refridgeration of Black seed oil improves the stability of TQ. DIY: ~1 part lecithin : 2–3 parts black seed oil : 4–5 parts warm water.

(Also known as Hsp32 and HMOX1) HO-1 is the common abbreviation for the protein (heme oxygenase‑1) produced by the HMOX1 gene. HO-1 is an enzyme that plays a crucial role in various cellular processes, including the breakdown of heme, a toxic molecule. Research has shown that HO-1 is involved in the development and progression of cancer. -widely regarded as having antioxidant and cytoprotective effects -The overall activity of HO‑1 helps to reduce the pro‐oxidant load (by degrading free heme, a pro‑oxidant) and to generate molecules (like bilirubin) that can protect cells from oxidative damage Studies have found that HO-1 is overexpressed in various types of cancer, including lung, breast, colon, and prostate cancer. The overexpression of HO-1 in cancer cells can contribute to their survival and proliferation by: Reducing oxidative stress and inflammation Promoting angiogenesis (the formation of new blood vessels) Inhibiting apoptosis (programmed cell death) Enhancing cell migration and invasion When HO-1 is at a normal level, it mainly exerts an antioxidant effect, and when it is excessively elevated, it causes an accumulation of iron ions. A proper cellular level of HMOX1 plays an antioxidative function to protect cells from ROS toxicity. However, its overexpression has pro-oxidant effects to induce ferroptosis of cells, which is dependent on intracellular iron accumulation and increased ROS content upon excessive activation of HMOX1. -Curcumin Activates the Nrf2 pathway leading to HO‑1 induction; known for its anti‑inflammatory and antioxidant effects. -Resveratrol Induces HO‑1 via activation of SIRT1/Nrf2 signaling; exhibits antioxidant and cardioprotective properties. -Quercetin Activates Nrf2 and related antioxidant pathways; contributes to anti‑oxidative and anti‑inflammatory responses. -EGCG Promotes HO‑1 expression through activation of the Nrf2/ARE pathway; also exhibits anti‑inflammatory and anticancer properties. -Sulforaphane One of the most potent natural HO‑1 inducers; triggers Nrf2 nuclear translocation and upregulates a battery of phase II detoxifying enzymes. -Luteolin Induces HO‑1 via Nrf2 activation; may also exert anti‑inflammatory and neuroprotective effects in various cell models. -Apigenin Has been reported to induce HO‑1 expression partly via the MAPK and Nrf2 pathways; also known for anti‑inflammatory and anticancer activities. |
