Api, Apigenin (mainly Parsley): Click to Expand ⟱
Features:
Apigenin present in parsley, celery, chamomile, oranges and beverages such as tea, beer and wine.
"It exhibits cell growth arrest and apoptosis in different types of tumors such as breast, lung, liver, skin, blood, colon, prostate, pancreatic, cervical, oral, and stomach, by modulating several signaling pathways."
-Note half-life reports vary 2.5-90hrs?.
-low solubility of apigenin in water : BioAv (improves when mixed with oil/dietary fat or lipid based formulations)
-best oil might be MCT oils (medium-chain fatty acids)

- Selectivity: Cancer Cells vs Normal Cells

Apigenin exhibits biological effects (anticancer, anti-inflammatory, antioxidant, neuroprotective, etc.) typically at concentrations roughly in the range of 1–50 µM.

Parsley microgreens can contain up to 2-3 times more apigenin than mature parsley.
Apigenin is typically measured in the range of 1-10 μM for biological activity. Assuming a molecular weight of 270 g/mol for apigenin, we can estimate the following μM concentrations:
10uM*5L(blood)*270g/mol=13.5mg apigenin (assumes 100% bioavailability)
then an estimated 10-20 mg of apigenin per 100 g of fresh weight parlsey
2.2mg/g of apigenin fresh parsley
45mg/g of apigenin in dried parsley (wikipedia)
so 100g of parsley might acheive 10uM blood serum level (100% bioavailability)
BUT bioavailability is only 1-5%
(Supplements available in 75mg liposomal)( Apigenin Pro Liposomal, 200 mg from mcsformulas.com)

A study had 2g/kg bw (meaning 160g for 80kg person) delivered a maximum 0.13uM of plasma concentration @ 7.2hrs.
Assuming parsley is 90-95% water, then that would be ~16g of dried parsley
Conclusion: to reach 10uM would seem very difficult by oral ingestion of parsley.
Other quotes:
      “4g of dried parsley will be enough for 50kg adult”
      5mg/kg BW yields 16uM, so 80Kg person means 400mg (if dried parsley is 130mg/g, then would need 3g/d)
In many cancer cell lines, concentrations in the range of approximately 20–40 µM have been reported to shift apigenin’s activity from mild antioxidant effects (or negligible ROS changes) toward a clear pro-oxidant effect with measurable ROS increases.

Low doses: At lower concentrations, apigenin is more likely to exhibit its antioxidant properties, scavenging ROS and protecting cells from oxidative stress.
In normal cells with robust antioxidant systems, apigenin’s antioxidant effects might prevail, whereas cancer cells—often characterized by an already high level of basal ROS—can be pushed over the oxidative threshold by increased ROS production induced by apigenin.
In environments with lower free copper levels, this pro-oxidant activity is less pronounced, and apigenin may tilt the balance toward its antioxidant function.
HDAC, Histone deacetylases: Click to Expand ⟱
Source:
Type:
Enzymes involved in regulating gene expression by removing acetyl groups from histones, the proteins around which DNA is wrapped.
-Many cancers exhibit altered expression levels of HDACs, which can contribute to the dysregulation of genes involved in cell growth, survival, and differentiation.
-HDACs can repress the expression of tumor suppressor genes, leading to uncontrolled cell proliferation and survival. This repression can be a key factor in the development and progression of cancer.
-HDAC inhibitors (HDACi) have been developed and are being investigated for their ability to reactivate silenced genes, induce cell cycle arrest, and promote apoptosis in cancer cells.
-HDAC1, HDAC2): Often overexpressed in various cancers, including breast, prostate, and colorectal cancers. Their overexpression is associated with poor prognosis.
-HDAC4, HDAC5): These may have both oncogenic and tumor-suppressive roles depending on the context and cancer type.
-While HDACs are not classified as traditional oncogenes, their overexpression and activity can contribute to oncogenic processes.
-HDAC inhibitor works by preventing the removal of acetyl groups from histones, thereby modulating gene expression, influencing cell behavior, and potentially reversing aberrant gene silencing seen in various diseases.
-HDAC inhibitors can help reactivate these genes, thereby inhibiting growth and inducing apoptosis in cancer cells.
