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.
CDK4, Cyclin-dependent kinase 4: Click to Expand ⟱
Source:
Type:
Cyclin-dependent kinase 4 (CDK4) is a key regulator of the cell cycle, particularly in the transition from the G1 phase to the S phase. Its expression and activity are often altered in various cancers, contributing to tumorigenesis.
CDK4 is frequently overexpressed in various cancers, and its expression levels can serve as a prognostic marker.
