Features:

Silymarin (Milk Thistle) Flowering herb related to daisy and ragweed family.
Silibinin (INN), also known as silybin is the major active constituent of silymarin, a standardized extract of the milk thistle seeds.
-a flavonoid combination of 65–80% of seven flavolignans; the most important of these include silybin, isosilybin, silychristin, isosilychristin, and silydianin. Silybin is the most abundant compound in around 50–70% in isoforms silybin A and silybin B

-Note half-life 6hrs?.
BioAv not soluble in water, low bioA (1%). 240mg yielded only 0.34ug/ml plasma level. oral administration of SM (equivalent to 120 mg silibinin), total (unconjugated + conjugated) silibinin concentration in plasma was 1.1–1.3 μg/mL, so can on acheive levels used in most in-vitro studies.
Pathways:
- results for both inducing and reducing ROS in cancer cells. In normal cell seems to consistently lower ROS. Given low bioavailability seems unlikely one could acheieve levels in vivo to raise ROS(except level in GUT could be much higher (800uM).

EMT, Epithelial-Mesenchymal Transition: Click to Expand ⟱

Source:

Type:

Biological process in which epithelial cells lose their cell polarity and cell-cell adhesion properties and gain mesenchymal traits, such as increased motility and invasiveness. This process is pivotal during embryogenesis and wound healing. Hh signaling pathway is able to regulate the EMT. Snail, E-cadherin and N-cadherin, key components of EMT; EMT-related factors, E-cadherin, N-cadherin, vimentin; The hallmark of EMT is the upregulation of N-cadherin followed by the downregulation of E-cadherin.
EMT is regulated by various signaling pathways, including TGF-β, Wnt, Notch, and Hedgehog pathways. Transcription factors such as Snail, Slug, Twist, and ZEB play critical roles in repressing epithelial markers (like E-cadherin) and promoting mesenchymal markers (like N-cadherin and vimentin).
EMT is associated with increased tumor aggressiveness, enhanced migratory and invasive capabilities, and resistance to apoptosis.
