Berberine's cancer-inhibiting properties.

Berberine is a natural compound found in various plant, including goldenseal, barberry, and Oregon grape. 

It has been shown to have anti-cancer properties by modulating several cancer-related signaling pathways. These include the PI3K/AKT/mTOR, MAPK/ERK, Wnt/β-catenin {ref|ref}, and NF-κB pathways. 

• inhibition of NF-kB
• HDAC modulation
• Cox-2 inhibition
• Suppresses HIF-1α
• PD-L1 ⏷
• Suppression of 5α-Reductase: 5α-Reductase is an enzyme that converts testosterone into the more potent androgen dihydrotestosterone (DHT).
• 1 gr a day lowered fasting blood sugar by 20%
• OXPHOS inhibitor
• Berberine Suppresses Glutamine Uptake by Inhibiting SLC1A5

With the cotreatment with LPS, which could boost the expression of cytokines in these cancer cells, berberine significantly reduced the increased expression of TNF-α and IL-6. Meanwhile, we found that berberine inhibited the activation of NF-κB by preventing the degradation of IκBα."
