SK, Shikonin: Click to Expand ⟱
Features:
The (R)-enantiomer of alkannin is known as shikonin, and the racemic mixture of the two is known as shikalkin.
Shikonin is a naphthoquinone derivative primarily isolated from the roots of plants in the Boraginaceae family (e.g., Lithospermum erythrorhizon).
Shikonin is the main active component of a Chinese medicinal plant 'Zi Cao'
-Shikonin is a major component of zicao (purple gromwell, the dried root of Lithospermum erythrorhizon), a Chinese herbal medicine with anti-inflammatory properties
-Quinone methides (QMs) are highly reactive intermediates formed from natural compounds like shikonin
-ic50 cancer cells 1-10uM, normal cells >10uM

-known as Glycolysis inhibitor: ( inhibit pyruvate kinase M2 (PKM2*******), a key enzyme in the glycolytic pathway)

Available from mcsformulas.com Shikonin Pro Liposomal, 30 mg

β-catenin/ZEB1, β-catenin/ZEB1: Click to Expand ⟱
Source: HalifaxProj (inactivate)
Type:
β-catenin and ZEB1 are two important proteins that play significant roles in cancer biology, particularly in the processes of cell adhesion, epithelial-mesenchymal transition (EMT), and tumor progression.
β-catenin is a key component of the Wnt signaling pathway, which is crucial for cell proliferation, differentiation, and survival. It also plays a role in cell-cell adhesion by linking cadherins to the actin cytoskeleton.
Role in Cancer: ZEB1 is often upregulated in cancer and is associated with increased invasiveness and metastasis. It can repress epithelial markers (like E-cadherin) and promote mesenchymal markers (like N-cadherin and vimentin), facilitating the transition to a more aggressive cancer phenotype.

(MMP)-2 and MMP-9, which are the down-stream targets of β-catenin and play a crucial role in cancer cell metastasis.

tumCV↓, results revealed that shikonin potently decreased the viabilities of TNBC MDA-MB-231 and 4T1 cells but showed less cytotoxicity to normal mammary epithelial MCF-12A cells
selectivity↑,
EMT↓, shikonin reversed the epithelial-to-mesenchymal transition (EMT) in MDA-MB-231 and 4T1 cells.
TumCMig↓, Shikonin depressed cell migration and invasion, upregulated E-cadherin levels, downregulated N-cadherin, vimentin, and Snail levels, and reorganized the cytoskeletal proteins F-actin and vimentin.

β-catenin/ZEB1↓, Shikonin reversed EMT by inhibiting activation of β-catenin signaling through attenuating β-catenin expression
GSK‐3β↑, shikonin upregulated glycogen synthase kinase 3β (GSK-3β) levels, leading to enhanced phosphorylation and decreased levels of β-catenin.
