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

cycE, Cyclin E: Click to Expand ⟱
Source:
Type:
Cyclin E regulates multiple downstream molecules, such as the retinoblastoma susceptibility gene (RB1) and the transcription factor E2F.
Cyclin E is a prognostic marker in breast cancer, its altered expression increased with the increasing stage and grade of the tumor.
Cyclin E is a regulatory protein that plays a critical role in the cell cycle, particularly in the transition from the G1 phase to the S phase. Its expression levels can significantly influence cancer progression and patient prognosis.

Cyclin E expression is frequently elevated in various cancers and is generally associated with poor prognosis. Its role in promoting cell cycle progression makes it a potential biomarker for tumor aggressiveness and patient outcomes.

- in-vitro, CRC, HCT116 - in-vitro, CRC, SW48
TumCG↓, SKN inhibited colon cancer cell growth, suppressed both constitutive and IL-6-induced STAT3 phosphorylation, and downregulated the expression of ADAM17
p‑STAT3↓,
ADAM17↓,
Apoptosis↑, SKN promoted cell apoptosis, as evidenced by increased expression levels of cleaved caspase-3 and cleaved PARP in both cell lines
Casp3↑,
cl‑PARP↑,
cycD1↓, SKN decreased the expression of cyclin D1 and cyclin E1, thus suggesting the disruption of the cell cycle and the suppression of cell growth
cycE↓,
TumCCA↑,
JAK1?, The inhibitory effects of SKN on the phosphorylation of both JAK1 and JAK2 in the two cell lines were also observed
p‑JAK1↓,
p‑JAK2↓,
p‑eIF2α↑, phosphorylation levels of eIF2α were enhanced by SKN (20 µM) in the HCT116 and SW480 colon cancer cells
eff↓, NAC decreased SKN-induced p-eIF2α expression and reversed the SKN-mediated downregulation of ADAM17 protein expression
ROS↑, suppressed the expression of ADAM17 mediated by ROS-associated p-eIF2α expression in the HCT116 and SW480 colon cancer cells
IL6↓, demonstrated that the antitumor effects of SKN on colon cancer cells were associated with its inhibition of the IL-6/STAT3 signaling pathway.

- in-vitro, Lung, H1299 - in-vitro, Lung, H460
TumCP↓, Results showed that shikonin inhibited the NSCLC H1299 cell proliferation in a dose-dependent manner.
survivin↓, Shikonin also inhibited the mRNA expression and protein level of survivin in H1299 cells
TumCCA↓, Shikonin arrested H1299 cell cycle at the G0/G1 phase by regulating CDK/cyclin family members
CDK2↓,
CDK4↓,
XIAP↓, shikonin regulated the expression of X-linked inhibitor of apoptosis- (XIAP-) mediated caspases 3 and 9, thus leading to the damage of mitochondrial membrane potential and induction of H1299 cell apoptosis.
Casp3↑, subsequently regulates the protein expression of XIAP/caspase 3/9, CDK2/4, and cyclin E/D1.
