Use of α-Carotene

α-Carotene, a precursor of vitamin A, is used as an anti-metastatic agent or as an adjuvant for anti-cancer drugs. α-Carotene is isolated from yellow-orange and dark-green vegetables[1][2].

In Vitro	α-Carotene (0.5-2.5 μM; 24 hours) significantly increases protein expression of TIMP-1 and TIMP-2 in a concentration-dependent manner in LLC cells. AC (0.5-2.5 μM) significantly increases PAI-1 protein expression. α-Carotene (2.5 μM) also significantly inhibits integrin β1-mediated phosphorylation of focal adhesion kinase (FAK) which then decreased the phosphorylation of MAPK family[2]. α-Carotene (0.5, 1, 2.5 μM; 48 hours) significantly and concentration-dependently inhibits invasion of LLC during 48 h of incubation[2]. α-Carotene (0.5, 1, 2.5 μM; 24 hours) significantly decreases activities of MMP-9, -2 and uPA in concentration-dependent manner in LLC cells[2]. α-Carotene (2, 5, 10 μM; 7 days) inhibits the proliferation of the human neuroblastoma cell line GOTO in a dose- and time-dependent manner. α-Carotene (5 μM; 48 hours) halts the cell cycle at the G0/G1 phase concomitantly with a reduction in the mRNA expression of the protooncogene N-Myc[3]. Western Blot Analysis[2] Cell Line: Lewis lung carcinoma (LLC) cells Concentration: 0.5, 1, 2.5 μM Incubation Time: 24 hours Result: Significantly increased protein expression of TIMP-1 and TIMP-2 in a concentration-dependent manner in LLC cells.
In Vivo	α-Carotene (5 mg/kg; oral; twice a week; for additional 3 weeks) alone significantly decreases lung metastasis without affecting primary tumor growth[2]. Animal Model: C57BL/6 male mice (4 weeks old; 20-25 g) with LLC cells[2] Dosage: 5 mg/kg Administration: Oral; twice a week; for additional 3 weeks Result: Significantly decreased lung metastasis.
