生物活性

产品描述	维生素 A 的前体，用作抗转移剂或用作抗癌药的佐剂。α-Carotene 是从橙黄色和深绿色蔬菜中分离出来的。
体外研究	α-Carotene (0.5-2.5μM; 24 hours) significantly increases protein expression of TIMP-1 and TIMP-2 in a concentrationdependent manner in LLC cells. AC (0.5-2.5μM) significantly increases PAI-1 protein expression. α-Carotene (2.5μM) also significantly inhibits integrin β1-mediated phosphorylation of focal adhesion kinase (FAK) which then decreased the phosphorylation of MAPK family. α-Carotene (0.5, 1, 2.5μM; 48 hours) significantly and concentration-dependently inhibits invasion of LLC during 48 h of incubation. α-Carotene (0.5, 1, 2.5μM; 24 hours) significantly decreases activities of MMP-9, -2 and uPA in concentration-dependent manner in LLC cells. α-Carotene (2, 5, 10μM; 7 days) inhibits the proliferation of the human neuroblastoma cell line GOTO in a dose- and timedependent manner. α-Carotene (5μM; 48 hours) halts the cell cycle at the G0/G1 phase concomitantly with a reduction in the mRNA expression of the protooncogene N-Myc Western Blot Analysis
	Cell Line:	Lewis lung carcinoma (LLC) cells
	Concentration:	0.5, 1, 2.5μM
	Incubation Time:	24 hours
	Result:	Significantly increased protein expression of TIMP-1 and TIMP-2 in a concentration-dependent manner in LLC cells.
体内研究	α-Carotene (5 mg/kg; oral; twice a week; for additional 3 weeks) alone significantly decreases lung metastasis without affecting primary tumor growth
	Animal Model:	C57BL/6 male mice (4 weeks old; 20-25 g) with LLC cells
	Dosage:	5 mg/kg
	Administration:	Oral; twice a week; for additional 3 weeks
	Result:	Significantly decreased lung metastasis.
