Alpha-carotene inhibits metastasis in Lewis lung carcinoma in vitro, and suppresses lung metastasis and tumor growth in combination with taxol in tumor xenografted C57BL/6 mice.[Pubmed:25736483]
J Nutr Biochem. 2015 Jun;26(6):607-15.
This study aimed to investigate the anti-metastatic activity of alpha-Carotene (AC) in Lewis lung carcinoma (LLC) and in combination with taxol in LLC-xenografted C57BL/6 mice. Cell culture studies reveal that AC significantly inhibited invasion, migration and activities of matrix metalloproteinase (MMP)-2, -9 and urokinase plasminogen activator but increased protein expression of tissue inhibitor of MMP (TIMP)-1, -2 and plasminogen activator inhibitor (PAI)-1. These effects of AC are similar to those of beta-carotene at the same concentration (2.5 muM). AC (2.5 muM) also significantly inhibited integrin beta1-mediated phosphorylation of focal adhesion kinase (FAK) which then decreased the phosphorylation of MAPK family. Findings from the animal model reveal that AC treatment (5m g/kg) alone significantly decreased lung metastasis without affecting primary tumor growth, whereas taxol treatment (6 mg/kg) alone exhibited significant inhibition on both actions, as compared to tumor control group. AC treatment alone significantly decreased protein expression of integrin beta1 but increased protein expression of TIMP-1 and PAI-1 without affecting protein expression of TIMP-2 and phosphorylation of FAK in lung tissues, whereas taxol treatment alone significantly increased protein expression of TIMP-1, PAI-1 and TIMP-2 but decreased protein expression of integrin beta1 and phosphorylation of FAK. The combined treatment produced stronger actions on lung metastasis and lung tissues protein expression of TIMP-1, TIMP-2 and PAI-1. Overall, we demonstrate that AC effectively inhibits LLC metastasis and suppresses lung metastasis in combination with taxol in LLC-bearing mice, suggesting that AC could be used as an anti-metastatic agent or as an adjuvant for anti-cancer drugs.
Potent preventive action of alpha-carotene against carcinogenesis: spontaneous liver carcinogenesis and promoting stage of lung and skin carcinogenesis in mice are suppressed more effectively by alpha-carotene than by beta-carotene.[Pubmed:1423303]
Cancer Res. 1992 Dec 1;52(23):6583-7.
Although beta-carotene has been considered to be a key cancer preventive agent in green and yellow vegetables, other types of carotenoids, such as alpha-Carotene, may also contribute to anticarcinogenic action, since these carotenoids usually coexist with beta-carotene and are detectable in human blood and tissues. In this study, we compared the inhibitory effect of natural alpha-Carotene, obtained from palm oil, with that of beta-carotene on spontaneous liver carcinogenesis in C3H/He male mice. The mean number of hepatomas per mouse was significantly decreased by alpha-Carotene supplementation (per os administration in drinking water at a concentration of 0.05%, ad libitum) as compared with that in the control group (P < 0.001, Student's t test). On the other hand, beta-carotene, at the same dose as alpha-Carotene, did not show any such significant difference from the control group. Furthermore, we also compared the antitumor-promoting activity of alpha-Carotene with that of beta-carotene against two-stage mouse lung carcinogenesis (initiator, 4-nitroquinoline 1-oxide; promoter, glycerol). alpha-Carotene, but not beta-carotene, reduced the number of lung tumors per mouse to about 30% of that in the control group (P < 0.001, Student's t test). The higher potency of the antitumor-promoting action of alpha-Carotene compared to beta-carotene was confirmed in other experimental systems; e.g., alpha-Carotene was also found to have a stronger effect than beta-carotene in suppressing the promoting activity of 12-O-tetradecanoylphorbol-13-acetate on skin carcinogenesis in 7,12-dimethylbenz[a]anthracene-initiated mice. These results suggest that not only beta-carotene, but also other types of carotenoids, such as alpha-Carotene, may play an important role in cancer prevention.
