β-Carotene down-regulates the COX-2 but up-regulates the p21 mRNA level and protein expression in a time dependent manner[3]. β-Carotene significantly increases the percentage of early apoptosis and the effect was partly attenuated by pre-incubation with GW9662 (HY-16578) or GSH (HY-D0187...
If having a natural tan is your goal, eating foods high in beta-carotene can increase skin pigmentation. Foods high in beta-carotene include dark leafy green vegetables like kale and spinach, cantaloupe, butternut squash, carrots, sweet potatoes, red and yellow peppers, and apricots. Herbs such...

Carotenoids are natural pigments which are synthesized by plants and are responsible for the bright colors of various fruits and vegetables. There are several dozen carotenoids in the foods that we eat, and most of these carotenoids have antioxidant activity. 尾-carotene has been best studied since...

The dosage and usage information is provided. The possible adverse reactions or side effects of the drug, warn...
The Caco-2 cells were incubated with test solutions containing different amounts of ferrous chloride (1050 M) and -carotene (0.32.5 M) incorporated in synthetic micelles. In the absence of iron, cellular accumulation of -carotene from synthetic micelles was proportional (r2=0.97, P <0.001) to...
