Effects of retinol deficiency and hyperoxia on collagen gene expression in rat lung.

Exposure to hyperoxia results in lung injury and a decrease in lung collagen. Retinol is known to influence collagen gene expression, and retinol deficiency has been shown to potentiate hyperoxic lung injury. To investigate the combined effects of retinol deficiency and hyperoxia on lung collagen expression, retinol-deficient rats were exposed to acute… CONTINUE READING
