Factors affecting the retinoic acid modulated expression of mucin mRNA in rat tracheal cultures were studied. Actinomycin D had no effect on mucin mRNA in cultures grown with retinoic acid (RA+). The(More)
Rabbit tracheal explants, exposed to burning pine wood smoke, were cultured in a chemically defined medium with and without retinoic acid (±RA). Exposures of 15–20 minute led to RA-independent(More)
