Expression of Fhit protein during mouse development.
Fhit protein has a putative tumor suppressor function in several types of human and experimental cancers. To assess whether Fhit is involved in fetal development we have examined the distribution of Fhit protein in the 12- through 16-day postcoitum mouse fetus and in postnatal day 0 mouse pups by immunocytochemistry. High levels of Fhit protein were observed in the endodermal derivatives, namely, bronchi, trachea, esophagus, stomach, and intestine, in the 12- to 16-day postcoitum mouse fetus and in the postnatal day 0 pup. Other tissues showed a more restricted pattern of Fhit protein expression. These results suggest that Fhit may play a role in the development of specific tissues during mouse development.
