|title=Age-related decrease of IF5/[[BTG4]] in oral and respiratory cavities in mice.

|abstract=An IF5 cDNA was isolated by expression cloning from a mouse oocyte cDNA library. It encoded a protein of 250 amino acids, and the region of it encoding amino acids 1-137 showed 86.8% alignment with the anti-proliferative domain of BTG/TOB family genes. This gene is also termed [[BTG4]] or PC3B. Transiently expressed IF5/[[BTG4]] induced alkaline phosphatase activity in human embryonic kidney (HEK293T) and 2T3 cells. IF5/[[BTG4]] mRNA was detected by reverse transcription polymerase chain reaction in pharynx, larynx, trachea, oviduct, ovary, caput epididymis, and testis, but not in lung, intestine, or liver. Immunohistochemistry showed the IF5/[[BTG4]] protein to be present in epithelial cells of the tongue, palate, pharynx, internal nose, and trachea. Both protein and mRNA levels of IF5/[[BTG4]] were reduced by aging when comparing 4-week-old mice with 48-week-old mice. Our findings suggest that IF5/[[BTG4]] may be an aging-related gene in epithelial cells.
