TY - JOUR T1 - Lactase activity is under hormonal control in the intestine of adult rat. JF - Gut JO - Gut SP - 648 LP - 652 DO - 10.1136/gut.24.7.648 VL - 24 IS - 7 AU - F Raul AU - R Noriega AU - E Nsi-Emvo AU - M Doffoel AU - J F Grenier Y1 - 1983/07/01 UR - http://gut.bmj.com/content/24/7/648.abstract N2 - In the adult rat, starvation during 48 hours led to a three fold increase of lactase specific activity in the intestinal brush border membranes. Thyroxine injection during the three days before death (0.5 micrograms/g daily) inhibited the stimulation of lactase activity induced by starvation without modifying sucrase activity whereas hydrocortisone injections (25 micrograms/g daily) or thyroidectomy did not modify the stimulatory effect of starvation on lactase activity. These results suggests a specific hormonal control of intestinal lactase activity in the rat. ER -
