1 Vitamin A is a potent inducer for liver/bone/kidney alkaline phosphatase (L/B/K ALP) in a variety of tissues. Vitamin A PDZ and LIM domain 3 Rattus norvegicus
2 However, the evidence for induction of L/B/K ALP by vitamin A in small intestine is limited. Vitamin A PDZ and LIM domain 3 Rattus norvegicus
3 In this study, we investigated the influence of vitamin A on L/B/K ALP expression in rat small intestinal crypt IEC-6 cells and fetal rat small intestine. Vitamin A PDZ and LIM domain 3 Rattus norvegicus
4 Treatment of IEC-6 cells with all-trans retinoic acid (RA) increased the levels of activity, protein and mRNA of L/B/K ALP, whereas enterocyte-specific proteins, including intestinal ALP, sucrase-isomaltase and glucose transporter-2, were not induced. Tretinoin PDZ and LIM domain 3 Rattus norvegicus
5 Treatment of IEC-6 cells with all-trans retinoic acid (RA) increased the levels of activity, protein and mRNA of L/B/K ALP, whereas enterocyte-specific proteins, including intestinal ALP, sucrase-isomaltase and glucose transporter-2, were not induced. Tretinoin PDZ and LIM domain 3 Rattus norvegicus
6 Our results suggest that vitamin A may be an important regulator for L/B/K ALP expression in fetal rat small intestine as well as in IEC-6 cells. Vitamin A PDZ and LIM domain 3 Rattus norvegicus
