Western blot analysis of 37/67 kDa laminin receptor. A) Protein expression of 37/67 kDa laminin receptor (37/67LR) of small intestinal mucosa samples of vitamin D receptor knockout (VDR-KO) and wildtype (WT) mice are represented as means ± s.d. (n = 6). *Significantly different from WT mice (p < 0.05, Student’s t-test). B) Representative immunoblot of 37/67LR and GAPDH from small intestinal mucosa samples of VDR-KO and WT mice.
