Vitamin D deficiency activates pulmonary RAS. (A) Immunofluorescence staining of the lung tissue with renin after two months of vitamin D deficiency. Original magnification: 200×. (B) Relative mRNA expressions of RAS components by real-time PCR. *P < 0.05, **P < 0.01, ***P < 0.001 Ctrl versus VDD group of the same age (n = 5–6 in each group). (C) Serum angiotensin II concentration in the mice after 2 months and six months of vitamin D deficiency. ***P < 0.001 Ctrl versus VDD group of the same age (n = 5–6 in each group). Agt: angiotensinogen; Ang: angiotensin; ACE1: angiotensin converting enzyme 1; AT1R: angiotensin type 1 receptor; Ctrl: control; VDD: chronic vitamin D deficiency; 2 m: 2 months; 6 m: 6 months. Statistics: Independent-sample two-tailed t-test.
