Abstract

OBJECTIVE: To observe the expression changes of Follistatin (FSN) and follistatin-like 3 (FSRP) mRNA, both of bone morphogenetic protein-4(BMP4) antagonists, in mice lung tissue under different hypoxic time and its relation with BMP4.

METHODS: Thirty BMP4+/+ C57BL/6J wild type mice were randomly divided into normoxic control group, and 4 groups including 1 day, 3 days, 7 days and 21 days under hypoxic condition. The hypoxic animal model was established by exposing the mice to hypoxic condition for different time. The expressing level of FSN and FSRP mRNA in lung tissues were measured by Quantitative Real-Time PCR.

RESULTS: FSN and FSRP mRNA increased in hypoxic 1 day group as (28.0 ± 9.4) and (2.0 ± 0.4), in hypoxic 3 day group, FSN mRNA increased by (6.3 ± 3.2) and FSRP mRNA by (1.67 ± 0.7) (P < 0. 05). Compared with the normoxic group (1.77 ± 0.36) and (1.22 ± 0.15) (P < 0. 01), FSN and FSRP mRNA up-regulated in hypoxic 7 day group. The positive degree of FSN and FSRP mRNA in hypoxic 21 day group were (1.04 ± 0.27) and (0.85 ± 0.10) (P < 0. 05). In normoxic 1 day group, FSN mRNA of lung tissues of BMP4+/- C57BL/6J mice was (0.95 ± 0.05); FSRP mRNA was (1.11 ± 0.03) (P < 0. 05). In BMP4+/- C57BL/6J mice lung tissues, FSN mRNA were (1.10 ± 0.40) (P < 0. 05); FSRP mRNA were (0.85 ± 0.18).

CONCLUSIONS: The expression of FSN and FSRP mRNA in hypoxic 1;3;7 day mice lung tissues increased obviously, and FSN may play an important role in the hypoxic pulmonary hypertension through BMP4.
