(16) studied the effects of amino acid taurine in attenuating lung fibrosis in C57BL/6 mice treated with a single dose of 14-Gy thoracic radiation and found that amino acid taurine significantly decreased the serum TGF-β1 levels and Hyp content at 14 weeks post-irradiation. Here, TGFB1 is linked to pulmonary fibrosis.
