A more than 5-year clinical follow-up of 22 INSIP and 25 IPF patients provided a data matrix of eight parameters including gender, age at disease diagnosis, smoking, chronic toxin exposure, survival time, whether the patient was deceased (death), as well as the levels of TGF-β1 and BMP3 proteins in lung tissue biopsy specimens. The gene discussed is BMP3; the disease is idiopathic pulmonary fibrosis.
