Connective tissue growth factor (CTGF) and transforming growth factor β1 (TGFβ1), cytokines regulating cell proliferation, were found to be decreased in doxorubicin-induced cardiotoxicity and were utilized to evaluate the absence of cardiovascular injury in NSCLC patients in our study [40,41]. The gene discussed is TGFB1; the disease is non-small cell lung carcinoma.
