In a Turkish case-control study by Erden et al., 2014 [19], the relationship between chronic obstructive pulmonary disease (COPD) and BPA, C-reactive protein (CRP), MDA, and total thiol levels (all in serum) was investigated (COPD: n = 50; 61.6 ± 11.2 years, 44 males/6 females); controls: n = 33; 57.6 ± 11.1 years, 29 males/4 females). The gene discussed is CRP; the disease is chronic obstructive pulmonary disease.
