Exposure to BaP in the SL + BaP group resulted in a significant elevation of serum cancer marker enzymes, including adenosine deaminase (ADA), gamma-glutamyltransferase (GGT), 5′-nucleotidase (CD73), and lactate dehydrogenase (LDH), indicating heightened metabolic activity and potential carcinogenic progression. This evidence concerns the gene ADA and cancer.
