Thus, after 4h10 exposure to pCD, the expression of ARHGAP26 encoding a protein participating in endocytosis and associated with cancer was upregulated, and TRIM16L involved in cell growth, differentiation and pathogenesis, as well as CEBPD encoding the protein involved in immune and inflammatory responses were downregulated, suggesting the potential impacts of these CDs on immunity, surfactant production [26] and lung carcinogenesis [27]. The gene discussed is ARHGAP26; the disease is cancer.
