We found that for GBP5, LINC00707 and SLC4A11, the effect of BPA exposure is minimal with a potential positive bias in GBP5 and negative bias in LINC00707 and SLC4A11. By contrast, KRT4 was shown to be strongly and negatively impacted by BPA exposure, suggesting that BPA can alter the predictive outcome of KRT4. Of note, KRT4 shows a particular behaviour exhibiting no significant change in expression between normal and primary tumours but showing a strong positive patient outlook upon down-regulation. The gene discussed is SLC4A11; the disease is neoplasm.
