HIF1A and posterior cortical atrophy: In line with the observation of high levels of HIF-1α and OATP staining in human PCa samples, we surveyed HIF-1α and OATP2B1 protein expression in multiple types of paired cancer-adjacent normal and cancerous canine (breast, duodenal, liver, lung, colon and epidermis sarcoma) and human (lung, colon, prostate, breast, liver and kidney) tissues by double quantum dots labeling (QDL) analysis.
