LOXL1 and lung cancer: Using RT-qPCR on a panel of nine lung normal fibroblasts (NFs), 20 human lung cancer-derived primary CAFs, and 30 established NSCLC cell lines, we confirmed that ITGA11 is expressed as a stromal gene, and further showed that LOXL1, like ITGA11, is primarily expressed in CAFs but not in tumor cells or NFs (Figure 1b).
