CAVII expression increases in various cancer types e.g., ovarian, gastric, astrocytomas (tumor formation that begins in astrocytes, cells that provide support to nerve cells), oligodendrogliomas (tumors formed by oligodendrocytes), and mixed oligoastrocytomas (tumors formed by oligodendroglioma and astrocytoma cells), while CAVII expression decreases in CRC (Yang et al., 2015). This evidence concerns the gene CA7 and colorectal carcinoma.
