For example, HuR expression was positively associated with tumor growth in breast cancer and glioma [32, 33], angiogenesis in lung cancer [34], tumor cell proliferation in non-small cell lung cancer [30], COX-2 expression in colorectal cancer [23], VEGF-A expression in meningioma [24], and HO-1 expression in lung cancer [22]. This evidence concerns the gene ELAVL1 and central nervous system cancer.
