The expression patterns of FHL2 are different in different cancer types and FHL2 has been shown to be down-regulated in some cancer forms such as prostate cancer (10) and acute myeloid leukemia (11) whilst up-regulated in others such as breast cancer (12), ovarian cancer (13), cervical cancer (14) and colon cancer (8). This evidence concerns the gene FHL2 and acute myeloid leukemia.
