WASF2 and hematopoietic and lymphoid system neoplasm: It has been reported that WASF1 is highly expressed in a variety of tumor cells such as prostate cancer [61], epithelial ovarian cancer [62] and blood cancer cells [63], and WASF2 is also highly expressed in melanoma cells [64]; therefore, high expression of WASF family genes is considered a marker gene for tumor progression.
