A number of studies have shown that the silence of KIAA1429 expression inhibited cell proliferation in many types of cancer cells, including liver cancer [7,19], gastric cancer [16,20], osteosarcoma [21], Ewing sarcoma [22], lung cancer [13,23,24], colorectal adenocarcinoma [11], ovarian cancer [9], and multiple myeloma [14]. This evidence concerns the gene VIRMA and AL amyloidosis.
