摘要:: It is generally believed that under normal conditions only B lymphocytes express immunoglobulin. Interestingly, our previous work demonstrated that epithelial cancer tissues and cancer cell lines also express Ig alpha heavy chain. So we further analyzed the potential function of cancer-derived Ig alpha heavy chain. Here we show that blockade of cancer-derived Ig alpha suppressed the growth and viability of cancer cells. And cancer-derived Ig alpha promotes the malignant proliferation ability of cancer cells. Furthermore, we demonstrated that Ig alpha protein increases the access percentage of S phase from the early mitosis of synchronized cancer cells. Our findings support the important role of cancer-derived Ig alpha as a growth promoter of cancer cells, and reveal a novel molecular mechanism for growth and proliferation of cancer cells.
