PCBP1 and choriocarcinoma: The results are also well consistent with observations that PCBP1 expressions are usually downregulated in some human tumors, including liver [19], gall bladder [23], choriocarcinoma [22], colon and lung cancers [17], as well as in metastatic cervical cancer [21] and metastatic breast cancer cells [43].Then, we found that the expression of PCBP1 in 12 AML patients in complete remission after intensive chemotherapy was also markedly increased, compared to that at their initial diagnosis, suggesting the dysregulated expression of PCBP1 is consistent with cancer progression.
