Phosphocofilin: cofilin co-localization intensity as a predictor of metastatic recurrence

Abstract

Methods and products are provided for determining if a subject having a tumor is at risk of metastasis of the tumor. Specifically, the methods comprise detecting phosphorylated cofilin, and both phosphorylated and non-phosphorylated cofilin; quantifying the phosphorylated cofilin, and the total of phosphorylated and nonphosphorylated cofilin; and determining if a subject having the tumor is likely to experience metastasis of the tumor, based on the ratio of the amount of detected phosphorylated cofilin: total amount of phosphorylated and non-phosphorylated cofilin detected. Further disclosed are the types of tumor metastases that can be determined using the methods provided.
