Abstract Chemotherapy resistance is one of the major obstacles limiting the success of cancer drug treatment. Among the mechanisms of resistance to chemotherapy treatment, there are those closely related to P-Glycoprotein, multidrug resistance-related protein, glutathione S-transferase pi and topoisomerase-II. Lin28 is a highly conserved RNA-binding protein, it consists of a cold shock domain and retroviral-type (CCHC) zinc finger motifs. In previous preclinical and clinical studies, positive Lin28 expression in cancer cells was correlated with decreased sensitivity to chemotherapy. And Lin28 could mediate cancer chemotherapy resistance via regulation of miR107 and Let-7 MiRNA. This article reviews current knowledge on predictive value of Lin28 in response to chemotherapy. Better understanding of its role may facilitate patient's selection of therapeutic regimen and lead to optimal clinical outcome.
