LINC01056 and hepatocellular carcinoma: Phospho-Erk was previously reported as a predictive marker of the sorafenib response in HCC patients, and we observed that Linc01056 expression was positively correlated with the phospho-Erk level in HCC tissues [35], indicating the clinical association of Linc01056 expression with the sorafenib response in HCC patients (Fig. 6g).
