After tumor resection, the tumor metastatic activity and survival rate of mice treated with 1× PBS, naïve TCL (extracted from untreated 4T1 cells), SK-TCL (extracted from SK-treated 4T1 cells) and SK-4T1(hn)-TCL (extracted from SK-treated 4T1-hnRNPA1 cells) were compared (Figure 5a). The gene discussed is HNRNPA1; the disease is neoplasm.
