Since FN1 is well-known as a mesenchymal indicator that has been reported to be involved in PTN in angiogenesis [154,155], the induction of FN1 or PTN mediated by lncRNA OIP5-AS1 in response to doxorubicin might contribute to chemoresistance accompanied by EMT induction and tumor metastasis. The gene discussed is OIP5; the disease is neoplasm.
