Zhao et al. [99] found that cancer-associated fibroblasts upregulate LncRNA DLEU1, which acts as an oncogene by binding with ZFP36 to epigenetically downregulate ATF3 expression, promoting iron death resistance in GBM, thereby providing a potential biological marker for diagnosing iron death resistance in GBM. The gene discussed is DLEU1; the disease is glioblastoma.
