TARDBP and neuroblastoma: To test whether various TDP-43 fragments share similar pathological properties in cells, three TDP-43 C-terminal fragments tagged at the amino terminal with enhanced GFP (GFP-TDP208-414, GFP-TDP220-414 and GFP-TDP247-414) were transiently expressed in human neuroblastoma M17 cells and compared to the expression of full-length TDP-43.
