SLC34A2 and lung carcinoma: Additionally, Wu et al. 50 demonstrated that F-circrSR1 and F-circrSR2 originated from the same fusion gene solute carrier family 34 member 2 and reactive oxygen species proto-oncogene 1 (SLC34A2-ROS1), both of which promoted the migration of lung cancer cells, but did not affect cell proliferation.
