In the present study, we found that PCAT6 may be co-expressed with LIPT1, LIPT2, SLC31A1, GLS, etc., by co-expression analysis of copper death genes and lncRNA in HCC; however, how exactly the two interact with each other and how they affect copper death still needs further experimental investigation. The gene discussed is SLC31A1; the disease is hepatocellular carcinoma.
