SLC43A2 and hepatocellular carcinoma: Additionally, solute carrier family 43 member 2 (SLC43A2), a methionine transporter, is associated with higher levels of CD8+ T cells, higher markers of T cell exhaustion and lower levels of naive CD8+ T cells, suggesting that SLC43A2 may regulate immune‐related genes, leading to CD8+ T cell exhaustion and impacting the TME and prognosis of HCC.186
