TNFSF14 and thyroid gland carcinoma: Ultimately, we identified a significant association between 5-hydroxymethyl-2-furoylcarnitine and increased risks of thyroid cancer, and found that TNFSF14 can increase the risk of thyroid cancer by elevating Lactosyl-N-palmitoyl-sphingosine (d18:1/16:0) levels and X-12013 levels.
