In HNSCC tumors from male AA and NHW combined, there were significantly higher levels of 16:0, 22:0, 24:1, 24:0, and 26:0 ceramides (Figure 1Q); 16:0 and 24:0 monoHexCer (Figure 1R); 26:1 SM (Figure 1S); and 16:0, 24:1, and 24:0 lacCer (Figure 1T), but no significant differences in the levels of So, Sa, So-1-P, and Sa-1-P (Figure 1Y). The gene discussed is STAG1; the disease is head and neck squamous cell carcinoma.
