We also found an interesting link to several cancer-related functions (renal cell carcinoma, small cell lung cancer, colorectal cancer, bladder cancer, N-glycosylation, glycosphingolipid biosynthesis, apoptosis, p53 signaling pathway) for the gut microbiota of F. limnocharis (Figure 6A). The gene discussed is TP53; the disease is urinary bladder carcinoma.
