By KEGG analysis, when AADAC was overexpressed, a total of 1205 genes participated in 36 signaling pathways that may play an important role in the biofilm synthesis and proliferation of tumor cells, such as glycerophospholipid metabolism, fatty acid degradation, fat digestion and absorption, tyrosine metabolism and phenylalanine metabolism (Table 2). The gene discussed is AADAC; the disease is neoplasm.
