ABCG2 and human African trypanosomiasis: Metabolic channels, in the control group and experimental group, show significant differences in metabolic channels with aminoacyltRNA biosynthesis, valine, leucine and tryptophan biosynthesis, ABC transporters, phenylalanine, tyrosine and tryptophan biosynthesis, mutual transformation between the pentose and glucuronic acid, valine, leucine and isoleucine degradation and metabolism of galactose, African trypanosomiasis (African trypanosomiasis), alanine, aspartic acid, and glutamate metabolism.
