The effects of LDLR knockdown on the gut microbiota species composition in aging mice. (A) Venn: Different colors represent different groups, overlapping numbers represent the number of species common to multiple groups, and non-overlapping numbers represent the number of species unique to the corresponding groups, (B) Circos groups and species relationship diagram: The left half circle represents the species composition in the groups; The right half circle shows the proportion of species in different samples at the taxonomic level. Acon adult mice with empty vector, ALKd adult mice with LDLR knockdown, Ocon old mice with empty vector, OLKd old mice with LDLR knockdown (Each group = 6).
