The KEGG enrichment pathway shows that the intervention effect of LRP on DPN mice is mainly enriched in histidine metabolism, retrograde endocannabinoid signaling, protein digestion and absorption, choline metabolism in cancer, phenylalanine, tyrosine and tryptophan biosynthesis, glycerophospholipid metabolism, leishmaniasis, long‐term depression, GABAergic synapse, ABC transporters, and primary bile acid biosynthesis (Figure 6D). Here, ABCG2 is linked to cancer.
