Figure 3. CircRNA NF1-419 influences the gut microbiota composition and cholinergic system. (A) The circRNAs of circ_zfyve1-504, circ_zcchc11-811, circ_zfp652-1147, circ_zfp236-1257, circNF1-419 and circ_zranb1-1575 by reverse transcription polymerase chain reaction in Ganoderma lucidum extractions (LZ) (oral LZ of 50 mg/[kg·d]) and Hericium erinaceus extractions (HE) (oral HE of 50 mg/[kg·d]) treated SAMP8 mice brain samples lasting 24 weeks. (B) Over expression of circNF1-419 in brain could change the gut microbiota at phylum (a) and genus level (b) of SAMP8 mice, see also in
