Fig. 6: Correlation analysis among altered serum metabolites, sucrose preference and proteins.

A The heatmap depicted the relationships between the sucrose preference, proteins and metabolites. B Associations of C16-Ceramide with sucrose preference, PSD-95, GluA1 and p-TrkB/TrkB in the PFC and p-TrkB/TrkB in the kidney. PFC, prefrontal cortex.
