TG and cerebellar ataxia: As shown in Figure 5, the most enriched pathways in CPT versus MC group were glycolysis/gluconeogenesis, spinocerebellar ataxia, galactose metabolism, histidine metabolism, IL-17 signaling pathway, protein digestion and absorption, estrogen signaling pathway, thyroid hormone signaling pathway, thyroid hormone synthesis, arginine and proline metabolism (consisting of 13, 14, 7, 5, 8, 9, 16, 9, 8 and 8 proteins, respectively).
