In nonobese subjects, C/EBP-α expression seems to be correlated with adipogenic transcription factors (significant positive correlation with PPAR-γ and PGC-1α (p < 0.05)), while in nonobese CRC patients, C/EBP-α expression was more correlated with glucose (significant correlation with homeostasis model assessment of insulin resistance (HOMA-IR) and glucose levels (p < 0.05)) and lipid metabolism (positive trend with triglycerides and negative correlation with HDL (p < 0.05)). Here, PPARGC1A is linked to colorectal carcinoma.
