CPT1A and colorectal carcinoma: The distribution of CPT1A in tumor cells and CAFs by serial immunohistochemistry indicated that CPT1A was upregulated in CAFsPM than CAFsnPM which was identified by the a‐SMA + cell coverage (red areas), whereas expression of CPT1A was significantly lower in PM‐CRC tumor cells, compared with those in non‐PM‐CRC tumor cells(Fig. 3E and Fig. S3B).
