Figure 6. External data and experimental data verify GPT expression of GPT in CRC. (A) GEPIA2 database showing differential expression of GPT in COAD and READ (mRNA level). (B) qRT-PCR showed that GPT was significantly lower in CRC tissues than in adjacent normal tissues. (C) The UALCAN database showed that the low expression of GPT in COAD was correlated with cancer tissues (protein level). (D, E) HPA database showing IHC images of GPT in COAD and colon normal tissues. (F, G) HPA database showing IHC images of GPT in READ and rectal normal tissues.
