Photoreceptor cell differentiation

Across TCGA pan-cancer cohorts, RNA activity of the Photoreceptor cell differentiation pathway differs between tumor and matched normal tissue in 9 of the 18 cancer types tested.

The strongest signal is observed in head and neck squamous cell carcinoma (HNSC), where pathway activity is higher in tumor tissue than in matched normal tissue. In most cancer types, this pathway shows higher activity in tumors, although a few cancer types, such as KICH, show the opposite pattern, with lower activity in tumor tissue.

HNSC, STAD, and COAD show the most reproducible tumor–normal differences in pathway activity.

Tumor vs normal pathway activity by lineage

Ranked by sampling consensus. Activity change represents the tumor-versus-normal difference in pathway activity on a log₂ scale. Positive values indicate higher pathway activity in tumor tissue. The reported p-values are derived from the corresponding differential activity tests.
