In order to explore repurposable common drugs for both T2D and CRC, we identified both diseases causing top-ranked 8 sKGs (CD44, COL18A1, CLDN5, PLS3, PTK2, THBS1, CAV1, and EFEMP1) as the drug targets through transcriptomics analysis. The gene discussed is PTK2; the disease is type 2 diabetes mellitus.
