We also detected an increase within Clusters 3 and 5 in the human genes STC1 and FLT4, which we found to be differentially expressed genes in our previous bulk RNA‐seq report of human KS lesions and observed a 35‐fold increase in STC1 RNA levels upon KSHV infection in primary lymphatic endothelial cells [4]. Here, STC1 is linked to Kaposi's sarcoma.
