As an example, SLC29A1 (hENT1) shows a substantially decreased proportion of the upstream TSS (i.e., PSI value; Fig. 5C, D), due to the elevated expression of the shorter transcript ENST00000472176 (Fig. 5D), which may explain the finding that SLC29A1 has a significantly higher expression level in gastric tumor tissue compared with normal stomach tissue45. The gene discussed is SLC29A1; the disease is gastric neoplasm.
