Conversely, only 8 SLCs were upregulated (log2FC ≥ 2, p ≤ 0.05) in more than 14 tumors reaching 20 for SLC27A2. Among these, SLC44A4, SLC34A2, and SLC6A14 showed log2FC ≥ 4 in at least 9 tumor types and log2FC ≥ 6 in more than 5 tumors (Figure 1B; Supplementary Table S2). Here, SLC34A2 is linked to neoplasm.
