Consistently, TTLL4 expression was higher in HCC samples than in normal tissues across multiple datasets, including TCGA [Fig. 1(d)], GSE14520 [Fig. 1(e)], GSE45436 [Fig. 1(f)], GSE54236 [Fig. 1(g)], GSE62232 [Fig. 1(h)], GSE101685 [Fig. 1(i)], and the TIMER dataset [Fig. 1(j)]. The gene discussed is TTLL4; the disease is hepatocellular carcinoma.
