Next, expression levels of TBC1D14 were assessed with immunohistochemistry (IHC) on 74 HNSCC tissue samples (51 cases with LNM and 23 cases without LNM) and paired adjacent normal tissues to address the correlation between TBC1D14 expression and clinical parameters (Fig. 2C, Fig. S1B-C, and Table 1). The gene discussed is TBC1D14; the disease is head and neck squamous cell carcinoma.
