We then confirmed the expression of CT at the protein level by immunohistochemistry (IHC) in a cohort of 215 formalin-fixed paraffin-embedded (FFPE) lung tumour samples (Supplementary Figure 1a), where up to 20% of ADC and 38% of neuroendocrine tumours (NET) expressed the protein (Table 2). The gene discussed is CALCA; the disease is neuroendocrine neoplasm.
