Expression and distribution of SLC25A11 in lung cancer and malignant melanoma tissue samples. (a) Tissue microarray was performed to determine the expression of SLC25A11 in normal lung tissues and lung cancer samples. A-1: Normal lung tissue showing no staining (×200; scale bar, 200 μm); A-2: Weak, A-3: Moderate, and A-4: Strong expression of SLC25A11 in lung cancer samples (×400; scale bar, 60 μm). (b) Percent distribution (graph) and SLC25A11 expression patterns in normal and cancer samples (Table) according to histologic subtypes. Statistical significance compared with normal lung tissues was determined by Fisher's exact test. (c) The expression patterns of SLC25A11 in malignant melanoma were determined by IHC. A-1: Weak, A-2: Moderate, A-3: Strong (×400; scale bar, 60 μm). (d) Percent SLC25A11 expression in normal skin and malignant melanoma samples. (Statistical significance was calculated by Fisher's Exact test. ***p < .001, **p < .01, *p < .05).
