a Violin plots showing expression of USP28, SREBF2, HMGCS1 and FDFT1 in human Lung adenocarcinoma (ADC) and lung squamous carcinoma (SCC). Data are from TCGA (Firehose legacy). Significance was calculated using Mann–Whitney test. ****p < 0.0001. b Tissue sections from a human NSCLC TMA were stained for USP28, SREBP2 HMGCS1 and SREBP1 by immunohistochemistry. Haematoxilin and eosin (H&E) staining is also shown. Representative images for SCC are shown. c Boxplots showing quantification of USP28, SREBP2, HMGCS and SREBP1 staining in SCC and ADC tumours. Percent positive cells are shown. (SCC: n = 33; ADC: n = 75; ***p < 0.001, Mann-Whitney test). d Pearson correlation between expression of USP28, SREBP2 and HMGCS in SCC tumours (R = Pearson correlation coefficient, p = two tailed t-test). e Kaplan–Meier plots of overall survival of lung cancer patients (N = 1925) dichotomised into ‘high’ and ‘low’ based on median USP28 or SREBF2 expression score. Survival differences were calculated with the log-rank test.
