Beyond vacuolar pathology: Multiomic profiling of Danon disease reveals dysfunctional mitochondrial homeostasis.

Abstract

Figure S1: Visual representation of the interaction network of dysregulated proteins. String analysis was carried out separately for increased and decreased proteins. Increased proteins (left panel) show a strong functional interdependence for mitochondrial proteins, whereas decreased proteins (right) form a cluster of proteins involved in protein translation and degradation. The interaction network was built with String 10 DB. Figure S2: (A) Protein investigation: DD-patients (n=2) versus Controls (n=3) => 1,606 unique proteins included from which on average 2 or more peptides were identified in the DD-patient as well as in the control group. Rows are centered; unit variance scaling is applied to rows. Both rows and columns are clustered using correlation distance and average linkage. For all proteins an average of at least 2 peptides had to be identified in each sample. 184 rows, 5 columns, T-test between DD-patients and Controls p<0.05 (B) mRNA investigation: DD-patients (n=2) versus Controls (n=4) => 14,334 mRNA species included. Rows are centered; unit variance scaling is applied to rows. Both rows and columns are clustered using correlation distance and average linkage. 543 rows, 6 columns. FPKM>0.1, T-test between DD-patients and Controls p<0.001. Figure S3: Co-localization of mitochondria with the activated p62-pathway. Immunofluorescence with co-localization (yellow) of mitochondrial protein COX-II (red) and p62 (SQSTM1; green). DAPI staining of nuclei in blue (magnification x400). Table S1.
