| Extraction protocol |
Genomic DNA (gDNA) and total RNA were isolated in parallel from the same sample using the AllPrep DNA/RNA Mini Kit (Qiagen, Hilden, Germany) following the manufacturer’s instructions. An on-column DNase digestion step was included in the RNA isolation protocol. The final volume of the eluate was 50 μl for gDNA and 30 μl for total RNA. The total RNA samples were isolated for RNA and miRNA sequencing analysis. An aliquot of each total RNA sample was used to determine RNA concentration and purity on the NanoDrop ND-1000 spectral photometer (Peqlab, Erlangen, Germany). All samples were analyzed on the 2100 Bioanalyzer (Agilent Technologies, Santa Clara, USA) using RNA 6000 Nano LabChip Kits (Agilent Technologies, Santa Clara, USA) and RNA integrity number (RIN) was determined. An aliquot of each gDNA sample was used to determine purity and approximate DNA concentration on the NanoDrop ND-1000 spectral photometer (Peqlab, Erlangen, Germany). The TruSeq Custom Amplicon Low Input (TSCA) library preparation protocol was followed. The gDNA samples were additionally quantified using the highly sensitive fluorescent dye-based Qubit® dsDNA HS Assay Kit (ThermoFisherScientific, Karlsruhe, Germany).

For small RNA sequencing, one small RNA sequencing library was prepared from five total RNA samples derived from FFPE tissue samples (sBCC samples 10-14) using the NEBNext® Small RNA Library Prep Kit for Illumina. The kit targets microRNAs and other small RNAs that have a 3' hydroxyl group resulting from enzymatic cleavage by Dicer or other RNA processing enzymes.
Library preparation for the smallRNA samples isolated from FFPE tissue was performed with the TruSeq® Stranded Total RNA incl. Ribo-Zero Gold technology (Illumina, San Diego, USA), according to the manufacturer´s protocol.

| Data processing |
Sequencing of all libraries was performed at a final concentration of 1.8 pM and with a 1% PhiX v3 control library spike-in on the NextSeq500 sequencing system (Illumina, San Diego, USA). For cluster generation and sequencing of all samples, three high output (HO) single-end 75 cycles (1x75bp SE) runs were performed for the small RNA libraries. Sequencing was operated under the control of the NextSeq Control Software V2.1.0 (Illumina, San Diego, USA). The resulting mRNA and totalRNA reads were quality controlled and mapped against the human reference genome. The resulting small RNA reads were quality controlled, mapped against miRBase 21 and the human GRCh38 non-coding RNAs. In sum, the achieved quality values of the NextSeq500 sequencing runs met the manufacturers given specifications (Illumina, San Diego, USA). All data could be used for in depth data analysis.
The CLC Genomics Workbench 9.5.3 (CLC bio, a Qiagen company) was used for in-depth analysis of differential gene expression. Excel 2010 was used for filtering of differentially expressed transcripts and small RNAs. During bioinformatics analysis, the CLC Genomics Workbench adds annotation information to the data, based on the selected reference genome.
