Description:
Pediatric patients aged 3-18 years, with suspected or established IBD (CD and UC) were recruited to a mono-centric IBD cohort study (recruitment 2019 – 2022, Dr von Hauner Children’s Hospital, LMU Munich) and followed prospectively. The goal of our study was to collect samples from patients that achieved Endoscopic healing (EH) after active IBD. Biopsies (directly transferred into RNAlater™ Invitrogen) were collected at baseline ileocolonoscopy (timepoint = 1) and follow-up ileocolonoscopy/sigmo...     »
Method of data assessment:
Host RNA was isolated from RNAlater™ preserved biopsy samples. Biopsies were mechanically disrupted (in a guanidine thiocyanate and β-mercaptoethanol solution) using the gentleMACS™ dissociator. RNA was isolated using the AllPrep DNA/RNA-isolation kit (Qiagen). Our protocol resulted in high quality RNA (RIN > 7 and >300 ng/µl). RNA was stored at -80°C until preparation of RNA-seq libraries (NEBNext Ultra II RNA Library Prep Kit; mRNA enrichment) and Illumina NovaSeq 6000 sequencing (2x150 paired end). We used FastQC (v0.11.9) and Trim Galore (v0.6.6) for quality assessment and removing low-quality reads. High-quality reads were aligned to the human reference genome GRCh38 using STAR (v2.7.9a) and quantified using featureCounts (v2.0.2). Genes with a count lower than 5 were removed. DEseq2 (v1.42.0) was used to run variance stabilizing transformation and to identify differentially expressed genes (DEGs) in pairwise comparisons (corrected for batch, location, age at endoscopy [groups: <6, 6 – 12, and >12] and gender).
