| Title |
H9_DP105PR02: Pancreatic islet sample from partially pancreatectomized patient |
| Sample type |
RNA |
| |
|
| Source name |
Pancreatic islet sample by laser capture microdissection
|
| Organism |
Homo sapiens |
| Characteristics |
age (years): 72
gender (m/f): M
body mass index (bmi): 28.2284
fasting glucose (mmol/l): 9.42
diabetes status (nd (non-diabetic), t2d (type 2 diabetic), igt (impaired glucose tolerance, t3cd (type 3 diabetic)): T2D

|
| Extracted molecule |
total RNA |
| Extraction protocol |
Pancreatic islets within resected pancreas specimens were isolated by laser capture microdissection with Zeiss Palm MicroBeam system
|
| Label |
biotin
|
| Label protocol |
10 - 25 ng total RNA was amplified using the Ovation RNA Amplification System V2 and subsequently labelled with Biotin using the Encore™ Biotin Module following the manufacturer's instructions (NuGEN Technologies, San Carlos, CA, USA).
|
| |
|
| Hybridization protocol |
3.75µg cDNA per sample were hybridized to Affymetrix HG-U133 Plus 2.0 GeneChips (Affymetrix) for 16-18 hours at 45°C and 60 rpm in a rotating hybridization oven (Hybridization Oven 640, Affymetrix). The array was subsequently washed and stained with a fluidics station (GeneChip® Fluidics Station 450, Affymetrix) following the EukGe_WSv4_450 fluidics protocol for eukaryotic 3´-expression arrays.
|
| Scan protocol |
Arrays were scanned using GeneChip Scanner 3000 7G (Affymetrix).
|
| Data processing |
Primary data analysis was performed with Affymetrix software GeneChip Operating System (GCOS) v1.4. Transcriptomic data were summarized and normalized with the Robust Multichip Analysis (RMA) using a software package (Array Studio; Omicsoft Corp., Cary, NC, USA). Batch correction of microarray data was performed using the R/Bioconductor package ComBat (Johnson et al., 2007).
Differential expression analysis comparing T2D and ND in OD or PPP cohorts:
Empirical Bayes moderated t statistics and corresponding p-values were computed using the Limma package in R correcting for age and sex covariates. P values were adjusted for multiple comparisons using the Benjamini Hochberg procedure.
