Title |
Subject 29 before LCD |
Sample type |
RNA |
|
|
Channel 1 |
Source name |
before LCD
|
Organism |
Homo sapiens |
Characteristics |
source material: study participant, subcutaneous adipose tissue, periumbilical area weight class: weight maintainer time: before LCD
|
Treatment protocol |
Subcutaneous adipose tissue samples from the periumbilical area were obtained by needle aspiration under local anaesthesia after an overnight fast at each of the time points. Biopsy samples were stored at -80°C until analysis.
|
Growth protocol |
8 week low calorie diet (LCD; 3.3 MJ/d; 800 kcal).
|
Extracted molecule |
total RNA |
Extraction protocol |
Total RNA was extracted using the RNeasy total RNA Mini kit (Qiagen).
|
Label |
Cy5
|
Label protocol |
According to Agilent instructions. RNA from study participant labeled with Cy5, RNA from reference pool labeled with Cy3.
|
|
|
Channel 2 |
Source name |
reference RNA
|
Organism |
Homo sapiens |
Characteristics |
source material: commercial pool of human liver, heart, intestine tissue, skeletal muscle RNA
|
Treatment protocol |
Subcutaneous adipose tissue samples from the periumbilical area were obtained by needle aspiration under local anaesthesia after an overnight fast at each of the time points. Biopsy samples were stored at -80°C until analysis.

Description |
Subject 29 before LCD
|
Data processing |
Microarray normalization was carried out by subtracting the median intensity background signal prior to intra-slide Loess normalization of log-transformed data (Goulphar Version 1.1.3 package). All data was then uploaded into the JMP Genomics Version 4.1 platform and further normalized using a quantile inter-slide intensity method.
