| Title |
Subject 2_t=30days_resveratrol |
| Sample type |
RNA |
| |
|
| Source name |
after 30 days intervention with resveratrol
|
| Organism |
Homo sapiens |
| Characteristics |
ethnic background: Caucasian
gender: male
age: 45-65 years
tissue: vastus lateralis muscle
|
| Treatment protocol |
The design of the study was a randomized cross-over design with two different treatments: placebo and resVida (150mg/day trans-resveratrol). Subjects were instructed to take the first supplement on the day after baseline measurements (d1) and the last supplement in the evening on day 29. In the morning of day 30, after a 36h in the respiration chamber, a muscle biopsy was taken, which was followed by the withdrawal of a fasting blood sample.

| Growth protocol |
Ten healthy obese men (age 45–65 years; BMI 30-35 kg/m2) participated in a double-blind randomized cross-over study. Exclusion criteria were unstable body weight (weight gain or loss > 3 kg in the last three months), total body fat (%) < 25%, fasting plasma glucose > 6.1 mmol/l, hemoglobin < 7.8 mmol/l, engagement in programmed exercise > 2 hours total per week, impaired kidney and/ or hepatic function, first- or second-degree family member with type 2 diabetes mellitus, any medical condition requiring treatment and/or medication use, intake of dietary supplements except vitamins and minerals, unwilling to restrict high-resveratrol-containing foods, current alcohol consumption > 20 grams/day, participation in another biomedical study within 1 month before the first screening visit, a contraindication to MRI scanning. All subjects were informed about the nature of the study and written informed consent was obtained before study participation. The local Medical Ethical Committee of Maastricht University Medical Centre approved the study protocol.

| Extracted molecule |
total RNA |
| Extraction protocol |
Skeletal muscle biopsies were taken in the morning of day 30 after an overnight fast. Biopsies were obtained from the vastus lateralis muscle under local anesthesia of the skin and fascia using the Bergström method with suction, cleaned from any visible fat and blood, immediately frozen in isopentane at its melting point, and stored at −80C until analysis.

| Label |
biotin
|
| Label protocol |
The Affymetrix GeneChip WT Sense Target Labeling and Control Reagents kit (P/N 900652) was used for the preparation of labelled cDNA from 100ng of total RNA without rRNA reduction. A detailed description can be found in the User Manual, Chapter 3 (P/N 701880, revision 5).

|
| Hybridization protocol |
The Affymetrix GeneChip Human Gene 1.1 ST 24-array plate consists of 24 single Gene 1.1 ST arrays arranged into the standard 96 well plate format. For this experiment 20 arrays were used. Array hybridization, washing and scanning were performed on a GeneTitan Instrument according to the manufacturer’s recommendations.
|
| Scan protocol |
Arrays were scanned on an Affymetrix GeneTitan instrument.
