Summary

Type 2 diabetes and obesity are both multifactorial diseases resulting from gene-environment interactions. However, this interaction, as well as the specific effect of each polymorphism, remains poorly understood. We now proposed a prospective cohort study to improve our understanding of the influence of phenotypic characteristics on gene expression in tissues involved in glucose and/or lipid metabolism by collecting different biological samples.

Eligibility

Age: 18 Years – 65 YearsHealthy volunteers accepted
Inclusion Criteria:

* Age between 18 and 65 years
* Indication of abdominal surgery requiring a laparotomy or laparoscopy for bariatric surgery, cholecystectomy, or parietal surgical
* Phenotype corresponding to one of the following four cases :

  1. Body Mass Index ≥ 35 kg/m2 and diabetes defined by a fasting blood glucose ≥ 7 mmol/l and/or ≥ to 11.1 mmol/l, 120 minutes after ingestion of glucose (hyperglycemia caused by oral route)
  2. Body Mass Index ≥ 35 kg/m2 with intolerance glucose defined by a fasting blood glucose\> 6 mmol/L and \<7 mmol/l and/or\> 7.8 mmol/l and \<11.1 mmol/l , 120 minutes after ingestion of glucose (hyperglycemia caused by oral route)
  3. Body Mass Index ≥ 35 kg/m2 without diabetes defined by a blood glucose ≤ 6 mmol/L and / or ≤ 7.8 mmol/l, 120 minutes after ingestion of glucose (hyperglycemia caused by oral route)
  4. Body Mass Index \<27 kg/m2 without diabetes defined by a blood glucose ≤ 6 mmol/L and / or ≤ 7.8 mmol/l, 120 minutes after ingestion of glucose (hyperglycemia caused by oral route)

5)27 \<Body Mass Index \<35 kg/m2 without diabetes defined by a blood glucose ≤ 6 mmol/L and / or ≤ 7.8 mmol/l, 120 minutes after ingestion of glucose (hyperglycemia caused by oral route)

Exclusion Criteria:

* unable to receive clear information
* refusal to sign the consent form
* pathology associated judged by the surgeon, may increase the risk of adverse events related to sampling tissue
