  Purpose

Main objective : Show that treatment with metformin in patients with type 2 diabetes has an effect on alternative splicing of the insulin receptor.

Secondary objective : demonstrate that the effect on the ratio A/isoform B isoform with discontinuation of treatment with metformin can be réversé by the resumption of metformin treatment.

Primary Outcome Measures:
  • Comparison of expression of isoforms A and B of the insulin receptor using quantitative RT PCR [ Time Frame: inclusion (baseline), 30th days and 60th days ] [ Designated as safety issue: No ]
    comparison of the A isoform (without inclusion of exon 11) and B isoform (with inclusion of exon 11) ratio of the receptor in insulin, during the first period (without metformin) and the second period (with metformin)

Arms Assigned Interventions
Experimental: Arm1

During their visit of consultation on the follow-up to the type 2 diabetes, les patients will be selected on the basis of active metformin treatment at a dose greater than or equal to 1400 mg/day. Patients will have to achieve a 10 ml blood sample. The blood will be processed by Ficoll gradient centrifugation to remove the red cells and isolate circulating leukocytes: this stage will be conducted in the CERITD. Analysis on circulating leukocytes and in particular the quantification of expressions of isoforms A and B of the INSR1 by quantitative RT - PCR gene will be conducted in the laboratory of the Professor Marc Peschanski (unit INSERM 861 I - STEM of Evry).

After inclusion in the study to J0, metformin treatment will be interrupted between J1 and J30, replaced by Januvia 100 mg/day dose, then resumed at J31.

Drug: Metformin
After inclusion in the study to J0, metformin treatment will be interrupted between J1 and J30, replaced by Januvia 100 mg/day dose, then resumed at J31.
