Outline of Final Research Achievements |
As a result of exome analysis aiming at identification of the causative gene of the insulin resistance family, PIK3R1 gene c.1945C> T mutation was identified. In order to clarify the function of this mutation, we established iPS cells from probands and induced differentiation into hepatocytes. Compared with hepatocytes derived from healthy person-derived iPS cells, Akt phosphorylation upon addition of insulin was significantly suppressed, suggesting that the PIK3R1 abnormality suppresses the insulin action.
