title: [Gestational and non-gestational factors for perinatal programming of insulin resistance].
abstract: Insulin resistance is well known problem in type 2 diabetes mellitus (T2DM). Various factors play roles in the mechanisms of prenatal programming of insulin resistance. Gestational or non-gestational factors are illustrated in the present paper. Adipocytes (fat cells) produce at least 50 proteins (adipokines; peptides, cytokines, etc.), and a large part of them are involved in prenatal development of insulin resistance. The role of pro-inflammatory cytokines as the tumor necrosis factor 1 (TNF alpha), interleukin-6 (IL-6) and interleukin-1 beta (IL-1 beta) is documented. Leptin from adipocytes as well as from the placenta is involved in pathology of metabolism and plays a role as a gestational factor for the prenatal insulin resistance and the risk for T2DM. Epigenetic mechanisms as the methylation of DNA and histones, the acetylation of histones are documented for prenatal development of insulin resistance. Epigenetic modulations may explain the risk of T2DM for generations. New data indicated that the placenta does not produce adiponectin and it is also one of the important factors for the development of gestational diabetes and risk for the fetus. Taken together all factors documented in the present paper may predict the risk for prenatal T2DM.
