Objective:
The aim of this study was to analyze lamin A/C mRNA levels in abdominal subcutaneous adipose tissue in two conditions-obesity and type 2 diabetes-that share common inflammatory and metabolic features, and to assess their relationship with selected inflammatory and adipogenic genes.
Methods And Procedures:
This is a cross-sectional study involving 52 nondiabetic and 54 type 2 diabetes patients. Anthropometrical and analytical measurements (glycemic, lipidic, and inflammatory profiles) were performed, and mRNA expression was determined using real-time PCR.
Results:
Lamin A and C isoforms are expressed differentially. Lamin A/C mRNA levels were increased in obese and in type 2 diabetes patients. We also observed a strong relationship between both isoforms (B = 2.218, P < 0.001) and among lamin C mRNA expression and adipogenic (sterol-responsive element binding protein-1 (SREBP1c)) and inflammatory (interleukin-6 (IL-6)) markers (B = 0.854, P = 0.001, and B = 0.557, P < 0.001, respectively).
Discussion:
These data suggest that lamin A/C may be involved in the adipocyte gene profile observed in obesity and type 2 diabetes.

Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in the...
