Obesity increases the risk of developing hypertension. Since both pathological entities constitute public health problems, the aim of this study was to investigate RNA expression of adiponectin, leptin and their receptors in adipose tissue in women with class 3 obesity, with or without hypertension. Serum concentrations of these adipokines were also quantitated. Women with obesity and hypertension (n = 22) and with obesity without hypertension (n = 37) were included. All patients presented class 3 obesity, without diabetes mellitus. The expression of mRNA in: adiponectin, ADIPOR1 and ADIPOR2 was analyzed in visceral (VAT) and subcutaneous (SAT) adipose tissue; leptin and its receptor were only analyzed in SAT, by reverse transcription quantitative PCR. Measurements of adiponectin and leptin concentrations were performed using enzyme-linked immunosorbent assay kits. Analysis of mRNA expressions in VAT and SAT are presented as median and quartiles. Analysis of serum concentrations of adipokines are presented as median and percentiles 25th–75th. Women presenting a higher mean arterial pressure, had significantly higher levels of mRNA expression of adiponectin in SAT. Besides, we found several significant positive correlations of these adipokines and their receptors. In conclusion, we found that those women with a higher mean arterial pressure and receiving antihypertensive treatment, presented higher levels of mRNA expression of adiponectin in SAT. •We analyzed adipokines in adipose tissue of women with obesity and hypertension.•We analyzed adipokines in adipose tissue of women with obesity without hypertension.•A higher mean arterial pressure, higher levels expression of adiponectin•Expression of adiponectin was lower in visceral than in subcutaneous adipose tissue.•The expression of LEP presented a positive correlation with expression of ADIPOR1.
