Lean heart: Role of leptin in cardiac hypertrophy and metabolism

Figure 1 Comparison of leptin receptor isoforms in the mouse brain and heart. RNA was isolated from the brain and heart and reverse transcribed into cDNA. Polymerase chain reaction was then performed using primers specific for each mouse isoform of the leptin receptor as previously described[12]. All 5 of the leptin receptor isoforms were detected in the mouse heart as well as the brain.
