Figure 4. Isoform-specific Nnat expression in the hypothalamus after surgery in relation to weight-loss and circulating leptin.

A–B) Nnat-α expression in the hypothalamus did not correlate with either change in body-weight or with circulating leptin after surgery; C–D) by contrast Nnat-β expression showed positive correlation with change in body-weight and weak positive correlation with circulating leptin after surgery; key – Nnat-α expression shown with open squares, Nnat-β with filled circles, AU = arbitrary units where Nnat expression was standardised using ubiquitin (Ubc) as a reference gene.
