2. Fig. 1
a) Echocardiographic and hemodynamic parameters in normal (n=13), or 2-month CHF mice, either untreated (n=13) or chronically treated with the PTP1B inhibitor AS279 (n=15). * p<0.05 and ** p<0.01 vs. normal mice; † p<0.05 and †† p<0.01 vs. untreated CHF
b) Echocardiographic and hemodynamic parameters in normal or 2-month CHF mice, either WT (normal n=11, CHF n=12) or PTP1B−/− (normal n=11, CHF n=9)
* p<0.05 and ** p<0.01 vs. WT normal mice; † p<0.05 and †† p<0.01 vs. WT CHF mice.

3. Fig. 2
a) LV weight, LV weight/tibia length, infarct size and LV collagen density obtained normal (n=13) or CHF mice, either untreated (n=11) or chronically treated with the PTP1B inhibitor AS279 (n=15) (top)
b) LV weight, LV weight/tibia length, infarct size and LV collagen density obtained in WT (normal n=17, CHF n=15) or PTP1B−/− mice (normal n=20, CHF n=16). Representative images of collagen density in the four groups are also presented.
** p<0.01 vs. normal mice; † p<0.05 and †† p<0.01 vs. untreated or WT CHF mice.

4. Fig. 3
a) Effect of CHF and chronic pharmacological PTP1B inhibition on flow-mediated vasodilatation of mesenteric arteries (n=8–9 animals per group). Repeated measures ANOVA revealed statistically significant differences (p<0.01) between normal and CHF and between CHF and CHF+chronic PTP1B inhibition.
b) Effect of CHF and chronic pharmacological PTP1B inhibition on the vasodilatory responses of mesenteric arteries to acetylcholine or sodium nitroprusside (SNP) (n=8–9 animals per group).
c) Effect of in vitro incubation with the NOS inhibitor L-NNA and the PI3K inhibitor wortmannin of arteries isolated from CHF mice chronically treated with the PTP1B inhibitor AS279 (n=7 for L-NNA and 11 for wortmannin). Repeated measures ANOVA revealed statistically significant differences between base and L-NNA (p<0.01) and between base and wortmannin (p<0.05).
d) Representative Western blot data of total eNOS or P Ser1177-eNOS , and mean±SEM P Ser1177-eNOS/eNOS ratio and eNOS (n=6) in mesenteric arteries isolated from normal or CHF mice, either untreated or chronically treated with the PTP1B inhibitor AS279, and exposed to flow at 200μl/min for 2min. and 30sec.

5. Fig. 4
a) Flow-mediated vasodilatation of mesenteric arteries obtained from WT (n=16) or PTP1B−/− (n=8) normal mice (in the absence of CHF). Repeated measures ANOVA revealed statistically significant differences (p<0.01) between WT and PTP1B−/−.
b) Flow-mediated vasodilatation of mesenteric arteries obtained from WT (n=10) or PTP1B−/− mice (n=12) with CHF. Repeated measures ANOVA revealed statistically significant differences (p<0.01) between WT and PTP1B−/− CHF mice.
c) Effect of acute in vitro incubation with the PTP1B inhibitor AS179 on flow-mediated vasodilatation of mesenteric arteries isolated from PTP1B−/− CHF mice (n=7 ).
d) Representative PCR experiments showing PTP1B expression in the liver, lung, RV, LV, and small mesenteric artery (MA) from WT or PTP1B−/− normal mice.

a) Glucose turnover rate (ml/kg·min) assessed in euglycemic hyperinsulinemic clamp studies performed in normal mice (n=16), or CHF mice, either WT (n=9) or PTP1B−/− (n=17). * p<0.05 vs. CHF WT.
b) Vasodilatory responses to insulin of mesenteric arteries obtained from normal (n=6) or CHF mice, either WT (n=7) or PTP1B−/− (n=5). Repeated measures ANOVA revealed statistically significant differences between normal and CHF mice and between WT CHF and PTP1B−/− CHF mice.
