Background Peripheral artery disease (PAD) of the lower limbs is a common condition that can affect quality of life. Androgen receptor (AR) can exert sex-specific effects on metabolic system, endothelial function and vascular tone. IGF-I receptor (IGF-IR) and insulin receptor (IR) may also be involved in the aforementioned functions. The aim of this study was to evaluate AR, IGF-IR and IR expression in the arterial vessel walls of PAD patients. Results: This is a cross-sectional study examining 30 males with PAD undergoing open surgery procedures. Mean age was 75.9±8.8y. All patients belonged to Rutherford stage 4-6. Median expression levels of IR, IGF-IR and AR significantly decreased from stage 4 to 6 (p < 0.05). Significance: the study evidenced a progressive decrease of IR, IGF-IR and AR expression as the severity of disease increased. Altered levels of IR, IGF-IR and AR following PAD may be useful for the clinical evaluation of these patients.

Abstract
Background Peripheral artery disease (PAD) of the lower limbs is a common condition that can affect quality of life. Androgen receptor (AR) can exert sex-specific effects on metabolic system, endothelial function and vascular tone. IGF-I receptor (IGF-IR) and insulin receptor (IR) may also be involved in the aforementioned functions. The aim of this study was to evaluate AR, IGF-IR and IR expression in the arterial vessel walls of PAD patients. Results: This is a cross-sectional study examining 30 males with PAD undergoing open surgery procedures. Mean age was 75.9±8.8y. All patients belonged to Rutherford stage 4-6. Median expression levels of IR, IGF-IR and AR significantly decreased from stage 4 to 6 (p < 0.05). Significance: the study evidenced a progressive decrease of IR, IGF-IR and AR expression as the severity of disease increased. Altered levels of IR, IGF-IR and AR following PAD may be useful for the clinical evaluation of these patients.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
