BACKGROUND/AIM: Colorectal cancer is frequently associated with metabolic diseases. Adiponectin (APN) is an insulin-sensitizing adipokine circulating as low molecular weight (LMW), medium molecular weight (MMW) and high molecular weight (HMW) oligomers; the latter are the most bio-active oligomers.

We analysed APN and HMW oligomers in sera, AdipoR1, AdipoR2 and T-cadherin expression in non-cancerous and cancerous colon tissues.

Abstract

BACKGROUND/AIM: Colorectal cancer is frequently associated with metabolic diseases. Adiponectin (APN) is an insulin-sensitizing adipokine circulating as low molecular weight (LMW), medium molecular weight (MMW) and high molecular weight (HMW) oligomers; the latter are the most bio-active oligomers. APN, through AdipoR1, AdipoR2 and T-cadherin receptors, regulates inflammation, and proliferation. Considering the anti-proliferative and anti-inflammatory properties of APN, we investigated the involvement of the "APN system" in colorectal cancer. MATERIALS AND METHODS: A total of 44 colorectal cancer patients and 51 healthy controls were recruited. We analysed APN and HMW oligomers in sera, AdipoR1, AdipoR2 and T-cadherin expression in non-cancerous and cancerous colon tissues. RESULTS: we found statistically lower levels of APN in patients compared to controls, with a specific decrease of HMW oligomers. Importantly, APN correlated to cancer grade. AdipoR1 was found overexpressed in cancerous compared to non-cancerous tissues while AdipoR2 and T-cadherin were down-regulated. CONCLUSION: The deregulated expression of the "APN system" in colorectal cancer with a specific correlation to tumor grade suggests APN as a promising biomarker in colorectal cancer.
