By a News Reporter-Staff News Editor at Cancer Weekly -- Current study results on Cancer have been published. According to news reporting from Shanghai, People's Republic of China, by NewsRx journalists, research stated, "Klotho is an anti-aging protein predominantly expressed in renal tubular epithelial cells. Although Klotho was recently identified as a tumor suppressor gene in a variety of cancers, the potential role and molecular events for Klotho in renal cell carcinoma (RCC) remain obscure."

The news correspondents obtained a quote from the research from Fudan University, "In the present study, immunohistochemical staining in tissue microarrays containing 125 RCC samples showed that intratumoral Klotho levels were negatively correlated with tumor size, TNM stage and nuclear grade. The overall survival rate of RCC patients with high Klotho expression was significantly higher than that of patients with low Klotho expression. Functional analysis after gain and loss of Klotho expression revealed that Klotho blunted epithelial-mesenchymal transition and cellular migration and invasion in RCC. Also, no alteration of a-2,6-sialidase activity was found after Klotho overexpression in RCC. The molecular signals for this phenomenon involved the Klotho-mediated inhibition of PI3K/Akt/GSK3??/Snail pathway. Importantly, compared to localized RCC tissues, advanced RCC tissues exhibited low Klotho expression accompanied with high pAkt and Snail expression. These results indicate Klotho acts as a tumor suppressor by inhibiting PI3K/Akt/GSK3??/Snail signaling, thus suppressing epithelial-mesenchymal transition and tumor migration and invasion during RCC progression."

According to the news reporters, the research concluded: "As a result, Klotho might be used as a potential therapy for advanced RCC."
