Renal cell carcinoma (RCC) is a common fatal malignancy that accounts for more than 2% of all adult cancers, and 80% of renal cell carcinomas are subdivided into clear cell renal cell carcinoma (ccRCC) based on histological and cytogenetic characteristics. Perirenal adipose tissue (PAT) is a type of white adipose tissue (WAT) located between the renal fascia and the renal capsule. During tumorigenesis, ccRCC cells can penetrate the renal capsule and enter the PAT, which is associated with poor prognosis of renal cancer. However, the interaction between ccRCC and PAT has not been well investigated. Through in-depth exploration of the two-way communication between ccRCC cells and PAT, the researchers found that ccRCC cells secrete parathyroid hormone-related protein (PTHrP) through paracrine mode to activate the PKA pathway to drive the browning of adjacent PAT, which enhances the metabolism of brown perirenal adipocytes and releases a large number of metabolites, in which excess lactic acid is released into the tumor microenvironment, thus promoting the growth, invasion and metastasis of ccRCC, constituting a new possible mechanism to promote the growth of ccRCC tumors. This study suggests that removal of adjacent adipose tissue during kidney cancer surgery may prevent the flow of metabolites of brown adipocytes, thus improving the prognosis after surgery.
