TRIM44 has oncogenic roles in various cancers. However, TRIM44 expression andits function in renal cell carcinoma (RCC) are still unknown. Here in this study, weinvestigated the clinical significance of TRIM44 and its biological function in RCC.TRIM44 overexpression was significantly associated with clinical M stage, histologictype (clear cell) and presence of lymphatic invasion (P = .047, P = .005, and P = .028,respectively). Moreover, TRIM44 overexpression was significantly associated withpoor prognosis in terms of cancer-specific survival (P = .019). Gain-of-function andloss-of-function studies using TRIM44 and siTRIM44 transfection showed thatTRIM44 promotes cell proliferation and cell migration in two RCC cell lines, Caki1and 769P. To further investigate the role of TRIM44 in RCC, we performed integratedmicroarray analysis in Caki1 and 769P cells and explored the data in the Oncominedatabase. Interestingly, FRK was identified as a promising candidate target gene ofTRIM44, which was downregulated in RCC compared with normal renal tissues. Wefound that cell proliferation was inhibited by TRIM44 knockdown and then recoveredby siFRK treatment. Taken together, the present study revealed the associationbetween high expression of TRIM44 and poor prognosis in

Renal cell carcinoma (RCC) is one of the common urologic neoplasms, and its incidence has been increasing over the past several decades; however, its pathogenesis is still unknown up to now. Recent studies have found that in addition to tumor cells, other cells in the tumor microenvironment also affect the biological behavior of the tumor. Among them, macrophages exist in a large amount in tumor microenvironment, and they are generally considered to play a key role in promoting tumorigenesis. Therefore, we summarized the recent researches on macrophage in the invasiveness and progression of RCC in latest years, and we also introduced and discussed many studies about macrophage in RCC to promote angiogenesis by changing tumor microenvironment and inhibit immune response in order to activate tumor progression. Moreover, macrophage interactes with various cytokines to promote tumor proliferation, invasion and metastasis, and it also promotes tumor stem cell formation and induces drug resistance in the progression of RCC. The highlight of this review is to make a summary of the roles of macrophage in the invasion and progression of RCC; at the same time to raise some potential and possible targets for future RCC therapy.

Abstract Background Metastatic spread to the pancreas is a rare event. Renal cell carcinoma represents one possible site of origin of pancreatic metastases. Renal cell carcinoma often metastasizes late and exclusively to the pancreas, suggesting a special role of renal cell carcinoma among primaries metastasizing to the pancreas. Even rarer, renal cell carcinoma may occur simultaneously with pancreatic ductal adenocarcinoma. Case presentation We present the case of a 78-year-old male Caucasian patient with a history of clear-cell renal cell carcinoma treated with oncological left nephrectomy 20 years before. The patient was diagnosed with pancreatic ductal adenocarcinoma by fine-needle aspiration cytology. At our institution, he received neoadjuvant therapy with folic acid, fluorouracil, irinotecan, oxaliplatin for borderline-resectable pancreatic ductal adenocarcinoma, and subsequently underwent total pancreatectomy. Upon resection, pancreatic ductal adenocarcinoma as well as two metachronous metastases of clear-cell renal cell carcinoma occurring simultaneously and cospatially with pancreatic ductal adenocarcinoma were diagnosed in the pancreatic body. Conclusions Renal cell carcinoma metastases of the pancreas are rare and often occur decades after the initial diagnosis of renal cell carcinoma. The combination of renal cell carcinoma metastases and pancreatic ductal adenocarcinoma is even rarer. However, the possibility should be considered by clinicians, radiologists, and pathologists. The special role of renal cell carcinoma as a site of origin of pancreatic metastasis should be further elucidated.
