Matrix metallopeptidase 9 (MMP9) was found to be associated with tumor aggressiveness. In this study, we focused on the correlation between MMP9 expression and clear cell renal carcinoma (ccRCC). Through the Gene Expression Omnibus (GEO) database, the Cancer Genome Atlas (TCGA) database and immunohistochemical (IHC) staining, we observed that compared with adjacent normal renal tissues, in ccRCC tissues the mRNA and protein levels of MMP9 were enhanced, and the mRNA levels of GTP-binding protein smg p21B(RAP1B), B rapidly accelerated fibrosarcoma (RAF), methyl ethyl ketone2 (MEK2), extracellular regulated protein kinases1 (ERK1), ERK2, v-ets avian erythroblastosis virus E26 oncogene homolog1 (ETS1) and ETS2 also increased. The Kaplan–Meier survival analysis suggested that high MMP9 expression was an unfavorable prognostic biomarker for ccRCC patients. Our results indicated that the increased expression level of MMP9 in ccRCC may be due to the activation of the Mitogen-activated protein kinases (MAPK)/ERK signaling pathway, and MMP9 may be an attractive target for ccRCC therapy.

ABSTRACT:Introduction: The first reports of renal tumors originated from the renal tubule epithelium date from 1855, Robin, and 1867, Waldeyer. However, at the same era, some pathologists wrong believed these tumors were originated from adrenal gland tissues due to the fat content of the tumor (hypernephroid tumor theory - origin above the kidney, 1894). The first diagnostic test for renal tumor was excretory urography. Over the years, with the emergence of ultrasonography (US), it has been replaced. Nowadays, after the US screening, all renal lesions should be evaluated, in a complementary way, with computed tomography (CT) - gold standard - in the pre-contrast, arterial, portal, nephrographic phases. This is necessary to characterize the presence of enhancement after contrast. A kidney injury that enhances more than 15 Housfield units (UH) is suspected of kidney cell cancer. There are different subtypes of renal tumors derived from various sites of the nephron. Clear cell Renal Cell Carcinoma (RCC) is one of the subtypes that originates from the renal cortex. It is a rare tumor in children. Objective: The aim of this chapter is to review de incidence, pathology, diagnosis and treatment in clear-cell renal carcinoma in pediatric population. Methods: The authors performed a literary review about clear-cell renal carcinoma in pediatric population using Pubmed Database and Campbell-Walsh Urology as source search.Keywords: Renal cell carcinoma, Tumor, Pediatrics, Kidney, Nefrectomy ResumoRESUMO:Introdução: Os primeiros relatos de tumores renais originados do epitélio do túbulo renal datam de 1855, Robin, e 1867, Waldeyer. Contudo, na mesma época, alguns patologistas acreditavam erroneamente que esses tumores provinham dos tecidos das glândulas supra-renais, devido ao teor de gordura do tumor (hypernephroid tumor theory – origem acima do rim, 1894). O primeiro teste diagnóstico para tumor renal foi a urografia excretora. Ao longo dos anos, com o surgimento da ultrassonografia, esse teste foi substituído. Atualmente, após a leitura da ultrassonografia, todas as lesões renais devem ser avaliadas, de forma complementar, com tomografia computadorizada (TC) – padrão ouro – nas fases pré-contraste, arterial, porta e nefrográfica. Isso é necessário para caracterizar a presença de melhora após contraste. Uma lesão renal que aumenta mais de 15 unidades Housfield (UH) é suspeita de câncer de células renais. Existem diferentes subtipos de tumores derivados de vários locais do néfron. O carcinoma de células renais de células claras (CCR) é um dos subtipos originários do córtex renal. É um tumor raro em crianças. Objetivo: O objetivo deste capítulo é revisar a incidência, a patologia, o diagnóstico e o tratamento do CCR na população pediátrica. Método: Os autores realizaram uma revisão literária sobre carcinoma renal de células claras em população pediátrica usando a base de dados PubMed e o livro Campbell-Walsh de Urologia como fonte de pesquisa.Palavras chave: Carcinoma de células renais, Tumor, Pediatria, Rim, Nefrectomia
