Introducción. El cáncer colorrectal tiene una alta incidencia en la población mundial. Diversas vías moleculares están involucradas en su desarrollo, entre ellas, la inestabilidad cromosómica, la inestabilidad microsatelital y la epigenética. Objetivo. Hacer la caracterización molecular de 44 ind...
Si bien el carcinoma colorrectal (CCR) es la tercera enfermedad oncológica más frecuente en adultos, solo el 1-4 % ocurre en menores de 25-30 años. Su presentación suele confundirse con otras patologías, lo cual lleva a significativas demoras diagnósticas. Dada su baja incidencia, pocos pediatra...
ABSTRACT BACKGROUND: Colorectal cancer is the third most common neoplasm in the world. Methylation of tumor related genes in CpG islands can cause gene silencing and been involved in the development of cancer. The potential role of DKK2 as a biomarker for early diagnosis of colorectal cancer remains un...
SUMMARY OBJECTIVE: Colorectal cancer is the most common malignancy of the gastrointestinal tract. It is the third most common tumor in both genders and the second reason of cancer-related deaths. In recent years, tumor location has gained importance as a prognostic indicator. In this study, we aimed to ...
ABSTRACT Background: Inhibitors of the epidermal growth factor (EGFR) represent an effective therapeutic option for patients with metastatic colorectal carcinoma, free of activating mutations in KRAS and NRAS. However, the research of mutations is of high cost and scarcely accessible. The expression of ...
RESUMO - INTRODUÇÃO: O papilomavírus humano (HPV) é agente das doenças sexualmente transmissíveis de maior prevalência no mundo que estão associadas ao câncer do colo do útero e canal anal. A ação do HPV na carcinogênese colorretal não está ainda estabelecida. OBJETIVO: Estudar a eventua...
Recently, an increasing number of studies have reported that dysregulation of circular RNA (circRNA) expression plays critical roles in the progression of several cancers, including colorectal cancer (CRC). However, the detailed molecular mechanisms of circRNAs involvement in CRC remain largely unknown. ...
SUMMARY OBJECTIVE: Long noncoding RNAs (lncRNAs) have been proven to exhibit distinct functions on the convoluted processes of tumor developments. Some studies on the biological functions of lncRNA MAFG-AS1 (MAFG-AS1) in cancers revealed that they may serve as an oncogene in some kinds of tumors, includ...
Colorectal (CRC) is one of the most common types of cancer worldwide. Most tumors develop from an adenoma in a period of 10 to 15 years, but some may appear without previous adenomatous lesions. Seventy-five percent of colorectal cancers are sporadic, 20% have a family component (first or second-degree r...
