The BRAFV600E mutation analysis and risk stratification in papillary thyroid carcinoma

ABSTRACT Objective: Although the prognostic role of BRAFV600E mutation in papillary thyroid carcinoma (PTC) is controversial, the American Thyroid Association (ATA) includes the mutational status in their risk stratification system. To evaluate the impact of the BRAFV600E mutation status on PTC risk str...

Prognostic value of long non-coding RNA TP73-AS1 expression in different types of cancer: a systematic review and meta-analysis

Background: TP73 antisense RNA 1 (TP73-AS1), a newly discovered long non-coding RNA (lncRNA), has been reported to be upregulated in various kinds of tumors, and shows a variable influence on living quality and prognosis of patients. Thus, we conducted a meta-analysis to evaluate the overall prognostic v...

MicroRNA-383-5p inhibits the progression of gastric carcinoma via targeting HDAC9 expression

Braz. j. med. biol. res; 52 (8), 2019
MicroRNAs (miRNAs), as post-transcriptional regulators, have been reported to be involved in the initiation and progression of various types of cancer, including gastric cancer (GC). The present study aimed to investigate the role of miR-383-5p in gastric carcinogenesis. Cell viability was analyzed using...

Identification of key genes involved in nasopharyngeal carcinoma

Abstract Introduction: Nasopharyngeal carcinoma is the most common cancer originating from the nasopharynx. Objective: To study the mechanisms of nasopharyngeal carcinoma, we analyzed GSE12452 microarray data. Methods: GSE12452 was downloaded from the Gene Expression Omnibus database and included 31 n...

Role of regenerating gene IA expression on local invasion and survival in nasopharyngeal carcinoma

Biol. Res; 50 (), 2017
BACKGROUND: Regenerating gene IA (REGIA) plays an important role in tissue regeneration and tumors prognosis of epithelium origin. However, the role of REGIA in nasopharyngeal carcinoma (NPC) is unclear. This study aims to investigate the expression and function of REG1A in NPC. RESULTS: We have found th...

Analysis of gene expression changes associated with human carcinoma-associated fibroblasts in non-small cell lung carcinoma

Biol. Res; 50 (), 2017
BACKGROUND: This study aimed to investigate the gene expression changes associated with carcinoma-associated fibroblasts (CAFs) involving in non-small cell lung carcinoma (NSCLC). METHODS: We downloaded the GEO series GSE22862, which contained matched gene expression values for 15 CAF and normal fibrobla...

Mutación V600E del oncogén BRAF en nódulos tiroideos en Argentina
BRAF V600E mutation in thyroid nodules in Argentina

Medicina (B.Aires); 76 (4), 2016
Este estudio prospectivo analizó en una población argentina la frecuencia de la mutación V600E del oncogén BRAF en pacientes operados por nódulos tiroideos benignos y por carcinoma papilar de tiroides. En estos últimos se compararon las características clínicas y anatomopatológicas en relación ...

Serological under expression of microRNA-21, microRNA-34a and microRNA-126 in colorectal cancer

Acta cir. bras; 31 (supl.1), 2016
PURPOSE: This paper describes the ability of miRNA value predict oncological outcomes in CRC patients and correlates to clinical and pathologic variables. METHODS: We prospectively analyzed the serological expression of microRNA-21, microRNA-34a, and microRNA-126 in 37 stage II - IV CRC patients and co...

Long non-coding RNA AFAP1-AS1 facilitates tumor growth and promotes metastasis in colorectal cancer

Biol. Res; 49 (), 2016
BACKGROUND AND OBJECTIVE: Long non-coding RNAs can regulate tumorigenesis of various cancers. Dys-regulation of lncRNA-AFAP1-AS1 has not been studied in colorectal carcinoma (CRC). This study was to examine the function involvement of AFAP1-AS1 in tumor growth and metastasis of CRC. METHODS: Relative exp...
