Up-regulation of GINS1 highlighted a good diagnostic and prognostic potential of survival in three different subtypes of human cancer

Braz. j. biol; 84 (), 2024
Abstract Cancer is a fatal malignancy and its increasing worldwide prevalence demands the discovery of more sensitive and reliable molecular biomarkers. To investigate the GINS1 expression level and its prognostic value in distinct human cancers using a series of multi-layered in silico approach may help...

El cáncer seguirá siendo uno de los mayores desafíos para la salud pública a nivel local y mundial. Actualmente, en nuestro país, el cáncer es la principal causa de muerte. Gracias al enorme conocimiento acumulado en las últimas décadas sobre las bases celulares y moleculares del cáncer, se ha d...

Diagnostic and prognostic significance of long noncoding RNA LINC00173 in patients with melanoma

SUMMARY OBJECTIVE: A growing volume of literature has suggested long noncoding RNAs (lncRNAs) as important players in tumor progression. In this study, we aimed to investigate the expression and prognostic value of lncRNA LINC00173 (LINC00173) in melanoma. METHODS: LINC00173 expression was measured in ...

Expressão do RNAm e metilação do DNA do gene DKK2 em câncer colorretal

Arq. gastroenterol; 58 (1), 2021
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...

Carcinoma del conducto salival: estudio clínico/patológico e inmunohistoquímico de 5 casos

El carcinoma del conducto salival es un tumor epitelial maligno agresivo, que involucra principalmente a la glándula parótida, con características histológicas semejantes al carcinoma ductal de glándula mamaria. El propósito de este trabajo fue presentar los resultados clínico-patológicos de cinc...

Association of kinesin family member 2A with increased disease risk, deteriorative clinical characteristics, and shorter survival profiles in acute myeloid leukemia

Braz. j. med. biol. res; 54 (2), 2021
This study aimed to explore the correlation of kinesin family member 2A (KIF2A) expression with disease risk, clinical characteristics, and prognosis of acute myeloid leukemia (AML), and investigate the effect of KIF2A knockdown on AML cell activities in vitro. Bone marrow samples were collected from 176...

Identification and clinical validation of gene signatures with grade and survival in head and neck carcinomas

Braz. j. med. biol. res; 54 (11), 2021
This study aimed to explore gene expression profiles that drive malignancy from low- to high-grade head and neck carcinomas (HNC), as well as to analyze their correlations with survival. Gene expressions and clinical data of HNC were downloaded from the Gene Expression Omnibus (GEO) repository. The signi...

Identification of 5-methylcytosine-related signature for predicting prognosis in ovarian cancer

Biol. Res; 54 (), 2021
BACKGROUND: Ovarian cancer is one of the most common malignancies often resulting in a poor prognosis. 5-methylcytosine (m5C) is a common epigenetic modification with roles in eukaryotes. However, the expression and function of m5C regulatory factors in ovarian cancer remained unclear. RESULTS: Two molec...

Low miR-1273a expression predicts poor prognosis of colon cancer and facilitates tumor cell proliferation, migration, and invasion

Braz. j. med. biol. res; 54 (2), 2021
MicroRNAs (miRNAs) have been indicated to be frequently dysregulated in various cancers and promising biomarkers for colon cancer. The present study aimed to assess the prognostic significance and biological function of miR-1273a in colon cancer. The expression levels of miR-1273a was estimated using qua...
