Biomarcadores en las neoplasias mieloproliferativas clásicas BCR-ABL1 negativas
Biomarkers in Classical Myeloproliferative Neoplasms BCR-ABL1 negative

Introducción: Los biomarcadores son útiles en la definición del diagnóstico, pronóstico y seguimiento de múltiples enfermedades. La detección o medición de uno o más biomarcadores específicos representan alteraciones en vías genéticas o epigenéticas que controlan la proliferación, diferenci...

Evolución de un linfoma no Hodgkin "triple expresor" en un paciente trasplantado renal con quimioterapia DA-R-EPOCH. Caso clínico

Rev. méd. Chile; 147 (2), 2019
Patients transplanted from solid organs have an increased risk of cancer, especially lymphomas. Lymphomas correspond to 4 to 5% of malignant neoplasms in the general population and in solid organ transplant patients it reaches an incidence of 21%. The incidence of non-Hodgkin lymphomas is 10 times higher...

Prevalence of ERG expression and PTEN loss in a Brazilian prostate cancer cohort

Braz. j. med. biol. res; 52 (12), 2019
PTEN is the most commonly inactivated tumor suppressor gene in primary prostate cancer (PCa) and its loss is associated with poor clinical outcomes. ERG rearrangement is a genomic alteration frequently found in PCa and its prognostic significance has yielded mixed results. Although the association of PTE...

Diagnostic utility of DREAM gene mRNA levels in thyroid tumours

ABSTRACT Objective The transcriptional repressor DREAM is involved in thyroid-specific gene expression, thyroid enlargement and nodular development, but its clinical utility is still uncertain. In this study we aimed to investigate whether DREAM mRNA levels differ in different thyroid tumors and how thi...

Decreased expression of chromodomain helicase DNA-binding protein 9 is a novel independent prognostic biomarker for colorectal cancer

Braz. j. med. biol. res; 51 (9), 2018
Previous studies suggested that chromodomain helicase DNA-binding proteins (CHDs), including CHD 1-8, were associated with several human diseases and cancers including lymphoma, liver cancer, colorectal cancer, stomach cancer, etc. To date, little research on CHD 9 in human cancers has been reported. In ...

Independent prognostic genes and mechanism investigation for colon cancer

Biol. Res; 51 (), 2018
PROPOSE: We aimed to explore the potential molecular mechanism and independent prognostic genes for colon cancer (CC). METHODS: Microarray datasets GSE17536 and GSE39582 were downloaded from Gene Expression Omnibus. Meanwhile, the whole CC-related dataset were downloaded from The Cancer Genome Atlas (TCG...

Caracterización de pacientes con cáncer colorrectal esporádico basado en la nueva subclasificación molecular de consenso

Rev. méd. Chile; 145 (4), 2017
Background: Colorectal cancer (CRC) is an heterogeneous disease. Three carcinogenic pathways determine its molecular profile: microsatellite instability (MSI), chromosomal instability (CIN) and CpG island methylator phenotype (CIMP). Based on the new molecular classification, four consensus CRC molecular...

Recomendaciones metodológicas para el monitoreo molecular BCR-ABL1 en pacientes con leucemia mieloide crónica por pcr cuantitativa en tiempo real
Guidelines for molecular monitoring of BCR-ABL1 in chronic myeloid leukemia patients by RT-qPCR

Medicina (B.Aires); 77 (1), 2017
Actualmente las guías clínicas para el manejo de pacientes con leucemia mieloide crónica incluyen el monitoreo molecular de BCR-ABL1 por PCR cuantitativa en tiempo real; esta metodología permite definir la respuesta molecular. A pesar de la probada importancia pronóstica de la respuesta molecular, e...

Alteración en la regulación de microRNAs en el cáncer gástrico: sobrerregulación de miR-21 y miR-106

El cáncer gástrico presenta una de las tasas de mortalidad más importante a nivel mundial, situación que es aún más preocupante en Colombia cuyas tasas son históricamente altas y en nuestro contexto regional particularmente para Boyacá, en la región nororiental de Colombia, es la primera causa d...

Minimal residual disease detection in Tunisian B-acute lymphoblastic leukemia based on immunoglobulin gene rearrangements

Braz. j. med. biol. res; 50 (1), 2017
IGH gene rearrangement and IGK-Kde gene deletion can be used as molecular markers for the assessment of B lineage acute lymphoblastic leukemia (B-ALL). Minimal residual disease detected based on those markers is currently the most reliable prognosis factor in B-ALL. The aim of this study was to use clona...
