miR-660-5p promotes breast cancer progression through down-regulating TET2 and activating PI3K/AKT/mTOR signaling

Braz. j. med. biol. res; 53 (12), 2020
Breast cancer (BC) is a commonly diagnosed cancer in females. MicroRNA-660-5p (miR-660-5p) has been reported to be involved in the occurrence and development of BC. However, the regulatory network of miR-660-5p in BC has not been fully addressed. Quantitative real-time polymerase chain reaction (qRT-PCR)...

LINC00355 promoted the progression of lung squamous cell carcinoma through regulating the miR-466/LYAR axis

Braz. j. med. biol. res; 53 (12), 2020
LINC00355 has been reported aberrantly over-expressed and associated with poor prognosis in various types of cancer. However, reports regarding the effect of LINC00355 on lung squamous cell carcinoma (SCC) are rare. This study aimed to explore the function of LINC00355 in the development and progression ...

Human papillomavirus type 18 E5 oncoprotein cooperates with E6 and E7 in promoting cell viability and invasion and in modulating the cellular redox state

Mem. Inst. Oswaldo Cruz; 115 (), 2020
BACKGROUND High-risk human papillomaviruses (HR-HPVs) are the etiological agents of cervical cancer. Among them, types 16 and 18 are the most prevalent worldwide. The HPV genome encodes three oncoproteins (E5, E6, and E7) that possess a high transformation potential in culture cells when transduced simu...

Espectro fenotípico de Síndrome de CHARGE neonatal

Rev. chil. pediatr; 90 (5), 2019
INTRODUCCIÓN: El Síndrome de CHARGE (SCH), es un síndrome genético de amplia variabilidad fenotípica, de he rencia autosómica dominante, causado por variantes patogénicas en el gen CHD7. OBJETIVO: Descri bir el amplio espectro fenotípico de un SCH neonatal, heterocigoto para el gen CDH7 y la u...

Cepas chilenas de origen clínico de Vibrio cholerae no-O1, no-O139 portan los genes vcsN2, vcsC2, vcsV2, vspD, toxR2 y vopF del sistema de secreción T3SS2 presentes en una isla de patogenicidad

Rev. chil. infectol; 36 (3), 2019
Resumen Introducción. Los factores de virulencia de las cepas de Vibrio cholerae no-O1, no-O139 no son claramente conocidos. La cepa de origen septicémico NN1 Vibrio cholerae no-O1, no-O139 fue secuenciada previamente mediante la plataforma Illumina, detectándose en su genoma un fragmento de la isla ...

Immunoexpression of TS, p53, COX2, EGFR, MSH6 and MLH1 biomarkers and its correlation with degree of differentiation, tumor staging and prognostic factors in colorectal adenocarcinoma: a retrospective longitudinal study

Säo Paulo med. j; 137 (1), 2019
ABSTRACT BACKGROUND: There are cases of colorectal tumors that, although small, show more aggressive evolution than large tumors. This motivated us to study whether there are any proteins capable of alerting about these changes. The aim here was to correlate the immunoexpression of the TS, p53, COX2, E...

FSH receptor binding inhibitor up-regulates ARID1A and PTEN genes associated with ovarian cancers in mice

Braz. j. med. biol. res; 52 (7), 2019
Experiments were conducted to determine if the follicle-stimulating hormone (FSH) receptor binding inhibitor (FRBI) impacts the expression levels of AT-rich interactive domain-containing protein 1A (ARID1A) and phosphatase and tensin homolog (PTEN) in ovaries and blood, as well as expressions of follicle...

Identification of the targets of hematoporphyrin derivative in lung adenocarcinoma using integrated network analysis

Biol. Res; 52 (), 2019
BACKGROUND: Hematoporphyrin derivative (HPD) has a sensibilization effect in lung adenocarcinoma. This study was conducted to identify the target genes of HPD in lung adenocarcinoma. METHODS: RNA sequencing was performed using the lung adenocarcinoma cell line A549 after no treatment or treatment with X-...

Response to cytotoxic chemotherapy and overall survival in non-small cell lung cancer patients with positive or negative ERCC1 expression

J. bras. pneumol; 44 (3), 2018

Development and characterization of polyclonal antibodies against the linker region of the telomere-binding protein TRF2

Background: TRF2 (telomeric repeat binding factor 2) is an essential component of the telomere-binding protein complex shelterin. TRF2 induces the formation of a special structure of telomeric DNA and counteracts activation of DNA damage-response pathways telomeres. TRF2 has a poorly characterized linker...
