FAMLF is a target of miR-181b in Burkitt lymphoma

Braz. j. med. biol. res; 50 (6), 2017
Burkitt lymphoma (BL) is a highly malignant non-Hodgkin's lymphoma that is closely related to the abnormal expression of genes. Familial acute myelogenous leukemia related factor (FAMLF; GenBank accession No. EF413001.1) is a novel gene that was cloned by our research group, and miR-181b is located in th...

MicroRNA-98 inhibits the cell proliferation of human hypertrophic scar fibroblasts via targeting Col1A1

Biol. Res; 50 (), 2017
BACKGROUND: Hypertrophic scarring (HS) is a severe disease, and results from unusual wound healing. Col1A1 could promote the hypertrophic scar formation, and the expression of Col1A1 in HS tissue was markedly higher than that in the normal. In present study, we aimed to identify miRNAs as post-transcript...

miR-22 suppresses tumorigenesis and improves radiosensitivity of breast cancer cells by targeting Sirt1

Biol. Res; 50 (), 2017
BACKGROUND: miR-22 has been shown to be frequently downregulated and act as a tumor suppressor in multiple cancers including breast cancers. However, the role of miR-22 in regulating the radioresistance of breast cancer cells, as well as its underlying mechanism is still not well understood. METHODS: The...

Lipídios estruturados obtidos por interesterificação da tributirina com óleo de linhaça e seu potencial quimiopreventivo durante a fase de promoção inicial da hepatocarcinogênese experimental em ratos

A combinação de agentes quimiopreventivos com diferentes mecanismos de ação tem sido considerada uma estratégia promissora para a prevenção do câncer. Dentre os diversos compostos bioativos em alimentos, destacam-se a tributirina, um pró-fármaco do ácido butírico presente em laticínios e pro...

Cadmium-induced apoptosis of Siberian tiger fibroblasts via disrupted intracellular homeostasis

Biol. Res; 49 (), 2016
BACKGROUND: Heavy metals can cause great harm to Siberian tigers in the natural environment. Cadmium (Cd2+) is an environmental contaminant that affects multiple cellular processes, including cell proliferation, differentiation, and survival. It has been shown to induce apoptosis in a variety of cell typ...

microRNAs y diabetes tipo 1

The worldwide increased incidence of type 1 diabetes (T1D) and the decreased genotypes that confer increased risk to T1D indicate a strong environmental impact on the disease. These mechanisms could occur through epigenetic modifications that operate on several gene expression patterns (methylation and a...

INXS, um longo RNA não codificador de proteínas mediador da apoptose

O splicing alternativo do pré-mRNA de BCL-X produz duas isoformas de mRNAs com funções antagônicas, a pró-apoptótica BCL-XS e a anti-apoptótica BCL-XL, cujo balanço regula a homeostasia celular. Entretanto, o mecanismo que regula esse processamento ainda é desconhecido. Nesse trabalho, nós iden...

Expression of TRF2 and its prognostic relevance in advanced stage cervical cancer patients

Biol. Res; 47 (), 2014
BACKGROUND: Telomeres are protective caps consisted of specific tandem repeats (5'-TTAGGG-3'). Shortening of telomeres at each cell division is known as "mitotic clock" of the cells, which renders telomeres as important regulators of lifespan. TRF2 is one of the critical members of shelterin complex, whi...

Simultaneous silencing of VEGF and KSP by siRNA cocktail inhibits proliferation and induces apoptosis of hepatocellular carcinoma Hep3B cells

Biol. Res; 47 (), 2014
BACKGROUND: Vascular endothelial growth factor (VEGF) is involved in the growth of new blood vessels that feed tumors and kinesin spindle protein (KSP) plays a critical role in mitosis involving in cell proliferation. Simultaneous silencing of VEGF and KSP, an attractive and viable approach in cancer, le...

Mecanismos moleculares envolvidos em citoproteção e transformação maligna de células-beta pancreáticas

O transplante de ilhotas pancreáticas constitui uma alternativa atraente para o tratamento de diabetes tipo 1 (DM1), contudo, é limitado devido à escassez de doadores de órgãos. O papel da prolactina humana recombinante (rhPRL), que apresenta efeitos benéficos em células-beta, e seu mecanismo de a...
