Uma nova variante de splicing STK3/MST2 que exibe atividade de quinase reduzida e potencial clínico

A via Hippo consiste em uma cascata de serina-treonina quinases que desempenha um papel central na transdução de sinais mecânicos. Em mamíferos, o eixo canônico da via consiste na ativação das quinases MST1 e MST2 (codificadas pelos genes STK4 e STK3, respectivamente) e LATS1 e LATS2. A ativação...

Dopamina e comportamento alimentar: polimorfismos em receptores dopaminérgicos e fenótipos relacionados à obesidade

Clin. biomed. res; 41 (3), 2021
Dentre os sistemas neurais responsáveis pela ingestão dos alimentos, destaca-se a via dopaminérgica mesolímbica que, através da liberação de dopamina nos núcleos de accumbens, desperta prazer e motivação para recompensas químicas e naturais. Esta via de recompensa age através dos receptores d...

Long non-coding RNA DLGAP1-AS1 promotes the progression of gastric cancer via miR-515-5p/MARK4 axis

Braz. j. med. biol. res; 54 (8), 2021
Long non-coding RNA (lncRNA) is an essential regulator of carcinogenesis and cancer progression. In the study, we explored the role of lncRNA DLGAP1-AS1 in gastric cancer (GC). qRT-PCR was carried out to detect DLGAP1-AS1 expression in GC tissues and cell lines. CCK-8 assay, EdU assay, and transwell expe...

SAD-B modulates epileptic seizure by regulating AMPA receptors in patients with temporal lobe epilepsy and in the PTZ-induced epileptic model

Braz. j. med. biol. res; 53 (4), 2020
α-Amino-3-hydroxy-5-methyl-4-isoxazolepropionic acid (AMPA) receptors are the predominant mediators of glutamate-induced excitatory neurotransmission. It is widely accepted that AMPA receptors are critical for the generation and spread of epileptic seizure activity. Dysfunction of AMPA receptors as ...

Overexpression of CDC7 in malignant salivary gland tumors correlates with tumor differentiation

Abstract Introduction: Cell division cycle-7 protein is a serine/threonine kinase that has a basic role in cell cycle regulation and is a potential prognostic or therapeutic target in some human cancers. Objectives: This study investigated the expression of cell division cycle-7 protein in benign and m...

Psoralen inhibits malignant proliferation and induces apoptosis through triggering endoplasmic reticulum stress in human SMMC7721 hepatoma cells

Biol. Res; 52 (), 2019
BACKGROUND: Psoralen is a coumarin-like and coumarin-related benzofuran glycoside, which is a commonly used traditional Chinese medicine to treat patients with kidney and spleen-yang deficiency symptom. Psoralen has been reported to show estrogen-like activity, antioxidant activity, osteoblastic prolifer...

Linderae radix ethanol extract attenuates alcoholic liver injury via attenuating inflammation and regulating gut microbiota in rats

Braz. j. med. biol. res; 52 (6), 2019
This study aimed to explore the influence of gut microbiota alterations induced by Linderae radix ethanol extract (LREE) on alcoholic liver disease (ALD) in rats and to study the anti-inflammatory effect of LREE on ALD through the lipopolysaccharide (LPS) toll-like receptor 4 (TLR4)-nuclear factor kappa ...

CMPD1 inhibited human gastric cancer cell proliferation by inducing apoptosis and G2/M cell cycle arrest

Biol. Res; 51 (), 2018
BACKGROUND: Gastric cancer occupies the fourth highest morbidity rate of cancers worldwide. Clinical therapies of gastric cancer remain limited because of uncertainty of mechanisms and shortness of effective medicine. Thus, new drug candidates for gastric cancer treatment is urgently needed. RESULTS: In ...

Prevalence of polymorphisms in the ANKK1, DRD2, DRD3 genes and metabolic syndrome in refractory schizophrenia

ABSTRACT Objective: to estimate the prevalence of TaqIA, -141C and rs6280 polymorphisms of the ANKK1, DRD2 and DRD3 genes and evaluate their association with the occurrence of metabolic syndrome in patients with refractory schizophrenia. Method: cross-sectional study conducted in the Extended Western R...

More than kin, less than kind: one family and the many faces of diabetes in youth

SUMMARY Identification of the correct etiology of diabetes brings important implications for clinical management. In this report, we describe a case of a 4-year old asymptomatic girl with diabetes since age 2, along with several individuals in her family with different etiologies for hyperglycemia identi...
