Expression of CHPF modulates cell proliferation and invasion in lung cancer

Braz. j. med. biol. res; 53 (5), 2020
Lung cancer is the most common malignancy worldwide and is characterized by rapid progression, aggressive behavior, frequent recurrence, and poor prognosis. The TCGA database indicates that chondroitin polymerizing factor (CHPF) is overexpressed in human lung cancer tissues compared with normal tissues a...

MicroRNA-4290 suppresses PDK1-mediated glycolysis to enhance the sensitivity of gastric cancer cell to cisplatin

Braz. j. med. biol. res; 53 (5), 2020
The development of chemotherapy resistance significantly impairs the efficiency of chemotherapy, but the underlying mechanisms of chemotherapy resistance in gastric cancer (GC) are complicated and still need to be further explored. Here, we aimed to reveal the effects of miR-4290/PDK1 (pyruvate dehydroge...

MALAT1 is involved in type I IFNs-mediated systemic lupus erythematosus by up-regulating OAS2, OAS3, and OASL

Braz. j. med. biol. res; 53 (5), 2020
Systemic lupus erythematosus (SLE) is an autoimmune disease associated with an aberrant activation of immune cells partly due to the dysfunction of cytokines such as type I interferons (IFNs). Long non-coding RNA MALAT1 has been found to play a pathogenic role in SLE; however, the underlying mechanisms a...

miR-378a-5p and miR-630 induce lens epithelial cell apoptosis in cataract via suppression of E2F3

Braz. j. med. biol. res; 53 (5), 2020
Cataract, an eye disease that threatens the health of millions of people, brings about severe economic burden for patients and society. MicroRNA (miR)-378a-5p and miR-630 were recognized as essential regulators in multiple cancers. However, the exact functions of miR-378a-5p and miR-630 in cataract are s...

LncRNA SNHG7/miR-34a-5p/SYVN1 axis plays a vital role in proliferation, apoptosis and autophagy in osteoarthritis

Biol. Res; 53 (), 2020
BACKGROUND: Osteoarthritis (OA) is one of the most common rheumatic diseases of which clinical symptoms includes swelling, synovitis and inflammatory pain, affect patients' daily life. It was reported that non-coding RNAs play vital roles in OA. However, the regulation mechanism of ncRNA in OA pathogenes...

Preliminary findings on the possible role of B-lymphocyte stimulator (BLyS) on diabetes-related periodontitis

Abstract The possible role of B-cell growth and differentiation-related cytokines on the pathogenesis of diabetes-related periodontitis has not been addressed so far. The aim of this study was to evaluate the effects of diabetes mellitus (DM) on the gene expression of proliferation-inducing ligand (APRIL...

Effect of focal adhesion kinase inhibition on osteoblastic cells grown on titanium with different topographies

J. appl. oral sci; 28 (), 2020
Abstract Objective The present study aimed to investigate the participation of focal adhesion kinases (FAK) in interactions between osteoblastic cells and titanium (Ti) surfaces with three different topographies, namely, untreated (US), microstructured (MS), and nanostructured (NS). Methodology Osteo...

The effect of Maras powder and smoking on the microRNA deregulation of oral mucosa

J. appl. oral sci; 28 (), 2020
Abstract Objective This study aimed to investigate the effects of Maras powder (a type of smokeless tobacco obtained from Nicotiana rustica Linn and mixed with the ashes of wood, especially from oak, walnut or grapevine) on the microRNA (miRNA) deregulation of oral mucosa, and it compares these effects...

Autochthonous canine visceral leishmaniasis cases occur in Paraná state since 2012: isolation and identification of Leishmania infantum

Abstract The aim of this study was to confirm the emergence of canine visceral leishmaniasis among dogs in Foz do Iguaçu. The disease was diagnosed through the isolation and molecular identification of Leishmania infantum. In the first sample collection stage (2012), three lymph node aspirates and 46 bu...

The neurogenic effects of rosmarinic acid in a mouse model of type 2 diabetes mellitus

There is emerging evidence for a dysregulation of insulin signaling in the brains of patients with Alzheimer's disease (AD) with overlapping molecular features to Type 2 Diabetes Mellitus (T2DM). In addition, T2DM is a known risk factor of AD. The goal of this study was to investigate the neurogenic and ...
