miR-139-5p protects septic mice with acute lung injury by inhibiting Toll-like receptor 4/Myeloid differentiation factor 88/Nuclear factor-&mac_kgr; B signaling pathway

Clinics; 76 (), 2021
OBJECTIVES: To investigate the role of miR-139-5p and the TLR4/MyD88/NF-κB signaling pathway in acute lung injury in septic mice. METHOD: A total of 140 healthy male SPF C57BL/6 mice were divided into seven groups, i.e., Normal, Control, NC, miR-139-5p mimic, miR-139-5p inhibitor, TAK-242, and miR-...

Study of muscle fibers of the extensor digitorium longus and soleus muscles of C57BL/6 females exposed to glyphosate during pregnancy and lactation

ABSTRACT Objective To evaluate the morphology and morphometry of the muscles extensor digitorium longus and soleus of C57BL/6 females, who were exposed to glyphosate during pregnancy and lactation. Methods Twelve female mice from the C57BL/6 lineage were used. After detection of pregnancy, they were ...

Exo70 intracellular redistribution after repeated mild traumatic brain injury

Biol. Res; 54 (), 2021
BACKGROUND: Exo70 is a subunit of the greater exocyst complex, a collection of proteins that oversees cellular membrane addition and polarized exocytosis by acting as a tethering intermediate between the plasma membrane and newly synthesized secretory vesicles. Although Exo70 function has been implicated...

Structural and functional alterations in heart and skeletal muscle following severe TAC in mice: impact of moderate exercise training

Biol. Res; 54 (), 2021
BACKGROUND: Heart failure (HF) is the leading cause of death in western countries. Cardiac dysfunction is accompanied by skeletal alterations resulting in muscle weakness and fatigue. Exercise is an accepted interventional approach correcting cardiac and skeletal dysfunction, thereby improving mortality,...

Spatio-temporal expression profile of Mettl3/Mettl14 during mouse retina development

Int. j. morphol; 38 (6), 2020
SUMMARY: The Mettl3/Mettl14 methyltransferase complex installs the most ubiquitous internal mRNA modification- N6-methyladenosine (m6A). The vertebrate retina development is a multi-step process that requires fine-tuning of multiple cellular events, but very little is known about the potential function o...

Protective effect of CD73 inhibitor α, β-methylene ADP against amyloid-β-induced cognitive impairment by inhibiting adenosine production in hippocampus

BACKGROUND: Alzheimer's disease (AD) is a chronic, progressive neurodegenerative disease. Recent studies have reported the close association between cognitive function in AD and purinergic receptors in the central nervous system. In the current study, we investigated the effect of CD73 inhibitor α, β-m...

Role of FAK signaling in chagasic cardiac hypertrophy

Braz. j. infect. dis; 24 (5), 2020
Abstract Cardiac hypertrophy and dysfunction are a significant complication of chronic Chagas disease, with heart failure, stroke, and sudden death related to disease progression. Thus, understanding the signaling pathways involved in the chagasic cardiac hypertrophy may provide potential targets for pha...

Características morfocuantitativas de la glándula submandibular de ratón (Mus musculus)

Int. j. morphol; 38 (3), 2020
El ratón (Mus musculus) es un buen modelo animal de experimentación, donde sus glándulas salivales han sido utilizadas en estudios, especialmente de tipo preclínico. Sin embargo, las diferencias en la morfología de estas glándulas y, en particular de las submandibulares, entre humanos y roedores no...

Enhancement of cellular activity in hyperglycemic mice dermal wounds dressed with chitosan-alginate membranes

Braz. j. med. biol. res; 53 (1), 2020
The use of specially designed wound dressings could be an important alternative to facilitate the healing process of wounds in the hyperglycemic state. Biocompatible dressings combining chitosan and alginate can speed up wound healing by modulating the inflammatory phase, stimulating fibroblast prolifera...

CCR3 antagonist impairs estradiol-induced eosinophil migration to the uterus in ovariectomized mice

Braz. j. med. biol. res; 53 (1), 2020
Eosinophils are abundant in the reproductive tract, contributing to the remodeling and successful implantation of the embryo. However, the mechanisms by which eosinophils migrate into the uterus and their relationship to edema are still not entirely clear, since there are a variety of chemotactic factors...
