Efecto de extractos de frutas y hortalizas en la incorporación de glucosa en células musculares in vitro

Rev. méd. Maule; 36 (2), 2021
Skeletal muscle appears to play a central role in the development of insulin resistance (IR) and consequently the metabolic syndrome due to high-fat diets, obesity, and aging. Recent evidence suggests that some bioactive compounds present in natural products can affect blood glucose, possibly due to inte...

Myostatin coordinating the proliferation and differentiation of adipose and skeletal muscle cells and energy metabolism balance based on gene chip technology

Rev. bras. med. esporte; 27 (spe2), 2021
ABSTRACT Myoblasts fuse into multinucleated muscle fibers to form and promote the growth of skeletal muscle. In order to analyze the role of myostatin (MSTN) in body fat, skeletal muscle cell proliferation and differentiation and energy metabolism, this study will use the antisense RNA technology of gene...

Smad1/5 signal transduction regulates the ameloblastic differentiation of induced pluripotent stem cells

Abstract Induced pluripotent stem (iPS) cells could be induced into ameloblast-like cells by ameloblasts serum-free conditioned medium (ASF-CM), and bone morphogenetic proteins (BMPs) might be essential during the regulation of this process. The present study investigates the signal transduction that reg...

Critical role of metabotropic glutamate receptor 4 in bone marrow-derived dendritic cells in the Th17 cell differentiation and the melanogenesis of B16 cells

Braz. j. med. biol. res; 53 (4), 2020
Vitiligo is an acquired pigmentary disorder resulting from selective destruction of melanocytes. Emerging studies have suggested that T helper cell 17 (Th17) is potentially implicated in vitiligo development and progression. It was recently discovered that metabotropic glutamate receptor 4 (mGluR4) can m...

Proliferation and differentiation of mouse spermatogonial stem cells on a three-dimensional surface composed of PCL/gel nanofibers

Int. j. morphol; 37 (3), 2019
Spermatogonial stem cells (SSCs) have self-renewal and differentiation capacity essential for sperm production throughout the male reproductive life. The electrospun polycaprolactone/gelatin (PCL/Gel) nanofibrous scaffold mimics important features of the extracellular matrix (ECM), which can provide a pr...

Biological modulation of corneal epithelial wound healing

Arq. bras. oftalmol; 82 (1), 2019
ABSTRACT The transparency and maintenance of corneal epithelial integrity are essential for its optical properties and, to preserve these characteristics, the epithelium undergoes continuous renewal. This renewal depends on the control of cell proliferation and differentiation mediated by mitogenic facto...

The E3 ligase MuRF2 plays a key role in the functional capacity of skeletal muscle fibroblasts

Braz. j. med. biol. res; 52 (9), 2019
Fibroblasts are a highly heterogeneous population of cells, being found in a large number of different tissues. These cells produce the extracellular matrix, which is essential to preserve structural integrity of connective tissues. Fibroblasts are frequently engaged in migration and remodeling, exerting...

Retinoic acid increases the effect of bone morphogenetic protein type 2 on osteogenic differentiation of human adipose-derived stem cells

J. appl. oral sci; 27 (), 2019
Abstract Bone morphogenetic protein type 2 (BMP-2) and retinoic acid (RA) are osteoinductive factors that stimulate endogenous mechanisms of bone repair which can be applied on management of osseous defects in oral and maxillofacial fields. Objective Considering the different results of RA on osteogene...

Induction of pluripotent stem cells by reprogramming human ocular fibroblasts under xeno-free conditions

Arq. bras. oftalmol; 81 (5), 2018
ABSTRACT Purposes: To develop an efficient and xeno-free standard eye-derived induced pluripotent stem cell reprogramming protocol for use during induced pluripotent stem cell-based cell therapies in treating retinal degenerative diseases and to compare the relative effectiveness of both animal- and non...
