The role of under-investigated connexins in musculoskeletal tissue: a brief review with emphasis on bone tissue

Actual. osteol; 13 (1), 2017
Connexins (Cxs) are a family of transmembrane proteins that form gap junctions and hemi-channels, which mediate cell-cell communication between neighboring cells and the respective extracellular milieu in different tissues. Most tissues and cell types throughout the body express one or more Cx proteins, ...

Osteoporosis and autophagy: What is the relationship?

Summary Autophagy is a survival pathway wherein non-functional proteins and organelles are degraded in lysosomes for recycling and energy production. Therefore, autophagy is fundamental for the maintenance of cell viability, acting as a quality control process that prevents the accumulation of unnecessar...

Expression regulation and functional analysis of RGS2 and RGS4 in adipogenic and osteogenic differentiation of human mesenchymal stem cells

Biol. Res; 50 (), 2017
BACKGROUND: Understanding the molecular basis underlying the formation of bone-forming osteocytes and lipid-storing adipocytes will help provide insights into the cause of disorders originating in stem/progenitor cells and develop therapeutic treatments for bone- or adipose-related diseases. In this stud...

β-ARRESTIN/CONNEXIN 43 (Cx43) complex anchors ERKS outside the nucleus: a prerequisite for bisphosphonate antiapoptotic effect mediated by Cx43/ERK in osteocytes

Actual. osteol; 12 (1), 2016
Bisphosphonates (BPs) anti-fracture efficacy may be due in part to inhibition of osteocyte apoptosis. This effect requires opening of connexin (Cx) 43 hemichannels and phosphorylation of the extracellular signal regulated kinases (ERKs). However, unlike ERK activation by other stimuli, the Cx43/ERK pathw...

Miniplates and mini-implants: bone remodeling as their biological foundation

Abstract The tridimensional network formed by osteocytes controls bone design by coordinating cell activity on trabecular and cortical bone surfaces, especially osteoblasts and clasts. Miniplates and mini-implants provide anchorage, allowing all other orthodontic and orthopedic components, albeit afar, t...

Aspectos celulares e moleculares da remodelação óssea
Cellular and molecular aspects of bone remodelation

Femina; 35 (5), 2007
O tecido ósseo é um tecido conjuntivo especializado e constituído por material extracelular calcificado (matriz óssea). Os ossos proporcionam proteção e suporte para o corpo e seus órgãos. Atuam como um importante reservatório, principalmente de íons cálcio e fosfato, além de servirem de apoi...

El mecanostato óseo
Mechanostat bone mass

Este trabajo presenta el mecanostato óseo a la mandíbula y al maxilar. Muestra que el efecto de las fuerzas deformantes, crecimiento óseo y la reabsorción ósea es el producto de la no deformación y el no trabajo. Se muestra también las células que participan en este proceso, su función y la apli...
