Determining the role of BRCA1 in skeletal muscle regeneration

open access: yes, 2023
Skeletal muscle is necessary for movement, breathing, and performance of daily activities. Acute injuries can occur to skeletal muscle, and there are several conditions and diseases that result in impairment of muscle repair (muscular dystrophies ...

Comparative cranial biomechanics reveal macroevolutionary trends in theropod dinosaurs, with emphasis on Tyrannosauroidea

open access: yesThe Anatomical Record, EarlyView.
Abstract Tyrannosaurus is viewed as a model organism in vertebrate paleontology, with numerous studies analyzing its feeding biomechanics. Nonetheless, the evolution of this feeding performance has been under‐addressed in Tyrannosauroidea, especially in basal tyrannosauroids. Here we used muscle‐force reconstruction and finite element analysis (FEA) to

MicroCT reinvestigation of the only articulated fossil anostomid fish reveals synonymy of Arhinolemur Ameghino, 1898 and Megaleporinus Ramirez et al., 2017

open access: yesThe Anatomical Record, EarlyView.
Abstract Arhinolemur scalabrinii† Ameghino, 1898 was originally described as a strepsirrhine primate (Mammalia) but has been recognized as an anostomid fish since 2012. It remains the only extinct anostomid species known from complete cranial material.

Morpho‐functional analyses of the jaw apparatus in the Blue‐and‐yellow Macaw (Ara ararauna, Psittaciformes, Aves): Adaptations to feeding behavior

open access: yesThe Anatomical Record, EarlyView.
Abstract Macaws are renowned for processing dry, mechanically resistant fruits, yet the species‐level anatomical and functional correlates of this performance remain incompletely resolved. We examined the feeding apparatus of the Blue‐and‐yellow Macaw (Ara ararauna) using an integrated approach that combines osteology, myology, and bite‐force estimates

Dynamics and epigenetic control of PcG proteins during skeletal muscle cell differentiation

open access: yes, 2010
During skeletal muscle differentiation, signal dependent switches in cell differentiation programs require global rearrangements in repression and activation of lineage specific genes, hence the importance of unravelling epigenetic mechanisms that ...

Cardiac morphological and morphometric analysis of Ardea alba

open access: yesThe Anatomical Record, EarlyView.
Abstract Ardea alba (Linnaeus, 1758) is a widely distributed heron species whose cardiovascular morphology remains poorly described. This study aimed to characterize the cardiac morphology and morphometry of adult A. alba. Ten specimens were analyzed using radiographic, morphometric, histological, scanning electron microscopy, and three‐dimensional ...

Satellite Cell Proliferative Compartments in Growing Skeletal Muscles

open access: yesDevelopmental Biology, 1996
The cell cycle time of satellite cells in growing rats was determined to be approximately 32 hr, with an S-phase of 14 hr. The estimated cycle time was the same for satellite cells in both oxidative soleus and glycolytic EDL muscles and is consistent with the rate at which myonuclei are produced during growth.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

open access: yesAnimal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Investigating the Role of Type I Interferon Signaling on Muscle Disease Using Mouse Models

open access: yesArthritis &Rheumatology, EarlyView.
Objective Dysregulated type I interferon (IFN) signaling contributes to autoimmune myositis pathogenesis. We investigated the therapeutic effects of JAK inhibitors in two mouse models. We also examined how type I IFNs affect muscle vasculature. Methods Myositis was induced in major histocompatibility complex class I double transgenic ([TRE‐H‐2Kb (H ...

The characterisation and role of mighty during myogenesis

open access: yes, 2006
Myogenesis, or skeletal muscle formation, begins during embryogenesis and involves the proliferation of myoblasts followed by their exit from the cell-cycle to differentiate and form myotubes.
