BACKGROUND: Myostatin is a protein synthesized and secreted by skeletal muscle that negatively regulates muscle mass. The extent to which circulating myostatin levels change in the context of aging is controversial, largely due to methodological barriers.METHODS: We developed a...

PMID: 25878769
Skelet Muscle. 2015 Mar 18;5:8. doi: 10.1186/s13395-015-0032-z. eCollection 2015.

BACKGROUND: The effects of transforming growth factor-beta (TGFβ) are mediated by the transcription factors Smad2 and Smad3. During adult skeletal myogenesis, TGFβ signaling inhibits the differentiation of myoblasts, and this can be reversed by treatment with retinoic acid (RA)....

Myostatin blockade with a fully human monoclonal antibody induces muscle hypertrophy and reverses muscle atrophy in young and aged mice.

Skeletal muscle

Latres E, Pangilinan J, Miloscio L, Bauerlein R, Na E, Potocky TB, Huang Y, Eckersdorff M, Rafique A, Mastaitis J, Lin C, Murphy AJ, Yancopoulos GD, Gromada J, Stitt T.
PMID: 26457176
Skelet Muscle. 2015 Oct 09;5:34. doi: 10.1186/s13395-015-0060-8. eCollection 2015.

BACKGROUND: Loss of skeletal muscle mass and function in humans is associated with significant morbidity and mortality. The role of myostatin as a key negative regulator of skeletal muscle mass and function has supported the concept that inactivation of...

Pax7 is back.

Skelet Muscle. 2014 Dec 14;4(1):24. doi: 10.1186/s13395-014-0024-4. eCollection 2014.

Two recent studies have reinvigorated the conversation regarding the role of Pax7 in adult satellite. Studies by Gunther et al (Cell Stem Cell 13:590-601, 2013) and Von Maltzhen et al (Proc Natl Acad Sci U S A 110:16474-16479) show...

BMP-9 expression in human traumatic heterotopic ossification: a case report.

Skeletal muscle

Grenier G, Leblanc E, Faucheux N, Lauzier D, Kloen P, Hamdy RC.
PMID: 24330639
Skelet Muscle. 2013 Dec 16;3(1):29. doi: 10.1186/2044-5040-3-29.

BACKGROUND: Heterotopic ossification (HO) is defined as the abnormal formation of mature bone in soft tissue, notably skeletal muscle. The morbidity of HO in polytraumatized patients impacts the functional outcome, impairs rehabilitation, and increases costs due to subsequent surgical...

C-terminal residues of skeletal muscle calsequestrin are essential for calcium binding and for skeletal ryanodine receptor inhibition.

Skeletal muscle

Beard NA, Dulhunty AF.
PMID: 25861445
Skelet Muscle. 2015 Feb 22;5:6. doi: 10.1186/s13395-015-0029-7. eCollection 2015.

BACKGROUND: Skeletal muscle function depends on calcium signaling proteins in the sarcoplasmic reticulum (SR), including the calcium-binding protein calsequestrin (CSQ), the ryanodine receptor (RyR) calcium release channel, and skeletal triadin 95 kDa (trisk95) and junctin, proteins that bind to...

Involvement of adiponectin in the pathogenesis of dystrophinopathy.

Skeletal muscle

Abou-Samra M, Lecompte S, Schakman O, Noel L, Many MC, Gailly P, Brichard SM.
PMID: 26257862
Skelet Muscle. 2015 Aug 07;5:25. doi: 10.1186/s13395-015-0051-9. eCollection 2015.

BACKGROUND: The hormone adiponectin (ApN) is decreased in the metabolic syndrome, where it plays a key pathogenic role. ApN also exerts some anti-inflammatory effects on skeletal muscles in mice exposed to acute or chronic inflammation. Here, we investigate whether...

In vitro stability of therapeutically relevant, internally truncated dystrophins.

Skeletal muscle

McCourt JL, Rhett KK, Jaeger MA, Belanto JJ, Talsness DM, Ervasti JM.

Skelet Muscle. 2015 Apr 28;5:13. doi: 10.1186/s13395-015-0040-z. eCollection 2015.

BACKGROUND: The X-linked recessive disease Duchenne muscular dystrophy (DMD) is caused by mutations in the gene encoding the protein dystrophin. Despite its large size, dystrophin is a highly stable protein, demonstrating cooperative unfolding during thermal denaturation as monitored by...
