Leptin From Fibro-Adipogenic Progenitor Cells (FAPs) Regulates Masseter Muscle Disuse Atrophy and Ectopic Fat Accumulation. [PDF]

J Cachexia Sarcopenia Muscle
ABSTRACT Background Excessive fat accumulation in muscles with disuse atrophy may impair muscle physiologic function and exacerbate the progression of atrophy, with causes largely unexplored. Evidence indicates leptin plays a crucial role in regulating skeletal muscle fat metabolism.

Relationship of aging, skeletal muscle mass, and tooth loss with masseter muscle thickness

BMC Geriatrics, 2018
Background Previous studies have reported a relationship between masseter muscle thickness and tooth loss or limb muscle thickness. However, it is not yet known whether masseter muscle thickness is related to appendicular skeletal muscle mass, and grip ...

Transcription factor MITF regulates masseter muscle growth and development [PDF]

Physiological Reports
The microphthalmic mouse with a mutation at the locus of the microphthalmia‐associated transcriptional factor (MITF) gene exhibits masticatory dysfunction due to impaired masseter muscle development and needs to be fed with powdered diet.

Applicability of the masseter muscle as a nutritional biomarker

Medicine, 2020
Nutritional assessment is feasible with computed tomography anthropometry. The abdominal muscle at the L3 vertebra is a well-known nutritional biomarker for predicting the prognosis of various diseases, especially sarcopenia.

An ultrasonographic evaluation of masseter muscle thickness in different dentofacial patterns

Indian Journal of Dental Research, 2012
Objectives: The aim of this study is to compare the masseter muscle thickness in different vertical dentofacial patterns and identify the possible sexual dimorphism and also to correlate masseter muscle thickness with craniofacial morphology using ...

Protective Effects of Clenbuterol against Dexamethasone-Induced Masseter Muscle Atrophy and Myosin Heavy Chain Transition. [PDF]

PLoS ONE, 2015
Glucocorticoid has a direct catabolic effect on skeletal muscle, leading to muscle atrophy, but no effective pharmacotherapy is available. We reported that clenbuterol (CB) induced masseter muscle hypertrophy and slow-to-fast myosin heavy chain (MHC ...
