Myostatin-related muscle hypertrophy is a rare genetic condition characterized by reduced body fat and increased skeletal muscle size. [1] Affected individuals have up to twice the usual amount of muscle mass in their bodies, but increases in muscle strength are not usually congruent. [ 2 ]
Myostatin (also known as growth differentiation factor 8, abbreviated GDF8) is a protein that in humans is encoded by the MSTN gene. [6] Myostatin is a myokine that is produced and released by myocytes and acts on muscle cells to inhibit muscle growth. [7] Myostatin is a secreted growth differentiation factor that is a member of the TGF beta ...
Statin-associated autoimmune myopathy (SAAM), also known as anti-HMGCR myopathy, is a very rare form of muscle damage caused by the immune system in people who take statin medications. [1] However, there are cases of SAAM in patients who have not taken statin medication, and this can be explained by the exposure to natural sources of statin ...
Myostatin, a member of the transforming growth factor superfamily, is a negative regulator of bone and muscle growth. It may also play a role in obesity, insulin resistance, cardiovascular disease, and chronic kidney disease. [1] [2]
Other factors that play a role in muscle loss (or maintenance) while on weight loss meds include whether you have certain health conditions (like heart disease and diabetes) as well as the type of ...
They recommended selective use of low-to-moderate doses statins in the same adults who have a calculated 10-year cardiovascular disease event risk of 7.5–10% or greater. [22] In people over the age of 70, statins decrease the risk of cardiovascular disease but only in those with a history of heavy cholesterol blockage in their arteries. [24]
Spastic hypertonia involves uncontrollable muscle spasms, stiffening or straightening out of muscles, shock-like contractions of all or part of a group of muscles, and abnormal muscle tone. It is seen in disorders such as cerebral palsy, stroke, and spinal cord injury. Rigidity is a severe state of hypertonia where muscle resistance occurs ...
Muscle hypertrophy or muscle building involves a hypertrophy or increase in size of skeletal muscle through a growth in size of its component cells. Two factors contribute to hypertrophy: sarcoplasmic hypertrophy, which focuses more on increased muscle glycogen storage; and myofibrillar hypertrophy, which focuses more on increased myofibril ...
