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 protein family. [8] [9] Myostatin is assembled and produced in skeletal muscle before it is released into the blood stream. [10]
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 ]
The mutation affects the body's repair mechanism, causing fibrous tissue including muscle, tendons, and ligaments to become ossified, either spontaneously or when damaged as the result of trauma. In many cases, otherwise minor injuries can cause joints to become permanently fused as new bone forms, replacing the damaged muscle tissue. This new ...
After being produced, the stability and distribution of the different transcripts is regulated (post-transcriptional regulation) by means of RNA binding protein (RBP) that control the various steps and rates controlling events such as alternative splicing, nuclear degradation (), processing, nuclear export (three alternative pathways), sequestration in P-bodies for storage or degradation and ...
The JAK-STAT pathway in cytokine receptor signalling can activate STATs, which can bind to DNA and allow the transcription of genes involved in immune cell division, survival, activation and recruitment. For example, STAT1 can enable the transcription of genes which inhibit cell division and stimulate inflammation. [2]
Joints are controlled by two opposing sets of muscles called extensors and flexors, that work in synchrony for smooth movement. When a muscle spindle is stretched, the stretch reflex is activated, and the opposing muscle group must be inhibited to prevent it from working against the contraction of the homonymous muscle. This inhibition is ...
[1] [2] Gene silencing can occur during either transcription or translation and is often used in research. [ 1 ] [ 2 ] In particular, methods used to silence genes are being increasingly used to produce therapeutics to combat cancer and other diseases, such as infectious diseases and neurodegenerative disorders .
This list of manually curated human transcription factors is taken from Lambert, Jolma, Campitelli et al. [1] It was assembled by manual curation. More detailed information is found in the manuscript and the web site accompanying the paper (Human Transcription Factors)
