Function
- secreted signal that acts globally to specify positional identity along the anterior/posterior axis during development
- role in patterning both mesodermal & neural tissues & in establishing the skeletal pattern
- inhibitor of nerve tissue growth[4][5]
- arrest of progenitor cell-cycle in the G1 phase
- interacts with ALK4 & ALK5 to activate SMAD3-dependent genes[6]
- may upregulate expression of Hoxc10[6]
- inhibits proliferation of olfactory receptor neuron progenitors to regulate the number of olfactory receptor neurons in the olfactory epithelium by inducing p27(Kip1) & reversible cell cycle arrest in progenitors[7]
- controls the numbers of retinal ganglion cells, amacrine cells & photoreceptor cells during development of the retina[8]
- in the retina, does not affect proliferation of progenitors
- controls duration of expression of Math5, a gene that confers competence for retinal ganglion cell genesis
- thus controls temporal windows for progenitor cell competence[8]
- increases expression of SERCA2 in myocardium, an enzyme necessary for relaxation during diastole
- negatively regulates
- may be regulated by WFIKKN2
* perhaps in general, inhibits proliferation, promotes differentiation
Structure
- homodimer; disulfide-linked (putative)
- belongs to the TGF-beta family
- homologous to myostatin & may play similar cellular role[4]
- 90% identical in their amino acid sequence[5]
- 89% homlogous to GDF8[12]
Compartment
secreted (probable)
Expression
- GDF11 gene expression & protein abundance decreases with age[2][4]
- GDF11 plasma levels may increase with age[11]
- GDF11 plasma levels decline with age in mice, rats, horses & sheep[12]
Comparative biology
- GDF11 reverses LV diastolic dysfunction in mice[1]
- blood of young mice contains substances that reverse aging processes in heart muscle, skeletal muscle, & brain
- one of these substances is GDF11[3]
- GDF11 inhibits muscle regeneration in mice[11]
- effect may be dose-sensitive (therapeutic window)[11]
- one dose may enhance muscle regeneration, but a 3-fold dose increase may inhibit muscle regeneration[11]
- effect may be dose-sensitive (therapeutic window)[11]
- plasma levels of GDF11 do not decline with age[11]*
- it is noted that there may be several forms of GDF11 in mice & that some forms may decline with age while others may increase[11]
- plasma GDF11 & GDF11 mRNA in muscle increase with age in rats[11]
- circulating levels of GDF11 decline with age in mice, rats, horses & sheep[12]
- in patients with stable ischemic heart disease, higher GDF11/GDF8 (myostatin) levels are associated with lower risk of cardiovascular events & death[13]*
* ref[12] claims increase in GDF11 levels with age observed in ref[11] are a result of cross-reactivity of the anti-GDF11 antibody used in ref[11] with immunoglobulin
