Loss of
myostatin function is associated with an increase in muscle mass in mice, cows, and humans.
The muscle - building and fat - burning effects of human growth hormone are thought to be caused by GH's interference with
myostatin function [21], and the muscle destroying effects of cortisol appear to be associated with higher concentrations of myostatin [22].
If myostatin does act systemically, the implication would be that local control of muscle growth can be influenced at least in part by myostatin being produced elsewhere in the body and
that myostatin functions precisely as a chalone, as originally hypothesized by Bullough [25], [26] for the control for tissue growth in general.

To determine whether the FLRG transgene was causing increased muscle growth by blocking
myostatin activity, I examined the effect of combining the FLRG transgene with a loss - of -
function mutation in the
myostatin gene.
The
function of
myostatin appears to have been conserved across species, as inactivating mutations in the
myostatin gene have been demonstrated to cause increased muscling in cattle [8]--[11], sheep [12], dogs [13] and humans [14].
There have been human trials of
myostatin blockade via antibodies, for example, and there are even a few well - muscled natural human
myostatin loss of
function mutants.
From a biological point of view, the primary
function of
myostatin is the control of metabolism in order to support the immune system.
