The Claim
Overexpression of FSP27 in human adipocytes inhibits growth hormone-induced phosphorylation of PPARγ at Ser273, prevents the nuclear export of PPARγ, and reduces lipolysis, demonstrating that FSP27 functions as a regulatory inhibitor of this signaling pathway.
What the research says
Supports is higher
Support is ahead, but a single strong opposing study can change this.
These are independent scores, not a percentage. Higher-grade studies count more, so a single strong opposing study can outweigh several weaker ones.
In human fat cells, increased levels of the protein FSP27 block a specific chemical modification of PPARγ triggered by growth hormone, prevent PPARγ from leaving the nucleus, and decrease the breakdown of fat.
See the scientific wording
Overexpression of FSP27 in human adipocytes blocks growth hormone-induced phosphorylation of PPARγ at Ser273, prevents its nuclear export, and reduces lipolysis, indicating FSP27 acts as a protective regulator of this pathway.
When growth hormone signals fat cells, it turns on a chain reaction that moves a key fat-regulating protein out of the nucleus, which turns off a gene that keeps fat stored. If FSP27 is present in high amounts, it blocks this chain reaction, keeping the fat-regulating protein inside the nucleus, so the gene stays active and fat breakdown stops.
What the research says
1 studyStudy: Growth hormone acts along the PPARγ-FSP27 axis to stimulate lipolysis in human adipocytes.
When scientists added more FSP27 protein to human fat cells, it stopped growth hormone from triggering fat breakdown, like putting a brake on the process. This shows FSP27 normally helps keep fat stored by blocking this signal.
