The Claim
Recombinant human TSH induces a strong cAMP response in most differentiated orbital fibroblasts from patients with Graves' ophthalmopathy but does not stimulate hyaluronan synthesis in nearly all cases, demonstrating a dissociation between cAMP signaling and hyaluronan production.
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 cells from patients with Graves' ophthalmopathy, recombinant human TSH triggers a strong cAMP signal but does not cause hyaluronan production in nearly all cases, showing that these two biological responses are not linked.
See the scientific wording
Recombinant human TSH induces a strong cAMP response in most differentiated orbital fibroblasts from patients with Graves' ophthalmopathy but fails to stimulate hyaluronan synthesis in nearly all cases, indicating a dissociation between cAMP signaling and hyaluronan production.
When the TSH receptor on eye tissue cells is activated by the hormone TSH, it turns on a chemical signal called cAMP, but this does not cause the cells to produce the swelling substance hyaluronan. A different activator, found in the blood of people with Graves' disease, can turn on hyaluronan production without relying on cAMP, showing that cAMP alone is not enough to make the swelling substance.
What the research says
1 studyIn eye cells from people with Graves' disease, the hormone TSH turns on a signal called cAMP, but it doesn't make the gooey substance (hyaluronan) that causes swelling. This means those two things aren't connected, even though they both involve the same receptor.
