The Claim
TSH-secreting pituitary adenomas exhibit undetectable thyroid hormone receptor alpha and beta proteins in tumor tissue despite normal levels of corresponding mRNA, indicating a post-transcriptional defect in receptor protein expression that may impair thyroid hormone feedback regulation of TSH 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 tumors that produce excess TSH hormone, the proteins that respond to thyroid hormones are not detectable, even though the genetic instructions to make them are present. This suggests a problem in converting those instructions into functional proteins, which could disrupt the body's normal control of TSH levels.
See the scientific wording
TSH-secreting pituitary adenomas lack detectable thyroid hormone receptor alpha and beta proteins in tumor tissue, despite normal levels of corresponding mRNA, suggesting a post-transcriptional defect in receptor protein expression that may impair thyroid hormone feedback regulation of TSH production.
Thyroid hormone receptor proteins are not made in TSH-secreting tumor cells, even though the genetic instructions for them are present. Without these proteins, thyroid hormone cannot signal the tumor to stop producing TSH, so TSH levels stay high and keep the thyroid overactive.
What the research says
1 studyIn these rare tumors that make too much TSH, the body’s instructions to make thyroid hormone sensors are fine, but the sensors themselves don’t get built. Without these sensors, the brain can’t tell the tumor to stop making TSH, so it keeps producing too much.
