The best characterized molecular abnormality in pituitary adenomas involves which of the following?
A) Cell surface receptors
B) G-proteins mediating signal transduction
C) Adenylate cyclase related cytoplasmic effectors
D) Nuclear receptors
E) DNA repair enzymes

Question

Quizplus · Accepted Answer

G-protein mutations are the best characterized molecular abnormalities found in pituitary adenomas. G-proteins are involved in the transmission of signals from cell surface receptors stimulated with hypothalamic release factors and intracellular effectors, such as the adenylate cyclase system.
