Which of the following mutations would most likely contribute to the development of a hormone-secreting pituitary adenoma?
1
A mutation that increases the expression of the Gs alpha subunit, leading to continuous stimulation of adenylate cyclase.
2
A deletion mutation in the gene coding for the cortisol receptor, leading to inadequate cortisol feedback inhibition.
3
A nonsense mutation in the gene encoding growth hormone, leading to a truncated, non-functional hormone.
4
An insertion mutation in the gene for prolactin, increasing the stability of prolactin mRNA and thus prolactin levels.
