Question

A researcher is studying a cell line with a mutation that reduces the activity of cyclic nucleotide phosphodiesterase (PDE). What effect would this mutation likely have on cAMP levels and cellular signaling?

Accepted Answer

Increased cAMP levels, leading to prolonged activation of signaling pathways.

Answer

No change in cAMP levels, as PDE does not affect cAMP.

Answer

Increased cAMP levels, leading to inhibition of signaling pathways.

Answer

Decreased cAMP levels, leading to reduced activation of signaling pathways.
