Task: Answer Verification
Input (English): Question: Does in vivo treatment with granulocyte colony-stimulating factor delay apoptosis in human neutrophils by increasing the expression of the vacuolar proton ATPase?
Answer: In vivo G-CSF does not increase the amount of v-ATPase in neutrophils. Although G-CSF in vivo delays apoptosis, the mechanism(s) by which this occurs is not known.
Output (English): no
