Input: Consider Input: Question: Does increased expression of prostasin contribute to early-onset severe preeclampsia through inhibiting trophoblast invasion?
Answer: These findings suggest that prostasin may suppress the invasion process in preeclampsia by attenuating MMP2 and MMP9 secretion.

Output: yes


Input: Consider Input: Question: Is pKCε a negative regulator of PVAT-derived vessel formation?
Answer: PKCε negatively interferes with vessel progenitor differentiation via interaction with PAK-1.

Output: yes


Input: Consider Input: Question: Is omeprazole-induced acute interstitial nephritis related to CYP2C19 genotype or CYP2C19 phenotype?
Answer: There was discordance between CYP2C19 genotype and phenotype. However, up to 45% of healthy elderly subjects have a poor metabolizer phenotype. Thus neither CYP2C19 poor metabolizer genotype nor phenotype is a risk factor for OIAIN.


Output: no
