Megjegyzések:Pituitary adenylate cyclase-activating polypeptide(PACAP), a neuropeptide with survival-promotingactions, has been observed in endocrine organs and isthought to play a role in reproductive functions, includingpregnancy. PACAP occurs in two forms, 27 and 38 aminoacid residues, with PACAP38 being the predominant formin human tissues. In the present study, we determined theconcentrations of PACAP38 and PACAP27 in firsttrimesterand full-term human placentas using radioimmunoassay.We found high levels of PACAP38 and lowerlevels of PACAP27 in different parts of the full-term humanplacenta. PACAP38 content increased in the placentaduring pregnancy, both on the maternal side and on thefetal side. The effects of PACAP on the survival of JARhuman choriocarcinoma cells were investigated using flowcytometry and MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide) cell viability assay in cellsexposed to the widely used chemotherapeutic agentmethotrexate (MTX). It was found that PACAP neitherinfluenced the survival of JAR cytotrophoblast cells noraffected cellular response to the death-inducing effect of thechemotherapeutic agent MTX. The present observationsfurther support the significance of PACAP in the humanplacenta. The observation that PACAP did not influence theeffects of MTX may have future clinical importance,showing that PACAP does not decrease the effects ofcertain chemotherapeutic agents.Keywords JAR .
