Title:Theeffectsofethanolonexpressionofneuropeptidesandapoptosis-relatedgenesinhumanbonemarrowmesenchymalstemcells.

Background:

Alcoholconsumptionhasbeenlinkedwithvariousphysiologicalandpsychologicalconditions,includingdecreasedbonedensityandincreasedriskoffractures.Thebonemarrowisaprimarytissueaffectedbyalcoholconsumption,asitisresponsibleforhematopoiesisandcangiverisetomesenchymalstemcells(MSCs).MSCshavetheabilitytodifferentiateintovariouscelltypes,includingosteoblasts,whichareresponsibleforboneformation.TheimpactofethanolonthefunctionsofMSCsandosteoblastsisstillnotfullyunderstood.

Objective:

Thisstudyaimstoinvestigatetheeffectsofethanolontheexpressionofneuropeptidesandapoptosis-relatedgenesinhumanbonemarrowmesenchymalstemcells.

Methods:

Humanbonemarrowmesenchymalstemcellswillbeisolatedandculturedinvitro.Thecellswillbetreatedwithdifferentconcentrationsofethanolfordifferenttimeperiodstomimicchronicalcoholexposure.Theexpressionofneuropeptides,includingsubstanceP,calcitoningene-relatedpeptide(CGRP),andtyrosinehydroxylase(TH),willbemeasuredusingquantitativepolymerasechainreaction(qPCR)andenzyme-linkedimmunosorbentassay(ELISA).Apoptosis-relatedgenes,includingBcl-2,Bax,andcaspase-3,willalsobemeasuredusingqPCR.

ExpectedOutcomes:

Itisexpectedthatethanolexposurewillleadtochangesintheexpressionofneuropeptidesandapoptosis-relatedgenesinhumanbonemarrowmesenchymalstemcells.Specifically,itishypothesizedthatethanolexposurewilldecreasetheexpressionofneuropeptidesandincreasetheexpressionofapoptosis-relatedgenes,whichcouldultimatelyleadtodecreasedboneformationandincreasedriskofbonefractures.

Conclusion:
