Summary
Objective
Amphiregulin(AREG)andFractalkine(FRACT),areinvolvedinavarietyofnormalandpathologicalprocesses,andarebothsuggestedtoberelevanttojointdegeneration.Theaimsofthepresentstudyincluded
(1)testingassociationbetweencirculatinglevelsofthesebiomarkersandjointpathologies,
(2)evaluationoftheputativegeneticandfamilialfactors’effectonAREGandFRACTvariability.
Design
Thestudywasconductedinthefamily-basedsampleof923Caucasianindividuals.VariancecomponentanalysiswasusedtoassesscontributionofgeneticandenvironmentalfactorstovariabilityofAREGandFRACTconcentration.
Results
ThemeanlevelsofFRACTweresignificantlyhigherintheaffectedgroupwitharthropathies(synovialjointsosteoarthritis(OA)anddiscdegenerativedisease,DDD)theninthecontrolgroup(P
<
0.0004).CirculatingAREGlevelswerehigherinDDD(P
=
0.0272).GeneticfactorsconstitutedthemainsourceoftheinterindividualdifferencesoftheAREGandFRACTlevelsinoursample,andexplained29.68%and41.68%ofthetotalvariation,respectively.ThephenotypiccorrelationbetweenAREGandFRACTwassubstantial(r
0.55,P
0.0001)andwasassociatedwithbothcommongeneticandenvironmentalfactors.Specifically,30%ofthephenotypiccorrelationbetweenAREGandFRACTwasduetocommongeneticeffects.
Conclusions
FurtherstudiesarerequiredtoassessrelevancyofFRACTtoclinicaldiagnosisandprognosisofarthropathies,toinvestigatethemechanismsbehindtheobservedphenotypicandgeneticcovariationamongthestudiedbiomarkers,andtoexplorespecificgeneticpolymorphismsaffectingAREGandFRACTvariation.
