Lp(a) is a cholesterol-rich lipoprotein synthesized in the liver. It consists of apolipoprotein B100 and apolipoprotein(a) (apo(a)) linked by a disulfide bond. Apo(a) is encoded by LPA gene, one of the most polymorphic genes in humans, as more than 40 gene variants have been discovered. Lp(a) levels are 90% genetically determined by variants in the LPA gene and are in the atherogenic range (&gt; 300 mg/L) in 20 to 30% of the population. In the last decade, immense progress has been made in understanding the mechanisms involved in the synthesis and metabolism of Lp(a). This has also improved the understanding of the pathophysiology of Lp(a) and the factors affecting Lp(a) concentration. Although the determination of Lp(a) is not yet standardized, from a clinical point of view it allows the identification of individuals at increased risk for cardiovascular diseases. To reduce risk, promising new therapeutic options are currently being developed to directly lower Lp(a) concentrations by targeting LPA mRNA. The aim of this article is to present the latest knowledge on the structure, synthesis, metabolism, pathophysiological mechanisms, and therapeutic options for lowering Lp(a) and to address challenges in determining Lp(a) concentration in clinical laboratories</dc:description><dc:description xml:lang="sl">Koncentracija lipoproteina(a) (Lp(a)) je določena genetsko in je neodvisni dejavnik tveganja za srčno-žilne bolezni. Lp(a) je s holesterolom bogat lipoproteinski delec, ki nastaja v jetrih. Sestavljen je iz apolipoproteina B100 in apolipoproteina(a) (apo(a)), ki sta povezana z disulfidno vezjo. Apo(a) kodira LPA, ki je eden najbolj polimorfnih genov pri človeku, saj je bilo identificiranih že več kot 40 genetskih variant. Koncentracija Lp(a) je v 90 % genetsko določena preko variant v genu LPA in je v aterogenem območju (&gt; 300 mg/L) prisotna pri 20 do 30 % populacije. V zadnjem desetletju je prišlo do velikega napredka pri razumevanju mehanizmov, ki so vpleteni v sintezo in presnovo Lp(a), kar je izboljšalo tudi razumevanje patofiziologije Lp(a) in dejavnikov, ki vplivajo na njegovo koncentracijo. Kljub temu da določanje Lp(a) še ni standardizirano, s kliničnega vidika zadostuje za prepoznavanje posameznikov s povečanim tveganjem za srčno-žilne bolezni. Pri teh posameznikih je ključno zmanjšanje tveganja, zato so v postopku razvoja nove, obetavne terapevtske možnosti za zniževanje koncentracije Lp(a), ki so usmerjene proti mRNA gena LPA. Namen prispevka je predstavitev najnovejših ugotovitev o strukturi, sintezi, presnovi, patofizioloških mehanizmih in terapevtskih možnosti za zniževanje koncentracije Lp(a) ter izpostaviti izzive pri njegovem določanju v kliničnih laboratorijih</dc:description><edm:type>TEXT</edm:type><dc:type xml:lang="sl">znanstveno časopisje</dc:type><dc:type xml:lang="en">journals</dc:type><dc:type rdf:resource="http://www.wikidata.org/entity/Q361785" /></edm:ProvidedCHO><ore:Aggregation rdf:about="http://www.dlib.si/?URN=URN:NBN:SI:DOC-LF3WZSH3"><edm:aggregatedCHO rdf:resource="URN:NBN:SI:DOC-LF3WZSH3" /><edm:isShownBy rdf:resource="http://www.dlib.si/stream/URN:NBN:SI:DOC-LF3WZSH3/96f6cc6599d0-bfce24-4-11d004-a672579/PDF" /><edm:rights rdf:resource="http://rightsstatements.org/vocab/InC/1.0/" /><edm:provider>Slovenian National E-content Aggregator</edm:provider><edm:dataProvider xml:lang="en">National and University Library of Slovenia</edm:dataProvider><edm:object rdf:resource="http://www.dlib.si/streamdb/URN:NBN:SI:DOC-LF3WZSH3/maxi/edm" /><edm:isShownAt rdf:resource="http://www.dlib.si/details/URN:NBN:SI:DOC-LF3WZSH3" /></ore:Aggregation></rdf:RDF>
