Biohemija[uredi | uredi izvor]

Detaljna kinetička analiza transporta monokarboksilata u eritrocitima otkrila je da MCT1 djeluje preko uređenog mehanizma. MCT1 ima mjesto vezivanja supstrata otvoreno za vanćelijski matriks, koji prvo veže proton a zatim laktatni anion. Protein tada prolazi kroz konformacijsku promjenu u novu "zatvorenu" konformaciju koja izlaže i proton i laktat suprotnoj površini membrane, gdje se oslobađaju, prvo laktat, a zatim proton. Za neto transport mliječne kiseline, korak koji ograničava brzinu je povratak MCT1 bez vezanog supstrata u otvorenu konformaciju. Iz tog razloga, izmjena jednog monokarboksilata unutar ćelije s drugim izvan ćelije je znatno brža od neto transporta monokarboksilata kroz membranu.

Studije na životinjama[uredi | uredi izvor]

Pokazalo se da prekomjerna ekspresija MCT1 povećava efikasnost lijeka protiv raka koji se nalazi u kliničkim ispitivanjima pod nazivom 3-bromopiruvat u ćelijama raka dojke.^[9]

Klinički značaj[uredi | uredi izvor]

Većina slučajeva alveolskog mehkog sarkoma pokazuje PAS(+), rezistentne na dijastazu (PAS-D (+)) unutarcitoplazmatske kristale koji sadrže CD147 i monokarboksilatni transporter 1 (MCT1).^[10] Prekomjerna ekspresija MCT1 u pankreasnim beta ćelijama dovodi do hiperinsulinizma tokom vježbe.^[11]
