The monocarboxylate transporter family—Structure and functional characterization [PDF]

IUBMB Life, 2011
AbstractMonocarboxylate transporters (MCTs) catalyze the proton‐linked transport of monocarboxylates such as L‐lactate, pyruvate, and the ketone bodies across the plasma membrane. There are four isoforms, MCTs 1–4, which are known to perform this function in mammals, each with distinct substrate and inhibitor affinities.

Acute exercise‐induced improvements in cognition: Role of cerebral blood flow and metabolism

Experimental Physiology, EarlyView.
Abstract Physical activity is widely recognized for its ability to promote brain health, with acute exercise transiently enhancing cognition and long‐term training attenuating cognitive decline. However, the mechanisms underlying these benefits remain incompletely understood.

Effects of lactate administration on mitochondrial enzyme activity and monocarboxylate transporters in mouse skeletal muscle

Physiological Reports, 2019
Growing evidence shows that lactate is not merely an intermediate metabolite, but also a potential signaling molecule. However, whether daily lactate administration induces physiological adaptations in skeletal muscle remains to be elucidated.

MCT1‐mediated bidirectional propionate transport across human placental syncytiotrophoblast layer: insights from a trophoblast stem cell‐derived barrier model

The Journal of Physiology, EarlyView.
Abstract figure legend Propionate in the fetal circulation is thought to originate from fermentation of dietary fibre by the maternal gut microbiota. However, the mechanism of transplacental transport has remained unclear. Here, we measured propionate permeability using a placental barrier model generated by differentiating human placental trophoblast ...

A review of xenobiotic membrane transporter expression within the human placenta: Lessons gained from primary tissue and in vitro methodologies

The Journal of Physiology, EarlyView.
Abstract figure legend A summary of the current knowledge around membrane transporter expression in the most widely used in vitro models of human trophoblasts, including primary placental tissue, cancer cell lines and trophoblast stem cells, as well as the techniques to attempt to mimic the human placenta in vivo.

Maternal nutrition as a key determinant of placental and developing blood–brain barrier xenobiotic protective functions

The Journal of Physiology, EarlyView.
Abstract figure legend Suboptimal maternal nutrition alters placental and developing blood–brain barrier (BBB) protective function and is associated with increased fetal brain vulnerability. In the placenta, nutritional adversity may reduce the exchange surface area and promote meta‐inflammation, compromising barrier efficiency in a model‐ and context ...

Virus‐specific alterations in placental structure and transporter expression following maternal arbovirus infection

The Journal of Physiology, EarlyView.
Abstract figure legend Arboviruses induce virus‐specific alterations in placental structure and functional markers. Chikungunya virus (CHIKV) exposure was associated with reduced syncytiotrophoblast and syncytial knot areas, increased cytotrophoblast proliferation (Ki‐67) and thyroid transporter (MCT8) expression, reduced protective (P‐gp and BCRP ...

Monocarboxylate transporters and their functions in the retina

Acta Ophthalmologica, 2015
SummaryMonocarboxylate transporters (MCTs) have important functions in healthy tissues, being involved in the transmembrane transport of lactate and other monocarboxylic acids. MCTs are a family of transporters which is presently composed by 14 members, but only MCT1–4 have been biochemically characterized.

Mitochondrial physiology in cardiac muscle of deer mice native to high altitude

The Journal of Physiology, EarlyView.
Abstract figure legend High‐altitude deer mice exhibited evolved changes in mitochondrial energy metabolism and reactive oxygen species (ROS) management that may support cardiac performance under cold hypoxic conditions. High‐altitude mice had increased activity of lactate dehydrogenase (LDH) in the heart, probably enhancing the capacity for lactate ...

Diving into the unknown: Evidence of enhanced skeletal muscle lactate efflux potential and blood–muscle exchange in competitive breath‐hold divers

The Journal of Physiology, EarlyView.
Abstract figure legend Competitive breath‐hold divers exhibit skeletal muscle characteristics indicative of enhanced blood‐muscle exchange capacity and increased lactate efflux potential. Top left: Participant characteristics, matched for age, height, body mass, and maximal oxygen uptake (V̇O2max${\dot{\mathrm{V}}}\rm{O}_{\rm{2max}}$).
