1 · What the graph read from it

What it found

Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.

The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.

2 · The registry

The trial behind it

Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.

Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract

The human SLC29 family of proteins contains four members, designated equilibrative nucleoside transporters (ENTs) because of the properties of the first-characterised family member, hENT1. They belong to the widely-distributed eukaryotic ENT family of equilibrative and concentrative nucleoside/nucleobase transporters and are distantly related to a lysosomal membrane protein, CLN3, mutations in which cause neuronal ceroid lipofuscinosis. A predicted topology of 11 transmembrane helices with a cytoplasmic N-terminus and an extracellular C-terminus has been experimentally confirmed for hENT1. The best-characterised members of the family, hENT1 and hENT2, possess similar broad substrate specificities for purine and pyrimidine nucleosides, but hENT2 in addition efficiently transports nucleobases. The ENT3 and ENT4 isoforms have more recently also been shown to be genuine nucleoside transporters. All four isoforms are widely distributed in mammalian tissues, although their relative abundance varies: ENT2 is particularly abundant in skeletal muscle. In polarised cells ENT1 and ENT2 are found in the basolateral membrane and, in tandem with concentrative transporters of the SLC28 family, may play a role in transepithelial nucleoside transport. The transporters play key roles in nucleoside and nucleobase uptake for salvage pathways of nucleotide synthesis, and are also responsible for the cellular uptake of nucleoside analogues used in the treatment of cancers and viral diseases. In addition, by regulating the concentration of adenosine available to cell surface receptors, they influence many physiological processes ranging from cardiovascular activity to neurotransmission.
