Transcription factor 7-like 2 (TCF7l2) regulates CNS myelination separating from its role in upstream oligodendrocyte differentiation.

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.
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
Oligodendrocyte progenitor cells (OPCs) differentiation into oligodendrocytes (OLs) and subsequent myelination are two closely coordinated yet differentially regulated steps for myelin formation and repair in the CNS. Previously thought as an inhibitory factor by activating Wnt/beta-catenin signaling, we and others have demonstrated that the Transcription factor 7-like 2 (TCF7l2) promotes OL differentiation independent of Wnt/beta-catenin signaling activation. However, it remains elusive if TCF7l2 directly controls CNS myelination separating from its role in upstream oligodendrocyte differentiation. This is partially because of the lack of genetic animal models that could tease out CNS myelination from upstream OL differentiation. Here, we report that constitutively depleting TCF7l2 transiently inhibited oligodendrocyte differentiation during early postnatal development, but it impaired CNS myelination in the long term in adult mice. Using time-conditional and developmental-stage-specific genetic approaches, we further showed that depleting TCF7l2 in already differentiated OLs did not impact myelin protein gene expression nor oligodendroglial populations, instead, it perturbed CNS myelination in the adult. Therefore, our data convincingly demonstrate the crucial role of TCF7l2 in regulating CNS myelination independent of its role in upstream oligodendrocyte differentiation.
