PKCδ maintains phenotypes of tumor initiating cells through cytokine-mediated autocrine loop with positive feedback.

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
The existence of tumor initiating cells (TICs) has been emerged as a good therapeutic target for treatment of glioblastoma that is the most aggressive brain tumor with poor prognosis. However, the molecular mechanisms that regulate the phenotypes of TICs still remain obscure. In this study, we found that PKCδ, among PKC isoforms, is preferentially activated in TICs and acts as a critical regulator for the maintenance of TICs in glioblastoma. By modulating the expression levels or activity of PKCδ, we demonstrated that PKCδ promotes self-renewal and tumorigenic potentials of TICs. Importantly, we found that the activation of PKCδ persists in TICs through an autocrine loop with positive feedback that was driven by PKCδ/STAT3/IL-23/JAK signaling axis. Moreover, for phenotypes of TICs, we showed that PKCδ activates AKT signaling component by phosphorylation specifically on Ser473. Taken together, we proposed that TICs regulate their own population in glioblastoma through an autocrine loop with positive feedback that is driven by PKCδ-dependent secretion of cytokines.
