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

Transient expression levels, vector dissemination and toxicities associated with adenoviral vectors have prompted the usage of matrices for localized and controlled gene delivery. Two recombinant silk-elastinlike protein polymer analogues, SELP-47K and SELP-415K, consisting of different lengths and ratios of silk and elastin units, were previously shown to be injectable hydrogels capable of matrix-mediated controlled adenoviral gene delivery. Reported here is a study of spatiotemporal control over adenoviral gene expression with these SELP analogues in a human tumor xenograft model of head and neck cancer using whole animal imaging. Real-time images of viral expression levels indicate that polymer concentration and polymer structure are predominant factors that affect viral release and, thus, viral transfection. Decrease in polymer concentration and increase in polymer elastin content results in greater release, probably due to changes in the network structure of the hydrogel. To better understand this relationship, macro- and microstructural properties of the hydrogels were analyzed using dynamic mechanical analysis (DMA) and transmission electron microscopy (TEM). The results confirm that the concentration and the elastin content of the protein polymer affect the pore size of the hydrogel by changing the physical constraints of the SELP fibril network and the degree of hydration of the SELP fibrils. The potential to modulate viral release using SELP hydrogel delivery vehicles that can be injected intratumorally by minimally invasive techniques holds significant promise for the delivery of therapeutic viruses.
