Optical Imaging of Matrix Metalloproteinases Activity in Prostate Tumors in Mice.
Article in Methods in molecular biology (Clifton, N.J.), 2022. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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 molecular characterization of cancer could have significant clinical benefits, including early diagnosis, making treatment decisions, and monitoring therapeutic response. In this regard, noninvasive assessment of expression/activity of specific molecules in tumors could be vital in managing cancer. Optical probes have demonstrated promise in the molecular imaging of cancer. Here, we have described a method to noninvasively assess the activity of matrix metalloproteinases (MMPs) in human prostate tumors in mice. We used an activatable probe MMPSense™ 750 FAST (MMPSense750) with fluorescent properties in the near-infrared (NIR) range with peak excitation at ~749 nm and peak emission ~775 nm. These optical properties offer the advantage of a higher depth of detection. This probe has shown immense potential in imaging MMPs activity in deeper tissue with high target-specific signal and low background autofluorescence. Therefore, this probe could be valuable in assessing MMPs activity in primary tumors and metastasis.
