Super-Resolution Microscopy Reveals Alterations in Clathrin Structure in Human Cancer Tissue.

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
Super-resolution microscopy holds great promise for detailed structural analysis of proteins, yet its application in the investigations of protein structures in situ remains sparse. Clathrin-coated pit-mediated endocytosis (CME) plays a key role in human cancer. This study aimed to discover whether there are structural changes in clathrin pits in cancer. Immunofluorescence combined with super-resolution structured illumination microscopy (SR-SIM) on normal and cancerous prostate tissue was used to reveal novel details of clathrin structure and biology. Clathrin (heavy-chain) plaques and pits, expression of adaptor protein 2 (a clathrin adaptor protein), and epidermal growth factor receptor (a receptor target for CME) at nanometer scale in human tissue were observed in situ with immunofluorescence-SR-SIM. The size of the clathrin pits in high-grade cancer was greater compared with that in low-grade or normal prostate tissue. These results demonstrate that SR-SIM can be used to identify protein structures at high resolution in clinical tissue sections and there is an increased cargo capacity due to the increase in the size of clathrin pits as a mechanism that facilitates aggressiveness of cancer. These results shed new light on the pathology of cancer and the role CME via clathrin may play in carcinogenesis.
