Proteome-Wide Investigation of Proline Hydroxylation in Pancreatic Ductal Adenocarcinoma Using DiLeu Isobaric Labeling Strategy.

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
Pancreatic ductal adenocarcinoma (PDAC) is a highly aggressive malignancy characterized by a dense fibrotic stroma intertwined with a collagen-rich extracellular matrix (ECM), which significantly contributes to tumor progression. In this study, we developed a high-throughput quantitative method that integrates enhanced hydrophilic interaction liquid chromatography (HILIC) with modified elution conditions and 12-plex N,N-dimethyl leucine (DiLeu) isobaric tags, facilitating efficient multiplexed quantitative analysis of hydroxyproline. This approach was applied to human pancreatic samples and resulted in the identification of 194 hydroxyproline peptides from 157 hydroxyproline sites and 59 proline-hydroxylated proteins, representing the first and the largest hydroxyproline proteomics dataset reported for the pancreas to date. This dataset lays a molecular foundation for understanding the structure-function relationships of hydroxyproline-containing proteins and their roles in pancreatic physiology and pathology. We then apply this strategy to investigating proline hydroxylation alterations in benign pancreatic tumors, PDAC, and their normal adjacent tissues (NAT). Our findings suggest significant biological functions related to proline hydroxylation, including altered patterns of key proteins such as collagen alpha-1(I) chain and collagen alpha-1(XII) chain. These proteins emerge as potential targets for further studies on proline hydroxylation in PDAC, potentially elucidating its role in modifying protein structures and influencing cancer progression.
