Co-first authors: Yan-Fei Wang and Ruo-Yu He.
Author contributions: Cao YF designed and supervised the study, and drafted the manuscript; Wang YF and He RY took the responsibility for statistical analyses and the manuscript; Xu C and Li XL performed manuscript reviewing and editing; all authors have read and approved the article. The reasons for designating Wang YF and He RY as co-first authors are twofold. Wang YF is responsible for all bioinformatics computations and analyses, including handling data. He RY collects samples and conducts experiments. They contributed efforts of equal substance throughout the research process. Second, this study was a team effort, and the co-first authorship accurately reflects how responsibilities and work were shared during the study and paper completion. This helps with effective communication and managing post-submission tasks, ultimately improving the paper's quality and reliability. Summary, we believe that designating Wang YF and He RY as co-first authors of is fitting for our manuscript as it accurately reflects our team's collaborative spirit, equal contributions, and diversity.

Core Tip

Core Tip: Ulcerative colitis (UC), a chronic inflammatory bowel disease linked to colorectal cancer, was investigated using single-cell RNA sequencing technology. The study unveiled sustained upregulation of inflammatory response pathways and characterized damaged endothelial cells during UC progression. Notably, the downregulation of phospholysine phosphohistidine inorganic pyrophosphate phosphatase (LHPP) exhibited a negative correlation with signal transducer and activator of transcription 3. LHPP's significant downregulation in UC patient tissues and plasma suggests its potential as a therapeutic target. The findings highlight LHPP as a key target in UC and emphasize its role in inflammation regulation, offering insights for potential therapeutic interventions.
