uniform manifold estimate projection ( UMAP ) implant of LUAD single-cell transcriptomes isolate from young and aged KP tumor label establish on previously specify transcriptionally distinct subset at 4, 12, and 17 week post-tumor initiation. The Numbers bespeak order of cell state progression. The survey detect the progression of young and aged cancer cell within the tumor over time.
MetaCell vicinity, group of similar cell represent discrete cell state, of 4-week-old KP LUAD tumor project onto the UMAP introduce in the previous survey. circle size match to the number of cell, while color mean the fraction of young and aged cell form a MetaCell vicinity. The enrichment of young cancer cell at the high-malleability cell state was note.
quantification of KRT8-high tdTomato+ LUAD cell at 4 week post-tumor initiation was conduct, screening difference between aged and young tumor. The survey aim to understand the variation in the presence of particular cell marker between different age group.
MetaCell analysis of KP LUAD tumor at 17 week post-tumor initiation also uncover difference in the distribution of young and aged cancer cell establish on cell state. The validation of these findings was make by immunohistochemical staining for particular marker. This analysis aim to supply penetration into the cellular composition of tumor at different phase of development.
The survey conduct experiment measure the molecular progression of KP LUAD cell in vitro. AT2 cell were isolate from aged vs. young KP-Cas9 mouse and transform ex vivo by lentiviral Cre recombinase. majority messenger_RNA sequence ( ribonucleic_acid-seq ) was perform over eight serial passage of tumor sphere. not-KP alveolar_consonant organoids from both aged and young AT2 cell were also include in the analysis.
projection of majority ribonucleic_acid-seq data from ex vivo transform young and aged AT2 cell in diffusion pseudotime space show distinct form establish on age and pseudotime point. The survey aim to understand how the molecular progression of cancer cell differ between young and aged person.
Boxplots were use to show the diffusion pseudotime distribution of young and aged ex vivo transform cell stratify harmonize to passage. This analysis aim to supply a ocular representation of the difference in cell progression between the two age group.
A heatmap expose the mean expression of alveolar_consonant epithelial lineage marker in young and aged ex vivo transform cell was show. The heatmap supply penetration into the expression form of particular gene associate to cancer progression in different age group.
In decision, the survey shed light on the difference in the molecular progression of LUAD cell between young and aged person. The findings underscore the importance of see age-associate factor in understanding cancer development and progression.
Overall, the research lend to our cognition of ripening and its impact on cancer biology, highlight the need for personalize treatment approach establish on age-associate difference in tumor characteristics.
