Telomeres: The EPI-Ending

Current Opinion in Plant Biology
Telomeres are essential chromosomal structures that protect genome integrity and play a central role in aging and cell proliferation. In plants, the epigenetic landscape of telomeres and their adjacent subtelomeric regions has emerged as a critical component regulating telomere function and genome organization.

Epis need not be dense

Theoretical Computer Science, 1982
AbstractIn [6] and [7] Meseguer conjectured that in the category Pos(ω) of ω-complete posets and ω-continuous maps the epis are exactly the dense maps. This paper exhibits a counter-example to Meseguer's conjecutre, draws a number of negative conclusions and strengthens another of Meseguer's results.

Single‐Cell Transcriptomic Analysis of Tumor Heterogeneity and the Microenvironment in Pseudomyxoma Peritonei

Advanced Science, EarlyView.
This study presents a single‐cell atlas of pseudomyxoma peritonei spanning primary and paired metastatic lesions. Distinct epithelial substates, stromal remodeling, immune exclusion, lipid metabolic reprogramming, and a candidate angiogenic network were identified in metastatic lesions.
