Upregulation of circPTPN12 in endometrial epithelial cells (EECs) of fibrotic endometrium sponged miR-21–5 p and resulted in upregulation of its target gene, ΔNp63α, which induced transition of EECs to mesenchymal cells.
Prokaryotes use polycistronic messages for coordinated translation, whereas eukaryotic cells may achieve tunable protein synthesis by packaging monocistronic mRNAs into functional multiplexes via co-transcriptional interallelic coupling and non-canonical histone-H4 functions.
A real-time, stopped-flow method, in combination with protein-induced fluorescence enhancement, Förster resonance energy transfer, and time-resolved fluorescence spectroscopy, reveals a kinetic framework for understanding Dicer as a complex molecular motor.
A combination of animal models reveal how the molecular mechanisms of exosome secretion (RalA/B-dependent) are linked to their cargo content and their function in breast cancer pre-metastatic niche formation.
Human plasma contains protein-protected mRNA fragments, myriad repeat RNAs, and novel intron RNAs, including a family of structured full-length excised introns, some corresponding to mirtron pre-miRNAs and agotrons.
