Exosomal communication: a pivotal regulator of bone homeostasis and a potential therapeutic target.

Bone homeostasis encompasses two interrelated aspects: bone remodeling and cartilage metabolism. Disruption of bone homeostasis can lead to the development of metabolic bone diseases such as osteoporosis and osteoarthritis. The maintenance of bone homeostasis is a complex process that does not solely rely on the functions of the bone tissue itself.

While this phenomenon has been primarily studied in organisms with complex nervous systems, it remains unclear whether simpler organisms also possess such capabilities. Here, we studied temporal information processing in , a freshwater planarian flatworm with a primitive nervous system.

Here, we integrated single-cell RNA sequencing, single-cell multiomics, and spatial transcriptomics to define the transcriptional, epigenetic, and spatial basis of cell identity and castration response in the mouse prostate. Leveraging these data along with a meta-analysis of human prostates and prostate cancer, we identified cellular orthologs and key determinants of ADT response and resistance.

- PAX2 is identified as an endometrial tumor suppressor frequently inactivated through a unique epigenetic mechanism, rather than promoter hypermethylation.
- In 80% of endometrial cancers, the loss of PAX2 is linked to transcriptional silencing, which alters chromatin features, contributing to cancer development.
- The research highlights new pathways for understanding endometrial cancer origins, potentially influencing future diagnosis and treatment approaches.
Cochlear outer hair cells (OHCs) transduce sound-induced vibrations of their stereociliary bundles into receptor potentials that drive changes in cell length. While fast, phasic OHC length changes are thought to underlie an amplification process required for sensitive hearing, OHCs also exhibit large tonic length changes. The origins and functional significance of this tonic motility are unclear.
