| Title |
CUT&RUN-seq: Stress increases sperm respiration and motility in mice and men |
| Organism |
Mus musculus |
| Experiment type |
Genome binding/occupancy profiling by high throughput sequencing
|
| Summary |
Cumulative stress and adverse experiences precipitate changes in overall health, disrupting homeostasis and increasing disease. Stress is a known driver of allostatic changes, allowing for cellular adaptation in the face of environmental challenges. However, the molecular mechanisms regulating allostasis and long-term changes in intra- and intercellular signaling important for health are not clear. In males, chronic stress produces lasting changes in epididymal epithelial cell (EEC) intercellular signaling and extracellular vesicle (EV) composition important for sperm maturation. Here we used this system to assess the mechanisms regulating allostasis and the role of EVs to impact downstream target cell physiology and function. We found that prior corticosterone treatment decreased EEC energy requirements and altered mitochondrial ultrastructure, with changes in the cellular set point involving the mitochondrial complex I. CUT&RUN sequencing and gene co-expression network analysis separately identified significant epigenetic and transcriptomic reprogramming important for mitochondrial function. We found this new EEC allostatic state regulated EV intercellular communication with sperm, where EVs isolated from stress EECs increased sperm mitochondrial respiration, ultimately increasing sperm motility. These data support a signaling pathway by which a new cellular allostatic setpoint can be communicated to other cells, affecting their function.

| Overall design |
Immortalized mouse distal caput epididymal epithelial (DC2) cells at monolayer confluency, the media was replaced, and cells were either treated with 1:1000 vehicle (ethanol; resulting in 0.1% ethanol) or 1:1000 corticosterone in ethanol (Cayman Chemical, 16063; 1.4mM, resulting in 500 ng/ml of corticosterone). The media was replaced 72 hours (day 3) and 144 h (day 6) following the treatment. Cells were collected at media changes prior to treatment, immediately following treatment on day 3, after 3 days of recovery on day 6, or after 6 days of recovery on day 9. For cell collection, cells were trypsinized in 0.25% trypsin-EDTA (Gibco), centrifuged at 500xg for 3 min, and frozen at -80°C until further analysis.
