Recurrent miscarriage (RM) is a reproductive disorder affecting couples worldwide. The underlying molecular mechanisms remain elusive, even though emerging evidence has implicated endoplasmic reticulum stress (ERS). We investigated RM- and ERS-related genes to develop a diagnostic model that can enhance predictive ability.

Article Synopsis
- Impaired calcium (Ca) handling in heart cells is a key feature of heart failure (HF), leading to issues like weakened heart contractions and irregular heartbeats.
- The study used transgenic mice with a mutation affecting a calcium regulator (phospholamban) to understand how defects in calcium cycling contribute to HF, noting that these mice experience severe and fast-progressing heart failure.
- Early treatment aimed at correcting calcium cycling using Raf kinase inhibitor protein (RKIP) was found to delay heart cell damage and improve overall health of the mice, indicating that addressing Ca dynamics early on could be crucial for preventing further complications in heart failure.
