New #cardiomyocyte research maps temporal alternative splicing regulation during cardiac regulation and uncovers altered splicing events in iPSC-cardiomyocytes, providing insights into the limitations of these models in cardiovascular research. https://ow.ly/kr4550XSzCS
#PDE4DIP is identified as a driver of #LeftVentricularNoncompaction; its overexpression disrupts #cardiomyocyte polarity and energy metabolism, while knockdown restores #ATP and migration, highlighting new therapeutic targets for LVNC.

Another monthly COE meeting funded by the @novo-nordisk.bsky.social was held, highlighting the research done by Carmo-Fonseca and Tom Kirchhausen lab.
The theme for today was to explore the #ASO, synthesized in KJJ’s lab, uptake in #cardiomyocyte cells along with understanding #endosomalescape.
Ayako Takeuchi & Satoshi Matsuoka performed a simulation study on the role of #mitochondria-sarcoplasmic reticulum Ca2+ interaction in #cardiomyocyte energetics during exercise 🏃 🔬

Dr. Robert Zweigerdt from Hannover Medical School joined us for a great conversation about #cardiomyocyte differentiation and heart-forming #organoids!

In an effort to pretend life is normal and we can just talk science, our #journalclub today featured Liz on the lasting epigenomic traces of #obesity; Diana on ML-directed #protein #evolution; and James critiqued #iPSC #cardiomyocyte sheets. A welcome distraction from the prevailing woes about NIH.
