Cardiac reprogramming and Gata4 overexpression reduce fibrosis and improve diastolic dysfunction in heart failure with preserved ejection fraction [Visium]

Fibrosis is important pathogenesis in heart failure with preserved ejection fraction (HFpEF). We previously reported that the overexpression of cardiac transcription factors, Mef2c/Gata4/Tbx5/Hand2 (MGTH) could directly reprogram cardiac fibroblasts (CFs) into induced CMs (iCMs) and reduce fibrosis. Here we show that in vivo cardiac reprogramming generated iCMs from resident CFs, improved cardiac function, and reversed fibrosis in HFpEF model using a novel transgenic mouse system. Visium revealed spatial information on changes in gene expression in HFpEF.

Needs pip install lamindb and network access to the Lamin database, which is limited during the alpha. If it fails, use the Client tab.

import lamindb as ln

db = ln.DB("scverse/spatialdata-db")
coll = db.Collection.get(key="geo-gse218759")
coll.ordered_artifacts.to_dataframe()   # the 3 members, ordered

# download every member .zarr to the local cache:
