💡 Key insight: Preserving PIP3 signaling through PTEN inhibition protects against cardiac dysfunction and fibrosis, highlighting a potential therapeutic opportunity.

But this adaptation proves insufficient. Chronic angiotensin II still drives hypertrophy, t-tubule disruption, fibrosis, and diastolic dysfunction.

The researchers found widespread phosphoinositide imbalance and internalization of L-type CaV1.2 calcium channels from t-tubules into endosomal compartments. Yet remarkably, calcium currents are preserved through compensatory PKA and CaMKII signaling.

Phosphoinositide Depletion and Compensatory Phospho-Signaling in Angiotensin II-Induced Heart Disease: Protection Through PTEN Inhibition | Circulation Research BACKGROUND: Contractile dysfunction, hypertrophy, and cell death during heart failure are linked to altered Ca2+ handling and elevated levels of the hormone AngII (angiotensin II), which signals throu...

Compelling new study by @maartjewesthoff.bsky.social, Taylor Voelker, @roseedixon.bsky.social et al. This latest work in Circulation Research explores what happens when angiotensin II signaling becomes chronic. www.ahajournals.org/doi/10.1161/...

This new @pnas.org paper by Yuhua Tian from #PMB Zheng Lab, et al, uncovers TRPM4 as the hub to four major signaling systems. The study reveals how PIP₂ “locks/unlocks” channel activity, helping explain organ-specific diseases from TRPM4 mutations. www.pnas.org/doi/10.1073/...
