CDC42 Polarity Controls Intestinal Stem Cell Fate
2026-08-27
Zhang et al. show that CDC42-dependent epithelial polarity regulates the intestinal stem cell to transit-amplifying cell transition through a YAP/TAZ–epiregulin–mTOR cascade rather than through canonical Wnt signaling alone. The study links tissue architecture to stem-cell fate and identifies EGFR and mTOR as experimentally tractable points for investigating crypt hyperproliferation.

N1-Methylpseudouridine and Translational Fidelity
2026-08-26
The Cell Reports study examined whether N1-methylpseudouridine, a defining modification in COVID-19 mRNA vaccines, changes ribosomal decoding or produces miscoded proteins. Its complementary translation, RNA duplex, and reverse-transcription assays indicate that the modification largely preserves translational accuracy while avoiding some effects associated with pseudouridine.

FLOT1–FOSL2–EphA2 Axis in Alzheimer’s Neuroinflammation
2026-08-26
The reference study identifies a FLOT1–FOSL2–EphA2 regulatory axis that promotes pro-inflammatory microglial polarization through p38/MAPK signaling in an APP/PS1 model. Its combination of molecular interaction assays, transcriptional validation, pathway perturbation, and behavioral testing links microglial regulation to neuroinflammation and spatial memory.

Digoxin: Na+/K+ ATPase Inhibitor Research Guide
2026-08-25
Digoxin is a cardiac glycoside and Na+/K+ ATPase pump inhibitor that connects ion transport with cardiac contractility modulation. Research also supports cell-specific inhibition of chikungunya virus infection and HIF-1α-associated inflammatory and fibrotic responses, but these findings remain model-dependent.

CDC42 Polarity Controls Intestinal Stem Cell Fate
2026-08-25
Zhang et al. show that CDC42-dependent apical-basal polarity controls the intestinal stem cell-to-transit amplifying cell transition through a YAP/TAZ-Ereg-mTOR pathway that operates independently of canonical Wnt signaling. Genetic and pharmacological rescue experiments position EGFR and mTOR downstream of polarity loss, while Scribble deletion supports a broader role for epithelial polarity in crypt homeostasis.

RBMS1 Loss Enables PD-L1 Blockade in TNBC
2026-08-24
This study identifies the RNA-binding protein RBMS1 as a regulator of immune-cold triple-negative breast cancer and links its loss to reduced PD-L1 stability. Mechanistically, RBMS1 preserves B4GALT1 mRNA and PD-L1 glycosylation, suggesting a tractable route to strengthen T-cell-based therapies.

Intravesical p21 mRNA-LNP Therapy for Bladder Cancer
2026-08-22
The reference study develops a localized mRNA replacement strategy in which lipid nanoparticles deliver CDKN1A/p21 mRNA directly to orthotopic bladder tumors. Its findings connect restored nuclear p21 expression with cell-cycle suppression, DNA-damage signaling, apoptosis, and reduced tumor growth, while highlighting intravesical administration as a way to limit systemic exposure.

N1-Methylpseudo-UTP for Modified RNA Synthesis
2026-08-20
N1-Methyl-Pseudouridine-5'-Triphosphate, also called N1-Methylpseudo-UTP, is a modified uridine triphosphate for in vitro RNA synthesis. Product specifications support its use as a lithium-salt reagent for RNA stability enhancement, while peer-reviewed work shows that N1-methylpseudouridine-modified mRNA can be translated accurately without a detectable increase in miscoded peptides under the tested conditions.
