Submicrosecond Electric Switching of Large Birefringence in the Isotropic Phase of Ferroelectric Nematics

Advanced Optical Materials, EarlyView.
We demonstrate ultra‐fast and efficient electro‐optical switching using the isotropic phase of ferroelectric nematic liquid crystals. A moderate electric field induces a transition to polar ferroelectric nematic order, producing large field‐induced birefringence with sub‐microsecond switch‐on and switch‐off times. This advance enables new opportunities

Topoisomerase I Inhibition in ETV4‐overexpressed Non‐Small Cell Lung Cancer Promotes Replication and Transcription Mediated R‐Loop Accumulation and DNA Damage

Advanced Science, EarlyView.
The oncogenic ETS factor ETV4 exerts a pleiotropic control over DNA replication both in a transcription‐dependent and ‐independent fashion in NSCLC cells. High‐ETV4 expression leads to R‐loop formation and DNA damage in response to TOP1 inhibition.

METTL14‐Mediated M6A Modification of LINC01094 Induces Glucose Metabolic Reprogramming in Breast Cancer by Recruiting the PKM2/JMJD5 Complex

Advanced Science, EarlyView.
METTL14/IGF2BP2‐mediated m6A modification drives LINC01094 upregulation in BC. Then, LINC01094 interacts with PKM2 monomers to promote their dimerization, while serving as a flexible scaffold to facilitate the assembly of the PKM2/JMJD5 complex, synergistically stabilizing PKM2 dimers and enhancing their nuclear translocation.
