Connexin 26 Functions as a Direct Transcriptional Regulator During the Cochlea Development

Advanced Science, EarlyView.
Connexin26 can not only form intercellular channels that mediate rapid communication on the cell membrane, but also enter the nucleus as a transcription factor to directly regulate the transcription of nuclear genes. In the developing cochlea, Cx26 can control the maturation of the molecular scissor ADAM10 by regulating the transcription of TspanC8 ...

Heterointerface‐Functionalized Photoelectric Response of Metal‐Oxide Schottky Photodiode for Intelligent Fire Detection

Advanced Science, EarlyView.
A heterointerface‐functionalized Schottky photodiode (HF‐SPD) is developed to explore the photoelectric capabilities of low‐temperature oxide semiconductors. Besides the remarkable UV detection capability, the bias‐tunable photo response endows HF‐SPD with the unique wavelength selectivity.

Targeting WTAP/ROR1/WNT5A‐Mediated Crosstalk Between Glioma Stem Cells and Macrophages to Normalize Tumor Vasculature and Enhance Chemotherapy

Advanced Science, EarlyView.
In hypoxic microenvironment, WNT5A is predominantly secreted by tumor‐associated macrophages. Hypoxia‐induced WTAP mediates ROR1 stability by m6A modifications in a HuR‐dependent manner in Glioma stem cells (GSCs). WNT5A activates the WNT pathway via ROR1 binding on GSCs, driving glioma‐derived endothelial cells (GDECs) differentiation.

Charge Injection and Transport in an Isoindigo‐Based Polymer Transistor

Advanced Electronic Materials, EarlyView.
This study presents the charge injection and transport properties of field‐effect transistors based on an isoindigo‐bithiophene donor‐acceptor polymer semiconductor contacted with thiolated self‐assembled monolayer (SAM)‐functionalized electrodes. Temperature‐dependent contact characteristics are measured and simulated.
