Article Synopsis
- - The study investigates the role of TCTP (translationally controlled tumor protein) in regulating oncogenic intercellular signaling through extracellular vesicles (EVs), particularly in response to genotoxic stress.
- - Researchers used a Tctp-inducible knockout mouse model and found that TCTP is crucial for triggering apoptosis signaling and promoting malignant growth via small EVs (sEVs).
- - The findings suggest that TCTP enhances tumor development by binding to DDX3 and recruiting RNAs, including miRNAs, to sEVs, and inhibiting TCTP can improve survival rates in tumor-prone mice.
Fluorescent and Electroactive Low-Viscosity Tetrazine-Based Organic Liquids.
ACS Appl Mater Interfaces
August 2016
New fluorescent molecular liquids with a tetrazine core have been prepared. These compounds remain liquid at least down to -60 °C and display very low viscosities (28 mPa.s for liquid 1, 58 mPa.

Reversible and fatigue-resistant optical switching and SHG activity were demonstrated. Interestingly, it was observed that DBSAP nanorods exhibit intermediate photochromic properties compared to solution and solid.

For this purpose, we have developed a simple and convenient protocol involving combination of UV-visible and infra-red absorption spectroscopy. Photochromic cyclization reaction of cis-l,2-dicyano-l,2-bis(2,4,5-trimethyl-3-thieny1)ethene (CMTE) is analyzed to demonstrate the efficiency of the proposed methodology.
