Metarhizium anisopliae Mitigates the Phytotoxicity of Lead and Nanoplastics on Rice by Modifying Physiological, Transcriptomic, Metabolomic Activities, and Soil Microbiome

Advanced Science, EarlyView.
Metarhizium anisopliae alleviates the phytotoxic effects of polyethylene nanoplastics (NP) and lead (Pb) in rice by decreasing Pb uptake, restoring antioxidant and hormonal equilibrium, and promoting growth. Additionally, the fungus modifies the rhizosphere microbiota, enhancing both contaminant tolerance and plant growth, thereby effectively ...

Extreme Kinetic Stability and RNase Resistance of Human Telomerase RNA G‐Quadruplexes Overcome by DHX36 Helicase

Advanced Science, EarlyView.
The RNA G‐quadruplexes formed at the 5'‐end of the RNA component of human telomerase possess extreme slow unfolding rate, rendering them resistant to nuclease degradation. The helicase DHX36 overcame this kinetic barrier and significantly reduced the folded fraction.

Molecular characterization of the A52 murine hepatocellular carcinoma cell line

Animal Models and Experimental Medicine, EarlyView.
Hepatocellular carcinoma (HCC) is a poor outcome cancer with limited therapeutic choices. To advance therapeutic development we genetically characterized the A52 murine HCC cell line. We noted genetic changes that match a subset of human HCC and this offers the opportunity to test novel targeted therapies in syngeneic mice.

The crystal structure of 1-(2-iodobenzoyl)-4-(pyrimidin-2-yl)piperazine: a three-dimensional hydrogen-bonded framework, augmented by π–π stacking interactions and I...N halogen bonds

Acta Crystallographica Section E: Crystallographic Communications, 2019
In 1-(2-iodobenzoyl)-4-(pyrimidin-2-yl)piperazine, C15H15IN4O, the central piperazine ring adopts an almost perfect chair conformation with the pyrimidine substituent in an equatorial site.

DNA Flap‐Mediated Control of Transcription for Programmable RNA Synthesis

Angewandte Chemie International Edition, EarlyView.
Pyrimidine‐rich ssDNA flaps on the T7 promoter inhibit T7 RNA polymerase (T7RP) transcription. Leveraging this pyrimidine bias, we developed DNAzyme‐ and MNAzyme‐mediated flap promoter induced transcription control (D‐FIT and M‐FIT) systems. These platforms enable regulated transcription and sequence‐specific detection, highlighting the programmable ...
