A Branched SNF1‐Related Protein Kinase 2 Signalling Cascade Controls ABA‐Induced Ethylene Production and Regulates Both Fruit Ripening and Reproductive Growth

Plant Biotechnology Journal, Volume 24, Issue 4, Page 2657-2672, April 2026.
ABSTRACT Control of fruit ripening, quality and yield is of major scientific, nutritional and commercial importance. The burst of ethylene (ET) production at the initiation of ripening is the most critical event controlling climacteric (CL) fruit ripening, yet little is known about how it is initiated.

PERFORMANCE EVALUATION OF CASCADE REFRIGERATION SYSTEMS USING DIFFERENT REFRIGERANTS

, 2012
Due to the negative effects of synthetic refrigerants on the environment, natural refrigerants have obtained again interest as alternative refrigerants for di®erent applications because of their zeroODP and negligible GWP.

ATG4B is required for mTORC1‐mediated anabolic activity and is associated with clinical outcomes in non‐small cell lung cancer

FEBS Open Bio, Volume 16, Issue 3, Page 570-583, March 2026.
The relationship between anabolic and catabolic processes governing lung cancer cell growth is nuanced. We show that ATG4B, an autophagy regulator, is elevated in lung cancer and that high ATG4B is associated with worse patient outcomes. Targeting ATG4B in cells reduces growth, protein synthesis, and mTORC1 activity, demonstrating a new relationship ...
