For therapeutic hypoxia, small molecule can mimic mountain trip

Feb. 28, 2025
By Anette Breindl
Too much of a good thing, it turns out, is a concept that applies to oxygen. And researchers at the University of California at San Francisco are working on a small molecule, Hypoxystat, that can lower tissue oxygen levels and prevent damage when oxygen levels are too high. When administered to mice with the rare mitochondrial disorder Leigh syndrome, the molecule more than tripled their average lifespan.

‘Remarkable’ progress in cystic fibrosis means more work needed

Feb. 27, 2025
By Nuala Moran
The map of cystic fibrosis (CF) research is being redrawn in the U.K. as improvements in treatment, and in particular the introduction of CF modulator drugs, mean people with the rare inherited disease are living much longer.

Insights into extracellular matrix are metastasis map

Feb. 24, 2025
By Nuala Moran
New research has uncovered a complex interplay between extracellular matrix (ECM) structure and the transcriptional responses of cancer cells, showing how they alter their gene expression to ‘escape’ from ECM.

Eliminating redundancies opens up possibilities for protein engineering

Feb. 24, 2025
By Anette Breindl
Researchers have altered the genetic code in a strain of Escherichia coli, reducing the number of stop codons from three to one and assigning the freed-up stop codons to nonstandard amino acids. They reported on the recoded bacterium, which they named OCHRE, in Nature on Feb. 5, 2025.

GUK1 is metabolic gate in ALK-driven lung cancer

Feb. 21, 2025
By Xavier Bofill Bruna
Using ALK+ lung cancer patient-derived cell lines, researchers have performed phosphoproteomic screening and identified guanylate kinase 1 (GUK1) as a TKI sensitive metabolic molecule in ALK-driven lung cancer.

By Nuala Moran
New research has uncovered a complex interplay between extracellular matrix (ECM) structure and the transcriptional responses of cancer cells, showing how they alter their gene expression to ‘escape’ from ECM. The findings will make it easier to identify tumors that are likely to metastasize at an early stage.
