Targeting human apurinic/apyrimidinic endonuclease 1 (APE1) in phosphatase and tensin homolog (PTEN) deficient melanoma cells for personalized therapy [PDF]

, 2014
Phosphatase and tensin homolog (PTEN) loss is associated with genomic instability. APE1 is a key player in DNA base excision repair (BER) and an emerging drug target in cancer.

Understanding how enzymes work: the journey to ensemble–function studies

The FEBS Journal, EarlyView.
For decades, structure–function has dominated biochemistry. Structures are highly valuable, yet more is needed to achieve a quantitative understanding of biomolecular function, because function emerges from an ensemble of states, rather than a static structure. We describe an ensemble–function framework applied to quantitatively dissect serine protease

1H NMR metabolomics and lipidomics analysis of neutrophils reveals biomarkers of ageing, inflammageing and frailty

The FEBS Journal, EarlyView.
Using 1H NMR metabolomics, we measured polar and lipid metabolites from human blood neutrophils from people with frailty (n = 31, mean age 84Y), people with rheumatoid arthritis (n = 16, mean age 55Y), robust older (n = 24, mean age 66Y) and healthy younger people (n = 21, mean age 22Y).

Direct Synthesis of C-Substituted [RC(O)CH₂-CB₁₁H₁₁]⁻ Carborate Anions

Inorganics
A new synthetic method for the synthesis of C-substituted [RC(O)CH2-CB11H11]− carborate anions has been developed. The reaction of [closo-B11H11]2− with terminal alkynes in the presence of a copper catalyst leads to insertion into the boron cluster, and ...

Towards an integrated molecular understanding of plant hormones

Journal of Integrative Plant Biology, EarlyView.
This review offers a comprehensive overview of the nine plant hormones, delving into their biosynthesis, transport, signaling and crosstalk mechanisms. Because the complexity of plant hormonal control goes beyond these core elements, additional specific features are discussed. Lastly, this review highlights how fundamental insights drive hormonal‐based

Synthesis and crystal structure of N-phenyl-2-(phenylsulfanyl)acetamide

Acta Crystallographica Section E: Crystallographic Communications
N-Phenyl-2-(phenylsulfanyl)acetamide, C14H13NOS, was synthesized and structurally characterized. In the crystal, N—H...O hydrogen bonding leads to the formation of chains of molecules along the [100] direction.
