Adaptive resistance is not responsible for long-term drug resistance in a cellular model of triple negative breast cancer [PDF]

open access: yes, 2022
Resistance to cancer therapeutics represents a leading cause of mortality and is particularly important in cancers, such as triple negative breast cancer, for which no targeted therapy is available, as these are only treated with traditional ...

Desymmetrization of meso-methylenecyclopropanes by a palladium-catalyzed asymmetric ring-opening bis(alkoxycarbonylation) reaction [PDF]

open access: yes, 2014
Desymmetrization of various meso-methylenecyclopropanes was accomplished by a palladium-catalyzed asymmetric ring-opening bis(alkoxycarbonylation) reaction employing a chiral bioxazoline ligand. The reaction proceeded smoothly in the presence of copper(I)

Multi-Omics to Illuminate Signaling Molecules of the Gut Microbiota-Brain Axis [PDF]

open access: yes, 2021
The human gastrointestinal (GI) tract harbors hundreds of trillions of microorganisms, collectively referred to as the gut microbiota. Complex, dynamic, and metabolically active by nature, these commensal microbes carry critical functional roles in ...

Comprehensive metabolomic study of the response of HK-2 cells to hyperglycemic hypoxic diabetic-like milieu [PDF]

open access: yes, 2021
Diabetic nephropathy (DN) is the leading cause of chronic kidney disease. Although hyperglycaemia has been determined as the most important risk factor, hypoxia also plays a relevant role in the development of this disease.

Cross‐Linking Mass Spectrometry of the Antimicrobial Peptides Magainin 2 and PGLa Reveals Heterodimerization in Micellar Medium

open access: yesRapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale In this study, we applied cross‐linking mass spectrometry (XL‐MS) to characterize the oligomeric states of a PGLa/magainin 2 mixture and gain insight into the heterodimerization previously suggested in the literature. Both peptides have shown a synergistic enhancement of activity when tested in antimicrobial assays; however, the ...

Cytosolic Phosphoenoylpyruvate Carboxykinase Deficiency: Clinical, Biochemical, and Genetic Features of Five Non‐Finnish Patients

open access: yesAmerican Journal of Medical Genetics Part A, Volume 200, Issue 6, Page 1192-1203, June 2026.
ABSTRACT Cytosolic phosphoenoylpyruvate carboxykinase (PEPCK‐C) is an essential, rate‐limiting enzyme in the gluconeogenesis pathway. PEPCK‐C deficiency presents with hypoglycaemia, hyperlactataemia and hepatopathy, and was first reported in association with bi‐allelic PCK1 variants in 2014.
