COMP–PMEPA1 axis promotes epithelial‐to‐mesenchymal transition in breast cancer cells
Molecular Oncology, EarlyView.This study reveals that cartilage oligomeric matrix protein (COMP) promotes epithelial‐to‐mesenchymal transition (EMT) in breast cancer. We identify PMEPA1 (protein TMEPAI) as a novel COMP‐binding partner that mediates EMT via binding to the TSP domains of COMP, establishing the COMP–PMEPA1 axis as a key EMT driver in breast cancer.

Surface Enhanced Raman Scattering (SERS): From Fundamental Mechanism to Bio-Analytics Tools [PDF]
Nano Biomedicine and Engineering, 2016 This review discusses the surface-enhanced Raman scattering (SERS) with efficiencies enhanced by as much as 1014-1015 fold as well as a SERS cross section on the order of 10-17-10-16 cm2/molecule. Despite the existing controversy on the origin of the enhancement, SERS effect offers new opportunities for spectroscopic detection of single molecules near ...

FEBS Open Bio, EarlyView.Enzymes of the 2‐hydroxyacyl‐CoA lyase group catalyze the condensation of formyl‐CoA with aldehydes or ketones. Thus, by structural adaptation of active sites, practically any pharmaceutically and industrially important 2‐hydroxyacid could be biotechnologically synthesized. Combining crystal structure analysis, active site mutations and kinetic assays,

El carisma de un joven profesor inconformista: la fuerza y la magia de Ser y tiempo
Differenz, 2014 Todavía hoy en día, Ser y tiempo sigue siendo un título mágico, compuesto de dos palabras intrigantes que, en su compleja sencillez, intenta repensar la pregunta fundamental de la historia de la filosofía: la pregunta por el ser.
