SU-101 for the removal of pharmaceutical active compounds by the combination of adsorption/photocatalytic processes

Scientific Reports
Pharmaceutical active compounds (PhACs) are some of the most recalcitrant water pollutants causing undesired environmental and human effects. In absence of adapted decontamination technologies, there is an urgent need to develop efficient and sustainable

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

Molecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Structural evolution and strain generation of derived-Cu catalysts during CO2 electroreduction

Nature Communications, 2022
Copper catalysts derived from oxidized precursors typically exhibit high selectivity for CO2 electroreduction to multicarbon products, yet the influencing factors that control the selectivity need further investigation.

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.

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

Molecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.

Boosting the aqueous-phase production of lactic acid via dual-site activation of carbohydrates

Catalysis Communications, 2023
A series of Zr-based catalysts were prepared using various commercial and cheap organic acids as the coordination agents, and these as-synthesized samples exhibited superior activities to produce lactic acid (LaA) from carbohydrates. Using humic acid (HA)
