Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

FEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Security Enhancement and Privacy Protection for Biometric Systems [PDF]

, 2021
Biometric recognition systems are part of our daily life. They enable a user-convenient authentication alternative to passwords or tokens as well as high security identity assessment for law enforcement and border control. However, with a rising usage in general, fraudulent use increases as well.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Dimethyl fumarate combined with cisplatin at subcytotoxic doses sensitizes cervical cancer toward ferroptosis and apoptosis through GSH restriction and p53 (re)activation

Molecular Oncology, EarlyView.
Dimethyl fumarate (DMF) reduces growth of HPV‐positive cervical cancer spheroids and induces ferroptosis in cervical cancer cells via blocking SLC7A11/Glutathione (GSH) axis. Combination of subcytotoxic doses of DMF and cisplatin (CDDP) further suppresses spheroid growth and drives cell death in 2D culture models.

Highly Efficient Photo-Induced Cathodic Protection of 403SS by the All-Solid-State Z-Scheme ZnS-CdS-Ag@TiO2 Nanoheterojunctions

International Journal of Electrochemical Science, 2019
An all-solid-state Z-scheme ZnS-CdS-Ag@TiO2 nanoheterojunction was successfully fabricated to reduce the recombination rate of photogenerated charge carriers and enhance the photocathodic protection efficiency for 403 stainless steel (SS).

Network divergence analysis identifies adaptive gene modules and two orthogonal vulnerability axes in pancreatic cancer

Molecular Oncology, EarlyView.
Tumors contain diverse cellular states whose behavior is shaped by context‐dependent gene coordination. By comparing gene–gene relationships across biological contexts, we identify adaptive transcriptional modules that reorganize into distinct vulnerability axes.
