Hydrostatic pressure activates HIF‐1α via β‐catenin to promote stemness in breast cancer cells
FEBS Open Bio, EarlyView.To mimic the elevated intestinal fluid pressure in breast cancers, we loaded human breast cancer cells (MCF‐7, MDA‐MB‐453, and BT‐474) to 50 mmHg hydrostatic pressure. Hydrostatic pressure exposure upregulated HIF‐1α and induced stemness in MCF‐7 and BT‐474 cells.

Abilities of peroxidases to catalyse peroxidase-oxidase oxidation of thiols [PDF]
Biochemical Journal, 1988 The abilities of various peroxidases to catalyse the peroxidase-oxidase oxidation of seven aminothiols were studied. Cysteamine and cysteine esters were found to be peroxidase-oxidase substrates for eosinophil peroxidase and myeloperoxidase, whereas other thiols tested were inactive or poorly active with these peroxidases.

Aquaporin‐3 and aquaporin‐5 impact the development of pancreatic ductal adenocarcinoma spheroids
FEBS Open Bio, EarlyView.Schematic representation of the role of aquaporin‐3 (AQP3) and aquaporin‐5 (AQP5) in pancreatic ductal adenocarcinoma (PDAC). Both proteins are upregulated in PDAC and are associated with tumor progression and metastatic potential. Silencing AQP3 or AQP5 in PDAC spheroids results in decreased diameter, area, and overall growth, underscoring their key ...

Activation of macrophages by peroxidases
, 1986 The role of peroxidase in biological systems is not well understood. The specific aims of the present study were to determine (a) if peroxidases are able to stimulate the production of superoxide by macrophages; (b) if peroxidases are able to activate ...

The Acari Hypothesis, V: deciphering allergenicity
Frontiers in AllergyThe Acari Hypothesis posits that acarians, i.e., mites and ticks, are operative agents of allergy. It derived from observations that allergens are molecular elements of acarians or acarian foodstuffs.
