Matrix metalloproteinase‐9 (MMP9) drives ovarian cancer progression. Using MMP9‐null cells (M9‐KO) created from ovarian cancer cells, we found MMP9 loss did not block Epidermal Growth Factor (EGF)‐driven E‐cadherin dissolution or EMT but delayed and reduced EGF‐driven membrane protrusions. Transient MMP9 re‐expression drove membrane protrusion.

Erythropoietic Activity of Proteolytic Enzymes
SummaryCrystalline papain and crude bromelin preparations stimulate erythropoiesis, whereas other proteolytic enzymes are ineffective. Sialic acid, measured by direct Ehrlich reaction, has been detected in crystalline papain preparations.

Biologic activity in a fragment of recombinant human interferon α [PDF]
To attempt to locate functionally important regions of the interferon (IFN) molecule, recombinant human IFN-α2 was subjected to proteolytic digestion. The bacterial proteinase thermolysin produced two major complementary fragments, HuIFN-α2-(1-110) and ...

Serum Soluble Mediator Signatures of Lupus Nephritis: Histologic Features and Response to Treatment
Objective Lupus nephritis (LN) management remains challenging, and novel noninvasive biomarkers are needed. This study quantified serum soluble mediators in the Accelerating Medicines Partnership (AMP) LN cohort to identify biomarkers of histologic features and treatment response.

Modeling the development of proteolytic phenotypes in multi-species oral biofilms
In chronic periodontitis, subgingival biofilms induce an inflammatory response leading to periodontal tissue destruction which may cause tooth loss. The response includes exudation of fluid (GCF) from the gingival pocket, giving rise to a protein-rich ...

Hsp70 in mitochondrial biogenesis [PDF]
The family of hsp70 (70 kilodalton heat shock protein) molecular chaperones plays an essential and diverse role in cellular physiology, Hsp70 proteins appear to elicit their effects by interacting with polypeptides that present domains which exhibit non ...

β‐Catenin/c‐Myc Axis Modulates Autophagy Response to Different Ammonia Concentrations
Ammonia, detoxified by the liver into urea and glutamine, impacts autophagy differently at varying levels. Low ammonia activates autophagy via c‐Myc and β‐catenin, while high levels suppress it. Using Huh7 cells and Spf‐ash mice, c‐Myc's role in cytoprotective autophagy is revealed, offering insights into hyperammonemia and potential therapeutic ...
