Role of the segment 400-500 in biological activity of Bordetella pertussis adenylate cyclase toxin [PDF]
The adenylate cyclase toxin-hemolysin (CyaA) plays a key role in virulence of the whooping cough agent Bordetella pertussis. It translocates an AC enzyme into cytosol of CD11b+ phagocytes and subverts their bactericidal functions by unregulated ...

Abstract Background Myocyte enhancer factor 2 transcription factors regulate essential transcriptional programs in various cell types. The activity of myocyte enhancer factor 2 factors is modulated through interactions with cofactors, chromatin remodelers, and other regulatory proteins, which are dependent on cell context and physiological state.

SIRT3‐Dependent Actions of Berberine: From Molecular Therapies to Toxicity
This study reveals that berberine's therapeutic versatility in metabolic, cardiovascular, and hepatic disorders stems from its modulation of the mitochondrial protein Sirt3. Understanding this mechanism explains both its broad efficacy and its organ‐specific toxicity, positioning berberine as a promising mitochondrial epigenetic modulator whose ...

Adenylate cyclase toxin-mediated delivery of the S1 subunit of pertussis toxin into mammalian cells [PDF]
The adenylate cyclase toxin (ACT) of Bordetella pertussis internalizes its catalytic domain into target cells. ACT can function as a tool for delivering foreign protein antigen moieties into immune effector cells to induce a cytotoxic T lymphocyte response.

Iron and Other Metal Ions in Human Health and Disease
Iron, copper, zinc, and calcium orchestrate cellular function through distinct yet cooperative mechanisms: redox‐active iron and copper cycle between oxidation states to act as Fenton catalysts and electron carriers in oxidative phosphorylation (OXPHOS); redox‐inert zinc serves as a structural component of zinc‐finger proteins and a catalytic cofactor ...

Cytokine regulation of adenylate cyclase activity in LLC-PK1 cells [PDF]
Cytokine regulation of adenylate cyclase activity in LLC-PK1 cells. Although several cytokines have been demonstrated to exert pleiotropic responses, there is little information on cytokine regulation of renal tubular epithelial cell function.

The adenylate cyclase (CyaA) toxin produced in Bordetella pertussis is the causative agent of whooping cough. CyaA exhibits the remarkable capacity to translocate its N-terminal adenyl cyclase domain (ACD) directly across the plasma membrane into the ...

β‐Caryophyllene is a multifunctional sesquiterpene with significant therapeutic potential. Our findings demonstrate that β‐caryophyllene exerts broad hepatoprotective effects through the activation of cannabinoid type 2 (CB2) receptors. These effects include suppression of oxidative stress–induced injury, attenuation of inflammatory responses ...

Adenylate cyclase activity of ν-ras-k transformed rat epithelial thyroid cells [PDF]
The regulation of adenylate cyclase has been analyzed in normal rat thyroid cells as well as in the same cells transformed by the ν-ras-k oncogene. In both cell types the adenylate cyclase complex consists of the two GTP-binding proteins, Gi and Gs, as ...

Reactive Oxygen Species in Breast Cancer: From Redox Dysregulation to ROS‐Responsive Therapeutics
ABSTRACT Breast cancer is the most frequently diagnosed malignancy among women worldwide, with 2.3 million new cases and approximately 670,000 deaths reported in 2022 alone. Despite advances in therapy, metastasis and acquired drug resistance remain major clinical challenges.
