A nucleotide‐independent, pan‐RAS‐targeted DARPin elicits anti‐tumor activity in a multimodal manner

Molecular Oncology, EarlyView.
We report a Designed Ankyrin Repeat Protein that binds and inhibits RAS proteins, which serve as central cell signaling hubs and are essential for the progression of many cancers. Its unique feature is that it does not discriminate between different RAS isoforms or mutations and is capable of binding to RAS in both its active (GTP‐bound) and inactive ...

Chimeric diphtheria toxin–CCL8 cytotoxic peptide for breast cancer management

Molecular Oncology, EarlyView.
DTCCL8 is a recombinant fusion toxin that targets cancer cells expressing chemokine receptors. By combining diphtheria toxin with CCL8, DTCCL8 binds to multiple receptors on tumor cells and induces selective cytotoxicity. This strategy enables receptor‐mediated targeting of cancer and may support the development of chemokine‐guided therapeutics ...

Toxins in Fermented Foods: Prevalence and Preventions—A Mini Review

Toxins, 2018
Fermented foods (FF) are widely consumed around the world, and FF are one of the prime sources of toxins and pathogenic microbes that are associated with several foodborne outbreaks.

Gut microbiota diversity is prognostic in metastatic hormone receptor‐positive breast cancer patients receiving chemotherapy and immunotherapy

Molecular Oncology, EarlyView.
In this exploratory study, we investigated the relationship between the gut microbiota and outcome in patients with metastatic hormone receptor‐positive breast cancer, treated in a randomized clinical trial with chemotherapy alone or chemotherapy in combination with immune checkpoint blockade.

Bacterial phospholipases C with dual activity: phosphatidylcholinesterase and sphingomyelinase

FEBS Open Bio, 2021
Bacterial phospholipases and sphingomyelinases are lipolytic esterases that are structurally and evolutionarily heterogeneous. These enzymes play crucial roles as virulence factors in several human and animal infectious diseases.

Blocking the voltage‐gated sodium channel hNav1.5 as a novel pH‐dependent mechanism of action for tamoxifen

FEBS Open Bio, EarlyView.
Patch‐clamp recordings revealed that tamoxifen inhibits voltage‐gated sodium channels, especially under acidic conditions, both common in metastatic cancer cells. These effects may explain certain antitumor properties of tamoxifen, highlighting a novel mechanism of action beyond its known endocrine effects.

The Glucocorticoid Receptor: A Revisited Target for Toxins

Toxins, 2010
The hypothalamic-pituitary-adrenal (HPA) axis activation and glucocorticoid responses are critical for survival from a number of bacterial, viral and toxic insults, demonstrated by the fact that removal of the HPA axis or GR blockade enhances mortality ...

Structures of distant diphtheria toxin homologs reveal functional determinants of an evolutionarily conserved toxin scaffold

Communications Biology, 2022
Toxic proteins are responsible for the disease symptoms accompanying bacterial infections. Sugiman-Marangos et al. report crystal structures of two diphtheria toxin homologs, therefore providing structural insights into this family of toxins and the ...

Cholesterol and the activity of bacterial toxins [PDF]

FEMS Microbiology Letters, 2004
Cholesterol may affect the activity of microbial toxins in a direct, specific way, or it may exert indirect effects because of its role in membrane fluidity, membrane line tension, and in the stabilization of rafts in the cytoplasmic membrane. The thiol-activated toxins of gram-positive bacteria, and the cytolysin of Vibrio cholerae are presented as ...

LYSOSOMAL DISRUPTION BY BACTERIAL TOXINS [PDF]

Journal of Bacteriology, 1964
Bernheimer, Alan W. (New York University School of Medicine, New York), and Lois L. Schwartz . Lysosomal disruption by bacterial toxins. J. Bacteriol. 87: 1100–1104. 1964.—Seventeen bacterial toxins were examined for capacity (i) to disrupt rabbit leukocyte lysosomes as indicated ...
