Frontiers in Microbiology, 2020 Campylobacter jejuni is a widespread zoonotic pathogen and the leading bacterial cause of foodborne gastroenteritis in humans. Previous infection studies showed disruption of intercellular contacts, induction of epithelial apoptosis, and immune ...

Yeast caspase 1 suppresses the burst of reactive oxygen species and maintains mitochondrial stability in Saccharomyces cerevisiae [PDF]
arXiv, 2015 Caspases are a family of cysteine proteases that play essential roles during apoptosis, and we presume some of them may also protect the cell from oxidative stress. We found that the absence of yeast caspase 1(Yca1)in Saccharomyces cerevisiae leads to a more intense burst of mitochondrial reactive oxygen species (ROS) In addition, compared to wild type

FEBS Open Bio, EarlyView.The A3 adenosine receptors (A3ARs) are overexpressed in prostate cancer. AR 292 and AR 357, as A3AR antagonists, are capable of blocking proliferation, modulating the expression of drug transporter genes involved in chemoresistance, ferroptosis, and the hypoxia response, and inducing cell death.

Effector Caspases and Leukemia [PDF]
International Journal of Cell Biology, 2011 Caspases, a family of aspartate-specific cysteine proteases, play a major role in apoptosis and a variety of physiological and pathological processes. Fourteen mammalian caspases have been identified and can be divided into two groups: inflammatory caspases and apoptotic caspases.

FEBS Open Bio, EarlyView.Etoposide, a topoisomerase II inhibitor, reduces O‐GlcNAcylation in HepG2 liver cancer cells. Further inhibition of O‐GlcNAc transferase by OSMI‐1 enhanced etoposide‐induced apoptosis, lowering the IC50 for viability and increasing the EC50 for cytotoxicity.

Bistability preserving model reduction in apoptosis [PDF]
arXiv, 2007 Biological systems are typically very complex and need to be reduced before they are amenable to a thorough analysis. Also, they often possess functionally important dynamic features like bistability. In model reduction, it is sometimes more desirable to preserve the dynamic features only than to recover a good quantitative approximation. We present an

FEBS Open Bio, EarlyView.Long non‐coding RNAs (lncRNAs) occupy an abundant fraction of the eukaryotic transcriptome and an emerging area in cancer research. Regulation by lncRNAs is based on their subcellular localization in HNSCC. This cartoon shows the various functions of lncRNAs in HNSCC discussed in this review.

Advanced Functional Materials, EarlyView.The Angiopep‐2 peptide density on polymeric nanoparticles significantly impacts blood–brain barrier (BBB) penetration. This study explores this nuanced relationship using various in vitro models and in vivo assays, revealing that dynamic models better predict BBB penetration.

Caspase Cleavage Is Not for Everyone [PDF]
Cell, 2008 During apoptosis, caspases cleave cellular substrates to break down and package the apoptotic cell for removal. Reporting in Cell, Mahrus et al. (2008) and Dix et al. (2008) use new approaches that identify hundreds of previously unrecognized caspase substrates, many of which appear to produce polypeptide fragments with potentially new functional ...
