The Link between Oxygen and Basement Membranes.

Published: January 2025

Epithelial tissues and the basement membranes they sit on did not appear for billions of years. Their appearance was delayed most likely by a lack of oxygen, which is required for collagen synthesis, and which only began to build up following the Great Oxygenation Event ~ 2.4 billion years ago. Both the oxygenation of Earth and the multiple roles of collagen require regulation by electrical forces.

Background The accurate diagnosis of intraductal carcinoma of the prostate (IDC-P) is occasionally challenging due to the similarity in pathological morphology between IDC-P and high-grade prostatic intraepithelial neoplasia (HGPIN). In this report, we reviewed the pathology of cases previously diagnosed as HGPIN to search for IDC-P cases effectively. In addition, we examined whether those cases had genetic abnormalities.

The endoplasmic reticulum (ER) is a vital organelle responsible for protein quality control, including the folding, modification, and transport of proteins. When misfolded or unfolded proteins accumulate in the ER, it triggers endoplasmic reticulum stress (ERS) and activates the unfolded protein response (UPR) to restore ER homeostasis. However, prolonged or excessive ERS can lead to apoptosis.

Epithelia Are Scaffolds for Electricity-Dependent Molecular Interactions.

Rev Physiol Biochem Pharmacol

January 2025

Institute of Medical Sciences, University of Aberdeen, Aberdeen, Scotland, UK.

Once multicellularity was thriving, a key development involved the emergence of epithelial layers that separated "inside" from "outside". Most epithelia then generate their own transepithelial electrical signals. So electrical forces were instrumental in the development of epithelial tissues, which themselves generate further electrical signals.

Implantable Microneedles Loaded with Nanoparticles Surface Engineered for Efficient Eradication of Triple-Negative Breast Cancer Stem Cells.

Eliminating cancer stem cells (CSCs) is essential for the effective treatment of triple-negative breast cancer (TNBC). This study synthesized Au@cerium-zinc composite core@shell nanoparticles (Au@Zn/CeO) that were subsequently conjugated with () to create the engineered bacterium AZCE, which was then combined with microneedle carriers and freeze-dried to obtain AZCE-MN. Upon implantation into TNBC tumors, the inherent properties of facilitate AZCE to penetrate the extracellular matrix and break through the basement membrane, enabling effective delivery of AZC to CSCs-enriched regions deep within the tumor.
