Studies of Slc30a10 Deficiency in Mice Reveal That Intestinal Iron Transporters Dmt1 and Ferroportin Transport ManganeseSummary

open access: yesCellular and Molecular Gastroenterology and Hepatology
Background & Aims: SLC11A2 (DMT1) and SLC40A1 (ferroportin) are essential for dietary iron absorption, but their role in manganese transport is debated.

Mineral Deposition From Liquid Precursors Triggered by Complementary Polyelectrolytes

open access: yesAdvanced Functional Materials, EarlyView.
Polyelectrolyte additives can delay or prevent crystal nucleation in supersaturated solutions of insoluble mineral salts such as calcium carbonate. This work reports that adding a second, oppositely‐charged polyelectrolyte leads to immediate mineral crystallization from such metastable solutions.

Molecular Regulatory Mechanisms Drive Emergent Pathogenetic Properties of Neisseria gonorrhoeae

open access: yesMicroorganisms, 2022
Neisseria gonorrhoeae is the causative agent of the sexually transmitted infection (STI) gonorrhea, with an estimated 87 million annual cases worldwide. N. gonorrhoeae predominantly colonizes the male and female genital tract (FGT).

Nanofiber‐Supported Decellularized Matrix Membrane Creates a Biomimetic Biochemical and Biophysical Niche for Intestinal Organoid Epithelium

open access: yesAdvanced Healthcare Materials, EarlyView.
A nanofiber‐supported decellularized extracellular matrix (NaDE) membrane recreates key biochemical and mechanical features of native intestinal tissue. This platform enables the formation of a more physiologically relevant intestinal epithelium, enhancing stem cell maintenance and promoting diverse cell differentiation.

Structural Features Mediating Zinc Binding and Transfer in the AztABCD Zinc Transporter System

open access: yesBiomolecules, 2020
Many bacteria require ATP binding cassette (ABC) transporters for the import of the essential metal zinc from limited environments. These systems rely on a periplasmic or cell-surface solute binding protein (SBP) to bind zinc with high affinity and ...

Rational Design of Organic Chromophores for Simultaneously Trig‐gering Redox Imbalance and Tracking Organelles in Biological Sys‐tems Under Near‐Infrared Light Irradiation

open access: yesAdvanced Healthcare Materials, EarlyView.
TOC represents the synthesis of theory‐guided novel near‐infrared (NIR) light‐absorbing organic photosensitizers (OPS) enabling redox‐induced tumor phototherapy and single‐cell organelle tracking. ABSTRACT The design of organic photosensitizers that operate efficiently in the near‐infrared (NIR) region remains challenging due to the need to balance ...

Cellular transport and homeostasis of essential and nonessential metals [PDF]

open access: yesMetallomics, 2012
Metals can have a number of detrimental or beneficial effects in the cell, but first they must get in. Organisms have evolved transport mechanisms to get metals that are required, or essential into the cell. Nonessential metals often enter the cell through use of the machinery provided for essential metals.
