The successful candidate will use a variety of model systems —including mouse, zebrafish, C. elegans, and yeast at the interface of genetics, cell biology, and biochemistry to tackle fundamental questions in nutrient deficiencies, anemia and genetics. (2/2)

The Hamza Lab is seeking a highly motivated senior scientist to join their research program at the University of Maryland in investigating the molecular and cellular mechanisms of heme/iron homeostasis and its impact on growth and development. Email me directly. (1/2)

Originating as the East Coast Iron Club (ECIC) in New York in 1975, the East-West Iron Club (EWIC) is an annual gathering deeply rooted in the exploration of iron biology and translational research and has now evolved into a nationally recognized event.

A brief history of the Red Cell Club - PubMed A brief history of the Red Cell Club

The Red Cell Club was created in 1958 to foster the exchange of published and unpublished data on all aspects of erythrocyte biology, from developmental erythropoiesis to diagnosing and treating inherited and acquired erythrocyte disorders (pubmed.ncbi.nlm.nih.gov/11358359/)

I will host the 2025 combined meeting of the Red Cell Club and the East -West Iron Club at the University of Maryland School of Medicine, Baltimore,MD from October 27-29, 2025.
Scientific Chairs:
Patrick Gallagher, MD Nationwide Children's Hospital

Metals in Motion: Understanding Labile Metal Pools in Bacteria Metal ions are essential for all life. In microbial cells, potassium (K+) is the most abundant cation and plays a key role in maintaining osmotic balance. Magnesium (Mg2+) is the dominant divalent cation and is required for nucleic acid structure and as an enzyme cofactor. Microbes typically require the transition metals manganese (Mn), iron (Fe), copper (Cu), and zinc (Zn), although the precise set of metal ions needed to sustain life is variable. Intracellular metal pools can be conceptualized as a chemically complex mixture of rapidly exchanging (labile) ions, complemented by those reservoirs that exchange slowly relative to cell metabolism (sequestered). Labile metal pools are buffered by transient interactions with anionic metabolites and macromolecules, with the ribosome playing a major role. Sequestered metal pools include many metalloproteins, cofactors, and storage depots, with some pools redeployed upon metal depletion. Here, I review the size, composition, and dynamics of intracellular metal pools and highlight the major gaps in understanding.

What do we mean by "labile metal pools"?
Their properties depend primarily on the identity of the cation (are are conserved across species).
This review is part of a special issue dedicated to my post-doc mentor Chris Walsh.

Nice review John.

As a Biochemist who does Genetics, I first came across this article in the early 2000s (review.ucsc.edu/spring04/bio...). A good laugh to start your new year courtesy of the Sullivan and Kellogg labs at UCSC, who debated the relative merits of genetics and biochemistry many decades ago. Enjoy!

Calling it a night!

On the beautiful Appalachian Trail for an overnight hike with temps around 20F/-6C. Doesn't get any better.

Very interesting paper, adding lysosomes as an organelle delivering iron to mitochondria to control ferroptosis!
