Respectful Destruction

open access: yesVoices in Bioethics, 2014
Cryogenically frozen embryos present a major problem for virtually all fertility centers across the globe. As procedures for IVF, including egg retrieval and Inter-cytoplasmic-sperm-insemination (ICSI), have become more precise, predictable, and promising, the production of excess viable embryos now leaves couples with the decision to freeze or discard

Structural biology of ferritin nanocages

open access: yesFEBS Letters, EarlyView.
Ferritin is a conserved iron‐storage protein that sequesters iron as a ferric mineral core within a nanocage, protecting cells from oxidative damage and maintaining iron homeostasis. This review discusses ferritin biology, structure, and function, and highlights recent cryo‐EM studies revealing mechanisms of ferritinophagy, cellular iron uptake, and ...

Survivin and Aurora Kinase A control cell fate decisions during mitosis

open access: yesMolecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.
