Semen Quality in Relation to Semen Preservation

Journal of Dairy Science, 1983
A goal of research in laboratory evaluation of semen has been ultimately to predict the fertility achievable with use of that semen. This would permit evaluation of the male and ejaculate. For artificial insemination, semen viability becomes a measure of man's interaction with that semen in an effort to preserve its functional life. Man's efficiency in

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation

FEBS Letters, EarlyView.
Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

Structural biology of ferritin nanocages

FEBS 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 ...
