Preventing premature interactions between microtubules and protein-based structures called kinetochores ensures that chromosomes are segregated by meiosis rather than mitosis in reproductive cells.
The nematode worm C. elegans consumes familiar bacterial species more rapidly than it does novel ones, and this preference for familiarity is mediated by a pair of serotonergic neurons.

Efflux of xenobiotic fluoride from microorganisms occurs through a novel family of ion channels with stringent selectivity for fluoride ion and dual-topology molecular architecture.
The Brahma chromatin remodelling complex interacts with the Hippo signalling pathway to regulate the proliferation and differentiation of stem cells in the Drosophila midgut.
Reoxygenation of anoxic cardiac tissue promotes massive endocytosis that is triggered by release of coenzymeA from mitochondria, followed by palmitoylation of membrane proteins, sarcolemma vesiculation, and transfer of sarolemma vesicles to large endosomes and vacuoles.
Mitochondria can trigger massive endocytosis by releasing coenzyme A into the cytoplasm and thereby promoting the addition of fatty acids to surface membrane proteins.
The delayed-onset of asynchronous transmitter release seen in neurons that fire repeatedly is triggered by a different source of calcium from that which triggers synchronous transmitter release.
