The decision to commit to cell division-the Start transition-in budding yeast is governed by time integration of G1 cyclin-CDK activity by the transcription factor Whi5.
Age-dependent changes in DNA methylation are tightly coupled to the metabolic state, and is partly under genetic regulation, and longer lifespan is associated with lower epigenetic entropy at CpGs that increase in methylation with age.
The first example of an animal where RNA-editing dramatically reshapes the entire proteome demonstrates that editing must be a critical evolutionary and adaptive force.
Mediator, a transcriptional coactivator complex, is essential for transcription but is not a required component of a functional preinitiation complex, indicating that Mediator is not equivalent to a general transcription factor.

The mutational flexibility of the antimalarial target dihydroorotate dehydrogenase thwarts the use of collateral sensitivity as a strategy to suppress the evolution of resistance.
A mitochondrial membrane-bound protein ATAD1 uses conserved structural elements to remove mislocalized membrane proteins from the outer mitochondrial membrane, achieving proper cell organization.

Combining cerebral organoid technology with cryo-correlative microscopy reveals the organization of cytoskeleton, membrane compartments, and protein synthesis machinery contributing to the rapid expansion of developing human axons.

Hypertrophic chondrocytes of the growth plate undergo a process of dedifferentiation to generate marrow associated skeletal stem and progenitor cells (SSPCs), which ultimately re-differentiate into cells of the osteoblast or adipocyte lineages during skeletal development.
