Loss miRNA maturation in proopiomelanocortin (POMC) neurons causes metabolic dysregulation and favors the differentiation of Pomc progenitors into neuropeptide Y neurons, a developmental process that appears to specifically involve miR-103/107.
A key transcription-factor for osteogenic differentiation, PLZF, acts as a transcriptional activator by binding to active developmental enhancers and facilitates mediator recruitment, but is not involved in enhancer looping.
An integrated landscape framework shows how the coordinated changes in vocal apparatus, muscles, nervous system, and social interaction together influence the trajectory of vocal development.
Evolutionary novelty is promoted by a macroevolutionary pulse of developmental plasticity, but is enhanced by secondary fixation, which permits developmental character release and further morphological exploration.
Unsupervised cluster analysis identified similar groups of children in different cohorts, with distinct developmental patterns of immunorespiratory health, asthma and allergy.
Single-cell analyses of cells infected by Herpes Simplex Virus 1 revealed extreme heterogeneity among infected cells, including the robust activation of developmental gene programs in highly infected cells.
Cuttlefish embryos reveal that cephalopod mollusks evolved specialized arms and tentacles by activating the same genetic circuits that control development of limbs in arthropods and vertebrates.
Analysis of the endogenous function of deeply conserved neuropeptides in sea anemones sheds light on a primitive role of nervous systems in modulating developmental timing.
