    NPAS1-ARNT and NPAS3-ARNT crystal structures implicate the bHLH-PAS family as multi-ligand binding transcription factors

    Dalei Wu et al.
    Detailed structural analysis of NPAS1-ARNT and NPAS3-ARNT complexes, and further comparisons with other bHLH-PAS protein structures, show that this family of mammalian transcription factors have distinct ligand-binding pockets within their molecular architectures.

    Nuclear receptor Ftz-f1 promotes follicle maturation and ovulation partly via bHLH/PAS transcription factor Sim

    Elizabeth M Knapp et al.
    Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.

    Repression by PRDM13 is critical for generating precision in neuronal identity

    Bishakha Mona et al.
    PRDM13, a transcriptional repressor, antagonizes activity of basic-helix-loop-helix transcriptional activators and protects the developing spinal cord from aberrant expression of ventral-restricted cell-type regulators to generate the correct composition of neurons in the dorsal spinal cord.

    E proteins sharpen neurogenesis by modulating proneural bHLH transcription factors’ activity in an E-box-dependent manner

    Gwenvael Le Dréau et al.
    Rather than acting as passive and neutral co-factors for proneural proteins, E proteins play an active role in modulating the way the distinct proneural proteins instruct neurogenesis.

    Insulin-like peptides and the mTOR-TFEB pathway protect Caenorhabditis elegans hermaphrodites from mating-induced death

    Cheng Shi et al.
    Hermaphroditic Caenorhabditis elegans slow the onset of mating-induced death through self-sperm-regulated insulin-like gene expression, which regulates the activity of the IIS/FOXO pathway, mTOR signaling, and the TFEB/HLH-30 transcription factor.

    BMP and FGF signaling interact to pattern mesoderm by controlling basic helix-loop-helix transcription factor activity

    Richard H Row et al.
    Interplay between FGF-induced bHLH transcription factors and BMP-induced bHLH inhibitory id genes govern mesodermal cell fate choice along the mediolateral axis in both zebrafish and mouse.

    Negative regulation of conserved RSL class I bHLH transcription factors evolved independently among land plants

    Suvi Honkanen et al.
    An ancient and conserved genetic mechanism for cell differentiation is under distinct negative regulation in different lineages of land plants.

    Olig3 regulates early cerebellar development

    Elijah D Lowenstein et al.
    The transcription factor Olig3 safeguards the correct specification of early born cerebellar neuron derivatives and curtails an inhibitory interneuron differentiation program.

    NHR-49/PPAR-α and HLH-30/TFEB cooperate for C. elegans host defense via a flavin-containing monooxygenase

    Khursheed A Wani et al.
    Genetic and molecular characterization showed that evolutionarily conserved flavin-containing monooxygenase (FMO-2) plays an important role in host defense in Caenorhabditis elegans, and its induction is dependent on conserved transcription factors, TFEB and PPAR-α.

    A feedback loop governs the relationship between lipid metabolism and longevity

    Nicole K Littlejohn et al.
    The dual control of adiposity and longevity emerges from a latent intestinal feedback loop which simultaneously augments fat loss and shields lifespan from the deleterious effects of continuous fat oxidation.
