Epidermal development requires ninein for spindle orientation and cortical microtubule organizationIn the epidermis, ninein affects spindle orientation of progenitor cells, as well as cortical microtubule organization, desmosome assembly, and lamellar body secretion in differentiating cells.
The PI3K and MAPK/p38 pathways control stress granule assembly in a hierarchical mannerPI3K and p38 act in a hierarchical manner to enhance mTORC1 activity and stress granule formation; although PI3K is the main driver, the impact of p38 gets apparent as PI3K activity declines.
A dual role for SAMHD1 in regulating HBV cccDNA and RT-dependent particle genesisOur study highlights a dual role for SAMHD1 in regulating hepatitis B virus cccDNA levels and reverse transcriptase–dependent particle genesis.
Location-dependent maintenance of intrinsic susceptibility to mTORC1-driven tumorigenesisPer-cell quantification of mTORC1 signaling activity in neural stem/progenitor cells reveals differential signaling, proliferative, and tumor-forming capability between dorsal and ventral cells within a single niche.
Drug screening with human SMN2 reporter identifies SMN protein stabilizers to correct SMA pathologyThis study has established a versatile human SMN2 reporter line for drug screening and identified a novel strategy of targeting cysteine proteases for rescuing SMA pathological phenotypes.
let-7 coordinates the transition to adulthood through a single primary and four secondary targetsAlthough miRNAs may act through regulation of numerous targets, this study shows that the Caenorhabditis elegans let-7 miRNA promotes the juvenile-to-adult transition through repression of LIN41 alone, thereby activating four LIN41 targets that function in pairs to execute distinct developmental functions.
Functional inhibition of acid sphingomyelinase disrupts infection by intracellular bacterial pathogensMany intracellular pathogens hijack cholesterol. Inhibiting acid sphingomyelinase alters cholesterol traffic to target different intracellular bacteria, signifying a host-directed approach for treating infectious disease.
Sex-regulated gene dosage effect of PPARα on synaptic plasticityDifferences in PPARα expression between males and females affect the regulation of GluA1 expression and synaptic plasticity in mice.
Human DNA polymerase delta is a pentameric holoenzyme with a dimeric p12 subunitThe subunit p12 of human DNA polymerase delta (hPolδ) can dimerize, facilitating its interaction with PCNA and suggesting that hPolδ exists in a pentameric form in the cell.
Dependence on Myb expression is attenuated in myeloid leukaemia with N-terminal CEBPA mutationsWe show that for acute myeloid leukaemias with CEBPA mutations, the dependency of leukaemia growth and differentiation on the Myb transcription factor is related to the combination of N- and C-terminal mutations involved and how this affects overall gene expression.
