Neural stem cells (NSCs) are a class of self-renewing, multipotent and undifferentiated progenitor cells that retain the capacity to both glial and neuronal lineages. MicroRNAs (miRNAs) are small non-coding RNAs that play an important role in stem cell fate determination and self-renewal. Our previous RNA-seq data indicated that the expression of miR-6216 was decreased in denervated hippocampal exosomes compared with normal. However, whether miR-6216 participates in regulating NSC function remains to be elucidated. In this study, we demonstrated that miR-6216 negatively regulates RAB6B expression. Forced overexpression of miR-6216 inhibited NSC proliferation, and overexpression of RAB6B promoted NSC proliferation. These findings suggest that miR-6216 played an important role in regulating NSC proliferation via targeting RAB6B, and improve the understanding of the miRNA-mRNA regulatory network that affects NSC proliferation.

Background: The hippocampus is associated with mood disorders, and the activation of quiescent neurogenesis has been linked to anxiolytic effects. Near-infrared (NIR) light has shown potential to improve learning and memory in human and animal models. Despite the vast amount of information regarding the effect of visible light, there is a significant gap in our understanding regarding the response of neural stem cells (NSCs) to NIR stimulation, particularly in anxiety-like behavior.

Dysregulated pH is now recognised as a hallmark of cancer. Recent evidence has revealed that the endosomal pH regulator Na/H exchanger NHE9 is upregulated in colorectal cancer to impose a pseudo-starvation state associated with invasion, highlighting an underexplored mechanistic link between adaptive endosomal reprogramming and malignant transformation. In this study, we use a model that quantitatively captures the dynamics of the core regulatory network governing epithelial mesenchymal plasticity.

Mitotic bookmarking has been posited as an important strategy for cells to faithfully propagate their fate memory through cell generations. However, the physiological significance and regulatory mechanisms of mitotic bookmarking in neural development remain unexplored. Here, we identified TATA-binding protein (TBP) as a crucial mitotic bookmarker for preserving the fate memory of Drosophila neural stem cells (NSCs).

Article Synopsis
  • A study on 325 pulmonary arterial hypertension (PAH) patients found mutations in 23% using a specific gene panel targeting 18 known PAH genes.
  • Additional sequencing identified two variants in the SMAD5 gene, which were further characterized through various functional tests, confirming their expression and effects on cell behavior.
  • One variant was linked to a familial history of PAH and resulted in increased cell viability, while the other variant, associated with congenital heart disease, led to reduced cell viability due to increased apoptosis; both were deemed likely pathogenic and indicate SMAD5 as a potential new PAH gene for diagnostic testing.
