The imbalance of excitatory/inhibitory neuron differentiation in neurodevelopmental disorders with an NR2F1 point mutation (The Third Replicate)

Project description:Recent studies have revealed an essential role for embryonic cortical development in the pathophysiology of neurodevelopmental disorders, including autism spectrum disorder (ASD). However, the genetic basis and underlying mechanisms remain unclear. Here, we generate mutant human embryonic stem cell lines (Mut hESCs) carrying an NR2F1-R112K mutation that has been identified in a patient with ASD features, and investigate their neurodevelopmental alterations. Mut hESCs overproduce ventral telencephalic neuron progenitors (ventral NPCs) and inhibitory neurons, and underproduce dorsal NPCs and excitatory neurons. These alterations can be mainly attributed to the aberrantly activated Hedgehog signaling pathway. Moreover, the corresponding Nr2f1 point mutant mice display a similar excitatory/inhibitory neuron imbalance and abnormal behaviors. Antagonizing the increased inhibitory synaptic transmission partially alleviates their behavioral deficits. Together, our results suggest that the NR2F1-dependent imbalance of excitatory/inhibitory neuron differentiation caused by the activated Hedgehog pathway is one precursor of neurodevelopmental disorders and may enlighten the therapeutic approaches.

Late recurrence-associated long non-coding RNA NR2F1 antisense 1 (NR2F1-AS1)

Project description:Long non-coding RNA NR2F1 antisense RNA1 (lncRNA NR2F1-AS1) was identified as the main candidate associated to late recurrence in ER-positive breast cancer clinical samples. Gain-of-function of NR2F1-AS1 induced the expression of dormancy-inducers BMP4 and DEC2, and upregulated pluripotency markers NANOG and OCT4. Representative pathways entailed to metastatic events such as HER2/Neu, hypoxia, EMT and inflammatory-response were also found enriched.

Long Non-coding RNA NR2F1-AS1 Induces Breast Cancer Dormancy in Lungs by Regulating NR2F1 and ΔNp63

Project description:We show that the epithelial-like and mesenchymal-like subpopulations of breast cancer stem-like cells (BCSCs) demonstrate different levels dormancy and tumorigenicity in lungs. The long non-coding RNA (lncRNA) molecule NR2F1-AS1 (NAS1) is up-regulated in the dormant BCSC subpopulation, and functionally promotes tumor dissemination but reduces proliferation in lungs. Mechanically, NAS1 promotes internal ribosome entry site (IRES)-mediated NR2F1 translation, leading to inhibition of ΔNp63 transcription by NR2F1. Further, ΔNp63 downregulation results in epithelial-mesenchymal transition, reduced tumorigenicity and enhanced dormancy of cancer cells in lungs.

Knockdown of lncRNA NR2F1-AS1 in gastric cancer cells

Project description:Our data showed that NR2F1-AS1 functions oncogenic roles in gastric cancer (GC), but the underlying molecular mechanism remains largely unknown to date. To explore the function of lncRNA NR2F1-AS1 in gastric cancer, loss-of-function and RNA sequencing studies were performed in SGC7901 cell line. The results showed that depletion of NR2F1-AS1 significantly decreased the expression of VAMP7. Interestingly, VAMP7 was also a target gene of miR-29a-3p. Our data showed that NR2F1-AS1 promotes GC progression through regulating miR-29a/VAMP7 axis.
