Nasopharyngeal carcinoma (NPC) is often associated with the infection of Epstein-Barr virus in nasopharynx and is mainly happened in South China and Southeast Asia. Recently, noncoding RNAs have been reported to regulate NPC carcinogenesis. LncRNA OIP5-AS1 participates in tumorigenesis and progression; however, the inherent mechanism of OIP5-AS1-mediated progression of NPC is unclear. In the current study, we aimed to explore the role of OIP5-AS1 in NPC progression. We measured the cell viability, apoptosis, migration, and invasion in NPC cells after OIP5-AS1 modulation. Moreover, we determined whether OIP5-AS1 exerts its oncogenic functions sponging miR-183-5p in NPC. Furthermore, we determined whether glutamate ammonia ligase (GLUL) was a downstream target of miR-183-5p. We found that OIP5-AS1 downregulation inhibited the viability, migration and invasion of NPC targeting miR-183-5p. We also identified that GLUL might be a potential downstream target of miR-183-5p in NPC cells. Mechanistically, OIP5-AS1 promotes cell motility regulating miR-183-5p and GLUL in NPC cells. We concluded that OIP5-AS1 performed its biological functions targeting miR-183-5p and GLUL in NPC cells.

The defining property of eukaryotic cells is the storage of heritable genetic material in a nuclear compartment. For eukaryotic cells to carry out the myriad biochemical processes necessary for their function, macromolecules must be efficiently exchanged between the nucleus and cytoplasm. The nuclear pore complex (NPC) - which is a massive assembly of ~35 different proteins present in multiple copies totalling ~1,000 protein subunits and architecturally conserved across eukaryotes - establishes a size-selective channel for regulated bidirectional transport of folded macromolecules and macromolecular assemblies across the nuclear envelope.

E3 ubiquitin ligases regulate the cellular proteome proteasome-dependent protein degradation; however, there exist limited studies outlining their non-canonical functions. RNA-binding ubiquitin ligases (RBULs) represent a subset of E3 ligases that harbour RNA-binding domains, making them uniquely positioned to function as both RNA-binding proteins and E3 ligases. Our initial microarray screen for E3 ligases from mouse cortical neural progenitor cells identified MEX3B, a known RNA-binding ubiquitin ligase, to be differentially expressed.

The Hippo pathway and its transcription co-activator YAP play a critical role in the regulation of cell proliferation, apoptosis and the control of organ size. In the past several years, YAP has been found to be expressed in various human cancers, however, its expression in Nasopharyngeal Carcinoma (NPC) remains unstudied. In this report, we found that YAP was overexpressed in human NPC tissues, and its expression was also significantly higher in five NPC cell lines when compared with the nasopharyngeal epithelial cell line NP69 (P < 0.

Traumatic Brain Injury (TBI) is a common and debilitating injury, causing long-lasting neurological deficits. Current therapeies for recovery remain inadequate, undersing the urgent need for innovative interventions. In this study, a novel therapeutic approach is introduced that delivers extracellular vesicles (EVs) derived from human-induced pluripotent stem cell-derived neural progenitor cells (hiPSC-NPCs) with a gelatin-based injectable bioorthogonal hydrogel (BIOGEL).
