Gliomas are the most common primary intracranial tumors and closely related to circadian clock. Due to the high mortality and morbidity of gliomas, exploring novel diagnostic and early prognostic markers is necessary. Circadian clock genes (CCGs) play important roles in regulating the daily oscillation of biological processes and the development of tumor.

Graphene Substrates Promote the Differentiation of Inner Ear Lgr5+ Progenitor Cells Into Hair Cells.

The ideal treatment for sensory hearing loss is to regenerate inner ear hair cells (HCs) through stem cell therapy, thereby restoring the function and structure of the cochlea. Previous studies have found that Lgr5+ supporting cells (SCs) in the inner ear can regenerate HCs, thus being considered inner ear progenitor cells. In addition to traditional biochemical factors, physical factors such as electrical conductivity also play a crucial role in the regulation of stem cell proliferation and differentiation.

Oriented Growth of Neural Stem Cell-Derived Neurons Regulated by Magnetic Nanochains.

Neural stem cell therapy has become a promising cure in the treatment of neurodegenerative disorders. Owing to the anisotropy of the nervous system, the newly derived neurons need not only the functional integrity but also the oriented growth to contact with the partner cells to establish functional connections. So the oriented growth of the newly derived neurons is a key factor in neural stem cell-based nerve regeneration.

Transcriptomic and epigenomic analyses explore the potential role of H3K4me3 in neomycin-induced cochlear Lgr5+ progenitor cell regeneration of hair cells.

Currently, adult cochlear hair cells (HCs) lack the capacity to regenerate, particularly the hearing damage caused by the HC damage are hard to recover. Remarkably, Lgr5+ inner ear progenitor cells can be activated to proliferate and regenerate hair cells (HCs) in response to injury, but the epigenetic regulatory roles in HC regeneration from Lgr5+ progenitor cells remain unresolved to date. We here investigate the possible roles of H3K4me3 modification in Lgr5+ progenitor cell proliferation and HC regeneration, and identify these differentially expressed genes associated with different binding regions between untreated Lgr5+ progenitor cells (ULPs) and neomycin-treated Lgr5+ progenitor cells (NLPs).
