Gm26550 Modulates Learning and Memory by Increasing IGF1 mRNA Expression and Stability in Nrf2−/− Mice

Advanced Science, EarlyView.
The present study shows that Nrf2 directly binds to the Gm26550 promoter, thereby activating Gm26550 transcription and increasing its expression. Mechanistically, Gm26550 promotes IGF1 expression by functionally antagonizing miR‐26a‐5p‐mediated repression and sequestering the RBP KHSRP, thereby enhancing hippocampal neuronal synaptic plasticity and ...

Low‐Intensity Focused Ultrasound Enables Temporal Modulation of Human Midbrain Organoid Differentiation

Advanced Science, EarlyView.
In this study, we demonstrate that low‐intensity ultrasound stimulation enables temporal modulation of midbrain organoid differentiation using a modular multi‐well stimulation platform. In particular, we show that ultrasound promotes the proliferation of dopaminergic progenitor cells.
