Autism and mild epilepsy associated with a de novo missense pathogenic variant in the GTPase effector domain of DNM1

open access: yesAmerican Journal of Medical Genetics Part C: Seminars in Medical Genetics, EarlyView., 2023
Abstract Dynamin 1 is a GTPase protein involved in synaptic vesicle fission, which facilitates the exocytosis of neurotransmitters necessary for normal signaling. Pathogenic variants in the DNM1 gene are associated with intractable epilepsy, often manifested as infantile spasms at onset, developmental delay, and a movement disorder, and are located in ...

On the accumulation of deleterious mutations during range expansions

open access: yes, 2013
We investigate the effect of spatial range expansions on the evolution of fitness when beneficial and deleterious mutations co-segregate. We perform individual-based simulations of a uniform linear habitat and complement them with analytical ...

Igfbp2 Downregulation in PVT‐CeA Glutamatergic Circuits Drives Neonatal Anesthesia‐Induced Fear Memory Deficits

open access: yesAdvanced Science, EarlyView.
Repeated neonatal sevoflurane exposure impairs adolescent fear memory through Igfbp2 downregulation in paraventricular thalamus‐central amygdala glutamatergic projections. Restoring Igfbp2 or activating this circuit rescues memory deficits, neuronal excitability, and spine density, identifying a precise molecular target for preventing anesthesia ...

Co‐Selection of Low Cadmium Accumulation and High Yield During Tomato Improvement

open access: yesAdvanced Science, EarlyView.
This study finds that large‐fruited tomatoes accumulate less cadmium (Cd) compared to wild tomatoes and cherry tomatoes. This is because, during the improvement process of tomato, the low‐Cd allele LCT1A and the large fruit allele fw3.2T are closely linked, leading to a co‐selection event.

BRD4 Signaling Maintains the Differentiated State of β Cells

open access: yesAdvanced Science, EarlyView.
The comprehensive exploration revealed the critical role of BRD4 in β cells. BRD4 plays a fundamental role in maintaining β cell differentiation because both long‐term and acute BRD4 deficiency result in a reduction in insulin secretion and downregulation of differentiation markers.

Engineering Adenine Deaminase TadA for Precise and PAM‐Flexible Point Mutagenesis and Gradient‐Tuning Endogenous Protein Design

open access: yesAdvanced Science, EarlyView.
Base editing enables precise nucleotide substitutions but limited by bystander editing. This study engineers plant base editors by fusing optimized TadA variants with PAM‐flexible SpRY nickase, enabling A‐to‐G, C‐to‐T, and dual‐base conversions in a highly condensed window (≤3 nucleotides). Additionally, TadDBE (TadA Dual‐Base Editor)‐mediated directed
