Cells transit through a quiescent-like state to convert to neurons at high rates Published: November, 2024 Abstract:
While transcription factors (TFs) provide essential cues for directing and redirecting cell fate, TFs alone are insufficient to drive cells to adopt alternative fates. Rather, transcription factors rely on receptive cell states to induce novel ide... Read more »
Multiplex, single-cell CRISPRa screening for cell type specific regulatory elements Published: September, 2024 Abstract:
CRISPR-based gene activation (CRISPRa) is a strategy for upregulating gene expression by targeting promoters or enhancers in a tissue/cell-type specific manner. Here, we describe an experimental framework that combines highly multiplexed perturbat... Read more »
Precision and efficacy of RNA-guided DNA integration in high-expressing muscle loci Published: September, 2024 Abstract:
Gene replacement therapies primarily rely on adeno-associated virus (AAV) vectors for transgene expression. However, episomal expression can decline over time due to vector loss or epigenetic silencing. CRISPR-based integration methods offer promi... Read more »
Rhabdomyosarcoma fusion oncoprotein initially pioneers a neural signature in vivo Published: July, 2024 Abstract:
Fusion-positive rhabdomyosarcoma is an aggressive pediatric cancer molecularly characterized by arrested myogenesis. The defining genetic driver, PAX3::FOXO1, functions as a chimeric gain-of-function transcription factor. An incomplete understandi... Read more »
CRISPR screen decodes SWI/SNF chromatin remodeling complex assembly Published: June, 2024 Abstract:
The SWI/SNF (or BAF) complex is an essential chromatin remodeler that regulates DNA accessibility at developmental genes and enhancers. SWI/SNF subunits are among the most frequently mutated genes in cancer and neurodevelopmental disorders. These ... Read more »
Clock-dependent chromatin accessibility rhythms regulate circadian transcription Published: May, 2024 Abstract:
Chromatin organization plays a crucial role in gene regulation by controlling the accessibility of DNA to transcription machinery. While significant progress has been made in understanding the regulatory role of clock proteins in circadian rhythms... Read more »
Cellular reprogramming in vivo initiated by SOX4 pioneer factor activity Published: February, 2024 Abstract:
Tissue damage elicits cell fate switching through a process called metaplasia, but how the starting cell fate is silenced and the new cell fate is activated has not been investigated in animals. In cell culture, pioneer transcription factors media... Read more »
The ncBAF complex regulates transcription in AML through H3K27ac sensing by BRD9 Published: December, 2023 Abstract:
The non-canonical BAF complex (ncBAF) subunit BRD9 is essential for acute myeloid leukemia (AML) cell viability but has an unclear role in leukemogenesis. Because BRD9 is required for ncBAF complex assembly through its DUF3512 domain, precise brom... Read more »
High-capacity sample multiplexing for single cell chromatin accessibility profiling Published: December, 2023 Abstract:
Single-cell chromatin accessibility has emerged as a powerful means of understanding the epigenetic landscape of diverse tissues and cell types, but profiling cells from many independent specimens is challenging and costly. Here we describe a nove... Read more »
A fast and inexpensive plate-based NGS library preparation method for insect genomics Published: November, 2023 Abstract:
Entomological sampling and storage conditions often prioritise efficiency, practicality and conservation of morphological characteristics, and may therefore be suboptimal for DNA preservation. This practice can impact downstream molecular applicat... Read more »
Combined Analysis of mRNA Expression and Open Chromatin in Microglia Published: August, 2023 Abstract:
The advance of single-cell RNA-sequencing technologies in the past years has enabled unprecedented insights into the complexity and heterogeneity of microglial cell states in the homeostatic and diseased brain. This includes rather complex proteom... Read more »
Volumetric imaging of an intact organism by a distributed molecular network Published: August, 2023 Abstract:
