Project description:Formalin-fixed paraffin-embedded (FFPE) samples represent the gold standard for archiving pathology samples, and thus FFPE samples are a major resource of samples in clinical research. However, chromatin-based epigenetic assays in the clinical settings are limited to fresh or frozen samples, and are hampered by low chromatin yield in FFPE samples due to the lack of a reliable and efficient chromatin preparation method. Here, we introduce a new chromatin extraction method from FFPE tissues (Chrom-EX PE) for chromatin-based epigenetic assays.This study provided a new method that achieves efficient extraction of high-quality chromatin suitable for chromatin-based epigenetic assays with less damage on chromatin.
Project description:Long-read RNA sequencing (RNA-seq) is a powerful technology for transcriptome analysis, but the relatively low throughput of current long-read sequencing platforms limits transcript coverage. We present TEQUILA-seq, a versatile, easy-to-implement, and low-cost method for targeted long-read RNA-seq. TEQUILA-seq can be broadly used for targeted sequencing of full-length transcripts in diverse biomedical research settings.

Project description:AGRP neurons are a hypothalamic population that senses physiological energy deficit and consequently increases appetite. Molecular and cellular processes for energy-sensing and elevated neuronal output are critical for understanding the central nervous system response to energy deficit states, such as during weight-loss. Cell type-specific transcriptomics can be used to identify pathways that counteract weight-loss but, in adult mice, this has been limited by technical challenges. We report high-quality gene expression profiles of AGRP neurons under well-fed and energy deficit states. For comparison, we also analyzed POMC neurons, an intermingled population that suppresses appetite. This data newly identifies cell type-selective involvement of signaling pathways, ion channels, neuropeptides, and G-protein coupled receptors. Combined with methods to validate and manipulate these pathways, this resource greatly expands molecular insight into neuronal regulation of body weight, and may be useful for devising therapeutic strategies for obesity and eating disorders.
