Abstract

The adult healthy human pancreas has been poorly studied given the lack of indication to obtain tissue from the pancreas in the absence of disease and rapid postmortem degradation. We obtained pancreata from brain dead donors, thus avoiding any warm ischemia time. The 30 donors were diverse in age and race and had no known pancreas disease. Histopathologic analysis of the samples revealed pancreatic intraepithelial neoplasia (PanIN) lesions……….

Multi-omic single-cell velocity models epigenome-transcriptome interactions and improves cell fate prediction

Chen Li, Maria C Virgilio, Kathleen L Collins, Joshua D Welch

Abstract

Multi-omic single-cell datasets, in which multiple molecular modalities are profiled within the same cell, offer an opportunity to understand the temporal relationship between epigenome and transcriptome. To realize this potential, we developed MultiVelo, a differential equation model of gene expression that extends the RNA velocity framework to incorporate epigenomic data……

Recording of cellular physiological histories along optically readable self-assembling protein chains.

Linghu C, An B, Shpokayte M, Celiker OT, Shmoel N, Zhang R, Zhang C, Park D, Park WM, Ramirez S, Boyden ES.Nat Biotechnol. 2023 Jan 2. doi: 10.1038/s41587-022-01586-7. Online ahead of print.PMID: 36593405

Abstract

Observing cellular physiological histories is key to understanding normal and disease-related processes. Here we describe expression recording islands-a fully genetically encoded approach that enables both continual digital recording of biological information within cells and subsequent high-throughput readout in fixed cells.

SpaceX: gene co-expression network estimation for spatial transcriptomics

Acharyya S, Zhou X, Baladandayuthapani V.Bioinformatics. 2022 Nov 15;38(22):5033-5041. doi: 10.1093/bioinformatics/btac645.PMID: 36179087

Abstract

Motivation: The analysis of spatially resolved transcriptome enables the understanding of the spatial interactions between the cellular environment and transcriptional regulation. In particular, the characterization of the gene-gene co-expression at distinct spatial locations or cell types in the tissue enables delineation of spatial co-regulatory patterns as opposed to standard differential single gene analyses…….See publication for more….

Abstract

Spatial transcriptomics are a collection of genomic technologies that have enabled transcriptomic profiling on tissues with spatial localization information. Analyzing spatial transcriptomic data is computationally challenging, as the data collected from various spatial transcriptomic technologies are often noisy and display substantial spatial correlation across tissue locations. ….learn more
