Widespread non-Mendelian inheritance of DNA methylation patterns in mice [ONT Liver - Targeted]

ABSTRACT: We performed long-read ONT sequencing and matched RNA sequencing on two Collaborative Cross mouse strains and their F1 crosses. Allele-specific methylation and expression analyses revealed widespread and diverse patterns of intergenerational epigenetic inheritance. Included among these are a large number of non-Mendelian inheritance patterns, many of which have not previously been observed in naturally occurring mammalian genomes. Targeted ONT sequencing of F2 crosses of the same Collaborative Cross strains enabled further characterization and validation of these epigenetic inheritance patterns, including distinguishing those patterns mediated by cis- or trans-acting regulatory factors.

Collaborative Cross founder strain lung miRNA expression after allergen challenge

Project description:The goal of this project was to identify strain-dependent expression of miRNAs in lung tissue from Collaborative Cross founder strains that were sensitized and challenged with house dust mite allergen (Der p 1). We analyzed whole lung RNAs from the eight Collaborative Cross founder strains (n=4/strain, all males) using Affymetrix miRNA 2.0 arrays

Development of ONT-cappable-seq to unravel the transcriptional landscape of Pseudomonas phages

Project description:We developed ONT-cappable-seq, a specialized long-read RNA sequencing technique that allows end-to-end sequencing of primary prokaryotic transcripts using the Nanopore sequencing platform. We applied ONT-cappable-seq to study the transcriptional landscape of Pseudomonas aeruginosa phage LUZ7, leading to a comprehensive genome-wide map of viral transcription start sites, terminators and complex operon structures that fine-regulate gene expression. At the same time, it provides new insights in the RNA biology of LUZ7 and paves the way for more in depth transcription studies that can help unveil the complex layers of phage-host interactions.

Single nucleus RNA sequencing of the cerebral cortex from genetically diverse inbred mouse strains reveals differences in pericyte and endothelial cell composition

Project description:Genetic background influences animal behavior and susceptibility to brain diseases. To evaluate how genetic background influences the relative number and/or types of cells in the brain, we performed single nucleus RNA sequencing on 14 genetically distinct collaborative cross (CC) inbred mouse strains. These data comprise over 287,000 nuclei derived from 92 samples across each of the strains. We identified 11 principal cell types and 59 refined cell types in each of the strains.

Refining the transcriptional maps of Pseudomonas aeruginosa phages using ONT-cappable-seq

Project description:The global transcriptional profiles of Pseudomonas aeruginosa phages LUZ19, LUZ24, YuA, PAK_P3, 14-1 and phiKZ was obtained using the long read RNA sequencing technique ONT-cappable-seq. Using this approach we obtained a comprehensive genome-wide map of viral transcription start sites, terminators and transcription units.
