Museum epigenomics: characterizing cytosine methylation in historic museum specimens

April 2019

Authors:
Tricia L. Rubi, L. Lacey Knowles, Ben Dantzer

Info:
In this preprint, researchers developed method the study epigenetic markers on historically preserved deer mouse specimens using ddRAD-seq and bisulfite sequencing. The oldest group of specimens was 76 years old.

The Pippin Prep was used to size select ddRAD libraries prepared with an extra bisulfite conversion step. Size selection: 376-412 bp and 325-425 bp for higher and lower concentration preps, respectively.

Comparison of RNA isolation and library preparation methods for small RNA sequencing of canine biofluids

Authors:
Candice P. Chu, Mary B. Nabity

Info:
From the Department of Veterinary Pathobiology at Texas A&M, this study evaluates best practices for small RNA sequencing from canine biofluid samples (serum and urine). The study compares RNA-seq results after using three commercial RNA extraction kits for each biofluid type, and two sequencing library construction kits. A recommendation is provided for isolation/construction for each biofluid, with supporting data.

The PippinHT was used to isolate the small RNA libraries prior to sequencing.

Ip, Hannah E. Roberts, Silvia Salatino, Helen Lockstone, Gerton Lunter, Jenny C. Taylor, David Buck, Michael A. Simpson, Peter Donnelly

Info:
The potential of using Oxford Nanopore Technologies MinION sequencer is evaluated for Whole Genome Sequencing (WGS). A reference sample (NA112878) was sequenced alongside an individual with clinical indications. The authors applied novel bioinformatic approaches to the analysis and identify innovations that could significantly improve the platform’s potential for clinical WGS.

BluePippin was used to enrich DNA fragments >6kb using the High-Pass protocol prior to library construction.

Info:
A new technique is described; Transposon Insertion Profiling (TIPseq). The method uses vectorette PCR and paired-end Illumina sequencing to map (LINE-1, L1) retrotransposon insertions in the human genome. A detailed protocol is provided.

Pippin Prep is used to remove fragments below 400 bp from libraries prior to sequencing.

Identification of whole blood mRNA and microRNA biomarkers of tissue damage and immune function resulting from amphetamine exposure or heat stroke in adult male rats

February 2019

Info:
A report from the USDA and others evaluate the effect of amphetamine and methamphetamine toxicity on immune systems and tissues using rat models. In particular, hyperthermic effects, due to the drug exposure or environmentally induces were studied. With hyperthermia, an increase in organ related transcripts were indicated and as was possible liver damage. In addition, changes to the immune system suggest modified risk of for HIV and other infections.

The PippinHT was used to isolated small RNA (15-35bp) Illumina libraries prior to sequencing.
