Study: Gene expression changes in mice induced by parabiosis and recovery [RNA-seq]
show Abstracthide Abstract
Aging is classically conceptualized as an ever-increasing trajectory of damage accumulation and loss of function, leading to increases in morbidity and mortality. However, recent in vitro studies have raised the possibility of age reversal. We characterized several models in which biological age is perturbed. Heterochronic parabiosis and recovery from this procedure is one such example. Overall design: We studied a mouse model of heterochronic parabiosis. Mouse pairs (either age-mismatched, heterochronic; or age-matched, isochronic) were surgically joined and maintained for 1-3 months. After this period, a subset of mice were euthanized and tissues were collected for analysis, and another subset of pairs was surgically detached and allowed to recover for 2 months, after which tissues were collected. We sequenced RNA isolated from these samples to analyze gene expression changes.
Sample: RNA from liver from OldHetRec2

Organism: Mus musculus
Library:
Name: GSM7585195
Instrument: Illumina NovaSeq 6000
Strategy: RNA-Seq
Source: TRANSCRIPTOMIC
Selection: cDNA
Layout: PAIRED
Construction protocol: RNA was isolated from mouse tissues using the Ambion RNAqueous Total RNA Isolation Kit (Invitrogen). ~25 mg of solid tissue was used as starting material. Concentration of RNA samples was determined using the Qubit RNA HS assay kit (Invitrogen). Total RNA isolated as described above was checked for quality using an Agilent 2100 Bioanalyzer. Messenger RNA was purified from total RNA using poly-T oligo-attached magnetic beads. After fragmentation, the first strand cDNA was synthesized using random hexamer primers followed by the second strand cDNA synthesis. The library was ready after end repair, A-tailing, adapter ligation, size selection, amplification, and purification. The library was checked with Qubit and real-time PCR for quantification and bioanalyzer for size distribution detection.
