Exposure of male mice to nicotine leads to metabolic dysfunction in their male and female offspringJournal of the Endocrine Society · 2026
Summary (written by the submitters)
Paternal exposure to nicotine has been linked to altered metabolic phenotypes in offspring, yet the underlying mechanisms and sex-specific outcomes remain elusive. In this study, we investigated the effects of paternal nicotine exposure on glucose metabolism, and adipose tissue and liver transcriptomic profiles in male and female offspring.

Despite no differences in body weight during early postnatal life, female offspring displayed lower fasting glucose and reduced glucose levels during glucose tolerance tests, without alterations in insulin sensitivity. These effects were accompanied by decreased circulating insulin and upregulation of genes involved in the insulin signaling pathway in gonadal white adipose tissue (gWAT), consistent with enhanced glucose uptake capacity. In contrast, male offspring showed no overt changes in glucose tolerance or insulin sensitivity, despite reduced plasma insulin and glucagon levels. In male offspring, liver transcriptomic analyses revealed downregulation of glucagon signaling, insulin resistance, and PPARα pathways, suggesting impaired fasting adaptation and reduced hepatic catabolic capacity. Collectively, these findings demonstrate that paternal nicotine exposure induces sex-dependent metabolic reprogramming, with pronounced effects on glucose homeostasis in females and transcriptional signatures of reduced fasting resilience in males. These results identify the liver and adipose tissue as key targets of paternal nicotine exposure in the offspring and underscore the need for longitudinal studies to determine whether these alterations predispose offspring to metabolic disease across the lifespan

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE313674_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.

Study design
40 samples, each with a distinct title — no replicated groups

Any grouping that defines a comparison lives in the sample characteristics, which GEO records separately from the titles.

How we read this: Read from 40 sample titles: 40 distinct titles with little repetition. These groups are guessed from the sample names, not taken from the paper, so check them against the sample list below before relying on them.
