What it is
RNA-seq (gene expression)Gene activity measured by sequencing. The summary does not mention single-cell work, so this is most likely bulk: one average per sample, the usual starting point for comparing groups.

Data you can get
A processed table (series matrix) and supplementary files from NCBI; the raw sequencing reads from ENA. Which of these hold counts depends on the study, so check the file list.
Paper
Impact of modulating leptin sensitivity on the transcriptomic profile of adult-derived hypothalamic mouse neuronsFrontiers in molecular neuroscience · 2024
Summary (written by the submitters)
Modulating leptin sensitivity in hypothalamic neurons is critical for metabolic regulation and plays a key role in the development of obesity. This study examines the effects of three distinct approaches—leptin exposure (LEPA), leptin antagonist administration (LANTA), and palmitate treatment (PA)—on adult-derived mHypoA-2/12 neurons.
Read the full summary ↓
Transcriptomic analysis using 3' mRNA-Seq revealed significant downregulation of several pathways, including the NOD-like receptor signaling pathway, C-type lectin receptor signaling pathway, NF-κB signaling pathway, and IL-17 signaling pathway. These pathways are closely linked to neuroinflammatory processes, suggesting that modulating leptin sensitivity may influence inflammation in the hypothalamus. The observed downregulation indicates a complex interaction between leptin signaling and cellular stress responses, which may represent an adaptive mechanism to prolonged exposure to leptin or fatty acids. Understanding these dynamics is crucial for gaining insight into how neuroinflammation contributes to the development of leptin resistance and related metabolic disorders.

Download · which file do I need?

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.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE280030_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.

Also filed as BioProject PRJNA1175987 and SRA study SRP540148. Searching any of these in the dataset finder brings you back here.

Supports a between-group comparison across 15 samples.

How we read this: 4 replicated groups read from 15 sample titles; they account for 15 of them. 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.
