Mouse hypothalamus — 27 vs 6 months (bulk RNA-seq)
Mus musculus · Whole hypothalamus · bulk RNA-seq
Selected data and study scope
This dataset contains bulk RNA-seq data from Mus musculus, sampled from whole hypothalamus. The default comparison examines gene expression in Aged (27 months) relative to Young (6 months).
The explorer includes 1 track and 1 comparison for this dataset.
The default track, Whole hypothalamus, includes 16 Young (6 months) samples and 20 Aged (27 months) samples in this comparison. These are analysis sample counts. Check the source for biological replication and pooling.
Interpretation and limitations
The measurement combines expression from the cells in the tissue sample. A difference in tissue expression alone does not identify which cell type contributes to it.
Expression values are CPM (TMM-normalized): counts per million on library sizes adjusted by the TMM factors of the study’s own edgeR fit. This scale adjusts for library size and composition, not gene length. Use it to inspect a feature across the samples in this analysis. CPM values are not absolute transcript counts.
Evidence and verification
Pipeline QC passed. Mouse hypothalamus — 27 vs 6 months (bulk RNA-seq); all 1 registered contrasts on default track hypothalamus
Experimental design passed. Mouse hypothalamus — 27 vs 6 months (bulk RNA-seq); all 1 registered contrasts on default track hypothalamus
Author concordance not assessed. Author effect concordance has not been assessed
Pipeline QC can pass while experimental-design limitations remain. Read both assessments before interpreting results.
Open the dataset in the Explorer to read each check and its evidence. Author concordance compares effects for matched genes. It does not require identical author P values or FDR.
