Zebrafish hypothalamus — cyp19a1b mutation
Danio rerio · Whole hypothalamus · bulk RNA-seq
Selected data and study scope
This dataset contains bulk RNA-seq data from Danio rerio, sampled from whole hypothalamus. The default comparison examines gene expression in cyp19a1b mutant relative to Wild type.
The explorer includes 1 track and 1 comparison for this dataset.
The default track, Whole hypothalamus, includes 6 Wild type samples and 5 cyp19a1b mutant 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. Zebrafish hypothalamus — cyp19a1b mutation; all 1 registered contrasts on default track hypothalamus
Experimental design passed. Zebrafish hypothalamus — cyp19a1b mutation; all 1 registered contrasts on default track hypothalamus
Author concordance review needed. Selected author genes only; cyp19a1b_mutant_vs_wild_type_male. P values and FDR are contextual. Numerical acceptance: matched-gene direction.
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.

Source study
Adult male hypothalamus RNA-seq comparing five cyp19a1b-mutant with six wild-type pools, each pool representing three zebrafish. Female, olfactory-bulb, and telencephalon samples are excluded; integer UMI counts are mapped only by exact current zebrafish symbols (PMID 40853063; GSE299412)
