Selected data and study scope

This dataset contains bulk RNA-seq data from Phodopus sungorus, sampled from whole hypothalamus. The default comparison examines gene expression in Short-photoperiod spontaneous torpor relative to Short-photoperiod normothermia.

The explorer includes 1 track and 1 comparison for this dataset.

The default track, Whole hypothalamus, includes 4 Short-photoperiod normothermia samples and 4 Short-photoperiod spontaneous torpor 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. Djungarian-hamster hypothalamus — spontaneous daily torpor; all 1 registered contrasts on default track hypothalamus

Experimental design passed. Djungarian-hamster hypothalamus — spontaneous daily torpor; all 1 registered contrasts on default track hypothalamus

Author concordance review needed. Selected author genes only; spontaneous_torpor_vs_normothermia_author_mouse_projection. P values and FDR are contextual. No numerical acceptance route has passed for this scope.

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

Whole-hypothalamus RNA-seq at ZT04 comparing four short-photoperiod hamsters in spontaneous daily torpor with four short-photoperiod normothermic animals, adjusted for sex. Long-photoperiod animals are excluded; fractional RSEM count estimates are keyed by the authors' documented BLASTx projection to mouse GRCm39 GeneIDs and preserved without rounding (PMID 34894101; GSE179663)
