Selected data and study scope

This dataset contains bulk RNA-seq data from Bos taurus, sampled from whole hypothalamus. The default comparison examines gene expression in High plane of nutrition relative to Moderate plane of nutrition.

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

The default track, Remaining hypothalamus, includes 15 Moderate plane of nutrition samples and 14 High plane of nutrition 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 use log2(TMM-normalized count abundance + 1). Keep this unit when exporting or comparing values. Values on other normalization scales are not directly interchangeable.

Evidence and verification

Pipeline QC passed. Cattle hypothalamus — early-life plane of nutrition; all 1 registered contrasts on default track hypothalamus

Experimental design review needed. Cattle hypothalamus — early-life plane of nutrition; all 1 registered contrasts on default track hypothalamus

Author concordance review needed. Selected author genes only; high_vs_moderate_plane_nutrition. 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.
