Cattle arcuate nucleus — early-life plane of nutrition
Bos taurus · Arcuate nucleus · bulk RNA-seq
Selected data and study scope
This dataset contains bulk RNA-seq data from Bos taurus, sampled from arcuate nucleus. 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, Arcuate nucleus region, 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 arcuate nucleus — early-life plane of nutrition; all 1 registered contrasts on default track arcuate
Experimental design review needed. Cattle arcuate nucleus — early-life plane of nutrition; all 1 registered contrasts on default track arcuate
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.

Source study
Arcuate-region RNA-seq comparing 14 high-plane with 15 moderate-plane early-life nutrition heifer calves. The official author-normalized fractional count-abundance matrix is symbol-collapsed on the linear scale and transformed exactly as log2(x+1) for limma; BioProject PRJNA642856 is the same study record (PMID 34234169; GSE153498)
