Stable olfactory receptor activation across odor complexityiScience · 2025
Summary (written by the submitters)
Phosphorylation of ribosomal protein S6 (pS6) serves as a molecular marker of neuronal activation by external stimuli. In this study, olfactory epithelium tissues were obtained from mice exposed to binary odor mixtures consisting of acetophenone–decanal or octanal–cis-3-hexenol. To examine how different delivery methods of odor presentation influence neural responses, two paradigms for binary mixtures were employed.

In the “+” condition, the two odorants were directly combined on a single piece of filter paper, allowing interaction prior to volatilization. In contrast, in the “&” condition, the odorants were applied separately to two filter papers placed in close proximity (~1 mm apart), such that the components mixed only in the air upon evaporation. Using these approaches, four experimental odor groups were generated (A+D, A&D, O+C, and O&C), along with a no-odor control, resulting in a total of five groups. Following stimulation, pS6-associated ribosome complexes were isolated from olfactory epithelium lysates through immunoprecipitation, selectively enriching mRNAs undergoing active translation in odor-activated cells. RNA sequencing of these samples enabled transcriptomic profiling within activated neuronal populations, providing insights into gene expression programs associated with distinct delivery methods of binary odor stimulation.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE306619_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: For RNA-seq the counts are usually a table among the supplementary files (look for 'counts', 'expression', 'FPKM' or 'TPM' in the file name). The series matrix of a sequencing study is sometimes nearly empty.
