Hypothalamic fasting and feeding datasets

This guide covers hypothalamic expression studies of food deprivation, dietary restriction and feeding schedules. Short fasting experiments are listed separately from interventions in food amount or timing. Choose a comparison that matches the duration and tissue or cell preparation you need.

A paper about feeding does not always have a feeding comparison available in HypoExplorer. This guide excludes cell-subtype and knockout comparisons whose groups remain fed, even when they belong to the library's broader Feeding & fasting category. The links below identify the baseline and case groups in HypoExplorer.

How to choose and compare studies

Fasting duration and collection time matter

The selected whole-hypothalamus studies range from 16 to 72 hours of food deprivation. GSE254155 samples at ZT16, while the AGRP RiboTag study GSE124693 fixes collection at ZT14. Treat duration and circadian collection time as design variables when comparing results. Choosing the larger effect does not resolve an apparent disagreement between studies.

Check the cells and RNA collected

GSE68177 has separate sorted AGRP and POMC neuron datasets under the same accession. These are two neuronal populations from one source study, not two independent publications. RiboTag and NuTRAP isolate ribosome-associated RNA, while the whole-hypothalamus single-cell entry GSE87544 is aggregated to mouse pseudobulk in this app.

Restriction and timed feeding ask different questions

Five weeks of dietary restriction in aged mice is not interchangeable with a single fast. The SCN time-restricted-feeding study compares isocaloric Western-diet schedules over a 24-hour collection series and models collection time. Neither contrast should be relabeled simply as fasting-induced obesity or as evidence for a dietary treatment in people.

Whole-hypothalamus food deprivation

Compare fasting windows within the whole hypothalamus. Check the original source pages for the remaining strain, sex and handling details.

AGRP and POMC neuron preparations

Compare the captured neurons and RNA fraction before interpreting differences between these entries.

Food amount and feeding schedule

Compare these longer or scheduled interventions separately from acute deprivation.

Using this research guide

This guide selects studies by the comparisons and assays available in HypoExplorer. It does not combine results into a meta-analysis. Each study page credits the original authors and describes the subset shown in the app.

Follow the gene-search instructions to inspect a gene, or the data and export guide to save results. Read the analysis methods and limitations before interpreting a result. Use the citation guide to credit the original researchers and this app.
