Summary (written by the submitters)

During perinatal development, liver metabolism is tightly regulated to ensure energy supply for the newborn. Before birth, glycogen is stored in hepatocytes and later metabolized to glucose, meeting the energy demands of the neonate. Shortly after birth, lipogenesis begins, driven by the transcriptional activation of enzymes involved in fatty acid oxidation.

These processes are thought to be largely regulated by systemic insulin and glucagon levels. However, the role of liver-derived local factors in neonatal hepatocyte metabolism remains unexplored. Kupffer cells (KCs), the liver’s resident macrophages, colonize the fetal liver early in embryogenesis and support liver metabolism in adulthood. Yet, whether KCs influence neonatal hepatocyte metabolism is unknown. Here, using conditional knockout mouse models targeting macrophages, we demonstrate that yolk sac-derived KCs play a critical role in hepatocyte glycogen storage and function by regulating the TCA cycle - a role that monocyte-derived KC-like cells cannot substitute. Newborn pups lacking KCs mobilize glycogen more rapidly, a process regulated by insulin-like growth factor 1 (Igf1) production. Our findings reveal that macrophages are a major source of Igf1 at birth and that local Igf1 production by KCs is essential for balanced hepatocyte metabolism.

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.

Also filed as BioProject PRJNA1195594 and SRA study SRP550077. Searching any of these in the dataset finder brings you back here.
