An integrative single‐cell atlas across multiple metabolic diseases reveals coordinated metabolic modules and disease‐shared versus disease‐specific pathway activities. By systematically comparing scoring strategies, a robust RankAve framework is established. Coupled with network analysis and drug‐target prediction, this resource uncovers cross‐disease

Slc44a2 Deficiency Unveils an IFN‐I–Dependent Feedback Control of pDC Egress
Working model of SLC44A2‐mediated maintenance of pDC homeostasis. This model illustrates two central mechanisms by which SLC44A2 regulates pDC homeostasis: (1) SLC44A2 limits IFN‐I production by exporting amino acids (T, N, Q), thereby preventing spontaneous pDC activation.

GCN2 kinase activation mediates pulmonary vascular remodeling and pulmonary arterial hypertension
Pulmonary arterial hypertension (PAH) is characterized by progressive increase of pulmonary vascular resistance and remodeling that result in right heart failure.

Hypothalamic eIF2α Signaling Regulates Food Intake
The reversible phosphorylation of the α subunit of eukaryotic initiation factor 2 (eIF2α) is a highly conserved signal implicated in the cellular adaptation to numerous stresses such as the one caused by amino acid limitation.

An ISR-independent role of GCN2 prevents excessive ribosome biogenesis and mRNA translation
GCN2 restrains ribosome biogenesis at mRNA and translational levels, keeps protein synthesis in check, and maintains metabolic homeostasis independently of the ISR in a subset of cancers. The integrated stress response (ISR) is a corrective physiological

A GCN1-independent activator of the kinase GCN2
Abstract Mutations of EIF2AK4, which encodes the eIF2α kinase GCN2, cause a severe inherited form of pulmonary hypertension called pulmonary veno-occlusive disease (PVOD). Some pathogenic variants of GCN2 are amenable to pharmacological reactivation by low concentrations of ATP-pocket binding inhibitors.

mTORC1 senses glutamine and other amino acids through GCN2
mTORC1 promotes cell growth when nutrients such as amino acids are available. While dedicated sensors relaying availability of leucine, arginine and methionine to mTORC1 have been identified, it is still unclear how mTORC1 senses glutamine, one of its ...

General control nonderepressible 2 (GCN2) as a therapeutic target in age-related diseases
The function of General Control Nonderepressible 2 (GCN2), an evolutionary-conserved component of the integrated stress response (ISR), has been well-documented across organisms from yeast to mammals.

Nutrient availability is a key determinant of tumor cell behavior. While nutrient‐rich conditions favor proliferation and tumor growth, scarcity, and particularly glutamine starvation, promotes cell dedifferentiation and chemoresistance.
