Metabolic Deficiencies Underlie Plasmacytoid Dendritic Cell Exhaustion After Viral Infection

This study identifies LDHB as a key regulator of pDC IFN-I production and metabolic capacity during viral infection, linking metabolic deficiencies to pDC exhaustion and its dual role in immunity and pathology.

Glutamine mimicry suppresses tumor progression through asparagine metabolism in pancreatic ductal adenocarcinoma

This study shows that DON inhibits PDAC growth by targeting asparagine metabolism, and combining DON with ASNase reduces metastasis.

Biphasic response of CD8 T cell to asparagine restriction maximizes its metabolic fitness and antitumoral functionality

This study shows that asparagine restriction induces a biphasic response in CD8 T cells, enhancing their metabolic fitness and antitumoral function through ATF4/NRF2-dependent mechanisms.

gamma aminobutyrate (GAB) functions as a bioenergetic and signaling gatekeeper to control T cell inflammation

This study shows GAB controls T cell inflammation by acting as a bioenergetic and signaling gatekeeper through ABAT-dependent anaplerosis and GABA(A) receptor-mediated autocrine signaling.

Metabolic heritage mapping: heterogenous pools of cytoplasmic nucleotide sugars are selectively utilized by various glycosyltransferases

The paper shows that cells use different pools of GDP-fucose for glycosylation, depending on the origin of the monosaccharide, and that this selection is tightly regulated.

Succinate dehydrogenase/complex II is critical for metabolic and epigenetic regulation of T cell proliferation and inflammation

This study shows that succinate dehydrogenase/complex II is essential for T cell proliferation and inflammation by regulating metabolic flux and epigenetic modifications.

Melanoma Addiction to GCDH is Mediated by NRF2 Tumor Suppressor Function

This study identifies melanoma addiction to GCDH, showing that GCDH controls NRF2 glutarylation, which limits apoptotic UPR signaling and tumor growth.

OGT controls mammalian cell viability by regulating the proteasome/mTOR/mitochondrial axis

This study identifies OGT's role in maintaining cell viability by regulating the proteasome/mTOR/mitochondrial axis through amino acid homeostasis and mitochondrial fitness.

MPI8 is Potent Against SARS-CoV-2 by Inhibiting Dually and Selectively the SARS-CoV-2 Main Protease and the Host Cathepsin L

The paper evaluates MPro inhibitors for SARS-CoV-2, finding MPI8 selectively inhibits both MPro and host cathepsin L, enhancing antiviral efficacy with reduced toxicity.

The deacylase SIRT5 supports melanoma viability by regulating chromatin dynamics

This study identifies SIRT5 as essential for melanoma cell survival and tumor formation, showing it regulates chromatin dynamics and gene expression through histone modifications.

A Speedy Route to Multiple Highly Potent SARS-CoV-2 Main Protease Inhibitors

This study designs and synthesizes potent SARS-CoV-2 main protease inhibitors, with some showing IC50 values below 100 nM and high virus inhibition potency in cell assays.

An acidic residue buried in the dimer interface of isocitrate dehydrogenase 1 (IDH1) helps regulate catalysis and pH sensitivity

This paper identifies an acidic residue in IDH1 that regulates catalysis and pH sensitivity through conformational changes.

Defining and targeting adaptations to oncogenic KRASG12C inhibition using quantitative temporal proteomics

This study uses quantitative temporal proteomics to analyze KRASG12C inhibitor responses in cancer models, identifying effective drug combinations to overcome resistance.
