A palmitate-rich metastatic niche enables metastasis growth via p65 acetylation

This study identifies palmitate-rich metastatic niches as promoters of metastasis by enhancing p65 acetylation and NF-κB signaling in breast cancer cells.

4EBP1/2 support tumorigenicity and cell survival during energetic stress by translationally regulating fatty acid synthesis

This study shows 4EBP1/2 promote cell survival under glucose starvation by repressing fatty acid synthesis and maintaining redox balance, supporting tumorigenicity in cancer cells.

Heterogeneity in PHGDH protein expression potentiates cancer cell dissemination and metastasis

This study identifies PHGDH protein expression heterogeneity as a driver of breast cancer metastasis by altering metabolic pathways and promoting dissemination.

PCK2 opposes mitochondrial respiration and maintains the redox balance in starved lung cancer cells

This study shows PCK2 regulates mitochondrial respiration and redox balance in starved lung cancer cells by modulating TCA cycle intermediates and glutathione oxidation.

Repurposing the antidepressant sertraline as SHMT inhibitor to suppress serine/glycine synthesis addicted breast tumor growth.

This study repurposes sertraline as an inhibitor of serine hydroxymethyltransferase to target serine/glycine synthesis in breast cancer, showing synergistic antitumor effects with mitochondrial inhibitors.

Age-induced methylmalonic acid accumulation promotes tumor progression and aggressiveness

The paper shows that methylmalonic acid accumulation with age promotes tumor progression by inducing SOX4 and reprogramming cancer cells.

Cell density-dependent ferroptosis in breast cancer is induced by accumulation of polyunsaturated fatty acid-enriched triacylglycerides

This study shows that low cell density in breast cancer cells increases ferroptosis sensitivity by promoting PUFA-enriched TAG accumulation and reducing lipid desaturation.
