Disruption of NF‐κB‐Mediated Copper Homeostasis Sensitizes Breast Cancer to Cuproptosis

open access: yesAdvanced Science, EarlyView.
This study reveals a feedback mechanism regulating copper homeostasis, in which copper directly interacts with TAK1 to activate NF‐κB signaling, while NF‐κB transcriptionally suppresses copper transporter (CTR1) expression. These findings highlight a promising therapeutic strategy for breast cancer by combining NF‐κB inhibitors with copper chelators or

Lactate Activates the HCAR1/β‐Arrestin2/PP2A Signaling Axis to Mediate STAT1/2 Dephosphorylation and Drive Osteosarcoma Progression

open access: yesAdvanced Science, EarlyView.
In the present study, it is found that in osteosarcoma, lactate‐activated HCAR1 promotes β‐arrestin 2 translocation from cytoplasm to nucleus. In the nucleus, β‐arrestin 2 recruits PP2A to the activated STAT1/2 dimers, mediating STAT1/2 dephosphorylation and inhibiting the transcription of downstream anti‐oncogenes to promote OS progression.

A Natural Major Module Confers the Trade‐Off between Phenotypic Mean and Plasticity of Grain Chalkiness in Rice

open access: yesAdvanced Science, EarlyView.
This study reveals the genetic and molecular mechanisms controlling the general trade‐off between phenotypic mean and plasticity of grain chalkiness in rice and identifies two major external drivers (high temperature and wide grain) and a natural major module (GCP6‐MPC5) that control this trade‐off.

Adenylosuccinate Synthase 1 Deficiency Improves Energy Metabolism by Promoting Adipose Tissue Re‐esterification via Glycerol Kinase Upregulation

open access: yesAdvanced Science, EarlyView.
Working model of Adss1‐mediated regulation of energy metabolism in adipose tissue. In beige adipocytes, Adss1 interacts with HDAC3 in the cytoplasm, and its loss reduces nuclear HDAC3 while increasing cytosolic fractions. This redistribution suppresses HDAC activity and enhances H3K27 acetylation at the Gk promoter, leading to transcriptional ...

eIF4E Enriched Extracellular Vesicles Induce Immunosuppressive Macrophages through HMGCR‐Mediated Metabolic Rewiring

open access: yesAdvanced Science, EarlyView.
Here, it is revealed that ovarian cancer cells release extracellular vesicles enriched with eIF4E, which alters protein production in macrophages. This leads to increased expression of 3‐hydroxy‐3‐methyl‐glutaryl‐coenzyme A reductase (HMGCR), boosting cholesterol synthesis and activating an immunosuppressive pathway through X‐box binding protein 1 and ...
