Nrf2 Drives Epigenetic Reprogramming and Acts as the Master Regulator of KLF4 Expression and Activity in Arsenic‐Induced Transformation

open access: yesAdvanced Science, EarlyView.
Nrf2 isn't just a protector—it's a driver of cancer stemness. The study uncovers how arsenic‐activated Nrf2 directly upregulates KLF4, a key pluripotency factor, fueling oncogenic reprogramming. Through enhancer activation and self‐reinforcing loop, Nrf2 and KLF4 co‐opt gene networks linked to epithelial‐to‐mesenchymal transition and tumor growth ...

5’‐Methylthioadenosine Metabolic Reprogramming Drives H3K79 Monomethylation‐Mediated PAK2 Upregulation to Promote Cadmium‐Induced Breast Cancer Progression by Impairing Autophagic Flux

open access: yesAdvanced Science, EarlyView.
Cadmium, a carcinogenic heavy metal, drives breast cancer progression via metabolic reprogramming and autophagic flux disruption. Multi‐omics revealed cadmium‐induced 5'‐methylthioadenosine depletion activates DOT1L‐mediated H3K79me1 at PAK2 promoter, upregulating PAK2 to block autophagy and driving malignancy. Clinically, 5'‐methylthioadenosine levels

Osteoblast‐CD4+ CTL Crosstalk Mediated by SIRT1/DAAM2 Axis Prevents Age‐Related Bone Loss

open access: yesAdvanced Science, EarlyView.
In the osteoblastic niche, SIRT1 activates and recruits CD4+ CTLs by increasing DAAM2 expression via EZH2 deacetylation and boosting the secretion of key chemokines, such as CCL3, CCL5, and CXCL10. Then, CD4+ CTL directly eliminates senescent osteoblasts in an MHC‐II‐dependent way, thereby slowing down the process of bone ageing and effectively ...

PRDM16 Reduces Cellular Senescence by Upregulating GSTM1

open access: yesAdvanced Science, EarlyView.
Cellular senescence drives aging and aging‐related organ disorders, yet PRDM16's role remains unexplored. This work uncovers that PRDM16 decreases significantly in aged organs, while its loss accelerates cellular senescence and aging‐related organ injury.

Targeting IGF1R Overcomes Armored and Cold Tumor Microenvironment and Boosts Immune Checkpoint Blockade in Triple‐Negative Breast Cancer

open access: yesAdvanced Science, EarlyView.
IGF1R is highly expressed in the armored & cold tumors, and collagen mediates IGF1R at the transcriptional and post‐translational levels to promote TNBC cell invasion and immune escape and to stabilize its own structure by interacting with the collagen receptor DDR1.

Life Factors and Melanoma: From the Macroscopic State to the Molecular Mechanism

open access: yesAdvanced Science, EarlyView.
Melanoma, an aggressive skin cancer, arises from dynamic interactions between genetic, environmental, and lifestyle factors. This review explores how age, gender, obesity, diet, exercise, smoking, alcohol, UV exposure, circadian rhythms, and medications influence melanoma risk and progression.

A Prion‐Like Domain in EBV EBNA1 Promotes Phase Separation and Enables SRRM1 Splicing

open access: yesAdvanced Science, EarlyView.
This study discoveries that EBV EBNA1 behaves as a prion‐like protein, verified using cell‐based assays and the Saccharomyces cerevisiae Sup35p prion identification system. The prion‐like domain of EBNA1 drives liquid–liquid phase separation. EBNA1 interacts with the splicing factor SRSF1 to regulate the expression of the SRRM1 splicing isoforms ...

Influences of superfine-grinding and mix enzymatic hydrolysis combined with hydroxypropylation or acetylation on the structure and physicochemical properties of jujube kernel fiber

open access: yesFrontiers in Sustainable Food Systems
IntroductionJujube kernel is a low-cost and abundant fiber resource, but its application in food industry is little because of its lower soluble fiber content and poor physicochemical properties.MethodsIn the current study, jujube kernel fiber (JKF) was ...
