Gut Metabolite Indole‐3‐Propionic Acid Regulates Macrophage Autophagy Through PPT1 Inhibiting Aging‐Related Myocardial Fibrosis

open access: yesAdvanced Science, EarlyView.
IPA is an intestinal tryptophan metabolite whose effects decline with decreased heart function. Supplementing IPA can alleviate the aging‐related myocardial fibrosis through PPT1. PPT1 is a key protein localized to lysosomes, and IPA can restore macrophage autophagy function by regulating PPT1 expresssions, thereby reducing aging‐related myocardial ...

Cytokine Storm Induction Linked to Multi‐Organ Failure in Fatal Jellyfish Stings

open access: yesAdvanced Science, EarlyView.
N. nomurai is the most important injurious species in the coastal area of China. Model construction, omics analysis, mechanism exploration, and intervention measures of N. nomurai envenomation are performed in the current study, and it suggested that cytokine storm played an important role in pathogenesis.

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 ...

RPL6 Interacts with HMGCS1 to Stabilize HIF‐1α by Promoting Cholesterol Production in Hepatocellular Carcinoma

open access: yesAdvanced Science, EarlyView.
The study found that RPL6 is frequently upregulated in HCC tissues with extrahepatic metastasis. Elevated RPL6 bound to and increased the stability of HMGCS1 mRNA, thereby enhancing intracellular cholesterol levels. Subsequently, increased cholesterol promotes cancer metastasis in HCC by stabilizing HIF‐1α protein.

Ubiquitination‐Dependent LLGL2 Degradation Drives Colorectal Cancer Progression via THBS3 mRNA Stabilization

open access: yesAdvanced Science, EarlyView.
During the progression of CRC, MDM2, as an E3 ubiquitin ligase, promotes the degradation of the LLGL2 protein. Reduced expression of the LLGL2 protein leads to the loss of support for the CNOT1 protein, decreasing the degradation of THBS3 mRNA. The increased THBS3 further activates the PI3K‐Akt pathway, promoting the proliferation and metastasis of CRC.
