Gelsolin's Protective Role in MASH through F‐Actin Regulation and P53 Degradation

open access: yesAdvanced Science, EarlyView.
Gelsolin (GSN) maintains liver metabolic homeostasis by promoting MDM2‐mediated P53 degradation and inhibiting F‐actin/Yes‐associated protein (YAP) overactivation. Loss of GSN impairs P53 degradation, increases lipid deposition, and enhances YAP‐driven fibrosis and inflammation in metabolic‐associated steatohepatitis.

Pyruvate Carboxylase in Macrophages Aggravates Atherosclerosis by Regulating Metabolism Reprogramming to Promote Inflammatory Responses Through the Hypoxia‐Inducible Factor‐1 Signaling Pathway

open access: yesAdvanced Science, EarlyView.
This study investigates the role of macrophage pyruvate carboxylase (PC) in atherosclerosis (AS) demonstrating that PC upregulation in macrophages promotes metabolism reprogramming to enhance inflammatory responses via the HIF‐1 signaling pathway.

SCORT–Cas13d Nanotherapy Precisely Targets the ‘Undruggable’ Transcription Factor HoxB13 in Metastatic Prostate Cancer In Vivo

open access: yesAdvanced Science, EarlyView.
SCORT–Cas13d–pre‐gHoxB13 lipid nanoparticles precisely deliver Cas13d mRNA and guide RNAs to metastatic prostate tumors in the liver, knocking down the “undruggable” transcription factor HoxB13. This approach suppresses metastatic tumor growth, extends mouse survival, and does not induce major organ toxicity or immune activation, offering a safe and ...

The integrated model of cAMP-dependent DNA expression reveals an inverse relationship between cancer and neurodegeneration [PDF]

open access: yesarXiv, 2016
The model for cAMP-dependent synaptic plasticity relates the characterization of a noradrenaline-stimulated adenylyl cyclase with DNA unzipping. Specific proteins condition cAMP insertion in specific sites of the DNA structure to direct cellular and synaptic differentiation in brain tissues, also providing coding. Metabolic-dependent ATP binding of Mg2+

The INAVA mRNA in Extracellular Vesicles Activates Normal Ovarian Fibroblasts by Phosphorylation–Ubiquitylation Crosstalk of HMGA2

open access: yesAdvanced Science, EarlyView.
Ovarian cancer‐derived extracellular vesicles (EVs) transfer INAVA mRNA to normal ovarian fibroblasts (NOFs). Translated INAVA protein inhibits HMGA2 phosphorylation‐dependent ubiquitylation and proteasomal degradation, promoting NOF activation.

Does quantum entanglement in DNA synchronize the catalytic centers of type II restriction endonucleases? [PDF]

open access: yesarXiv, 2014
Several living systems have been examined for their apparent optimization of structure and function for quantum behavior at biological length scales. Orthodox type II endonucleases, the largest class of restriction enzymes, recognize four-to-eight base pair sequences of palindromic DNA, cut both strands symmetrically, and act without an external ...

Coexistence of Wolbachia with Buchnera aphidicola and a secondary symbiont in the aphid Cinara cedri.

open access: yes, 2004
Intracellular symbiosis is very common in the insect world. For the aphid Cinara cedri, we have identified by electron microscopy three symbiotic bacteria that can be characterized by their different sizes, morphologies, and electrodensities.

The E3 Ubiquitin Ligase ARIH1 Facilitates Colorectal Cancer Progression by Promoting Oxidative Phosphorylation via the Mitochondrial Translocation of K63‐Linked Ubiquitinated PHB1

open access: yesAdvanced Science, EarlyView.
The RBR E3 ubiquitin ligase ARIH1, which is upregulated in colorectal cancer cells, promotes cell growth and metastasis and correlates with an unfavorable CRC prognosis. Mechanistically, ARIH1 catalyzes K63‐linked ubiquitination of PHB1, enhancing the interaction between PHB1 and Akt.

Targeting GPX4 to Induce Ferroptosis Overcomes Chemoresistance Mediated by the PAX8‐AS1/GPX4 Axis in Intrahepatic Cholangiocarcinoma

open access: yesAdvanced Science, EarlyView.
PAX8‐AS1 drives chemoresistance in intrahepatic cholangiocarcinoma by activating NRF2‐mediated GPX4 transcription and stabilizing GPX4 mRNA via IGF2BP3. Targeting the PAX8‐AS1/GPX4 axis with a GPX4 inhibitor enhances the efficacy of gemcitabine and cisplatin in preclinical models, offering a promising strategy to overcome chemotherapy resistance in ...
