DNMT2‐m5C‐ACLY Axis Promotes Lenvatinib Resistance in Hepatocellular Carcinoma Through Histone Acetylation‐Mediated Notch Pathway

Advanced Science, EarlyView.
Lenvatinib resistance poses a major challenge in advanced hepatocellular carcinoma (HCC). This study reveals that DNMT2 upregulation is a key driver, which stabilizes ACLY mRNA via m5C modification and activates the Notch signaling pathway. Crucially, combining ACLY inhibitors with lenvatinib overcomes resistance and suppresses tumors, offering a ...

In Situ Assembly of Transformable Monopeptide on Activated Neutrophils Attenuates NETs‐Induced Hepatocellular Carcinoma Metastasis by Disrupting NE Nuclear Translocation

Advanced Science, EarlyView.
Activated neutrophils release extracellular traps (NETs) that promote tumor metastasis. FTP‐NPs are develpoed, a peptidic nanomaterial that binds NE on neutrophil membranes, forming NE‐fibril clusters that deactivate NE and prevent NETs formation. This strategy reduces metastasis and enhances the anti‐tumor immune response by targeting NE subcellular ...

Mitochondrial stress in advanced fibrosis and cirrhosis associated with chronic hepatitis B, chronic hepatitis C, or nonalcoholic steatohepatitis

Hepatology, EarlyView., 2022
Adaptive mitochondrial mechanisms allow mitochondrial resilience and prevent the worsening of fibrosis, while deregulation of these mechanisms promotes the progression from no/minimal‐mild (F0‐F2) fibrosis to advanced fibrosis and cirrhosis (F3‐F4). Abstract Background and Aims Hepatitis B virus (HBV) infection causes oxidative stress (OS) and alters ...

Boosting Reversible Photocontrol of a Photoxenase by an Engineered Conformational Shift

Angewandte Chemie, EarlyView.
Photocontrol of enzymes with photoswitchable unnatural amino acids hitherto yielded only limited light‐regulation factors (LRFs). Here we boosted the LRF of an imidazole glycerol phosphate synthase variant from ∼15 to ∼100 in a semi‐rational design approach and unraveled the mechanistic fundamentals of this effect via biophysical and computational ...

Fe‐S Protein FDX1 Triggers Tumor‐Intrinsic Innate Immunity via Mitochondrial Nucleic Acids Release to Orchestrate Ferroptosis in CCRCC

Advanced Science, EarlyView.
Restoration of the mitochondrial Fe–S protein FDX1 suppresses clear cell renal cell carcinoma by coupling ferroptosis with tumor‐intrinsic innate immune activation. FDX1 induces mitochondrial dysfunction and mtDNA/mt‐dsRNA release, activating cGAS–STING and RIG‐I/MDA5–MAVS signaling to elicit type I interferon responses, thereby promoting antigen ...

Unnatural Amino Acid and Emerging Chemistry Approaches to Map RNA–Protein Interactions

Angewandte Chemie, EarlyView.
This review highlights emerging chemistries for mapping RNA–protein interactions, including genetically encoded unnatural amino acids, novel photocrosslinkers, and non‐photoactivatable crosslinking systems. We compare their mechanisms, reactivity and applications, outlining how these next‐generation tools enable higher‐resolution, site‐specific ...

Identification of the prebiotic translation apparatus within the contemporary ribosome [PDF]

, 2009
A structural element that could have existed independently in the prebiotic era was identified at the active site of the contemporary ribosome. It is suggested to have functioned as a proto-ribosome catalyzing peptide bond formation and non-coded ...

New approaches to treating chronic obstructive pulmonary disease with Colla corii asini

Animal Models and Experimental Medicine, EarlyView.
Colla corii asini improves chronic obstructive pulmonary disease (COPD) treatment through anti‐inflammatory, antioxidant, immune‐modulatory, and lung‐nourishing effects, addressing current therapeutic challenges via multitarget mechanisms. Abstract Chronic obstructive pulmonary disease (COPD) is one of the leading causes of death and disability ...

Translation‐Promoting Effects of RNA Template Overhangs in the Absence of Ribosomes

Angewandte Chemie, EarlyView.
Ribosome‐free translation of an RNA sequence into a peptide sequence can be controlled by the folding of the template strand. Overhang sequences forming a triplex structure with the templating region and the peptidoyl RNA in pH‐dependent manner increase yields up to 40‐fold through entropic effects and mixed anhydride formation, allowing for controlled,
