Inhibition of SIRT7 Overcomes Radioresistance in Pancreatic Neuroendocrine Tumors by Reactivating MEN1 Expression

Advanced Science, EarlyView.
Pancreatic neuroendocrine tumors frequently silence MEN1 through epigenetic mechanisms. Here, SIRT7 recruits DNMT1 to the MEN1 promoter, drives hypermethylation, and enhances DNA repair. Inhibiting SIRT7 restores MEN1, reduces MRN complex abundance, impairs double‐strand break repair, and sensitizes PanNET models to radiation, supporting SIRT7 as a ...

Melatonin and N- Acetylcysteine as Remedies for Tramadol-Induced Hepatotoxicity in Albino Rats [PDF]

Advanced Pharmaceutical Bulletin, 2017
Purpose: The therapeutic benefit derived from the clinical use of tramadol (TD) has been characterized by hepatotoxicity due to misuse and abuse. The implications of drug-induced hepatotoxicity include socio-economic burden which makes the search for ...

Hepatocyte BDNF Acts as a Novel Immune Checkpoint to Restrain TLR4‐Mediated Acute Hepatitis

Advanced Science, EarlyView.
This study identifies hepatocyte‐derived BDNF as an endogenous TLR4 antagonist that alleviates acute hepatitis. BDNF is downregulated in hepatocytes via REST‐mediated transcriptional repression during ALI/ALF. Mechanistically, BDNF binds to TLR4 on macrophages to suppress inflammation.

N-Acetylcysteine in the prevention of ototoxicity [PDF]

Kidney International, 2007
Prevention of ototoxicity after the administration of aminoglycoside antibiotics has been notably difficult, in particular in patients with chronic kidney disease. Feldman et al. report that oral administration of 600 mg N-acetylcysteine twice daily significantly ameliorates gentamicin-induced ototoxicity in hemodialysis patients.

Liver‐Targeted Gallium‐Polyphenol Network by Disrupting the ROS/NETs/PANoptosis Axis for Precision Acute Liver Injury Therapy

Advanced Science, EarlyView.
ABSTRACT Acute liver injury (ALI), driven by diverse insults such as drug toxicity and ischemia‐reperfusion, poses a high mortality risk and lacks targeted therapies. While reactive oxygen species (ROS), neutrophil extracellular traps (NETs), and a coordinated cell death pathway PANoptosis have been implicated, their interplay as a unified pathogenic ...

Regulation of Proliferation by a Mitochondrial Potassium Channel in Pancreatic Ductal Adenocarcinoma Cells [PDF]

, 2017
Previous results link the mitochondrial potassium channel Kv1.3 (mitoKv1.3) to the regulation of apoptosis. By synthesizing new, mitochondria-targeted derivatives (PAPTP and PCARBTP) of PAP-1, a specific membrane-permeant Kv1.3 inhibitor, we have ...

ROS‐Responsive Nanobubbles for Dual‐Enhanced Ultrasound and Magnetic Resonance Imaging of Tumor Oxidative Stress

Advanced Science, EarlyView.
We report the development of biotinylated PEGylated bilirubin‐coated perfluoropentane (bt‐PEG‐BR@PFP) nanobubbles, a novel class of ROS‐activatable and dual‐modality contrast agents that amplify both ultrasound (US) and magnetic resonance imaging (MRI) signals in response to elevated ROS.

Methotrexate promotes platelet apoptosis via JNK-mediated mitochondrial damage: Alleviation by N-acetylcysteine and N-acetylcysteine amide [PDF]

, 2015
Thrombocytopenia in methotrexate (MTX)-treated cancer and rheumatoid arthritis (RA) patients connotes the interference of MTX with platelets. Hence, it seemed appealing to appraise the effect of MTX on platelets.

Rewiring NADH Metabolism Through NQO1‐Mediated Redox Cycling for Targeted Follicular Lymphoma Therapy

Advanced Science, EarlyView.
ABSTRACT Follicular lymphoma (FL) remains an incurable B‐cell malignancy with high relapse rates, and conventional therapies are often limited by significant toxicity, highlighting the need for novel treatments. We identified that FL exhibits markedly low expression of NAD(P)H: quinone oxidoreductase 1 (NQO1), a key enzyme required for activating ...
