Oxidative Stress: Concept and Some Practical Aspects

Antioxidants, 2020
Oxidative stress is defined as “an imbalance between oxidants and antioxidants in favor of the oxidants, leading to a disruption of redox signaling and control and/or molecular damage”. This Commentary presents basic features of this global concept which

Advanced Oral Delivery Systems for Nutraceuticals

Advanced Healthcare Materials, EarlyView.
Emerging delivery technologies are explored to overcome barriers to oral nutraceutical absorption. Traditional carriers are compared with novel platforms including biodegradable polymers, MOFs, MPNs, and 3D printing. These systems enhance bioavailability, control release, and enable personalized nutrition.

Digitonin‐Loaded Nanoscale Metal–Organic Framework for Mitochondria‐Targeted Radiotherapy‐Radiodynamic Therapy and Disulfidptosis

Advanced Materials, EarlyView.
A mitochondria‐targeted cationic nanoscale metal organic framework shows strong radiotherapy‐radiodynamic therapy effects and selectively releases digitonin in acidic tumor microenvironments to induce disulfidptosis of cancer cells and downregulate immune checkpoints in cancer and T cells, thereby eliciting strong antitumor immunity to effectively ...

Cleavage of Coenzyme B12 by Methylmalonyl Coenzyme A Mutase

Journal of Biological Chemistry, 1973
Abstract Methylmalonyl-CoA mutase-dependent cleavage of coenzyme B12 took place in the presence of succinyl-CoA, one of the substrates of the enzyme, and in the presence of malonyl-CoA, a competitive inhibitor (Ki 0.12 mm). Other competitive inhibitors of the reaction, including acetyl-CoA, propionyl-CoA, glutaryl-CoA, and CoA itself, did not replace ...

UCP2 Upregulates ACSL3 to Enhance Lipid Droplet Release from Acinar Cells and Modulates the Sirt1/Smad3 Pathway to Promote Macrophage‐to‐Myofibroblast Transition in Chronic Pancreatitis

Advanced Science, EarlyView.
These findings suggest that UCP2 promotes LD formation and release in acinar cells by upregulating ACSL3 expression. This alteration in the local lipid metabolic environment indirectly drives the MMT process. Additionally, UCP2 may regulate the acetylation of Smad3 through Sirt1, enhancing its nuclear activity and activating the TGF‐β/ Smad3 signaling ...

Deacetylation of ACLY Mediates RNA M6A‐Modification of NOXA and Promotes Chemoresistance of Colorectal Cancer

Advanced Science, EarlyView.
This study investigates the deacetylation of ACLY at K978 acts as a novel risk in colorectal cancer chemoresistance. The deacetylation of K978 induces ACLY relocation to the nucleus and promotes its binding to RBM15, a m6A methylation modification “writer”.
