Deamidation of Proteins: The crystal structure of bovine pancreatic ribonuclease with an isoaspartyl residue at position 67 [PDF]

, 1996
The non-enzymatic deamidation of asparagine residues in proteins is a widely occurring reaction, both in vivo and in vitro. Although the importance of this process is commonly recognised, only little structural information is available on it. In order to

Gut Parabacteroides distasonis‐derived Indole‐3‐Acetic Acid Promotes Phospholipid Remodeling and Enhances Ferroptosis Sensitivity via the AhR‐FASN Axis in Bladder Cancer

Advanced Science, EarlyView.
Indole‐3‐acetic acid (3‐IAA) derived from gut P. distasonis binds to AhR in bladder cancer cells and downregulates FASN transcription, thereby increasing sensitivity to ferroptosis and suppressing the development of bladder tumors. Specifically, 3‐IAA treatment leads to an increase in the proportion of PC/PE‐PUFAs and a decrease in the proportions of ...

Metal‐Responsive Up‐Regulation of Bifunctional Disulfides for Suppressing Protein Misfolding and Promoting Oxidative Folding

Angewandte Chemie, EarlyView.
A stress‐responsive folding promotor was developed by conjugating metal‐binding ligands and a redox‐active disulfide. The oxidative strength of the bifunctional disulfide was enhanced by metal coordination, inhibiting protein misfolding and up‐regulating the oxidative folding capacity under metal stress.

A human ribonuclease induces apoptosis associated with p21^WAF1/CIP1 induction and JNK inactivation

BMC Cancer, 2011
Background Ribonucleases are promising agents for use in anticancer therapy. Among the different ribonucleases described to be cytotoxic, a paradigmatic example is onconase which manifests cytotoxic and cytostatic effects, presents synergism with several

THE IMPORTANCE OF DYNAMIC EFFECTS ON THE ENZYME ACTIVITY: X-RAY STRUCTURE AND MOLECULAR DYNAMICS OF ONCONASE MUTANTS. [PDF]

, 2005
Onconase (ONC), a member of the RNase A superfamily extracted from oocytes of Rana pipiens, is an effective cancer killer. It is currently used in treatment of various forms of cancer.

KRAS mRNA Spleen‐Targeting Lipid Nanoparticles Synergize with Irinotecan Silicasomes to Robustly Augment the Cancer Immunity Cycle in Pancreatic Cancer

Advanced Science, EarlyView.
To overcome pancreatic cancer's immunosuppressive barriers, this study explores a dual approach: triggering immunogenic tumor cell death at the primary tumor site with irinotecan‐loaded silicasomes and enhancing immune activation in the spleen using LNPs encapsulating tumor antigen mRNA and a TLR7/8 agonist.

Targeting Hyperglycemic Bone Pre‐Metastatic Niche for Breast Cancer Bone Metastasis Therapy

Advanced Science, EarlyView.
This study reveals that breast cancer creates a hyperglycemic pre‐metastatic niche in bone prior to colonization and amplifies glucose metabolism post‐metastasis. To target this mechanism, a biomimetic enzyme‐engineered nanoplatform that disrupts tumor glycolytic pathways, proposing a therapeutic strategy to inhibit breast cancer bone metastasis by ...

miRNAs as Regulators of Antidiabetic Effects of Fucoidans [PDF]

, 2019
open access articleDiabetes mellitus is a metabolic disease with a high mortality rate worldwide. MicroRNAs (miRNAs), and other small noncoding RNAs, serve as endogenous gene regulators through binding to specific sequences in RNA and modifying gene ...

The Long Noncoding RNA ΒFaar Promotes White Adipose Tissue Browning and Prevents Diet‐Induced Obesity

Advanced Science, EarlyView.
βFaar selectively targets and inhibits the GTPase activity of the RAB18 protein, thereby reducing LD volume. Conversely, βFaar promotes nuclear translocation of the transcription factor IRF4 in inguinal white adipose tissue (iWAT), facilitating the browning of white adipose tissue and attenuating body fat accumulation.

Gemcitabine exhibits a suppressive effect on pancreatic cancer cell growth by regulating processing of PVT1 to miR1207

Molecular Oncology, 2018
Gemcitabine serves as a first‐line chemotherapy agent for advanced pancreatic cancer (PC). However, the molecular basis by which gemcitabine exerts its effects is not well‐established, and the targeted genetic pathways remain unclear.
