GOT1 Inhibition Induces Extracellular Matrix Remodeling in Pancreatic Cancer

Advanced Science, EarlyView.
Using tumor tissue engineering, we recreated pancreatic cancer and found that inhibiting glutamic‐oxaloacetic transaminase 1 (GOT1) induces extracellular matrix remodeling and secretome rewiring, as well as promotes cell death. ABSTRACT Pancreatic cancer cells rely on glutamine to sustain their survival in the stiff and poorly vascularized tumor ...

First biochemical characterization of a novel ribonuclease from wild mushroom Amanita hemibapha [PDF]

, 2012
A 45-kDa ribonuclease (RNase) was purified from dried fruiting bodies of the wild mushroom Amanita hemibapha. It was adsorbed on DEAE-cellulose, S-sepharose, and finally purified on Superdex 75. The RNase exhibited maximal RNase activity at pH 5 and in a

Selenoprotein H Functions as a PPARα Coactivator to Link Selenium Homeostasis to Hepatic Lipid Metabolism and Protect against Steatohepatitis

Advanced Science, EarlyView.
Our study identifies selenium deficiency as a hallmark of MASH pathogenesis. Dietary selenium supplementation enhances hepatic fatty acid oxidation (FAO) and attenuates MASH progression by activating the PPARα pathway via selenoprotein H (SELENOH). This selenium‐SELENOH‐PPARα nexus redefines the functional scope of selenoproteins, moving from redox ...

PROTAC‑Mediated HMGCR Depletion Reprograms Lipid Metabolism in Breast Cancer to Potentiate Photoimmunotherapy via Ferroptosis

Advanced Science, EarlyView.
This work introduces a study that identifies HMGCR as a novel target in TNBC and develops a light‐gated PROTAC nanomedicine. Upon irradiation, this agent selectively degrades HMGCR, reprogramming lipid metabolism to induce ferroptosis and potent antitumor immunity, thereby significantly enhancing photoimmunotherapy efficacy.

PIK3CA Mutations Downregulate PPT1 to Promote Adipogenesis by Suppressing P300 Depalmitoylation and Phase Separation

Advanced Science, EarlyView.
This study demonstrates that somatic PIK3CA mutations suppress PPT1 expression via activation of the PI3K–AKT–c‐JUN axis. This reduction in PPT1 weakens its interaction with P300, thereby increasing palmitoylation at C1176 of P300 and protecting P300 from lysosomal degradation.

Conformational Studies on a Glycosylated Bovine Pancreatic Ribonuclease

Journal of Biological Chemistry, 1973
Abstract Various spectral properties (circular dichroism, optical rotatory dispersion, and ultraviolet denaturation difference spectroscopy) of a glycosylated bovine pancreatic ribonuclease (RNase B') have been measured. This glycoprotein contains an average of 1 mole of glucosamine and 2 to 3 moles of mannose per mole of protein.

Bioinformatics‐based discovery of the involvement of PSAT1 in mediating the anti‐lung adenocarcinoma activity of triptolide

Animal Models and Experimental Medicine, EarlyView.
Transcriptome sequencing was performed on tumor tissues from triptolide‐treated tumor‐bearing mice. The sequencing results were integrated with data from public databases for comprehensive analysis, and potential regulatory targets of triptolide were identified.

Protein disulphide isomerase-induced refolding of sonochemically prepared Ribonuclease A microspheres [PDF]

, 2012
The present communication describes for the first time the development of Ribonuclease A (RNase A) microspheres using the sonochemical method followed by an enzymatic treatment with protein disulphide isomerase (PDI).
