NMR studies on structure and dynamics of the monomeric derivative of BS-RNase: new insights for 3D domain swapping. [PDF]

PLoS ONE, 2012
Three-dimensional domain swapping is a common phenomenon in pancreatic-like ribonucleases. In the aggregated state, these proteins acquire new biological functions, including selective cytotoxicity against tumour cells.

Localization of Disulfide Bonds in Ribonuclease Using Low pH Trypsin and LC-ESI-QTOF-MS

CHIMIA
We evaluated a method to localize disulfide bonds in bovine pancreatic ribonuclease (RNase) by applying low pH trypsin protein digestion with a bottom-up LC-ESI-QTOF-MS approach.

Endowing Human Pancreatic Ribonuclease with Toxicity for Cancer Cells*

Journal of Biological Chemistry, 2001
Onconase® is an amphibian protein that is now in Phase III clinical trials as a cancer chemotherapeutic. Human pancreatic ribonuclease (RNase 1) is homologous to Onconase® but is not cytotoxic. Here, ERDD RNase 1, which is the L86E/N88R/G89D/R91D variant

Malformin A1–mediated cytotoxicity in ovarian cancer cells occurs through pyroptosis and autophagy

FEBS Open Bio, EarlyView.
This study investigated the effects of the natural compound Malformin A1 (MA1) on the cytoskeleton that regulates cell proliferation and migration. Disruption of the cytoskeleton can impair these processes and promote cancer cell death. MA1 disrupted cytoskeletal organization, induced DNA damage, inflammation, activated autophagy, and pyroptosis ...

Conserved amino acid networks modulate discrete functional properties in an enzyme superfamily

Scientific Reports, 2017
In this work, we applied the sequence-based statistical coupling analysis approach to characterize conserved amino acid networks important for biochemical function in the pancreatic-type ribonuclease (ptRNase) superfamily.

Ribonuclease (RNase) Prolongs Survival of Grafts in Experimental Heart Transplantation

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundCell damage, tissue and vascular injury are associated with the exposure and release of intracellular components such as RNA, which promote inflammatory reactions and thrombosis. Based on the counteracting anti‐inflammatory and cardioprotective

Accurate and noninvasive prostate cancer detection using plasma‐derived extracellular vesicle RNA

FEBS Open Bio, EarlyView.
Plasma extracellular vesicles were captured with WGA‐conjugated magnetic beads and profiled for RNA biomarkers. A three‐RNA panel (NM_024955, NR_047469, and NR_002564) distinguished prostate cancer from healthy controls and benign prostatic hyperplasia, supporting a simple, noninvasive approach to improve prostate cancer detection.

A rat pancreatic ribonuclease fused to a late cotton pollen promoter severely reduces pollen viability in tobacco plants

Genetics and Molecular Biology, 2000
The effects of an animal RNase fused to the late cotton pollen-specific promoter G9 in a plant system were investigated. Expression of the chimeric genes G9-uidA and G9-RNase in tobacco plants showed that the 1.2-kb promoter fragment of the G9 gene was ...

Lignin Mimicking Protein Methylation Augments the Efficacy of FOLFOX Chemotherapy by Anchoring Thymidylate Synthase

Advanced Materials, EarlyView.
Lignin‐mimicking protein methylation can enhance the efficacy and mitigate the toxicity of the classic FOLFOX chemotherapy regimen. ABSTRACT FOLFOX has served as the standard chemotherapy regimen for advanced stages, specifically in the treatment of pancreatic, colorectal, and bladder cancers.

Mitigating Cancer Therapy–Related Cognitive Impairment by Targeted Activation of Undruggable Phosphatase

Advanced Science, EarlyView.
An RVG‑engineered exosomal saRNA delivery system (RVG‑EVs‑saPtpro) effectively targets and activates hippocampal PTPRO, functioning as a “molecular brake” to alleviate cancer therapy‑related cognitive impairment (CTRCI) by enhancing neuronal survival, neurogenesis, and synaptic plasticity.
