Ribonuclease A can be transformed into a dimeric ribonuclease with antitumor activity

open access: yesJournal of Biological Chemistry, 1994
A cDNA coding for bovine pancreatic RNase A was mutagenized to insert a proline, a leucine, and 2 cysteine residues, i.e. the residues present at corresponding positions in the subunit of seminal RNase, the only dimeric RNase of the pancreatic-type superfamily.

Iron‐dependent lysosomal LDL oxidation induces the expression of scavenger receptor A in human THP‐1 monocytes

open access: yesFEBS Open Bio, EarlyView.
In human monocytic cells THP‐1, a limited uptake of native—not oxidized—LDL/VLDL induced expression of scavenger receptor A and cellular adhesion. Induction was inhibited by lysosomotropic (WR‐1065) and lipophilic (BHT) antioxidants and by siRNAs against ferritinophagy.

A general approach to high-yield biosynthesis of chimeric RNAs bearing various types of functional small RNAs for broad applications. [PDF]

open access: yes, 2015
RNA research and therapy relies primarily on synthetic RNAs. We employed recombinant RNA technology toward large-scale production of pre-miRNA agents in bacteria, but found the majority of target RNAs were not or negligibly expressed. We thus developed a

The major component in schistosome eggs responsible for conditioning dendritic cells for Th2 polarization is a T2 ribonuclease (omega-1)

open access: yesJournal of Experimental Medicine, 2009
Schistosoma mansoni eggs contain factors that trigger potent Th2 responses in vivo and condition mouse dendritic cells (DCs) to promote Th2 lymphocyte differentiation.

Profiling the effect of low frequency mechanical vibration on the metabolic and oxidative stress responses of A431 carcinoma

open access: yesFEBS Open Bio, EarlyView.
20 Hz mechanical vibration induced A431 cancer cells' apoptosis without such effect on other healthy cell lines of L929 and C2C12. Lowered glucose consumption is observed specifically in A431. The expressions of ROS, HMGB1, and HSP1 levels initially increase and subsequently decrease in the cancer cell line, as opposed to L929 and C2C12, which ...

Human mitochondrial degradosome prevents harmful mitochondrial R loops and mitochondrial genome instability [PDF]

open access: yes, 2018
R loops are nucleic acid structures comprising an DNA-RNA hybrid and a displaced single-stranded DNA. These structures may occur transiently during transcription, playing essential biological functions. However, persistent R loops may become pathological

Ribonuclease S dynamics measured using a nitrile label with 2D IR vibrational echo spectroscopy.

open access: yesJournal of Physical Chemistry B, 2012
A nitrile-labeled amino acid, p-cyanophenylalanine, is introduced near the active site of the semisynthetic enzyme ribonuclease S to serve as a probe of protein dynamics and fluctuations.

An efficient strategy for producing RNA‐free Nucleocapsid protein of SARS‐CoV‐2 for biochemical and structural investigations

open access: yesFEBS Open Bio, EarlyView.
Cleavable N‐terminal Thioredoxin fusion enabled soluble expression and purification of otherwise insoluble SARS‐CoV‐2 Nucleocapsid (N) protein. A four‐step purification strategy yielded highly homogeneous, RNA‐free N protein. Binding assays showed high RNA affinity (Kd ~ 28 nm). The study will facilitate high‐resolution structural studies of N protein,

Adenovirus-mediated hPNPase(old-35) gene transfer as a therapeutic strategy for neuroblastoma [PDF]

open access: yes, 2009
Current treatment options for neuroblastoma fail to eradicate the disease in the majority of high-risk patients, clearly mandating development of innovative therapeutic strategies. Gene therapy represents a promising approach for reversing the neoplastic

Analysis of the regulation of undecaprenyl diphosphate dephosphorylation in Escherichia coli

open access: yesFEBS Open Bio, EarlyView.
BacA, PgpB, and YbjG phosphatases are involved in undecaprenyl phosphate (C55P) synthesis in Escherichia coli. We analyzed the lipid contents and the gene expression in the gene‐disruption strains. Undecaprenyl diphosphate (C55PP) level increased in the bacA, ybjG double‐disruption strain, but C55P levels were similar in all strains.
