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

, 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

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

Molecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

Comparative analysis of the taxonomic classification criteria for a number of groups of pathogenic DNA and RNA viruses based on genomic data

Вопросы вирусологии
The basis for criteria of the taxonomic classification of DNA and RNA viruses based on data of the genomic sequencing are viewed in this review. The genomic sequences of viruses, which have genome represented by double-stranded DNA (orthopoxviruses as ...

Alternative approach to generate shRNA from cDNA

BioTechniques, 2005
Short hairpin RNA (shRNA) synthesized from vector-based expression is as effective as short interfering RNA (siRNA) synthesized in vitro for suppressing the expression of their corresponding genes.

Identification of Five Putative Yeast RNA Helicase Genes [PDF]

, 1990
The RNA helicase gene family encodes a group of eight homologous proteins that share regions of sequence similarity. This group of evolutionarily conserved proteins presumably all utilize ATP (or some other nucleoside triphosphate) as an energy source ...

Insights into a long life without cancer: The case of the bowhead whale

Molecular Oncology, EarlyView.
Long‐lived, large‐bodied organisms have evolved powerful anticancer mechanisms that preserve cellular and tissue integrity across extended lifespans. A recent study by Firsanov et al. shows that greater genome stability is a key factor underlying the remarkable longevity and cancer resistance of one such species, the bowhead whale.

Identification and sequence determination of a novel double-stranded RNA mycovirus from the entopathogenic fungus Beauveria bassina [PDF]

, 2015
The final publication is available at Springer via https://doi.org/10.1007/s00705-014-2332-8.An isolate of the entomopathogenic fungus Beauveria bassiana was found to contain five double-stranded (ds) RNA elements ranging from 1.5 to more than 3 kbp. The

Proteasome inhibitor, ixazomib prevents topoisomerase‐I degradation and reverses irinotecan resistance in colorectal cancer

Molecular Oncology, EarlyView.
Ixazomib inhibits proteasome‐mediated degradation of topoisomerase I induced by irinotecan, thereby restoring drug sensitivity and promoting tumor cell death in colorectal cancer. Irinotecan, a topoisomerase I (topoI) inhibitor, is widely used for colorectal cancer, but resistance remains a major clinical challenge.

Significantly Improved Recovery of Recombinant Sonchus Yellow Net Rhabdovirus by Expressing the Negative-Strand Genomic RNA

Viruses, 2020
Generation of recombinant negative-stranded RNA viruses (NSVs) from plasmids involves in vivo reconstitution of biologically active nucleocapsids and faces a unique antisense problem where the negative-sense viral genomic RNAs can hybridize to viral ...
