Shape based indexing for faster search of RNA family databases

open access: yes, 2008
Janssen S, Reeder J, Giegerich R. Shape based indexing for faster search of RNA family databases. BMC Bioinformatics. 2008;9(1):131.Background: Most non-coding RNA families exert their function by means of a conserved, common secondary structure.

Role of the central cations in the mechanical unfolding of DNA and RNA G-quadruplexes. [PDF]

open access: yes, 2015
Cations are known to mediate diverse interactions in nucleic acids duplexes but they are critical in the arrangement of four-stranded structures. Here, we use all-atom molecular dynamics simulations with explicit solvent to analyse the mechanical ...

Interconnections between m 6 A RNA modification, RNA structure, and protein–RNA complex assembly

open access: yesLife Science Alliance
This review summarizes current knowledge and future directions on the mechanisms that govern the interplay between m 6 A RNA modification, RNA folding, and protein–RNA interactions, focusing on the mechanisms and available quantitative information ...

Nanopore electric snapshots of an RNA tertiary folding pathway

open access: yesNature Communications, 2017
While RNA folding is critical for its function, study of this process is challenging. Here, the authors combine nanopore single-molecule manipulation with theoretical analysis to follow the folding of an RNA pseudoknot, monitoring the intermediate states

RNA folding and ribosome assembly [PDF]

open access: yesCurrent Opinion in Chemical Biology, 2008
Ribosome synthesis is a tightly regulated process that is crucial for cell survival. Chemical footprinting, mass spectrometry, and cryo-electron microscopy are revealing how these complex cellular machines are assembled. Rapid folding of the rRNA provides a platform for protein-induced assembly of the bacterial 30S ribosome.

Interrogating the immune landscape of microsatellite stable RAS‐mutated colon cancer

open access: yesMolecular Oncology, EarlyView.
COLOSSUS project RAS‐mutated MSS colon cancer study explored transcriptomics and immune cell density by immunohistochemistry (IHC), Immunoscore (IS), ISIC/TuLIS scores, mutation counts, and detected different prevalences but similar microenvironment composition across immune markers with clinical relevance for future immunotherapy combination ...

Live cell imaging of single RNA molecules with fluorogenic Mango II arrays

open access: yesNature Communications, 2020
Fluorogenic RNA aptamers have been used for RNA imaging, but folding and fluorescence stability often limited their use in high resolution applications.

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

open access: yesMolecular 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.

Structure of a rare non-standard sequence k-turn bound by L7Ae protein [PDF]

open access: yes, 2014
Kt-23 from Thelohania solenopsae is a rare RNA kink turn (k-turn) where an adenine replaces the normal guanine at the 2n position. L7Ae is a member of a strongly conserved family of proteins that bind a range of k-turn structures in the ribosome, box C/D

Keratin 19 as a prognostic marker and contributing factor of metastasis and chemoresistance in high‐grade serous ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Keratin 19 (KRT19) is overexpressed in high‐grade serous ovarian cancer with high levels of Kallikrein‐related peptidases (KLK) 4–7 and is associated with poor survival. In vivo analyses demonstrate that elevated KRT19 increases peritoneal tumour burden.
