Molecular insights into RNA and DNA helicase evolution from the determinants of specificity for a DEAD-box RNA helicase

open access: yeseLife, 2014
How different helicase families with a conserved catalytic ‘helicase core’ evolved to function on varied RNA and DNA substrates by diverse mechanisms remains unclear.

Recognition of two distinct elements in the RNA substrate by the RNA-binding domain of the T. thermophilus DEAD box helicase Hera [PDF]

open access: yes, 2017
DEAD box helicases catalyze the ATP-dependent destabilization of RNA duplexes. Whereas duplex separation is mediated by the helicase core shared by all members of the family, flanking domains often contribute to binding of the RNA substrate.

A multilevel perspective on MSH6‐associated Lynch syndrome: Integrating molecular, biological, and clinical insights

open access: yesInternational Journal of Cancer, EarlyView.
Abstract Lynch syndrome (LS) is the most common hereditary colorectal cancer syndrome, caused by a germline pathogenic variant in one of the mismatch repair (MMR) genes. Among these, MSH6‐associated LS represents a distinct subtype with unique molecular and clinical characteristics.

The T‐Cell Response Mechanism in Human Papillomavirus‐Associated Cervical Cancer and New Strategies for Immunotherapy

open access: yesiNew Medicine, EarlyView.
ABSTRACT Human papillomavirus (HPV) is a double‐stranded DNA virus that infects human skin and mucosal tissues exclusively. The German scientist Harald zur Hausen was awarded the 2008 Nobel Prize in Physiology or Medicine for his discovery of the link between HPV infection and cervical cancer.

N6‐Methyladenosine (m6A) in Liver Disease: Pathogenic Mechanisms and Therapeutic Potential

open access: yesiNew Medicine, EarlyView.
ABSTRACT Accumulating evidence highlights the critical role of epigenetic modifications, particularly N6‐methyladenosine (m6A), in liver disease. As the most abundant RNA modification in eukaryotic cells, m6A is dynamically regulated by multicomponent m6A methyltransferases (e.g., METTL3 and METTL14), demethylases (FTO and ALKBH5), and m6A‐binding ...

Hepatitis C virus NS3 helicase contributes to (−) strand RNA synthesis

open access: yesNature Communications
Many positive strand RNA viruses encode helicases, but their distinct functions in viral replication cycles is poorly understood. Here, we identify a mutation in the helicase domain of HCV non-structural protein 3 (NS3h), D1467G, which specifically ...

Long non-coding RNA SENCR is a positive regulator of ETV2 [PDF]

open access: yes, 2017
Department of Biological SciencesAlthough long non-coding RNAs (lncRNAs) have emerged as novel regulator of cell fate and gene expression, the regulation of vascular specific transcription factor by lncRNA in generation of induced endothelial cells ...

RNA helicases [PDF]

open access: yesRNA Biology, 2013
Similar to proteins, RNA molecules must fold into the correct conformation and associate with protein complexes in order to be functional within a cell. RNA helicases rearrange RNA secondary structure and RNA-protein interactions in an ATP-dependent reaction, performing crucial functions in all aspects of RNA metabolism.

Oncogenic KRAS Rewires Stress Granule Dynamics: Mechanisms and Therapeutic Opportunities

open access: yesThe Kaohsiung Journal of Medical Sciences, EarlyView.
ABSTRACT Stress granules (SGs) are dynamic, membrane‐less structures that form in response to various cellular stresses, including metabolic, oxidative, and therapeutic challenges. They function as adaptive hubs and reorganize protein synthesis and signaling networks to help cells survive under stress. In cancer, these condensates are often hijacked to
