Two-faced activity of RNF8: What "twists" it from a genome guardian to a cancer facilitator?

Published: October 2016

The RING finger protein 8 (RNF8)-induced ubiquitination signaling cascade promotes DNA repair and maintains genomic stability. Our study reveals an unexpected action of RNF8 in promoting cancer metastasis, cancer stem cell formation, and chemoresistance through the regulation of TWIST lysine 63 (K63)-linked ubiquitination, suggesting that RNF8 may serve as a new cancer prognosis marker and therapeutic target.

Immune checkpoint inhibitors have shaped the landscape of cancer treatment. However, many patients either do not respond or suffer from later progression. Numerous proteins can control immune system activity, including multiple tumor necrosis factor (TNF) superfamily (TNFSF) and TNF receptor superfamily (TNFRSF) members; these proteins play a complex role in regulating cell survival and death, cellular differentiation, and immune system activity.

Living systems utilize sophisticated biochemical regulators and various signal transduction mechanisms to program bio-molecular assemblies and their associated functions. Creating synthetic assemblies that can replicate the functional and signal-responsive properties of these regulators, while also interfacing with biomolecules, holds significant interest within the realms of supramolecular chemistry and chemical biology. This pursuit not only aids in understanding the fundamental design principles of life but also introduces novel capabilities that contribute to the advancements in medical and therapeutic research.

Article Synopsis
  • The study investigates inherited genetic defects in blood coagulation, focusing on the coagulation factor V gene and how mutations affect clinical phenotypes, which can lead to either bleeding or thrombosis disorders.
  • A family case study revealed a premature stop-codon mutation in the coagulation factor V gene that resulted in very low FV levels in the affected male, who experienced severe bleeding, while his father had a history of severe thrombosis.
  • Advanced coagulation tests indicated that the family members exhibited varying responses to activated protein C, providing insights into their contrasting clinical outcomes despite shared genetic backgrounds.

Article Synopsis
  • Iron homeostasis is crucial for organisms as it facilitates essential biochemical functions but can be toxic in excess, which is regulated by the protein Fur in bacteria.
  • The HpFur protein in Helicobacter pylori uniquely acts as a transcriptional commutator, with its apo- and holo- forms serving as different repressors that bind DNA in distinct ways for various target genes.
  • The study proposes a comprehensive redefinition of holo-HpFur regulatory targets using RNA-seq and ChIP-seq data, uncovering new coding sequences and non-coding RNAs influenced by iron availability, thereby enriching the understanding of this protein's regulatory roles.
