Protocol: A Multiplexed Reporter Assay to Study Effects of Chromatin Context on DNA Double-Strand Break Repair

Frontiers in Genetics, 2022
DNA double-strand breaks (DSBs) can be repaired through various pathways. Understanding how these pathways are regulated is of great interest for cancer research and optimization of gene editing.

SWI/SNF catalytic subunits’ switch drives resistance to EZH2 inhibitors in ARID1A-mutated cells

Nature Communications, 2018
The mechanism of resistance to EZH2 inhibitors in cancers with inactivating SWI/SNF mutations is unknown. Here, the authors demonstrate that the switch of the SWI/SNF catalytic subunits from SMARCA4 to SMARCA2 drives resistance to EZH2 inhibitors in ...

TNF-alpha inhibition ameliorates HDV-induced liver damage in a mouse model of acute severe infection

JHEP Reports, 2020
Background & Aims: HDV infection induces the most severe form of human viral hepatitis. However, the specific reasons for the severity of the disease remain unknown.

The human lncRNA LINC-PINT inhibits tumor cell invasion through a highly conserved sequence element

Genome Biology, 2017
Background It is now obvious that the majority of cellular transcripts do not code for proteins, and a significant subset of them are long non-coding RNAs (lncRNAs).

Multi-locus CRISPRi targeting with a single truncated guide RNA

Nature Communications
A critical goal in functional genomics is evaluating which non-coding elements contribute to gene expression, cellular function, and disease. Functional characterization remains a challenge due to the abundance and complexity of candidate elements. Here,

Structural basis underlying viral hijacking of a histone chaperone complex

Nature Communications, 2016
The Epstein-Barr virus tegument protein BNRF1 is required for the establishment of selective viral gene expression during latency and interacts with the histone chaperone DAXX.

Enteropathogenic E. coli shows delayed attachment and host response in human jejunum organoid‐derived monolayers compared to HeLa cells

FEBS Letters, EarlyView.
Enteropathogenic E. coli (EPEC) infects the human intestinal epithelium, resulting in severe illness and diarrhoea. In this study, we compared the infection of cancer‐derived cell lines with human organoid‐derived models of the small intestine. We observed a delayed in attachment, inflammation and cell death on primary cells, indicating that host ...

TENT2, TUT4, and TUT7 selectively regulate miRNA sequence and abundance

Nature Communications, 2022
The authors reveal insights into miRNA tailing specificity of TENTs and their effect on miRNA levels by combinatory KOs of TENT2, TUT4 and TUT7. They show uridylation is linked to TENT2 and identify non-redundant functions between TUT4 and TUT7.

Organoids in pediatric cancer research

FEBS Letters, EarlyView.
Organoid technology has revolutionized cancer research, yet its application in pediatric oncology remains limited. Recent advances have enabled the development of pediatric tumor organoids, offering new insights into disease biology, treatment response, and interactions with the tumor microenvironment.

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, EarlyView.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
