Spatial and functional arrangement of Ebola virus polymerase inside phase-separated viral factories

open access: yesNature Communications, 2023
Ebola virus (EBOV) infection induces the formation of membrane-less, cytoplasmic compartments termed viral factories, in which multiple viral proteins gather and coordinate viral transcription, replication, and assembly.

Escape from TGF‐β‐induced senescence promotes aggressive hallmarks in epithelial hepatocellular carcinoma cells

open access: yesMolecular Oncology, EarlyView.
Chronic TGF‐β exposure drives epithelial HCC cells from a senescent state to a TGF‐β resistant mesenchymal phenotype. This transition is characterized by the loss of Smad3‐mediated signaling, escape from senescence, enhanced invasiveness and metastatic potential, and upregulation of key resistance modulators such as MARK1 and GRM8, ultimately promoting

Identification of inhibitors of the Salmonella FraB deglycase, a drug target

open access: yesFEBS Open Bio, EarlyView.
A high‐throughput screen was used to identify inhibitors of Salmonella FraB, a drug target. Characterization of top hits (identified after an additional counter screen) revealed that some triazolidines, thiadiazolidines, and triazolothiadiazoles are mixed‐type inhibitors of FraB.

Sp100 colocalizes with HPV replication foci and restricts the productive stage of the infectious cycle. [PDF]

open access: yesPLoS Pathogens, 2017
We have shown previously that Sp100 (a component of the ND10 nuclear body) represses transcription, replication and establishment of incoming human papillomavirus (HPV) DNA in the early stages of infection.

Mapping Hsp104 interactions using cross‐linking mass spectrometry

open access: yesFEBS Open Bio, EarlyView.
This study examines how cross‐linking mass spectrometry can be utilized to analyze ATP‐induced conformational changes in Hsp104 and its interactions with substrates. We developed an analytical pipeline to distinguish between intra‐ and inter‐subunit contacts within the hexameric homo‐oligomer and discovered contacts between Hsp104 and a selected ...

The Cell Cycle Timing of Human Papillomavirus DNA Replication. [PDF]

open access: yesPLoS ONE, 2015
Viruses manipulate the cell cycle of the host cell to optimize conditions for more efficient viral genome replication. One strategy utilized by DNA viruses is to replicate their genomes non-concurrently with the host genome; in this case, the viral ...

Enhancing transporter activity in heterologous expression systems with SAHA: a 2500‐times more potent and odorless alternative to butyrate

open access: yesFEBS Open Bio, EarlyView.
Heterologous expression of membrane transporters in cultured cells is essential for functional characterization, but is sometimes limited by low activity. Our study compares the HDAC inhibitors butyrate, VPA and SAHA to enhance transport activity. We propose to replace butyrate by SAHA: it is equally effective, devoid of repulsive odor, costs less, and

Development of Lentiviral Vectors for HIV-1 Gene Therapy with Vif-Resistant APOBEC3G

open access: yesMolecular Therapy: Nucleic Acids, 2019
Strategies to control HIV-1 replication without antiviral therapy are needed to achieve a functional cure. To exploit the innate antiviral function of restriction factor cytidine deaminase APOBEC3G (A3G), we developed self-activating lentiviral vectors ...

Omicron Spike confers enhanced infectivity and interferon resistance to SARS-CoV-2 in human nasal tissue

open access: yesNature Communications
Omicron emerged following COVID-19 vaccination campaigns, displaced previous SARS-CoV-2 variants of concern worldwide, and gave rise to lineages that continue to spread.

METTL3 knockout accelerates hepatocarcinogenesis via inhibiting endoplasmic reticulum stress response

open access: yesFEBS Open Bio, EarlyView.
Liver‐specific knockout of N6‐methyladenosine (m6A) methyltransferase METTL3 significantly accelerated hepatic tumor initiation under various oncogenic challenges, contrary to the previously reported oncogenic role of METTL3 in liver cancer cell lines or xenograft models. Mechanistically, METTL3 deficiency reduced m6A deposition on Manf transcripts and
