A Cluster of Evolutionarily Recent KRAB Zinc Finger Proteins Protects Cancer Cells from Replicative Stress–Induced Inflammation

Didier Trono, Priscilla Turelli, Sandra Eloise Kjeldsen, Evaristo Jose Planet Letschert, Filipe Amândio Brandão Sanches Vong Martins, Florian Huber, Cyril David Son-Tuyên Pulver, Olga Marie Louise Rosspopoff, Romain Forey, Joana Carlevaro Fita

Heterochromatin loss and genetic instability enhance cancer progression by favoring clonal diversity, yet uncontrolled replicative stress leads to mitotic catastrophe and inflammatory responses that promote immune rejection. KRAB domain-containing zinc fin ...

Synthesis and direct assay of large macrocycle diversities by combinatorial late-stage modification at picomole scale

Gerardo Turcatti, Christian Heinis, Julien Bortoli Chapalay, Jonathan Patrice Vesin, Alessandro Angelini, Manuel Leonardo Merz, Sevan Mleh Habeshian, Mischa Schüttel, Ganesh Kumar Mothukuri, Gontran Sangouard, Cristina Diaz Perlas, Zsolt Bognár

Macrocycles have excellent potential as therapeutics due to their ability to bind challenging targets. However, generating macrocycles against new targets is hindered by a lack of large macrocycle libraries for high-throughput screening. To overcome this, ...

KAP1 facilitates reinstatement of heterochromatin after DNA replication

Didier Trono, Suk Min Jang, Priscilla Turelli, Sandra Eloise Kjeldsen, Julien Léonard Duc, Annamaria Kauzlaric, Andrea Coluccio, Julien Paul André Pontis, Benjamin Rauwel, Geneviève Almouzni

During cell division, maintenance of chromatin features from the parental genome requires their proper establishment on its newly synthetized copy. The loss of epigenetic marks within heterochromatin, typically enriched in repetitive elements, endangers ge ...

Transcription-induced supercoiling explains formation of self-interacting chromatin domains in S-pombe

Yannis Burnier, Julien Dorier, Fabrizio Benedetti, Andrzej Stasiak

The question of how self-interacting chromatin domains in interphase chromosomes are structured and generated dominates current discussions on eukaryotic chromosomes. Numerical simulations using standard polymer models have been helpful in testing the vali ...

Multivalency governs HP1α association dynamics with the silent chromatin state

Beat Fierz, Louise Catherine Bryan, Sinan Kilic, Andreas Linus Bachmann

Multivalent interactions between effector proteins and histone post-translational modifications are an elementary mechanism of dynamic chromatin signalling. Here we elucidate the mechanism how heterochromatin protein 1α (HP1α), a multivalent effector, is e ...

Dma1-dependent degradation of SIN proteins during meiosis in Schizosaccharomyces pombe

Viesturs Simanis, Andrea Krapp

The Schizosaccharomyces pombe septation initiation network (SIN) is required for cytokinesis during vegetative growth and for spore formation during meiosis. Regulation of the SIN during mitosis has been studied extensively, but less is known about its mei ...

Adeno-Associated Virus Activates an Innate Immune Response in Normal Human Cells but Not in Osteosarcoma Cells

Peter Martin Beard

Adeno-associated virus (AAV) is a small, DNA-containing dependovirus with promising potential as a gene delivery vehicle. Given the variety of applications of AAV-based vectors in the treatment of genetic disorders, numerous studies have focused on the imm ...

DNA damage sensors ATM, ATR, DNA-PKcs, and PARP-1 are dispensable for human immunodeficiency virus type 1 integration

Didier Trono, Priscilla Turelli

Integration of a DNA copy of the viral RNA genome is a crucial step in the life cycle of human immunodeficiency virus type 1 (HIV-1) and other retroviruses. While the virally encoded integrase is key to this process, cellular factors yet to be characterize ...

Mitotic hyperphosphorylation of the fission yeast SIN scaffold protein cdc11p is regulated by the protein kinase cdc7p

Viesturs Simanis, Andrea Krapp, Elena Cano

The fission yeast septation initiation network (SIN) triggers the onset of septum formation and cytokinesis. SIN proteins signal from the spindle pole body (SPB), to which they bind in a cell cycle-dependent manner, via the scaffold proteins sid4p and cdc1 ...
