[HTML][HTML] Alternative splicing modulation by G-quadruplexes

I Georgakopoulos-Soares, GE Parada… - Nature …, 2022 - nature.com
Alternative splicing is central to metazoan gene regulation, but the regulatory mechanisms
are incompletely understood. Here, we show that G-quadruplex (G4) motifs are enriched ~3-…

[HTML][HTML] Transcription factor binding site orientation and order are major drivers of gene regulatory activity

I Georgakopoulos-Soares, C Deng, V Agarwal… - Nature …, 2023 - nature.com
The gene regulatory code and grammar remain largely unknown, precluding our ability to link
phenotype to genotype in regulatory sequences. Here, using a massively parallel reporter …

A practical framework and online tool for mutational signature analyses show intertissue variation and driver dependencies

…, G Koh, SE Momen, I Georgakopoulos-Soares… - Nature cancer, 2020 - nature.com
Mutational signatures are patterns of mutations that arise during tumorigenesis. We present
an enhanced, practical framework for mutational signature analyses. Applying these …

[HTML][HTML] Transcription-coupled repair and mismatch repair contribute towards preserving genome integrity at mononucleotide repeat tracts

I Georgakopoulos-Soares, G Koh, SE Momen… - Nature …, 2020 - nature.com
The mechanisms that underpin how insertions or deletions (indels) become fixed in DNA
have primarily been ascribed to replication-related and/or double-strand break (DSB)-related …

[HTML][HTML] EMT factors and metabolic pathways in cancer

I Georgakopoulos-Soares, DV Chartoumpekis… - Frontiers in …, 2020 - frontiersin.org
The epithelial-mesenchymal transition (EMT) represents a biological program during which
epithelial cells lose their cell identity and acquire a mesenchymal phenotype. EMT is …

[PDF][PDF] Characterizing mutational signatures in human cancer cell lines reveals episodic APOBEC mutagenesis

…, F Iorio, JMC Tubio, CC Koh, I Georgakopoulos-Soares… - Cell, 2019 - cell.com
Multiple signatures of somatic mutations have been identified in cancer genomes. Exome
sequences of 1,001 human cancer cell lines and 577 xenografts revealed most common …

Noncanonical secondary structures arising from non-B DNA motifs are determinants of mutagenesis

I Georgakopoulos-Soares, S Morganella… - Genome …, 2018 - genome.cshlp.org
Somatic mutations show variation in density across cancer genomes. Previous studies have
shown that chromatin organization and replication time domains are correlated with, and …

[PDF][PDF] High-throughput characterization of the role of non-B DNA motifs on promoter function

I Georgakopoulos-Soares, J Victorino, GE Parada… - Cell genomics, 2022 - cell.com
Alternative DNA conformations, termed non-B DNA structures, can affect transcription, but
the underlying mechanisms and their functional impact have not been systematically …

[HTML][HTML] The chemotherapeutic drug CX-5461 is a potent mutagen in cultured human cells

…, C Badja, Y Memari, I Georgakopoulos-Soares… - Nature Genetics, 2024 - nature.com
The chemotherapeutic agent CX-5461, or pidnarulex, has been fast-tracked by the United
States Food and Drug Administration for early-stage clinical studies of BRCA1-, BRCA2- and …

[HTML][HTML] Deletion of CTCF sites in the SHH locus alters enhancer–promoter interactions and leads to acheiropodia

…, C Xiong, J Zhao, I Georgakopoulos-Soares… - Nature …, 2021 - nature.com
Acheiropodia, congenital limb truncation, is associated with homozygous deletions in the
LMBR1 gene around ZRS, an enhancer regulating SHH during limb development. How these …
