Research group Long-range gene regulation and 3D chromatin organization in Glioblastoma.

Wallenberg Molecular Medicine Fellow: Cancer

The group is mainly focused on how the reprogramming of regulatory regions and topological changes in 3D chromatin organization determine gene dysregulation in glioblastoma, and how this subsequently contributes to malignancy, heterogeneity and invasiveness.

Research interest

Glioblastoma is the most lethal and aggressive, but also the most common, of all primary brain tumors. Most genetic variants that predispose to cancer are located in non-coding regions enriched in putative enhancers, whose systematic rearrangements have a high impact on gene expression in cancer. Despite the number of susceptibility loci identified in glioblastoma, a functional understanding of how the non-coding regulatory genome contributes to the pathogenesis is missing.

Our research is focused in understanding how the reprogramming of regulatory regions and topological changes in 3D chromatin organization determine gene dysregulation in glioblastoma. We bring knowledge from different biological and technical backgrounds into the glioblastoma field, employing next generation sequencing approaches, genome editing and live-cell imaging in both glioblastoma mouse models and patient-derived glioblastoma cell lines.

The lab is currently studying the 3D chromatin organization of the glioblastoma genome and its interplay with the epigenetic and transcriptional landscapes, and how this interplay influences malignancy and integrates cues from the neurons in the tumor microenvironment to orchestrate gene expression in glioblastoma.

Strengths in the lab

In the lab we combine state-of-the-art approaches in different fields. We have a strong expertise in "omics"-based approaches (e.g HiChIP, 4C-seq, HiC, ChIP-seq, ATAC-seq, RNA-seq), bioinformatics, CRISPR-Cas9-based (epi-)genome editing, mouse genetics, mouse models of cancer and live-cell imaging. We apply these various technologies to the study of 3D chromatin organization and long-range gene regulation in the field of glioblastoma, using both mouse models and patient-derived glioblastoma cell lines.
