Structural basis of BAK sequestration by MCL-1 in apoptosis

Apoptosis controls cell fate, ensuring tissue homeostasis and promoting disease when dysregulated. The rate-limiting step in apoptosis is mitochondrial poration by the effector B cell lymphoma 2 (BCL-2) family proteins BAK and BAX, which are activated by i ...

Development of patient-derived lymphomoids with preserved tumor architecture for lymphoma therapy screening

Justine Epiney, Divyanshu Srivastava, Elisa Oricchio, Daniele Tavernari, Albert Santamaria Martinez

The efficacy of anti-cancer therapies depends on the genomic composition of the tumor, its microenvironment, spatial organization, and intra-tumor heterogeneity. B-cell lymphomas are a heterogeneous group of tumors emerging from B-cells at different stages ...

Investigating the effect of inflammation on the progression of B-cell lymphoma dissemination in the sentinel lymph node

Daniel Molina Romero

Lymphomas are a group of heterogeneous blood cancers that arise from lymphocytes. The two primary clinical classifications of lymphomas are Hodgkin's lymphoma (HL), and non-Hodgkin's lymphoma (NHL). In particular, B-cell lymphoma refers to the malignancies ...

Whole-genome doubling drives oncogenic loss of chromatin segregation

Juan Diaz Miyar, Elisa Oricchio, Natalya Katanayeva, Daniele Tavernari, Ruxandra-Andreea Lambuta

Whole-genome doubling (WGD) is a recurrent event in human cancers and it promotes chromosomal instability and acquisition of aneuploidies(1-8). However, the three-dimensional organization of chromatin in WGD cells and its contribution to oncogenic phenotyp ...

The THO complex counteracts TERRA R-loop-mediated telomere fragility in telomerase(+) cells and telomeric recombination in ALT(+) cells

Joachim Lingner, Rita Valador Fernandes

Telomeres are the nucleoprotein structures at the ends of linear chromosomes. Telomeres are transcribed into long non-coding Telomeric Repeat-Containing RNA (TERRA), whose functions rely on its ability to associate with telomeric chromatin. The conserved T ...
