Spatial Transcriptomics of TNBC tumours and corresponding lymph node metastasis reveals immune hubs driven by TNF/NF-κB signalling of TMSB4X and CD74 expressing cells.

Adrian Perdyan, Urszula Ławrynowicz, Maciej Jaśkiewicz, Anna Kostecka, Katarzyna Chojnowska, Mikołaj Koszyński, Marcin Jąkalski, Michał Bieńkowski, Natalia H. Filipowicz, Agnieszka Misztak, Tomasz Nowikiewicz, Łukasz Szylberg, Marta Drzewiecka, Arkadiusz Piotrowski, Jakub Mieczkowski

The paper uses spatial transcriptomics to identify immune hubs in TNBC lymph node metastases driven by TMSB4X and CD74, revealing spatially expanded inflammatory networks and myeloid-endothelial signaling.

Beyond Tumors: Reduced survival linked to pathogenic PIK3CA and TP53 post-zygotic variants in the uninvolved breast tissue of recurrent cancer patients

Maria Andreou, Katarzyna Chojnowska, Natalia H. Filipowicz, Monika Horbacz, Piotr Madanecki, Katarzyna Duzowska, Urszula Ławrynowicz, Hanna Davies, Bożena Bruhn‐Olszewska, Mikołaj Koszyński, Kinga Drężek-Chyła, Maciej Jaśkiewicz, Marcin Jąkalski, Anna Kostecka, Marta Drzewiecka, , Arkadiusz Piotrowski

The paper identifies pathogenic post-zygotic variants in normal breast tissue of poor-prognosis cancer patients, linking them to reduced survival and disease recurrence.
