Welcome to the STOP lab

Genomic Regulation – focusing on Gene Ends

Our lab’s aim is to integrate different levels of gene expression regulation – chromatin, transcription and RNA processing – focusing on gene ends.

We want to understand the basic mechanisms of when and how transcription stops (terminates), but also how perturbed termination contributes to disease. Premature termination, called also transcription attenuation, is particularly relevant in the pathological context. Premature termination was known to be an important regulatory mechanism in bacteria and yeast, but overlooked in humans and animals in general. We and others have recently shown that this phenomenon is a very abundant genomic event in metazoa. It has also medical implications, particularly in cancer.

Our main approaches are based on NGS (genomics and nascent transcriptomics), combined with molecular biology, biochemistry and proteomics.  The lab’s experimental workhorse are mammalian cell culture models of cancer and neuronal differentiation. We use both experimental and computational approaches. 

We are recruiting – please get in touch if you are enthusiastic about genomic regulation and searching for an exciting PhD or postdoc position!

Our team


Kinga Kamieniarz-Gdula, PhD, DSc

Group leader

kinga.kamieniarz-gdula [at] amu.edu.pl

Kinga is an experimental and computational biologist. She finished her undergraduate studies at Adam Mickiewicz University in Poznań. She then did her PhD as well as a short postdoc in the field of Chromatin and Epigenetics with Rob Schneider at the Max-Planck-Institute in Freiburg, Germany. After that she moved to the University of Oxford to join Nick Proudfoot’s lab, supported by a Marie Skłodowska-Curie Fellowship. In Oxford, Kinga started studying the links between transcription termination and RNA processing, and became fascinated by gene ends.
After 13 successful years abroad, Kinga recently returned to Poznań to set up her own research group. Her team is generously supported by NAWA Polish Returns and NCN SONATA BIS grants.
In her spare time Kinga loves hiking in the local forests with her family.

Agata Stępień, PhD, eng.

Agata received her Engineer and MSc degree in biotechnology from the University of Agriculture in Krakow. She then moved to Poznan for her PhD, and worked in the group of Prof. Jarmolowski and Prof. Szweykowska-Kulinska at Adam Mickiewicz University. Her PhD research was focused on the characterization of the crosstalk between the spliceosome and the microprocessor in plants by molecular biology, microscopic and biochemical techniques. After graduating in 2017, Agata got her first Postdoc position in K. Dorota Raczynska’s group to study the role of U7 snRNA in human cells. In 2019, Agata joined STOP lab to investigate transcription termination changes during cancer progression.
