About

Led by Prof. Dr. Kathrin Leppek, the Leppek Lab is located at Biomedical Center II (BMZ II) at the University Hospital Bonn. We are part of the Institute of Clinical Chemistry and Clinical Pharmacology within the Faculty of Medicine of the Rheinische Friedrich-Wilhelms-University Bonn.

Lab Culture

I am committed to scientific training of the next generation of scientists. I am determined to pursuing rigorous, innovative research, and to making fundamental discoveries. Our team is collaborative and inclusive. Everyone is welcome and offered the opportunity to learn and grow to their full potential. I want to build a supportive lab environment and community that will foster scientific development and collaboration. I am convinced that rigorous and reproducible discoveries are at the core of the scientific endeavor. Our lab is creating a welcoming, respectful, inclusive and collaborative lab environment with a clear mission: innovative science, training, and mentorship. We try to foster creativity and learning while promoting the personal and professional growth of scientists at all experience levels. We value:

Innovation through diversity
Diversity of perspectives fosters creativity and innovation. Our lab welcomes trainees from various educational levels and scientific backgrounds.

Collaboration
We discover new RNA biology and develop new RNA tools using unbiased interdisciplinary strategies. We are happy to share our tools and explore new scientific areas with local and international collaborations.

Commitment to training & mentorship
We train our mentees to be creative scientists, effective communicators, and respectful mentors. We offer individualized and supportive mentorship.

Community & outreach
Science needs to become more accessible to the general public. We aim to spark curiosity and inspire the next generation of scientists through outreach projects.

Teaching

Elective Module MSc: Brown Fat RNA Dynamics

Course Contents

Adipose tissue, commonly known as fat tissue, is a specialized type of connective tissue primarily composed of adipocytes, which are cells specialized for storing energy in the form of fat. In this module, the students will be able to name the morphological differences of brown and white adipose tissue and to recognize them in Hematoxylin and eosin (H&E) staining, as well as fluorescently labelled tissue. The students will learn the ViewRNA technology, use ViewRNA, understand the translational regulation of brown fat regulators and learn how to study translation regulation using various reporter assays.

The following content will be covered by the practical course:

  • Localization-specific detection of mRNAs with fluorescent probes within mouse tissue sections (ViewRNA)
  • ViewRNA of mRNA targets in cold-exposed vs. control murine brown adipose tissue
  • Comparison of mRNA to protein levels with immunofluorescence microscopy
  • High-resolution microscopy of brown adipose tissue
  • Luciferase mRNA reporter assays and RT-qPCR analysis for translation dynamics of adipose-relevant target genes in murine endothelial cell lines
  • Fluorescent circular RNA reporter assays to study IRES-mediated translation regulation
  • Integrative quantification and analysis of primary data and figure design

This is the research field we will explore in this course together with the Wilhelm-Jüngling Lab at the UKB.

Teaching Goals

In this course, the students will get an overview about state-of-the-art techniques to study adipose tissue and RNA translation dynamics in well-defined models (mammalian tissues and cell lines). Key competences include performing experiments, data analysis, presentation of results, and critically discussing experimental outcomes in English.

Lab Rotations

MSc students who are interested in our research can apply for a lab rotation. Rotation students shadow one of our PhD students investigating transcript-specific translation regulation in the immune response. During the rotation, the student will learn how mRNA translation is regulated in a gene-specific manner in immune cells, develop an understanding of the principles of reporter assays and experimental design, analysis and interpretation. The student will also get hands-on training in advanced RNA technologies. Key competences include planning and conducting experiments, data analysis, presentation of results, and critically discussing experimental outcomes in English.
