Annotation -
The course is composed of the theoretical and the practical parts. Pivotal part of the course is dedicated to qPCR
and work with RNA. The most common experimental approaches for detection and quantification of gene
expression in its different phases will be demonstrated on one gene model.
The course is intended for cell and molecular biology MSc. and PhD. students, but it is also suitable for those
interested in gene expression determination methods from a wide variety of biological sciences. The course is organized as 3-day-turnus and is also accessible to english-speaking students.

Syllabus -

Principles of the demonstrated methods, their advantages and limitations are explained in the theoretical part of the course. Experimental design, data evaluation and results interpretation will be also discussed.

In the practical part, we employ model gene reporter under the control of  an inducible promoter.

Tasks:

1/ Principles of the work with RNA (preparation of solutions, disposables and other equipment). Total RNA isolation, concentration determination, RNA quality analysis using RNA denaturing agarose electrophoresis, DNaseI treatment, cDNA synthesis.

2/ RT PCR and qPCR approach comparison, absolute and relative quantification.

3/ Gene copy number determination by qPCR (data evaluation).

4/ Western blot

5/ Evaluation of inducible promoter activity by luciferase activity measurement and by cell growth determination.

Learning outcomes -

Knowledge
After successful completion of the course, the student defines fundamental concepts
related to gene expression and describes the individual levels of its regulation in
eukaryotic cells. The student explains the principles of methods used for the analysis of
gene expression at the level of phenotype, RNA, and protein. The student describes the
principles of quantitative PCR, reverse transcription, and relative quantification of gene
expression. The student explains the principles of reporter genes and their application in
the study of transcriptional regulation. The student identifies major sources of
experimental and systematic errors in gene expression analysis and describes the
relationships between promoter activity, transcript abundance, and the cellular level of
the corresponding protein.


Skills
After successful completion of the course, the student applies standard laboratory
procedures when working with yeast cultures and genetically modified strains. The
student performs RNA isolation, determines RNA concentration, purity, and integrity, and
evaluates sample suitability for downstream applications. The student performs
enzymatic removal of genomic DNA and reverse transcription of RNA into cDNA. The
student prepares and carries out quantitative PCR experiments, including the
preparation of dilution series, technical replicates, and appropriate controls. The student
evaluates and interprets amplification curves, melting curves, and Ct/Cp values. The
student performs relative quantification of gene expression using a reference gene. The
student applies protein detection methods (Western blot, fluorescence measurement)
and compares protein-level data with RNA-level results. The student analyzes growth
assays on selective media and interprets their relationship to promoter activity.


Competences
After successful completion of the course, the student critically evaluates experimental
data with respect to their biological relevance and technical reliability. The student
compares the advantages and limitations of individual gene expression analysis
methods. The student integrates results obtained at different levels of gene expression
(phenotype, RNA, protein). The student formulates and justifies conclusions based on
experimental data obtained individually and within a working group, and interprets the
results in the broader context of gene expression regulation and experimental design
