Characterization of the Caenorhabditis elegans pop-1 gene
Jakšová, Soňa ; Vacík, Tomáš (advisor) ; Macůrková, Marie (referee)
The TCF/LEF transcriptional factors regulate the target genes of the Wnt signalling pathway - one of the key signalling mechanisms involved in development of multicellular organisms. The TCF/LEF genes produce a number of various protein isoforms, which consequently leads to a great functional diversity of the TCF/LEF proteins. In this diploma project we focused on the Caenorhabditis elegans gene pop-1, the ortholog of the TCF/LEF genes, whose isoforms have not been studied yet. Using the Northern blot analysis we tried to identify alternative isoforms of the pop-1 mRNA in C. elegans. Using quantitative RT-PCR we also analyzed the pop-1 mRNA levels during seven developmental stages of C. elegans. Further, we also determined the expression profile of two important partners of pop-1, the bar-1 and sys-1 genes, whose protein products function as transcriptional co-activators. Key words: canonical Wnt signaling pathway, TCF/LEF transcription factors, Caenorhabditis elegans, pop-1

Characterization of the Caenorhabditis elegans pop-1 gene
Jakšová, Soňa ; Vacík, Tomáš (advisor) ; Cmarko, Dušan (referee)
The human proteom diversity is caused by the ability of a single gene locus to encode more protein isoforms. The TCF/LEF genes produce a broad spectrum of protein variants, which consequently leads to a great functional diversity of the TCF/LEF proteins. The TCF/LEF transcriptional factors regulate the canonical Wnt signaling target genes. In this diploma project we focused on the Caenorhabditis elegans gene pop-1, the ortholog of the TCF/LEF genes. Using the Northern blot analysis we tried to identify alternative isoforms of the pop-1 mRNA in C. elegans. Using quantitative RT-PCR we also analyzed the pop-1 mRNA levels.
