Analysis of TP53 gene transcriptional varians in human leucemic cells
Vlahová, Veronika ; Mgr.Diana Grochová, Ph.D. (referee) ; Malčíková,, Jitka (advisor)
The theoretical part of the thesis summarizes general information about the human TP53 gene and p53 protein, which is encoded by this gene. There is also dealt with the transcriptional variants - p53 isoforms. The experimental part is focused on the detection of isoform p53 and its shorter, yet undescribed form. The starting material is peripheral blood of patients from University Hospital Brno, from which RNA was isolated. Subsequently, RNA was transcribed by reverse transcription into cDNA which was amplified by polymerase chain reaction (PCR). Experimental measurements demonstrate that p53 occurs in all the B-lymphocytes of patients with chronic lymphocytic leukemia. It also demonstrats the existence of a shorter form of p53.

Specifická izolace microRNA pomocí magnetizovatelných mikročástic
Vlahová, Veronika
MicroRNAs are small non-coding RNA molecules with length of about 22 nt. These molecules participate on regulation of gene expression at the post-transcriptional level. They represent the largest group of regulators in the cell and therefore are also involved in all key processes such as proliferation, differentiation or apoptosis. Moreover, they participate in tumor transformation. These small molecules have a great potential to be diagnostic markers or assist in the treatment and prevention of diseases. This research was focused on the development of isolation method using magnetic particles with subsequent electrochemical detection of microRNA. Optimization steps were performed and then the entire method was successfully applied to real samples of HEK293 cells expressing increased levels of miR-124. The developed method proved to be sufficiently specific and applicable to the analysis of microRNA.
