eIF3 and eIF4E are very important eukaryotic translation initiation factors. eIF3 is practically involved in every step of translation initiation, eIF4E is important mainly for its ability to bind the cap. Mammalian factor eIF3 consists of thirteen subunits, many subunits have a function apart from translation, such as in apoptosis and mitosis. It was proved that upregulated or downregulated expression of some subunits as well as upregulated expression of eIF4E is linked with different types of tumours and malignancies in human. In the first part of my work, I was examining the amount of transcripts of subunits eIF3a, b, d, e, f, g, h, i and j in cell lines which are used for study of acute lymphoblastic leukaemia. I tried to find if there is a difference in the amount of trancripts between lines or between lines and control line in these subunits. According to experiments and statistical analysis, I proved increased amount of mRNA for eIF3b subunit in control cell line NC-NC in comparison with other used leukaemic cell line except from line NALM6. Other differences were not statistically important. In the second part of my work, I was analysing 3' UTR region of transcripts of eIF4E1 and utilising of polyadenylation signals in this trancript. I used the leukeamic cell lines again. The experiments clearly...
