Definitions
- Oligonucleotides to inhibit the expression of human eg5 Oligonucleotides to inhibit the expression of human eg5
- the present invention relates to an oligonucleotide or one of its derivatives having a sequence which corresponds to a specific part of a nucleic acid sequence which encodes human eg5 or a mutated form thereof, and the invention further relates to a method for producing the oligonucleotide and its use.
- a spindle device based on microtubules helps to evenly distribute the duplicated chromosomes among the daughter cells.
- Motor proteins related to kinesin make up part of the forces required to assemble the spindle and split the chromosomes.
- the formation of a bipolar mitotic spindle requires the activity of many different motor proteins.
- One of the human motor proteins related to kinesin is human eg5, which interacts with the mitotic centrosomes and has been shown to be essential for the formation of the bipolar spindle (Blangy et al., Celi (1995) 83, 1159).
- Microinjection of specific anti-human eg5 antibodies blocks centrosome migration and causes cells to stop mitosis.
- Another way to block the formation of a bipolar spindle would be to inhibit eg5 expression.
- One way to specifically inhibit eg5 expression is to use antisense oligonucleotides, which may have been modified to improve their properties (E. Uhimann and A. Peyman, Chemical Reviews 90, 543 (1990); S. Agrawal, TIBTECH 1996, 376).
- Antisense oligonucleotides are believed to bind to specific sequences of the mRNA, which leads to degradation of the mRNA and / or inhibition of protein synthesis.
