The present invention relates to a method of regulating apoptosis. The
method comprises the step of introducing into a cell an RNA construct
comprising a nucleotide sequence which is homologous to mRNA within said
cell. The mRNA within the cell includes genetic information of a gene
element involved in the regulation of apoptosis. The invention also
relates to an siRNA construct having a nucleotide sequence which is
homologous to mRNA transcribed from a gene element involved in the
regulation of apoptosis.
