Antisense technology provides a tool with which to dissect the components of the stress response. There are two known endogenous sets of protective proteins, the heat shock proteins (Hsps) and the antioxidants, such as superoxide dismutase;1–4 components of both sets of proteins have been found to be induced in different stress settings, such as heat shock and ischemia. At the current time our ability to manipulate expression of these important genes is limited. The known stimuli induce multiple different stress response genes, which curtails our ability to understand the function of each of these genes. One approach to this question has been overexpression of individual Hsp, such as Hsp72 and Hsp27, each of which has now been shown to protect against injury such as ischemia, hypoxia, or heat.5–10 However, overexpression prior to injury does not clarify the role of a given protein in the endogenous stress response. Understanding this role increases our comprehension of protein function and also provides insight into the mechanisms of injury. Antisense technology permits selective inhibition of single genes. Such an approach allows the analysis of the contribution of individual heat shock proteins and antioxidant genes to cardiac protection.
