to define signature mRNA patterns genet.

[Ka-Lena]

Пожалуйста, помогите перевести.

Выражение встречается в следующем контексте: Recent studies have suggested that it is possible to examine the gene expression profile from tissue samples as small as a renal biopsy specimen. Because there are few quantitative, histologic predictors of disease progression, these molecular techniques have the capacity to define signature mRNA patterns that could better guide therapy, either by identifying patients who are likely to respond or be resistant to existing therapies or by identifying new therapeutic targets.
