Clinical Significance
Mutations in IKK-α in humans have been linked to lethal fetal malformations. The phenotype of these mutant fetuses is similar to the mouse IKK-α null phenotype, and is characterized by shiny, thickened skin and truncated limbs.
Decreased IKK-α activity has been reported in a large percentage of human squamous cell carcinomas, and restoring IKK-α in mouse models of skin cancer has been shown to have an anti-tumorigenic effect.

Famous quotes containing the word significance:
“The hypothesis I wish to advance is that ... the language of morality is in ... grave disorder.... What we possess, if this is true, are the fragments of a conceptual scheme, parts of which now lack those contexts from which their significance derived. We possess indeed simulacra of morality, we continue to use many of the key expressions. But we have—very largely if not entirely—lost our comprehension, both theoretical and practical, of morality.”
—Alasdair Chalmers MacIntyre (b. 1929)
