Instructions: Given a passage, construct a question on the basis of the information present in the passage. Construct the question in such a way that (i) it is unambiguous, (ii) it is answerable from the passage, (iii) its answer is unique (iv) it answer uses text phrases from the passage. Avoid creating questions that (i) can't be answered correctly without actually understanding the passage and (ii) uses the same words or phrases given in the passage.
Input: The striated muscle costamere, a multiprotein complex at the boundary between the sarcomere and the sarcolemma, plays an integral role in maintaining striated muscle structure and function. Multiple costamere-associated proteins, such as integrins and integrin-interacting proteins, have been identified and shown to play an increasingly important role in the pathogenesis of human cardiomyopathy. Kindlin-2 is an adaptor protein that binds to the integrin cytoplasmic tail to promote integrin activation. Genetic deficiency of Kindlin-2 results in embryonic lethality, and knockdown of the Kindlin-2 homolog in Caenorhabditis elegans and Danio rerio suggests that it has an essential role in integrin function and normal muscle structure and function. The precise role of Kindlin-2 in the mammalian cardiac myocyte remains to be determined.', 'The current studies were designed to investigate the role of Kindlin-2 in the mammalian heart. We generated a series of cardiac myocyte-specific Kindlin-2 knockout mice with excision of the Kindlin-2 gene in either developing or adult cardiac myocytes. We found that mice lacking Kindlin-2 in the early developing heart are embryonic lethal. We demonstrate that deletion of Kindlin-2 at late gestation or in adult cardiac myocytes resulted in heart failure and premature death, which were associated with enlargement of the heart and extensive fibrosis. In addition, integrin 1D protein expression was significantly downregulated in the adult heart.
Output:
Does postnatal Loss of Kindlin-2 lead to Progressive Heart Failure?
