Example sentences for: misregulation
How can you use “misregulation” in a sentence? Here are some example sentences to help you improve your vocabulary:
Although complementary sites for both miRNAs are found in the 3' UTRs of several putative nematode targets, these miRNAs are not physically linked in the C. elegans genome and their mutant phenotypes are principally due to misregulation of different transcripts [ 4 5 6 8 ] . The function of these miRNAs has not yet been explicitly demonstrated in other species, but Drosophila let-7 is regulated at the larval-pupal transition by ecdysone [ 49 ] , and all three members of this cluster are present in other insects and in vertebrates, thus implying broadly conserved functions.
Interestingly, mesothelin expression is induced in lung, ovarian, and pancreatic carcinomas where constitutive activation of Wnt signaling is caused by stabilizing mutations in beta-catenin [ 27 28 41 42 43 44 ] . The induction of mesothelin in these carcinomas may be due to misregulation of Wnt signaling as are other targets of the Wnt pathway, c-myc and cyclin D1.
We found a similar phenotype upon overexpression of Hoxd-4 in our transgenic system (Kappen, manuscript in preparation), whereas overexpression of the LIM-homeodomain transcription factor Isl-1 did not cause abnormalities in cartilage but other developmental defects [ 1 9 ] . The observation that cartilage is affected by misregulation of Hoxc-8 and Hoxd-4, but not by a divergent homeobox gene, indicates that the capacity to regulate cartilage differentiation is specific to homeobox genes of the Hox subclass.

This methodology [ 8] has been used by others to define the gene-expression profile of breast tumors [ 9], to subtype diffuse large B-cell lymphomas [ 10] and to identify genes whose expression is associated with mitotic misregulation and human aging [ 11].
