Example sentences for: epigenetic
How can you use “epigenetic” in a sentence? Here are some example sentences to help you improve your vocabulary:
It is informative to compare the epigenetic interactions of the 35S:GFP-COP1 transgenes with those of the PAI (trans)genes, the only other well-characterized system in Arabidopsis [ 12 ] . Both gene sets consist of relatively simple repeat structures and singlet loci, which reside in essentially single-copy environments of Arabidopsis ( [ 27 ] and unpublished observations).
A unique feature of GCTs is their origin from germ cells at a stage in development where they undergo epigenetic reprogramming [ 6 13 ] . The absence of this epigenetic modification in SGCTs is consistent with their GC-like nature as previously noted [ 6 14 ] . On the other hand, the extensive promoter hypermethylation seen in NSGCTs suggests a mechanistic role in their potential for embryonal and extra-embryonal lineage differentiation [ 6 14 ] . Establishment of DNA methylation in the mammalian genome is controlled by at least three DNA methyltransferases (DNMTs), DNMT1 , DNMT3a and DNMT3b [ 15 ] . The role of these DNMTs in differential de novo methylation in SGCT vs.
These data suggest that the competence for trans-silencing may be transferred between non-allelic transgenes, reminiscent of the allelic transfer of epigenetic activity during paramutation.
Epigenetic gene silencing of the MGMT confers enhanced sensitivity to alkylating agents in cancer [ 24 25 ] . Lack of methylation, on the other hand, associates with high-risk of death [ 25 26 ] . It has been suggested that the high-levels of MGMT proteins contribute to a drug-resistant phenotype [ 27 ] . More than 90% of newly diagnosed GCTs and 70-80% of patients who present metastatic disease are cured with cisplatin-based chemotherapy [ 28 ] . However, 20-30% of the patients with metastatic disease exhibit resistance to the cisplatin curative regimen leading to high mortality in this group.
Genetic alterations play an important role in the development of CC [ 4 7 8 ] . Our extensive molecular analyses identified a number of specific genetic changes in invasive CC and its precursor lesions [ 6 14 15 16 17 18 19 ] . However, epigenetic alteration in cervical tumorigenesis is not well characterized [ 12 13 ] . In the present study, we identified an overall methylation in 87.
