Example sentences for: methyltransferase
How can you use “methyltransferase” in a sentence? Here are some example sentences to help you improve your vocabulary:
Genomic DNA was treated with sodium bisulphite as previously described [ 46 ] . Placental DNA treated in vitro with Sss I methyltransferase (New England Biolabs, Beverly, MA) and similarly treated normal lymphocyte DNA were used as controls for methylated and unmethylated templates, respectively.
MGMT gene encodes O(6)-methylguanine-DNA methyltransferase and this enzyme effectively removes DNA adducts formed by alkylating agents [ 33 ] . Epigenetic gene silencing of MGMT confers enhanced sensitivity to alkylating-based chemotherapy, and lack of methylation associates with failure to respond to chemotherapy [ 34 35 ] . On the contrary, all patients that had MGMT promoter methylation were dead within 21 months of initial diagnosis, which predicts a poor prognosis.
Their first candidate was an essential enzyme, a methyltransferase called CcrM, that prevents a particular piece of DNA from being expressed in a cell by tagging it with a methyl group.
3 region to which RASSF1A maps undergoes deletions in many solid tumor types, including GCTs [ 9 ] . RASSF1A encodes a splice variant of human RAS effector homologue, which interacts with the XPA protein and functions as a negative regulator of cell growth [ 16 17 ] . RASSF1A has been shown to be inactivated by promoter methylation in a variety of tumor types [ 16 17 18 19 ] . The 17q21 and 17p13 regions, to which BRCA1 and HIC1 map, respectively, also have been characterized by high frequency of LOH in GCT [ 9 ] . The BRCA 1 gene plays critical roles in DNA repair and recombination, cell cycle checkpoint control, and transcription and has been shown to be hypermethylated in breast-ovarian cancer [ 4 ] . The HIC1 gene is also often hypermethylated in many human cancers [ 20 21 22 ] . The DNA repair gene MGMT encodes O(6)-methylguanine-DNA methyltransferase and this enzyme effectively removes DNA adducts formed by alkylating agents [ 23 ] . Epigenetic inactivation of the MGMT gene was reported in a wide variety of cancers [ 24 25 ] . Also, a low frequency of methylation of the APC , RARB , and FHIT genes was detected in NSGCTs.
Although the three capping reactions are universal in eukaryotes, there is a surprising diversity in the genetic organization of the capping enzymes as well as a complete divergence in the structure and catalytic mechanism of the RNA triphosphatase component in "lower" versus "higher" eukaryotic species [ 1 ] . Metazoans and plants have a two-component capping system consisting of a bifunctional triphosphatase-guanylyltransferase polypeptide and a separate methyltransferase polypeptide, whereas fungi contain a three-component system consisting of separate triphosphatase, guanylyltransferase, and methyltransferase gene products.
