sparser
"Overall, our study demonstrated that a very high percentage of ATL patient samples (74%) presented with FHIT methylation."

sparser
"FHIT methylation was also observed in 13% cases in the adjacent control region."

sparser
"In NSE, there was no promoter methylation of FHIT gene, while in LSCC the rate of it was 24.4% (10/41), and it was related to the tumor pathological grade and lymph node metastasis (P < 0.01)."

sparser
"DNA methylation of RARB, PGR, RASSF1, CDH1, FHIT, ESR1, C1QTNF6 , PTGS2, SOCS3 , MGMT , and LINE1 was analyzed by pyrosequencing and compared with results from the cell lines RT4, T24, HeLa, BEAS-2B, and HepG2."

sparser
"The tumor suppressor Fhit protein is defective or absent in many tumor cells due to methylation, mutation or deletion of the FHIT gene."

sparser
"To further explore the molecular mechanisms between altered TSGs promoter methylation and overexpression of DNMTs protein, we performed a tissue chromatin-immunoprecipitation polymerase chain reaction assay for lung tumors and showed that the methylated FHIT, p16(INK4a) and RARbeta promoters were bound by both DNMT protein and methyl-CpG-binding protein 2."

sparser
"While no FHIT gene promoter methylation was observed in the matched non-cancerous epithelium (NCE) specimens, 24.6% of DTC samples demonstrated methylation in the FHIT promoter region."

sparser
"Thus, Fhit is inactivated at an early stage in the development of ESCC ( xref ); FHIT gene promoter methylation has been linked to cigarette smoking ( xref , xref ), and ESCC may be associated with loss of the Fhit protein expression along with alcohol consumption ( xref , xref )."
