Quantitative detection of methylation of FHIT
and BRCA1 promoters in the serum of ductal breast cancer patients.

50 CpG island methylation of the FHIT
gene is correlated with loss of gene expression in lung and breast cancer.
There were no statistically significant differences between the expression of gastric cancer cell proteins: FHIT
, p-catenin, y-catenin, cathepsin B, EGF, HER-2, MMP-9, MCM-2, Bak, Bax, BclXL, p53, FasL and Procaspase 3, depending on the classification according to Lauren (Table 2).
Methods: Truncated structures of FHIT
were screened to reveal critical sections engaging in FHIT
4] Genes: E6, E6 transforming protein [human papillomavirus 18]; E2, E2 regulatory protein [human papillomavirus]; E7, E7 transforming protein [human papillomavirus]; TP53, tumor protein p53; IFNG, interferon, gamma; TMC6 (previously known as EVER1), transmembrane channel-like 6; TMC8 (previously known as EVER2), transmembrane channel-like 8; DAPK, death-associated protein kinase 1; CDH1, cadherin 1, type 1, E-cadherin (epithelial); RASSF1, Ras association (RalGDS/AF-6) domain family member 1; CDKN2A, cyclin-dependent kinase inhibitor 2A; FHIT

Other topics considered are cell cycle control proteins in human breast cancer, primary roles of the retinoblast protein family in cell cycle regulation, and FHIT
and cancer initiating cells.
18), y algunos cambios caracteristicos como: la delecion homocigota de la glutation-transferasa-S (GSTM-1), diferentes polimorfismos en los genes de reparacion XRCC1 y ERCC2, las mutaciones en el TP53 y la perdida alelica del gen FHIT
They analyzed the behavior of two tumor-suppressing genes, p16 and FHIT
, that are silenced or damaged in the early stages of cancer development, and tracked whether the genes were silenced by methylation, the attachment of a chemical methyl group to an atom or molecule, which in this case, eventually leads to the function of a gene shutting down.
For example, they found strong correlations in the inhibition (promoter methylation) of tumor suppressor genes pl6 and FHIT
in 1,774 tissue samples.
