The invention belongs to the technical field of biological
pharmacy, and provides a group of
esophageal cancer methylation early screening markers and application thereof, the group of markers is any one of ZNF693, MMP14, JAG1, RUNX1 or NOTCH1
gene sequences or
gene segments containing at least one CpG
methylation site, or a combination of any two or more of the ZNF693, MMP14, JAG1, RUNX1 or NOTCH1
gene sequences or gene segments containing at least one CpG
methylation site; the invention also discloses an application of the group of biomarkers in preparation of a detection kit for diagnosing and / or evaluating the methylation degree of
esophageal cancer or an application of the group of biomarkers in screening of drugs for treating and / or relieving
esophageal cancer. According to the method, by quantifying the dynamic change of the methylation level,
cancer patients can be effectively identified, and the risk of missing detection caused by
tumor heterogeneity is reduced; by establishing a high-
throughput and standardized detection process, a precise
molecular typing tool can be provided for early intervention of esophageal
cancer; the limitation that the traditional technology is insufficient in early canceration detection sensitivity and depends on invasive operation is overcome, and the clinical transformation of early screening and early diagnosis can be promoted.
