Methylation Sequencing for Brain Tumors
As a central component of epigenetics, DNA methylation is critical for maintaining normal cell function, embryonic development and various physiological processes. Aberrations in DNA methylation play a significant role in tumorigenesis and metastasis. Alfa Cytology offers comprehensive genome-wide DNA methylation detection and analysis to investigate the intricacies of brain tumor progression, metastasis and recurrence, aiming to promote the development of innovative anti-brain tumor strategies.
Methylation Sequencing in Brain Tumors
DNA methylation is an important epigenetic modification that governs gene expression and genome stability. Dysregulation of DNA methylation is intricately related to a variety of diseases such as brain tumors. The demethylation of extensive genomic regions and the hypermethylation of CpG islands are recognized as cancer cell hallmarks. Therefore, DNA methylation signature-based analysis has become a vital tool in brain tumor research. With the evolution of next-generation sequencing, diverse methodologies have been introduced to scrutinize DNA methylation abnormalities involved in brain tumors.
