Analysis of Epigenetic Regulation in TME

Within the tumor microenvironment (TME), epigenetic regulation plays a critical role in modulating gene expression patterns and cellular functions, and has been implicated in cancer development and progression. At Alfa Cytology, we are committed to analyzing the epigenetic alterations in different cell types within the TME.

Epigenetic Regulation in TME

Epigenetic regulation refers to modifications in gene expression that are not caused by changes in the DNA sequence but rather by alterations in DNA methylation, histone modifications, and non-coding RNA expression. Epigenetic modifications can have a profound impact on gene expression patterns and cellular behavior. Aberrant epigenetic regulation has been implicated in cancer development and progression, with alterations in DNA methylation and histone modifications being commonly observed in various types of cancer. These changes can lead to abnormal gene expression, silencing of tumor suppressor genes, and activation of oncogenes. In the context of the TME, epigenetic regulation is believed to play a crucial role in shaping the interactions between cancer cells and the surrounding microenvironment. For example, DNA methylation alterations in immune cells can affect their activation and function, influencing the anti-tumor immune response. Similarly, alterations in histone modifications in fibroblasts can modulate their ability to promote tumor growth and invasion.

Analysis of Epigenetic Regulation in TME

We offer a wide range of services designed to unravel the intricate epigenetic landscape of the TME and provide valuable insights for cancer research and treatment strategies. Our services include, but are not limited to:

• Unveiling TME Dynamics through DNA Methylation Analysis
  We employ technologies, such as bisulfite sequencing or array-based methods, to map DNA methylation patterns and offer valuable insights into the dynamics of the TME. Through the utilization of high-resolution DNA methylation analysis, we can detect differentially methylated regions that are associated with TME characteristics.
• Decoding Immune Response in TME through Histone Modification Profiling
  We utilize chromatin immunoprecipitation followed by sequencing (ChIP-seq) to map genome-wide histone modifications in immune cells like T cells. By profiling histone marks, such as acetylation, methylation, and phosphorylation, we can gain insights into the functional states of genes involved in immune response and tumor-stroma interactions.
• Revealing Non-coding RNA Crosstalk in TME
  Using sequencing techniques like small RNA-seq and RNA-seq, we can assist in the identification of distinct microRNAs involved in the crosstalk between cancer cells and immune cells within the TME. Furthermore, we can profile the expression patterns of non-coding RNAs and identify those that are dysregulated in relation to tumor progression and immune response.
