Germline Genetic Variation Modulates Tumor Immune Microenvironment
Cancer Discovery
|February 20, 2021
Summary
Patient genetics significantly influence how the body fights cancer. Understanding these genetic factors can improve antitumor immune responses at both molecular and cellular levels.
Area of Science:
- Immunology
- Genetics
- Oncology
Background:
- Antitumor immune responses are crucial for cancer treatment efficacy.
- Individual patient variability impacts treatment outcomes.
- The role of host genetics in shaping immune responses to cancer is increasingly recognized.
Purpose of the Study:
- To investigate the contribution of patient genetic background to antitumor immune responses.
- To elucidate the molecular and cellular mechanisms underlying these genetic influences.
Main Methods:
- Analysis of patient genetic data.
- Assessment of immune cell populations and functions.
- Molecular profiling of tumor microenvironment.
Main Results:

02:17The Tumor Microenvironment
7.2K
Every normal cell or tissue is embedded in a complex local environment called stroma, consisting of different cell types, a basal membrane, and blood vessels. As normal cells mutate and develop into cancer cells, their local environment also changes to allow cancer progression. The tumor microenvironment (TME) consists of a complex cellular matrix of stromal cells and the developing tumor. The cross-talk between cancer cells and surrounding stromal cells is critical to disrupt normal tissue...

01:27Tumor Immunotherapy
856
Immunotherapy is a treatment that boosts or manipulates the immune system to fight diseases, including cancer. For instance, by stimulating an immune response through vaccinations against viruses that cause cancers, like hepatitis B virus and human papillomavirus, these diseases can be prevented. Nonetheless, some cancer cells can avoid the immune system due to their rapid mutation and division. The immune response to many cancers involves three phases: elimination, equilibrium, and escape.

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
8.6K
Genes usually encode proteins necessary for the proper functioning of a healthy cell. Mutations can often cause changes to the gene expression pattern, thereby altering the phenotype.
When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
Such genes that act...

01:12Loss of Tumor Suppressor Gene Functions
5.4K
Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
When the tumor suppressor genes develop mutations or are lost, cells start growing out of control, leading to cancer. However, a single functional copy of the tumor suppressor gene is enough for the cells to maintain their normal functions and cell...

01:20Mismatch Repair
5.8K
Organisms are capable of detecting and fixing nucleotide mismatches that occur during DNA replication. This sophisticated process requires identifying the new strand and replacing the erroneous bases with correct nucleotides. Mismatch repair is coordinated by many proteins in both prokaryotes and eukaryotes.

02:23Abnormal Proliferation
4.9K
Under normal conditions, most adult cells remain in a non-proliferative state unless stimulated by internal or external factors to replace lost cells. Abnormal cell proliferation is a condition in which the cell's growth exceeds and is uncoordinated with normal cells. In such situations, cell division persists in the same excessive manner even after cessation of the stimuli, leading to persistent tumors. The tumor arises from the damaged cells that replicate to pass the damage to the...
