A tumor suppressor gene (TSG), or anti-oncogene, is a gene that regulates a cell during cell division and replication. [1] If the cell grows uncontrollably, it will result in cancer . When a tumor suppressor gene is mutated, it results in a loss or reduction in its function.

[4] [5] A tumor suppressor would trigger an apoptotic pathway in a cancer cell if there were DNA damage, polyploidy, or uncontrolled cell growth. Simultaneously, tumor cells need to upregulate oncogenes , which promote or cause downstream activation of growth factors and cell survival signals such as RAS, [ 6 ] Mitogen-activated protein kinase ...
Many of the genes involved in the Hippo signaling pathway are recognized as tumor suppressors, while Yki/YAP/TAZ is identified as an oncogene. YAP/TAZ can reprogram cancer cells into cancer stem cells. [26] YAP has been found to be elevated in some human cancers, including breast cancer, colorectal cancer, and liver cancer.
For a normal cell to transform into a cancer cell, the genes that regulate cell growth and differentiation must be altered. [95] The affected genes are divided into two broad categories. Oncogenes are genes that promote cell growth and reproduction. Tumor suppressor genes are genes that inhibit cell division and survival. Malignant ...
SDPR functions as a metastasis suppressor in breast cancer, potentially by priming cells to apoptosis. [8] Cancer cells suppress the gene via promoter DNA methylation hence exemplifies the significance of epigenetic changes in cancer progression. [9] [10] KISS1 is found in melanoma and breast cancers. It acts by synthesizing a protein receptor.
Research shows gene defect's role in autism-like behavior; Dance Your PhD 2017 : A Story of Tumor Suppression Deepti Mathur. PTEN and cancer explained in dance. A metabolic pathway uses glutamine to create a component of DNA. This pathway is regulated in part by PTEN. Loss of PTEN allows the pathway to go into overdrive, leading to cancer.
Under this model, cancer arises as the result of a single, isolated event, rather than the slow accumulation of multiple mutations. [4] The exact function of some tumor suppressor genes is not currently known (e.g. MEN1, WT1), [5] but based on these genes following the Knudson "two-hit" hypothesis, they are strongly presumed to be suppressor genes.
