Summary
Synonymous mutations, though silent, can impact protein function and cancer development. This study found a recurrent synonymous mutation in BCL2L12 that enhances its oncogenic properties in melanoma.
Area of Science:
- Genomics
- Molecular Biology
- Cancer Research
Background:
- Synonymous mutations, previously overlooked, can alter protein function.
- Their role in cancer genomics remains largely unexplored.
Purpose of the Study:
- To investigate the functional impact of synonymous mutations in cancer.
- To identify and characterize recurrent synonymous mutations in melanoma.
Main Methods:
- Whole-genome and whole-exome sequencing of melanoma samples.
- Validation of identified mutations in a larger cohort.
- Analysis of microRNA targeting and protein function.
Main Results:
- A recurrent synonymous mutation (F17F) in BCL2L12 was identified in melanoma.
- This mutation increases BCL2L12 mRNA and protein levels via altered microRNA targeting.
- Mutant BCL2L12 enhances apoptosis inhibition and suppresses p53-mediated transcription.
Conclusions:
- Recurrent somatic synonymous mutations are selected in cancer.
- Silent genetic alterations play a significant role in human cancer.
- Further investigation of synonymous mutations is crucial for cancer genome studies.

02:21Cancers Originate from Somatic Mutations in a Single Cell
Cancer arises from mutations in the critical genes that allow healthy cells to escape cell cycle regulation and acquire the ability to proliferate indefinitely. Though originating from a single mutation event in one of the originator cells, cancer progresses when the mutant cell lines continue to gain more and more mutations, and finally, become malignant. For example, chronic myelogenous leukemia (CML) develops initially as a non-lethal increase in white blood cells, which progressively...

01:05Cancer-Critical Genes II: Tumor Suppressor Genes
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.

01:12Loss of Tumor Suppressor Gene Functions
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...
