Summary
Large-scale sequencing reveals cancer genome landscapes with common and rare mutated genes. This highlights significant tumor heterogeneity and suggests more driver mutations in cancer development than previously thought.
Area of Science:
- Genomics
- Cancer Biology
- Systems Biology
Background:
- Large-scale sequencing enables analysis of protein-coding regions in cancer genomes.
- Identifying mutated genes is crucial for understanding common human cancers.
Purpose of the Study:
- To analyze genomic landscapes of human tumors from various origins.
- To identify frequently and infrequently mutated genes in cancer.
- To understand the heterogeneity of mutated genes and potential driver mutations.
Main Methods:
- Unbiased mutation analyses of human tumors (breast, colon, brain, pancreas).
- Genomic landscape analysis to identify mutation patterns.
Main Results:
- Cancer genomes show a mix of frequently and infrequently mutated genes.
- Significant heterogeneity in mutated genes exists even within the same tumor type.
- Evidence suggests a higher number of driver mutations in tumorigenesis than previously assumed.
- Emerging central molecular pathways from the multitude of mutated genes.
Conclusions:
- Cancer development involves a complex interplay of numerous driver mutations.
- Systems biology approaches are essential for defining core cancer pathways.
- Predicting and experimentally determining mutant phenotypes will advance cancer understanding and drug discovery.

02:07Tumor Progression
Tumor progression is a phenomenon where the pre-formed tumor acquires successive mutations to become clinically more aggressive and malignant. In the 1950s, Foulds first described the stepwise progression of cancer cells through successive stages.
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

03:03mTOR Signaling and Cancer Progression
The mammalian target of rapamycin or mTOR protein was discovered in 1994 due to its direct interaction with rapamycin. The protein gets its name from a yeast homolog called TOR. The mTOR protein complex in mammalian cells plays a major role in balancing anabolic processes such as the synthesis of proteins, lipids, and nucleotides and catabolic processes, such as autophagy in response to environmental cues, such as availability of nutrients and growth factors.

01:19Interactions Between Signaling Pathways
Signaling cascades usually lack linearity. Multiple pathways interact and regulate one another, allowing cells to integrate and respond to diverse environmental stimuli.
Convergence and divergence, and cross-talk between signaling pathways
Two distinct signaling pathways can converge on a single functional unit, which may either be a single protein or a complex of proteins. The response is either functionally distinct or synergistic between the two pathways but different from the response...

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...
