Summary
Cancer cell transformation involves DNA methylation changes. This study challenges the idea that promoter hypermethylation in cancer occurs in a coordinated manner, using selective profiling over time.
Area of Science:
- Cancer Biology
- Epigenetics
- Genomics
Background:
- Aberrant DNA methylation, particularly promoter hypermethylation, is a hallmark of cancer cellular transformation.
- The prevailing view suggests that DNA methylation changes in cancer occur in an orchestrated, coordinated fashion.
Purpose of the Study:
- To investigate the temporal dynamics of DNA methylation during cellular transformation.
- To challenge the established notion of orchestrated hypermethylation in cancer development.
Main Methods:
- Utilized a novel selective high-resolution profiling technique.
- Monitored DNA methylation patterns over a time course of cellular transformation.
Main Results:
- Demonstrated that DNA methylation changes during cellular transformation do not follow a strictly orchestrated pattern.
- Provided high-resolution temporal data on DNA methylation dynamics.
Conclusions:
- The study challenges the long-held belief in an orchestrated model for cancer-associated promoter hypermethylation.
- Findings suggest a more complex and potentially stochastic process in the epigenetic landscape of cancer development.

Cancers 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...
Mouse Models of Cancer Study
Mice have long served as models for studying human biology and pathology because of their phylogenetic and physiological similarity with humans. They are also easy to maintain and breed in the laboratory, and hence, many inbred strains are now available for research. Studies on mice have contributed immeasurably to our understanding of cancer biology.
The development of transgenic, knockout, and knock-in mice has led to an exponential increase in their use as model organisms in research,...

Epigenetic Regulation
Epigenetic changes alter the physical structure of the DNA without changing the genetic sequence and often regulate whether genes are turned on or off. This regulation ensures that each cell produces only proteins necessary for its function. For example, proteins that promote bone growth are not produced in muscle cells. Epigenetic mechanisms play an essential role in healthy development. Conversely, precisely regulated epigenetic mechanisms are disrupted in diseases like cancer.

Adaptive Mechanisms in Cancer Cells
Cancer cells accumulate genetic changes at an abnormally rapid rate due to the defects in the DNA repair mechanisms. From an evolutionary perspective, such genetic instability is advantageous for cancer development. Mutant cell lines accumulate a series of beneficial mutations that contribute to their progression into cancer.
Some of the advantages that cancer cells have on normal cells include - enhanced ability to divide without terminally differentiating, induce new blood vessel formation,...

Cancer-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.

mTOR 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.
