It’s about epigenetics – a science that studies changes in genes.
Specialists study the role of epigenetics, that is, changes in genes, in development Cancer.
A new study by the Cancer Research Institute confirms this. Write The BBC quoted Professor Trevor Graham, Director of the Center for Evolution and Cancer at the Institute of Cancer Research, London.
Conclusions Published In Nature, the world’s most prestigious peer-reviewed scientific journal.
Epigenetics is the study of heritable changes in appearance or gene expression caused by mechanisms other than changes in the sequence of DNA nucleotides. So-called “dark matter” could change the way cancer is diagnosed and treated, scientists say.
Analyzing more than 1,300 samples from 30 types of colon cancer, scientists found that epigenetic changes are more common in cancer cells and cause them to grow more than other cells.
The experts also examined samples taken from different parts of the same tumor. It has been found that the development of cancer cells often depends on factors other than DNA mutations.
The researchers say their findings cannot prove that epigenetic changes directly lead to changes in cancer behavior, and more work needs to be done to show how this happens.
This discovery will lead to the creation of new forms of oncology testing that will help in tailoring treatment.
At the same time, it is still too early to talk about the results of the study. Specialists are on the first steps on the way to the truth.
For most people, they explain, genes are structural changes in the DNA code that are passed down from generation to generation.
As a result, much attention has been paid to how these gene mutations drive cancer development.
According to doctors, epigenetics is the study of how human behavior and environment cause changes that affect the function of its genes.
Human epigenetics change with age, where you live, and how you live.
Epigenetics does not change the DNA code, but it can control access to genes, thought to play an important role in cancer development.
“We’ve discovered another layer of how cancers behave. We call this ‘cancer dark matter,'” said Professor Trevor Graham.
In each cell, he says, “strands of DNA can curl up into balls” that affect which genes are read.
The location of the nodules is important in determining the nature of the cancer, he added.
“It won’t change clinical care tomorrow, but it will pave the way for the development of new treatments,” Graham said.
Genetic testing for cancer mutations, such as BRCA, that increase breast cancer risk, for example, only provides a fraction of the risk of developing cancer.
“By testing genetic and epigenetic changes, we can be more accurate in predicting which therapy is best for a particular person’s cancer,” Professor Graham explained.
Earlier, specialists from the Ministry of Health gave an update on the incident breast cancer In Ukraine.
