A significant advancement in the field of cancer epigenetics, this study has mapped the pathways of 1.7 million cells in various cancers. It has revealed distinct patterns of DNA activation that play a crucial role in cancer development. This offers promising avenues for better understanding of prognosis and designing specific treatment approaches.
Cells produce proteins by interpreting genetic codes in genes. When mutations occur in these codes, they can disrupt protein functions. This aspect is known as cancer genetics. Recently, however, a new aspect has emerged: cancer epigenetics.
Cancer and Epigenetic Modifications
Epigenetic changes, unlike mutations, don’t alter genetic information but temporarily affect a cell’s capacity to access certain genes, impacting protein production. These epigenetic mechanisms regulate overall cellular function and, when disrupted, can initiate the process of malignant transformation.
The study was partially led by Dr. Eduard Porta of the Josep Carreras Leukaemia Research Institute.
Understanding Cancer’s Epigenetic Shift
An international research team has made strides in understanding this aspect of cancer. They analyzed 1.7 million cells from 225 samples, derived from 205 patients with 11 different types of cancer, both primary and metastatic.
The team analyzed each cell’s transcriptome, exome, and epigenome, covering gene mutations, accessibility, and impacts. Using extensive computational analysis, they linked each cell’s functional status to its specific cancer type.
Published in Nature, the study revealed distinct patterns of DNA activation or deactivation unique to each cancer type, effectively creating a signature for each tumor. These patterns are key to understanding cancer progression.
Dr. Eduard Porta, a leading researcher at the Josep Carreras Leukaemia Research Institute, contributed significantly to this study with his expertise in biological data analysis.
Epigenetic Changes as Central to Cancer
The study highlights epigenetic changes as fundamental in cancer development. In particular, the accessibility of enhancer regions, crucial in regulating multiple genes, has been emphasized.
The results pinpoint a set of genes useful as markers for predicting prognosis, aiding patient management. Moreover, the study identified the pathways of these key genes, revealing their extended interactions. While directly targeting some of these genes may cause side effects, understanding their pathways allows for the development of treatments targeting more vulnerable points, maximizing therapeutic efficacy and reducing adverse effects.
