Oncogenomics is a sub-field of genomics that characterizes cancer-associated genes.It focuses on genomic, epigenomic and transcript alterations in cancer. Cancer is a genetic disease caused by accumulation of DNA mutations and epigenetic alterations leading to unrestrained cell proliferation and neoplasm formation.
The Cancer Genome Atlas (TCGA) is a project to catalogue the genomic alterations responsible for cancer using genome sequencing and bioinformatics. [1] [2] The overarching goal was to apply high-throughput genome analysis techniques to improve the ability to diagnose, treat, and prevent cancer through a better understanding of the genetic basis of the disease.
The unique mutations for each cancer allowed for the 21 samples to be categorized based on type and subtype of cancer, showing a relationship between mutations and the type of resulting cancer. While the group was able to identify these mutations they were unable to determine the underlying mechanisms resulting in them. [10]
The central role of DNA damage and epigenetic defects in DNA repair genes in carcinogenesis. DNA damage is considered to be the primary cause of cancer. [17] More than 60,000 new naturally-occurring instances of DNA damage arise, on average, per human cell, per day, due to endogenous cellular processes (see article DNA damage (naturally occurring)).
A series of mutations is required in the process of carcinogenesis for a cell to transition from being normal to pre-malignant and then to a cancer cell. [86] The mutated genes usually belong to classes of caretaker, gatekeeper, landscaper or several other genes. Mutation ultimately leads to acquisition of the ten hallmarks of cancer.
Most cases of lung cancer are because of genetic mutations in EGFR, KRAS, STK11 (also known as LKB1), TP53 (also known as p53), and CDKN2A (also known as p16 or INK4a) [117] [118] [119] with the most common type of lung cancer being an inactivation at p16. p16 is a tumor suppressor protein that occurs in mostly in humans the functional ...
The 16 possible mutation types of the substitution class C>A are shown as an example. Once the mutation catalog (e.g. counts for each of the 96 mutation types) of a tumor is obtained, there are two approaches to decipher the contributions of different mutational signatures to tumor genomic landscape:
BRCA gene mutations: The tumor suppressing BRCA genes frequently help in cancer prevention. They control how cells divide and develop and help repair DNA damage BRCA gene abnormalities, however, can the likelihood of having specific cancers is raised. Cancers BRCA1 and BRCA2 are the two BRCA recognized cancer-causing gene alterations.
