  2. Cancer genome sequencing - Wikipedia

    en.wikipedia.org/wiki/Cancer_genome_sequencing

    Cancer genome sequencing can be used to provide clinically relevant information in patients with rare or novel tumor types. Translating sequence information into a clinical treatment plan is highly complicated, requires experts of many different fields, and is not guaranteed to lead to an effective treatment plan. [21] [22]

  3. Carcinogenesis - Wikipedia

    en.wikipedia.org/wiki/Carcinogenesis

    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)).

  4. HeLa - Wikipedia

    en.wikipedia.org/wiki/HeLa

    HeLa cells are rapidly dividing cancer cells, and the number of chromosomes varies during cancer formation and cell culture. The current estimate (excluding very tiny fragments) is a "hypertriploid chromosome number (3n+)", which means 76 to 80 total chromosomes (rather than the normal diploid number of 46) with 22–25 clonally abnormal ...

  5. Oncogenomics - Wikipedia

    en.wikipedia.org/wiki/Oncogenomics

    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.

    Visit Gene Alterations and Cancer to learn more about epigenetic alterations. Chromosomal rearrangement: Every living creature has chromosomes, which are substantial strands of DNA that contain the genes for a cell. A chromosome's DNA sequence may alter each time a cell divides.

  7. DNA sequencing - Wikipedia

    en.wikipedia.org/wiki/DNA_sequencing

    This method of sequencing utilizes binding characteristics of a library of short single stranded DNA molecules (oligonucleotides), also called DNA probes, to reconstruct a target DNA sequence. Non-specific hybrids are removed by washing and the target DNA is eluted. [136] Hybrids are re-arranged such that the DNA sequence can be reconstructed.

    As with most blood tests, false-negatives can happen, meaning results could come back negative when a cancer does exist — although Grail reports that negative cancer test results from Galleri ...

  9. Molecular cytogenetics - Wikipedia

    en.wikipedia.org/wiki/Molecular_cytogenetics

    Today, the study of molecular cytogenetics can be useful in diagnosing and treating various malignancies such as hematological malignancies, brain tumors, and other precursors of cancer. The field is overall focused on studying the evolution of chromosomes, more specifically the number, structure, function, and origin of chromosome abnormalities.
