    en.wikipedia.org/wiki/Glioblastoma

    Glioblastoma, previously known as glioblastoma multiforme (GBM), is the most aggressive and most common type of cancer that originates in the brain, and has a very poor prognosis for survival. [6][7][8] Initial signs and symptoms of glioblastoma are nonspecific. [1] They may include headaches, personality changes, nausea, and symptoms similar ...

    en.wikipedia.org/wiki/Human_genome

    Chromosomal changes during the cell cycle are displayed at top center. The mitochondrial genome is shown to scale at bottom left. The human genome is a complete set of nucleic acid sequences for humans, encoded as the DNA within each of the 24 distinct chromosomes in the cell nucleus. A small DNA molecule is found within individual mitochondria.

  4. Genetic testing - Wikipedia

    en.wikipedia.org/wiki/Genetic_testing

    Genetic testing is "the analysis of chromosomes (DNA), proteins, and certain metabolites in order to detect heritable disease-related genotypes, mutations, phenotypes, or karyotypes for clinical purposes." [11] It can provide information about a person 's genes and chromosomes throughout life.

  5. Cancer screening - Wikipedia

    en.wikipedia.org/wiki/Cancer_screening

    The objective of cancer screening is to detect cancer before symptoms appear, involving various methods such as blood tests, urine tests, DNA tests, and medical imaging. [1][2] The purpose of screening is early cancer detection, to make the cancer easier to treat and extending life expectancy. [3] In 2019, cancer was the second leading cause of ...

  6. Oncogenomics - Wikipedia

    en.wikipedia.org/wiki/Oncogenomics

    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.

  7. Human Y-chromosome DNA haplogroup - Wikipedia

    en.wikipedia.org/wiki/Human_Y-chromosome_DNA_ha...

    Genetic genealogy. In human genetics, a human Y-chromosome DNA haplogroup is a haplogroup defined by specific mutations in the non- recombining portions of DNA on the male-specific Y chromosome (Y-DNA). Individuals within a haplogroup share similar numbers of short tandem repeats (STRs) and single-nucleotide polymorphisms (SNPs). [2]

  8. Relationship between telomeres and longevity - Wikipedia

    en.wikipedia.org/wiki/Relationship_between...

    Telomeres at the end of a chromosome. The relationship between telomeres and longevity and changing the length of telomeres is one of the new fields of research on increasing human lifespan and even human immortality. [1][2] Telomeres are sequences at the ends of chromosomes that shorten with each cell division and determine the lifespan of ...

    Checked. Lacks c. 1945–1951. [A] Henrietta Lacks (born Loretta Pleasant; August 1, 1920 – October 4, 1951) [2] was an African-American woman [5] whose cancer cells are the source of the HeLa cell line, the first immortalized human cell line [B] and one of the most important cell lines in medical research. An immortalized cell line ...
