What causes cancer cell proliferation?
Cancer is unchecked cell growth. Mutations in genes can cause cancer by accelerating cell division rates or inhibiting normal controls on the system, such as cell cycle arrest or programmed cell death. As a mass of cancerous cells grows, it can develop into a tumor.
What is carcinoma cell line?
(KAN-ser sel line) Cancer cells that keep dividing and growing over time, under certain conditions in a laboratory. Cancer cell lines are used in research to study the biology of cancer and to test cancer treatments.
What is the structure of a cancer cell?
Cancer cells grow and divide at an abnormally rapid rate, are poorly differentiated, and have abnormal membranes, cytoskeletal proteins, and morphology. The abnormality in cells can be progressive with a slow transition from normal cells to benign tumors to malignant tumors.
Do cancer cells undergo apoptosis?
Cancer cells can ignore the signals that tell them to self destruct. So they don’t undergo apoptosis when they should.
What are the 8 characteristics of cancer cells?
These hallmarks constitute an organizing principle for rationalizing the complexities of neoplastic disease. They include sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, and activating invasion and metastasis.
How is cancer cell produced?
Cancer is a disease caused when cells divide uncontrollably and spread into surrounding tissues. Cancer is caused by changes to DNA. Most cancer-causing DNA changes occur in sections of DNA called genes. These changes are also called genetic changes.
Where do cancer stem cells come from?
Cancer stem cells (CSCs) are a subpopulation of tumor cells that can drive tumor initiation and can cause relapses. At the time point of tumor initiation, CSCs originate from either differentiated cells or adult tissue resident stem cells.
What is the cancer cell line Encyclopedia?
Motivations for the Cancer Cell Line Encyclopedia (CCLE) Cancer cell lines are the most commonly used models for studying cancer biology, validating cancer targets and for defining drug efficacy. Prior to the CCLE, cell line investigations were limited to a few commonly used cell lines or at most the 60 cell lines of the NCI60 panel.
What is the 3cell lines project V90?
Cell Lines Project v90, released 05-SEP-19. COSMIC, the Catalogue Of Somatic Mutations In Cancer, is the world’s largest and most comprehensive resource for exploring the impact of somatic mutations in human cancer.
Can larger-scale genetic characterization of cancer cell lines reveal drug sensitivity?
In aggregate, these data suggested that larger-scale genetic characterization of the cancer cell lines coupled to compound or other cell perturbations might unveil predictive drug sensitivities in cancer. Nature 2005;436 (7047):117‐122. DOI:10.1038/nature03664 Nature 2006;439 (7074):358‐362. DOI:10.1038/nature04304
How many cell lines were used prior to the CCLE?
Prior to the CCLE, cell line investigations were limited to a few commonly used cell lines or at most the 60 cell lines of the NCI60 panel. For example, at the time of the discovery of EGFR mutations in lung cancer, EGFR inhibitors had been developed using a single cell line, A549 as the EGFR-inhibitor sensitive model.
