  • Normal cells only grow when they receive such signals. (cancer.gov)
  • Cancer is a genetic disease-that is, it is caused by changes to genes that control the way our cells function, especially how they grow and divide. (cancer.gov)
  • Radiation damages the DNA inside cells, making them unable to divide and grow. (mayfieldclinic.com)
  • But sometimes cells keep dividing and grow out of control. (nhsinform.scot)
  • Because of its mutated aggressive genetics, this cell has a selective growth advantage over its neighbors. (medscape.com)
  • [ 6 ] These events lead the cancer cell to escape normal cell growth and control mechanisms, to avoid system control mechanisms (ie, immunologic surveillance), and to establish a nutrient supply. (medscape.com)
  • If cell growth is uncontrolled, it can lead to childhood cancer in people with CMMRD syndrome. (medlineplus.gov)
  • Kinesin-II is not essential for mitosis and cell growth in Chlamydomonas. (bio.net)
  • In normal cells, tumor suppressor genes prevent cancer by slowing or stopping cell growth. (cancer.gov)
  • In our studies, we have found the mechanism that control KLHL6 function, allowing us to regulate if not block the abnormal growth of B-cells. (lls.org)
  • When this process does not occur properly, unregulated cell growth may be the end result. (cancerquest.org)
  • This first category also includes genes that contribute to tumor growth by inhibiting cell death. (cancerquest.org)
  • As shown below, binding of the growth factor can lead to cell division. (cancerquest.org)
  • None of these indicators of regular function can be detected in immune cells from mice lacking ATM. (nih.gov)
  • T-cells that can fight infection directly and recruit other immune cells. (lymphoma.org.au)
  • During this stage of germ cell development, aberrant chromatid exchange events associated with crossing over can occur. (medscape.com)
  • During the cell cycle, a cell grows and divides to produce two new cells, and then the process starts all over again. (nih.gov)
  • Telomeres provide a buffer that grows shorter every time a cell divides. (cdc.gov)
  • Sometimes referred to as oat cell cancer, SCLC is characterized by small, oval-shaped cells that resemble oat grains when viewed under a microscope. (moffitt.org)
  • of errors that occur as cells divide. (cancer.gov)
  • A genetically mediated series of events by means of which cells actively trigger their own destruction. (ucsfhealth.org)
  • When they become cancerous lymphoma cells, you cannot fight infection as easily. (lymphoma.org.au)
  • Their normal function is not to cause cancer but to participate in the regulation of normal cell division. (the-scientist.com)
  • The abnormal cells showed more variations in their cell-division cycles than normal cells, the researchers found. (livescience.com)
  • While normal cells all developed at similar paces, abnormal cells lagged behind or sped ahead in the divisions of the first, second and third cells. (livescience.com)
  • However, the normal squamous cells can be replaced by cells that resemble, in part, what is found in the small intestine. (nyp.org)
  • RhoC seems to cause very specific and robust changes in the inflammatory breast cancer model that differ from not only normal-like cells, but also other types of breast cancer," says study co-first author Joel A. Yates, Ph.D., a senior postdoctoral research fellow at U-M. (phys.org)
  • rely on different kinds of nutrients than normal cells. (cancer.gov)
  • Normal cells divide (reproduce) in a controlled way. (sarahbush.org)
  • The genes that have been identified to date have been categorized into two broad categories, depending on their normal functions in the cell. (cancerquest.org)
  • Despite the differences in their normal roles, these genes all contribute to unregulated cell division if they are present in a mutant (oncogenic) form. (cancerquest.org)
  • Although activating telomerase to immortalize normal cells is a theoretical possibility, its feasibility isn't known. (cdc.gov)
  • Hodgkin Lymphoma is identified when the cancerous B-cells develop in a certain way and become Reed-Sternberg cells - which look very different from normal B-cells. (lymphoma.org.au)
  • To explain the origin of occult carcinoma in situ cells, 2 models have been proposed. (medscape.com)
  • They took 75 human embryos that had been frozen at the single-cell phase and cultured them in Petri dishes for two days, taking a microscopic snapshot of each embryo every five minutes. (livescience.com)
  • Cells on their own are microscopic - meaning they are so small we can not see them. (lymphoma.org.au)
  • This is in contrast with tumor suppressor genes which must BOTH be defective to lead to abnormal cell division. (cancerquest.org)
