Firstly, there is an unmistakable link between telomeres, telomerase, and cancer. In eukaryotic cells, the chromosomes are linear and undeviating DNA molecules1. Due to this fact and due to the natural technicalities of DNA replication, diminutive amounts of DNA are not replicated and are lost every time a cell divides1. To prevent irreplaceable and important genes from being lost and inflicting damage upon the cell, telomeres, which are non-coding strands of DNA, are present at the ends of the chromosomes2, 8. The shortening of telomeres is associated with the mortality of cells; when telomeres run out, the coding regions of the chromosomes are susceptible to be damaged instead, leading to the loss of cellular functions and eventual cell death2, 8. Telomeres are produced by an enzyme called telomerase, which ceases to be completely active after the development of the embryo2. Recent research has proven that telomere shortening paves the way for cancer, driving the gene...

- Inside the nucleus of our cells, our genes are on double-stranded molecules of DNA called chromosomes. At the top and bottom of the chromosomes are fragments of DNA known as Telomeres which defend our genes, give us the ability for our cells to divide, and hold secrets to how we age and how we get cancer. Telomeres are like the ends of shoelaces (because they keep the chromosomes’ ends from fraying). But when a cell divides, the Telomere gets smaller and shorter. When they get too short, the cell can’t divide.... [tags: DNA. chromosomes, telomeres]

- Structures and Roles of Telomeres Telomeres are essential structures in eukaryotic cells. Through repeat nucleotide sequencing of TTAGGG and their six associated protein complexes, they provide a “cap” over the rest of the chromosome, which protects the genetic material contained within the chromosome from instability1. Without the telomere structures, chromosomes are prone to tearing due to the action of nucleases and other damaging components within the nucleus. Torn chromosomes prove to be unstable, often fusing end-to-end or rearranging.... [tags: catallyst, cells, chromosome, telomerase, DNA]

- The naked mole-rate (NMR) is a mammal that can live up to three decades while the common household mouse lives up to 4 years. While NMR have died of natural age related causes, death because of cancer hasn't been observed (Liang, et al., 2010). Human telomerase reverse transcriptase (hTERT) role in tumorigenesis is important in the understanding of how cancer develops and grows. Figuring out how and why the NMR is cancer resistance could model how future anti- cancer drugs be more direct and effective in recognizing and destroy cancerous tumors....

- ... Telomerase is an enzyme which restores and maintains telomere length. Telomerase is comprised of an RNA component (TERC), which acts as a template strand to the telomeric DNA. This enables the telomeric DNA to be copied. The reverse transcriptase element (TERT) in telomerase acts to synthesise the new telomeric DNA strand. The mechanisms explaining how telomerase works are described in greater detail in the section: Telomerase in Cancer. Somatic cells, which are all cells in the body other than reproductive cells, show no or very little telomerase activity (Hiyama & Hiyama, 2007).... [tags: DNA, DNA replication, Telomerase, Telomere]

- Telomerase is the enzyme that maintains and prevents shortening of the protective telomeres at the ends of chromosomes. Without it, cells eventually enter replicative senescence (cell cycle arrest) as a result of telomere shortening from a lifetime of cell divisions. Due to the high expression of telomerase in invasive cancers, it makes for an attractive target for cancer therapy. In the quest for safer and more effective cancer therapies, researchers have explored many methods of targeting telomerase in cancer cells as a way to induce senescence or apoptosis (cellular death) including direct inhibition of telomerase, telomere disruption, telomerase-specific immunotherapy, and telomerase-sp...

- Telomere defence mechanisms have been recommended as potential targets for new anti-cancer interventions (Folini and Zaffaroni, 2005), as unlimited proliferative possibility has been identified as one of the six hallmarks of cancer. The selective reactivation of telomerase largely in human tumours, the ability to obstruct its expression or function is being actively explored. This includes the use of various approaches aimed, firstly to prevent the enzyme's catalytic activity; secondly to obstruct the expression of its components (i.e.... [tags: Cancer Research]

- So picture yourself, your mother or father has just undergone cancer treatment and now you are afraid that the disease could be passed down to you. Now picture yourself in the alternative knowing that the disease can be based down to you and your offspring and there are effective treatments in place. These are the studies that are being done in evolutionary biology of cancer and scientists are making great progress. Ecology and Evolutionary Biologists claim that natural selection has a factor in the genetics of cancer.... [tags: Evolution, Charles Darwin, Biology]

- Each of our bodies are made up trillions of cells, which each contain two meters worth of DNA wound into chromosomes. These structures define who we are and what we look like. They are essential for our health and all of our body functions. An important piece of our chromosomes,that are often forgotten, are telomeres. Telomeres are caps on the end of the chromosomes that keeps the strand together. They are like aglets, the plastic at the end of a shoe lace that keeps the shoe lace tied together and keeps it from fraying.... [tags: Cancer, DNA, Senescence, DNA replication]

- ... As mentioned before, nervous cells, with some exceptions, are not subject to cell turnover but depend on other cells which are subjected to cell turnover. For the photoreceptor cells (cones and rods), these cells are retina pigmented cells (RPC). Each day, every RPC, by phagocytosis, removes from roughly 50 photoreceptor cells, approximately 10% of the membranes having photopsin or rodhopsin molecules on them. These cells, which have a very high metabolic activity, show cell turnover and, when this turnover slows down, damaging substances such as A2E (a vitamin A-derived breakdown product) accumulates, cells of RPC layer rarefy and leave holes in the RPC layer....

- Biology is the science of living systems. It is inherently interdisciplinary, requiring knowledge of the physical sciences and mathematics, although specialities may be oriented toward a group of organisms or a level of organization. BOTANY is concerned with plant life, ZOOLOGY with animal life, algology with ALGAE, MYCOLOGY with fungi, MICROBIOLOGY with microorganisms such as protozoa and bacteria, CYTOLOGY with CELLS, and so on. All biological specialties, however, are concerned with life and its characteristics.... [tags: Biology]
