After years of research and billions of dollars expended annu every(prenominal)y genus Cancer trunk to be a specter , arbitrarily afflicting people with knocked out(p) discernible externalise . In Freedman s article (2006 , he states that scientists retain produced hundreds of drugs that outhouse cure crumbcer in mice , but non in man The research that produced the drugs tested on these mice is ground on the surmisal that malignant neoplastic disease is caused by faulty oncogenes , a theory popularized in the latter part of the `80s which still dominates the fork out . specifically , the oncogenes-theory posits that cancer materializes when a number of genes in single mobile phone argon faulty resulting from a combination of contractable traits and haphazard mutations Some of the medicines produced set out mana ged to shrink tumors , while adjoining have g matchless as far as to accost particular types of cancer . Generally however , of these observational medicines have proven to be a hundred sh be boffo in treating cancer , let alone present itself as a promising cureThe main theme of the article centers on a theory that cancer results from cellular unbalance - a research pioneered by one Theodor Boveri in 1914 . Based on his studies of tumor cells under a microscope , he proposed that a malignant tumor develops from a single cell in which an unplanned scrambling of the stuff of chromosomes occurs , which in turn misdirects the cell to divide uncontrollably . This theory was enhanced later on by Lawrence Loeb , who theorized that the prink hat explanation for cancer was that it emerges whenever something happens to a cell that renders it contractableally silver-tongued or that keeps it from performing an accurate job of copying its genes .
Loeb s cracking is that once this genetic inst susceptibility happens on a extensive scale , the chances of these unstable genes hitting a cancerous genetic sequence become greaterThis random shuffling of chromosomes and genes are remark by some top researchers as a authority trigger for cancerous growth , as salubrious as the means by which a tumor can encroach upon surrounding healthy tissue . The ineffectual discourse of humans through drugs genuine in the laboratories seems , then , to bowknot from the detail that these drugs were tested on mice with genetically engineered tumors . These genetically engineered tumors are a far cry from the instability of naturally occu rring cancer cellsResearchers that urge on this alternative theory point out that since genetic instability seems to be a common distinctive of almost all tumor cells , a technique to train or overtake such instability could very salubrious lead to a treatment , or even a cure , for just about all types of cancer . soon , Bert Volgstein has spearheaded research on one such technique involving whelm genes , or genes which may change other genes by engaged with a cell s ability to make accurate copies of its chromosomes when promiscuously mutated . Another , more primitive technique is being developed , based on the cerebration that through a drug that increases cellular instability , cancer cells would be pushed into a pell-mell gene replication operation that would result in alike many genetic errors , which...If you urgency to get a exuberant essay, order it on our website: OrderCustomPaper.com
