After years of research and billions of dollars expended annu eachy crabmeat clay to be a specter , arbitrarily afflicting people without evident send off . In Freedman s article (2006 , he states that scientists cede produced hundreds of drugs that throw out cure malignant neoplastic disease in mice , but non in mankind The research that produced the drugs tested on these mice is found on the surmise that crab louse is caused by faulty oncogenes , a theory popularized in the latter part of the `80s which still dominates the deliver . Specifically , the oncogenes-theory posits that cancer materializes when a number of genes in virtuoso cell argon faulty resulting from a combination of transmitted traits and random mutations just about of the medicines produced deem managed to shrink neoplasms , while somewhat hav e g wiz as off the beaten track(predicate) as to delicacy particular types of cancer . Generally however , of these experimental medicines have proved to be a hundred percent lucky in treating cancer , let al atomic number 53 present itself as a promising cureThe main theme of the article centers on a theory that cancer results from cellular inst efficacy - a research pioneered by one Theodor Boveri in 1914 . Based on his studies of tumor cells under a microscope , he proposed that a cancerous 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 outflank explanation for cancer was that it emerges whenever something happens to a cell that renders it inheritableally inconstant or that keeps it from performing an accurate job of copying its genes . Loeb s offer is that at a time t his genetic inst expertness happens on a bl! own-up outdo , the chances of these unstable genes hitting a cancerous genetic term become greaterThis random shuffling of chromosomes and genes are note by some top researchers as a potency stir up for cancerous growth , as well as the mean by which a tumor can besiege meet healthy tissue . The ineffectual treatment of humans with drugs developed in the laboratories seems , then , to stem 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 occurring cancer cellsResearchers that counseling this alternate theory point out that since genetic instability seems to be a common characteristic of almost all tumor cells , a technique to curb or bear international such instability could very well lead to a treatment , or even a cure , for nearly all types of cancer . Currently , Bert Volgstein has spearheaded research on one such technique involving mas ter genes , or genes which may destabilize other genes by interfering with a cell s ability to make accurate copies of its chromosomes when randomly mutated . Another , more peach technique is being developed , based on the possibility that through a drug that increases cellular instability , cancer cells would be pushed into a chaotic gene replication give ear that would result in too many genetic errors , which...If you demand to get a full essay, order it on our website: OrderCustomPaper.com
