Biology of Cancer

Cancer, some effects of the mutant cells, both local and remote point control as needed to replicate the result of growing group of malignant diseases.. Normally the cells under a certain control, according to the segmentation are needed..Programmed cell death, on the one hand, or “apoptosis” is not the case when the experiment, the effects of growth factors from the other side of the replication..Mutations in this gene (change) suffered the cells they lead to excessive growth, then cancer, and these genes to create “onkogen” is called..

DNA can be regarded as a matter of life center..DNA is found in the genes. Genes, mother or father to child characteristics, such as black or blond hair or blue eyes or thalassemia (Mediterranean anemia), such as the inheritance of diseases are caused to pass..

DNA is like a long tape strip..States that our body how to grow, even the biological behavior of a program to determine the directory..DNA can be likened to computer programs, carrier tapes.

DNA, the cell core of the deoksiribonükleik acid acid is an acronym of the initials.Chromosomal DNA into cells are available..

In the human body has billions of cells and DNA in each cell is the cell’s control center..There are 23 chromosomes in the human couple..They are found in pairs in the kernel..Sex chromosomes is different as only the last women is found in the XX and XY in males.

Cancer genes, or towards the end of the onkogenler 70′li started and until today are very active subject of research by creating a better understanding of cancer, diagnosis and treatment services have to improve..

Onkogenleri creator of mutation, karsinojen substances, with the impact of viruses and X-ray occurs..After you have created a cancer in organ, tissue and organs in distant metastases as well, and we do not place patients are lost due to metastases..Fast progressive early metastasis of cancer, with a better outcome in cancer metastasis occurs late..Metastasis formation than coincidence, some organs of cancer cells depends on the features to ensure easy placement..For example, in liver and colon cancer, prostate cancer metastases to bone and prefers to do..Here, in cancer tissue blood flow, factors such as vascular cell activation plays a role..

It is also very important anti-onkogenler next Onkogenlerin..Onkogenler causes cancer, while the gene for anti-onkogenler cancer prevention..These are in natural state, while in that case is not subject to mutation and replication to be segmentation braking, the stop of the gene..As an example we can show the Retinoblastoma gene and p53 gene.
