Introduction

Cancer is a group of diseases in which the body produces an excess of cells malignant, with growth and division beyond the normal limits (invasion of the tissue surrounding and sometimes metastasis). Metastasis is the spread at a distance, primarily via lymphatic or blood, cells originating from cancer, and the growth of new tumors in the destinations of such metastases. These properties differentiate benign from malignant tumors, which limited and do not invade or metastasize. Normal cells at the contact with neighboring cells inhibit reproduction, but the malignant cells do not have this break. Most cancers form tumors, but some do not (such as leukemia) (Butte, Pena-Cruz, et al, 2008, p. 3567-3572). Cancer can affect all ages, even fetuses, but the risk increases the more common with age. Cancer causes about 13% of all deaths. According to the American Cancer Society, 7.6 million people died of cancer in the world during 2007.

This paper would focus on the analysis of different studies that have presented different methods for the treatment of cancer. Furthermore, the study would also present a critical analysis and significance of the studies that are to be analyzed in this paper.

Background of the Study

Interactions of protein-protein association relates to the protein molecules and the study of these associations from the perspective of biochemistry, signal transduction and networks. Interaction between proteins are important for many biological functions. For example, signals from outside of a cell are mediated to the inside of that cell by interactions of the protein-protein signaling molecules (Butte, Pena-Cruz, et al, 2008, p. 3567-3572). This process, called signal transduction, plays a key role in many biological processes and many diseases (eg cancer). Protein could interact long to form part of a protein complex, a protein can be another protein (for example, from cytoplasm to nucleus or vice versa in the case of nuclear pore of importins), or a protein may act interact only briefly with another protein to modify (for example, protein kinase add a phosphate to a target protein). This modification of proteins can be the interactions of protein-protein change. For example, some proteins with SH2 domains bind to other proteins only when phosphorylated at amino acid tyrosine. The interactions of protein-protein are of central importance for virtually every process in a living cell (Butte, Pena-Cruz, et al, 2008, p. 3567-3572). Information about these interactions improves our understanding of disease and may provide the basis for new therapeutic approaches.

Discussion

Cancer: the protein responsible for the discovery! Breakthrough for the treatment of cancer!

According to many is the most important discovery in the history of oncology, one that could make the breakthrough in the treatment of this terrible disease would be a trivial protein, the source of growth of tumors and generation of metastases. By blocking this degenerative process, and, therefore, the feared spread of metastases, Canadian scientists say so to stop the degenerative mechanism that leads to the death of the patient, making it possible to isolate the tumor and immune to concentrate the battle ...
