Cancer is the only disease that is a severe threat and a dark fear to mankind for many centuries. Cancer being a highly complex combination of diseases, it can be studied and understood better by the complex networks in Systems Biology & Network pharmacology approach. Here is a novel step to study the relation between drug target network and the corresponding drug network using the advanced concept of proteomics and systems biology and to develop an effective strategy for cancer prevention. We constructed gene co-expression networks and identified the globally cancer-related genes by network structure analysis. To study the properties of networks, modules were identified and their functions and roles were investigated. Our results showed that the inferred networks were structurally conservative and the identified modules were highly overlapped between various data sets. From this network the different interactions of the ligands and the proteins were observed. From the data obtained and the various analysis done the antimutagen Beta-Sitosterol obtained from the Black cumin Seeds (Nigella Sativa) shows least RMSD value with the protein 2I1J corresponding to the gene UTP14A.

Of this only 81 structure were available and taken from the Pubchem database. The PDB ids of the Breast cancer genes were taken. Docking was performed with the help of Quantum docking software and the docking scores were obtained. The list of gene ids obtained is loaded into the VISANT application. From the data obtained and the various analysis done the antimutagen Beta-Sitosterol obtained from the Black cumin Seeds (Nigella Sativa) shows least RMSD value with the protein 2I1J corresponding to the gene UTP14A indicating that Breast cancer specific drugs are specific for the particular disease gene and not random among the networks. The ligands (Antimutagens) show good response to the specific type of cancer.

Cancer is a class of diseases in which a group of cells display uncontrolled growth, invasion, and sometimes metastasis.. Prostate cancer is a form of cancer that develops in the prostate, a gland in the male reproductive system. Most prostate cancers are slow growing. However, there are cases of aggressive prostate cancers. The cancer cells may metastasize from the prostate to other parts of the body, particularly the bones and lymph nodes. Loss of PTEN and concomitant activation of AKT could act in partnership with the TMPRSS2-ERG fusion protein to promote progression to prostate cancer through downstream pathways that increase the selective advantage of pre malignant prostatic intraepithelial neoplasia cells.

: The past two decades have seen an explosive increase in the number of people diagnosed with diabetes mellitus worldwide, particularly type 2 diabetes (T2D), which is found associated with modern lifestyle, abundant nutrient supply, reduced physical activity, and obesity. Actually, between 60 and 90% of cases of T2D now appear to be related to obesity. Numerous studies have shown that insulin resistance precedes the development of hyperglycemia in subjects that eventually develop T2D. There are lots of chemical agents available to control and to treat diabetic patients, but total recovery from diabetes has not been reported up to this date. Alternative to these synthetic agents, plants provide a potential source of hypoglycemic drugs and are widely used in several traditional systems of medicine to prevent diabetes. Several natural compounds have been investigated for their beneficial use in different types of diabetes.
