    cancerization, which is the same consecutive genetic and morphologic changes that form an aggressive tumor. Not having oxygen flow can make it very hard for a person to breathe and may cause their body and brain not to function correctly. Tumor suppressor genes are destructive growth regulators that turn off cellular multiplying to the normal cells by repairing DNA or introducing apoptosis. Apoptosis is the cell’s suicidal functions that destroys the cell…

    have demonstrated that the human HDM2 promoter is a target of the MEF transcriptional factor and the overexpression of MEF led to an increase in the Mdm2 protein (mice version of the human Hdm2), which in turn decreased the expression of the tumor-suppressor, p53, thereby augmenting transformation that may lead to leukemogenesis. Furthermore, the mutation commonly found in leukemia patients resulted in the delocalization of the NPM1 protein from the nucleolus to the…

    Another challenging approach is microRNA-based therapy that involves two strategies. The first aims to inhibit oncogenic miRNAs by using miRNA antagonists and the second strategy is miRNA replacement, which involves the reintroduction of a tumor-suppressor miRNA mimetic to restore a loss of…

    risk factors. Research into the cause of bone cancers has not yet been completed. Bone cancer occurs when a mutation throws off cells’ balance of oncogenes, genes that promote division, and tumor suppressor genes, genes that limit division. If the oncogenes are not kept in check by the tumor suppressor genes the cell will divide repeatedly, becoming a…

    tumor cells which effect immune system dynamics are; first, tumors can lose antigen expression which obstructs production of antibodies allowing the tumours free-reign. Second, tumour cells can generate suppressor T-cells which essentially turns the body’s own defense system against itself as suppressor T-cells subdue the antigen response of B-cells and other T-cells. Third, tumour cells utilizes Fas-L, a protein that when attached to initiates cell apoptosis or cell suicide, on activated…

    Breast cancer is the second leading cause of cancer-related deaths in Canadian women, with the majority of these deaths resulting from metastasis of cancer to other tissues. In 2015, an estimated 25,000 Canadian women will be diagnosed with breast cancer and 5,000 will suffer from cancer-related deaths. When breast cancer is isolated to the breast tissue, cure rates surpass 90%; nonetheless, as cancer cells settle into the adjacent or distant tissues, long-term survival is markedly declined. The…

    degree of immune tolerance to the transplant does develop. Several concepts have been postulated to explain the development of partial tolerance. They include clonal deletion and the development of anergy in donor specific lymphocytes, development of suppressor lymphocytes, or factors that down-regulate the immune response against the graft. Other hypotheses include the persistence of donor-derived dendritic cells in the recipient that promote an immunologically mediated chimeric state between…

    Genetic Susceptibility Genetic susceptibility plays a role in many types of cancer and other diseases. Finding the genes involved in susceptibility to diseases can be important for risk management. It known as inherited risk of developing a disease. Having a genetic predisposition for a disease does not mean that people will get that disease, but the patient risk may be higher than that of the general population. For example, some people with a predisposing genetic variation will never get the…
