Download file to see previous pages This research paper is focused on basic attempts of TAAs identification and the role they play for different types of tumors. TAAS vs Cancer The important role of tumor associated antigens (TAAs) can be explained in the following way: they are present in cancer cells and can cause a powerful antitumor immune response among patients with lung carcinoma or any other type of cancer. There are the following types of identified TAAs: MAGE and BAGE families, gp 100, SART-1, tyrosinase, MUC-1 and others (Akimov, 2004). They are used by immunotherapy for treating cancer. Nevertheless, there is no satisfactorily level of this kind of treatment (Danussi, Coslovi, Campa, Mucignat, Spessotto, Uggeri, Paoletti, Colombatti, 2009). Therefore, there is a need to focus more on identification of TAAs and available TAAs to target. There is an option to identify TAAS with the help of “serological analysis of recombinant c DNA expression libraries (SEREX), using tumor mRNA and autologous serum from a patients with NSCLC. SEREX analysis of a range of different human tumor types has identified a number of tumor antigens with diagnostic and therapeutic potential” (Akimov, 2004). Different approaches are being currently developed and it is of high importance for the modern researchers and scientists to identify relevance of TAAs in dealing with different types of cancer. ...
MAGE-3 is the most broadly known CT antigen, which is the first and foremost target for cancer vaccines (Slovin, Ragupathi, Fernandez, Diani, Jefferson, Wilton, Kelly, Morris, Solit, Clausen, Livingston, Scher, 2007). On the basis of different researchers and laboratory experiments, the scientists are looking for a correlation between TAAs identification and assessment of patient’s cell’s response to TAA’s. Strategies for vaccine development have been correlated with identification and management of TAAs. Highly attractive targets for cancer vaccines are cancer testis (CT) antigens. These antigens are applicable for different forms of various human cancers. In accordance with current data, “MAGE antigens are expressed in about 40% of non-small-cell lung cancer (NSCLC) cases [8]. In summary, this analysis provided further insights in the immunogenicity of lung cancer with respect to antigen specific humoral and cellular immune responses” (Vonderheide, 2002). There is a clear tendency to find out universal antigens. The most serious preventive factor for a proper searching for TAAs is that different patients with different forms of cancer have not been treated by a so-called “universal” TAAs. Therefore, there is a need for universal tumor-associated antigens. Consequently, the modern scientists and researchers are focused on searching for a new type of TAAs dealing with different types of tumor. One of the most optimal methods is “epitope deduction”, which begins with a number of database analyses focused on appropriate gene products’ selection and further scanning of the deduced protein sequence for peptides, known as MHC binding motifs (Vonderheide, 2002). This method is independent from the existence of an innate anti-tumor T-cell ...Download file to see next pagesRead More

Identification of novel human cancer-specific antigens

...research in the search for effective cancer vaccines has produced cancer/testis antigens such as MAGE, GAGE, and NY-ESO-1 which are currently undergoing clinical trials (Mashino et al. 2001; Bowlus, 2007; Gierstoff and Ditzel, 2008). Each year more cancer/testis antigens are being identified, creating more opportunities for research and increasing the chances of developing cancer vaccines that can be used not only for treatments, but for prevention as well (Jager, Jager, and Knuth, 2002). Also, research on cancer/testis antigens has brought to light important discoveries...

...?Tumour Associated Antigens Tumour antigens are antigenic proteins produced by tumour cells. These antigens are ified into two broad es, Tumour- Specific Antigens (TSA) and Tumour- Associated Antigens (TAA). TSA are unique to tumour cells only while TAA are in both tumour cells and normal body cells (Ghaffar & Nagarkatti 2010). This paper explains the antigenic extent in which the knowledge of...

Exercise in Cancer patients

...?Deryl Felder October 15, Professional Foundations of Exercise Science Exercise in Cancer Patients Introduction While the diagnoses among chronic diseases are becoming more prevalent among Americans today, it is imperative for our society to continue researching the most effective methods in treating and preventing these various diseases. Cancer, being one of the highest causes of death in the U.S today, is a chronic disease that needs to be further assessed in how it can be successfully treated. In the past, many believed the best treatment for cancer patients included rest and reduced physical activity; however, today, as more research...

Individualising Cancer Patients Treatment Plan

..., bearing in mind the patient's type of cancer, its stage, and all the treatment options available and the probability of these treatments working under the given circumstances. The oncologist should discuss with each patient individually about the nature of their cancer. They could use patient education materials and websites to supplement their knowledge about the various types of tumours. 5 After establishing the exact nature of the tumours, the oncologist should start treating the patient with primary therapy. Primary therapy may involve surgery, radiation,...

Tumour Immunotherapy

...with viruses and tumour specific differentiation antigens (Waldmann, 269). One method of defining cancer associated antigens is to define antigens recognized by the tumour bearing host by identifying the circulating antibodies developed against tumour antigens in the host. Technique of serological identification by recombinant expression cloning called SEREX is used to identify circulating IgG that are specific to the tumour antigens. Screening cDNA libraries from tissues using tumour...

Tumour markers

.... Therefore, it is important to understand that it is the quantity and not just the presence of these compounds that must be considered in assessing the clinical use of tumour markers. Tumour markers are usually proteins (structural proteins and enzymes), cell-surface carbohydrate antigens, cellular receptors, and genes, which are detected in tissue, urine, and blood samples. Markers can be specific for a certain type of cancer, while there are markers that are common for different cancer types. Some markers also show increased concentration in the tissues and body fluids even in the absence of cancers....

Pain Management and Cancer Patients

...defined as “An unpleasant sensory and emotional experience associated with actual or potential tissue damage, or described in terms of such damage” by the International Association for the Study of Pain (IASP Pain Terminology, 1994). It is a subjective experience while it is also a complex perception produced by the brain and the nervous system which basically signals the occurrence of actual or potential tissue damage. The term “nociception” is generally used to refer to the perception of pain. Pain has physical as well as emotional consequences, and, at its worst, the potential to curtail productivity, and the sense of well-being. The presence of uncontrolled pain in...

The field of developing antigen-specific cancer vaccine is in early steps (Karbach, et al., 2010). Future aspects of cancer testis antigen Findings indicate that expression of CTAs often depict marked specificity for tumor cells. For early detection and target specific gene therapy or treatment of cancer, the tumor markers are used to target tumors.

Alleviating Depression in Cancer Patients

..., difficulties in interpersonal relationships. These problems should be taken into serious consideration when assessing and managing depressed cancer patients. On their study, Wells et al. (2013) found out that there is the need for psycho-educational approaches during the early cognitive treatment. This is important is curbing some of the negative perceptions that may occur from antidepressant. Beside clinical depression, the antidepressants can be effective in dealing with or treating depressive symptoms (Laoutidis & Mathiak, (2013). A lot of research has been carried out to determine the groups and number of patients most affected by depression. One...
