Scholarly Open Access Journals In Diagnostic Biomarkers

Pancreatic cancer is one of the most aggressive human malignancies and ninth leading cause of cancer death in the world. Most patients diagnosed with pancreatic cancer die within 6 months, and only 4% survive 5 years after diagnosis. Early diagnosis and better treatments are desperately needed to improve the survival rate of pancreatic cancer patients. Pancreatic ductal adenocarcinomas, the majority of the exocrine pancreatic tumors, are thought to develop in a multistep process, involving a series of specific genetic mutations in each step. The comprehensive genetic analysis of 24 pancreatic cancers has shown 63 genetic alterations, and majority of which are point mutations. Interestingly, these alterations have been shown to affect 12 signaling pathways leading to pancreatic tumorigenesis. Because of nonspecific biomarkers for PDAC which lack specificity and sensitivity, high numbers of PDAC cases are diagnosed too late in the disease process for surgical resection to be an effective option. Even among the 10-20% of PDAC cases where surgical resection is an option, most patients ultimately die of recurrent or metastatic disease. In current investigation we were able to identify 41 proteins involved in oxidative stress response in pancreatic cancer and among them the presence of SOD2- mitochondrial, peroxiredoxin 2 and 4 and glutathione peroxidase was quite prominent, whereas these proteins were absent in control, suggesting aberrant regulation of redox homeostasis and stress adaptation in cancer cells. Mounting evidence suggests that, compared with their normal counterparts, many types of cancer cell have increased level of reactive oxygen species. Under persistent oxidative stress, many cancer cells become well-adapted to such stress and develop an enhanced, endogenous antioxidant capacity, which makes the malignant cells resistant to exogenous stress.

Open access scholarly journals are available online to the reader without financial, legal, or technical barriers. Scholarly open access journals are journals which are respected for the extensive research and information they provide about the point. The research often possesses refereed meaning that it is reviewed by other scientists who are knowledgeable about the theme of the article. Scholarly open access journals cite their sources using references or bibliographies
