Redistribution of Free- and Cell-Surface-Bound DNA in Blood of Benign and Malignant Prostate Tumor Patients
نویسندگان
چکیده
A direct correlation between the concentration of cell-free and cell-surface-bound circulating DNA (cfDNA and csbDNA, respectively) was demonstrated. Based on an inverse correlation between blood plasma DNase activity and the cfDNA concentration, blood DNases are supposed to regulate the cfDNA concentration. However, no correlation was found between the DNase activity in blood plasma and the csbDNA concentration, indicating that blood DNases are not involved in csbDNA dissociation from the cell surface. The possibility of DNA redistribution between cfDNA and csbDNA indicates that the total pool of circulating DNA (cfDNA + csbDNA) should be used for a correct analysis of marker DNA concentrations and data standardization.

Association Study of miR-124-a-3 Gene rs34059726 Polymorphism with Prostate Cancer in Gonbad Kavous
Background: MiRNAs are one of the most important genetic regulators that regulate more than 50 percent of the human genome. MiR-124-a-3 is a tumor suppressor miRNA which its expression dramatically reduced in prostate cancer tumor cells. Since miRNA binding to the transcript of target genes by seed sequence, any mutations and changes in this region could be effective on its performance and iden...
متن کاملStudy of Correlation between Prostate Specific Antigen and Matrix Metalloproteinase-2 Activity in Benign and Malignant Prostate Hyperplasia
There are emerging data on novel tumor markers such as matrix metalloproteinase-2 (MMP-2 or gelatinase-A), which play a key role in tissue invasion and metastasis. We designed an investigation to assess the usefulness of MMP-2 activity as compared to prostate specific antigen (PSA) in cancer staging process. We have analyzed the circulating form of MMP-2 in serum samples of patients suffering f...
متن کاملEvaluation of gene expression level of GPRC6A, E.cadherin and ZEB1 in prostate cancer in comparison to benign tissues
Background: Prostate cancer is currently the third malignant disease in Iran and fifth common cancer worldwide. The aim of this study was to determine the expression of GPRC6A, E.cadherin, and ZEB1 genes in prostate cancer in comparison with benign tumor. Since early detection of cancer plays an important role in treatment, this study aims to identify the role of GPRC6A, E.cadherin and ZEB1 gen...

Background: Prostate cancer is the second form of cancer among men worldwide. For early cancer detection, we should identify tumors in initial stages before the physical signs become visible. The present study aims to evaluate the diagnostic value of cell-free DNA (cfDNA), its comparison with prostate-specific antigen (PSA) level in prostate cancer screening and also in patients with localized ...
متن کاملClear cell sarcoma of the hand: a case of malignant melanoma of soft parts
A case is reported with clear cell sarcoma (CCS) of the hand. Early diagnosis of clear cell sarcoma is always difficult due to its slow growing nature, benign clinical appearance, lack of pigmentation in most cases, and relatively young age of patients which make it to clinically appear as a benign soft tissue tumor. We report a case of clear cell sarcoma of hand in a 56 year old male with a no...
