Identification and characterization of nuclear matrix protein[s] and assessment of its usefullness for early diagnosis of bladder cancer

The highest incidence rates of bladder cancer are generally found in industrially developed countries, particularly North America and Western Europe, and areas associated with endemic schistosomiasis, including parts of Africa and the Middle East. The appropriate treatment of patients with bladder cancer mandates early detection and regular follow up for recurrences. Currently, cystoscopy is the standard method for diagnosing and monitoring bladder cancer recurrence, but it is an invasive and relatively costly technique, and may sometimes be inconclusive, particularly in cases of cystitis. Western blot and specific immunoglobulin-G antibody were used to identify the urinary NMP marker. Urine samples from 123 patients with bladder cancer and 50 controls were evaluated using the developed SDS-PAGE, Western blot and ELISA. The NMP marker was identified in the urine of patients with bladder cancer at 52 kDa [NMP- 52] by SDS-PAGE, Western blot and ELISA. In addition, the NMP-52 tumor marker was not detected in the urine of patients. Detecting the urinary NMP-52 marker using SDS-PAGE, Western blot and ELISA, would be helpful in the rapid diagnosis of bladder cancer

Angiotensin converting enzyme I/D polymorphism in Egyptian patients with type 2 diabetes mellitus

The deletion [D] allele of the angiotensin-I converting enzyme [ACE] is associated with higher ACE activity, it has been studied in various populations in relation lo hypertension and type 2 diabetes mellitus [DM] with contradictory results. The objective of this study was to determine the ACE insertion/deletion polymorphism, genotype distribution in Egyptian patients with type 2 DM and to evaluate the possible association of ACE insertion/deletion polymorphism with hypertension in diabetic patients. A total of 48 patients with type 2 DM, 23 of them had hypertension and 21 healthy subjects age and sex matched with the patients, as control group were included in this study. Genotyping was performed by polymerase chain reaction [PCR]. The frequency of DD genotype was significantly higher in diabetic patients compared to controls [p=0.008]. The DD genotype [Vs DI and II genotypes] was associated with increased risk of diabetes [OR: 3.647, 95% CI: 1.235-10.773, p=0.016] and the D allele was more frequent in diabetic patients and was associated with increased risk of diabetes [OR: 3.939, 95% CI: 1.782-8.709, p<0.001]. No significant difference in genotype distribution or allele frequency was detected between diabetic patients with and without hypertension. We can conclude that a significant association between ACE gene I/D polymorphism and type 2 DM is present in Egyptian patients and the D allele is associated with increased risk for type 2 DM
