Tumor protein D52 overexpression and gene amplification in cancers from a mosaic of microarrays.

The tumor protein D52 gene is increasingly recognized to be overexpressed in different cancer types, frequently through gain of the corresponding locus at chromosome 8q21.13. This review summarizes the literature identifying D52 overexpression and/or gene amplification in different cancers, as well as recent publications directly analyzing D52 functions.

Decline in neurophysiological function after 7 years in an adolescent diabetic cohort and the role of aldose reductase gene polymorphisms.

Objective: This 7-year longitudinal study examines the potential impact of aldose reductase gene (AKR1B1) polymorphisms on the decline of nerve function in an adolescent diabetic cohort.

Research Design And Methods: Patients with type 1 diabetes (n = 262) were assessed with three cardiovascular autonomic tests (heart rate variation during deep breathing, Valsalva maneuver, and during standing from a lying position) and pupillometry (resting pupil diameter, constriction velocity, and reflex amplitude), thermal, and vibration thresholds on the foot. Genotyping was performed for promoters (C-106T and C-12G), (CA)(n) dinucleotide repeats, and intragenic BamH1 polymorphism.

Genetic analysis of Pseudomonas aeruginosa isolates from the sputa of Australian adult cystic fibrosis patients.

Genetic investigations were carried out with 50 phenotypically selected strains of Pseudomonas aeruginosa from 18 patients attending an Australian cystic fibrosis (CF) center. The isolates were analyzed by restriction fragment length polymorphism (RFLP) analysis by pulsed-field gel electrophoresis (PFGE). Phylogenetic analysis of the macrorestriction patterns showed rates of genetic similarity ranging from 76 to 100%; 24 (48%) of the strains from 11 patients had greater than 90% similarity.
