Enhanced Tumor Growth In Uv-Irradiated Skin Is Associated With An Influx Of Inflammatory Cells Into The Epidermis, Ronald Sluyter, Gary M. Halliday

UV radiation causes a number of cellular changes within the skin which play a role in tumor outgrowth, including immunosuppression and production of growth-enhancing cytokines, Both of these enable tumors to grow but their relative importance in carcinogenesis is poorly defined. In this study, C3H/HeN mice were exposed to a single inflammatory dose of 410 mJ/cm(2) UVB radiation (plus 100 mJ/cm2 UVA radiation) followed by the inoculation of a regressor squamous cell carcinoma into or the painting of oxazolone onto the treated skin. Tumors transplanted 2 or 3 but not 4 days after irradiation had a significantly higher growth rate …

cDNA sequence analysis of the X-linked glucose-6-phosphate dehydrogenase (G6PD) gene has shown a base difference between two subspecies of the kangaroo, Macropus robustus robustus (wallaroo) and M. r. erubescens (euro). A thymine residue in the wallaroo at position 358 in exon 5 has been replaced by a cytosine residue in the euro, which accounts for the previously reported electrophoretic difference between the two subspecies. This base difference allowed use of the Single Nucleotide Primer Extension (SNuPE) technique to study allele-specific expression of G6PD at the transcriptional level. We began by examining G6PD expression in somatic cells and observed complete paternal …

The phosphoglucomutase (PGM)-encoding gene of Bordetella bronchiseptica is required for lipopolysaccharide (LPS) biosynthesis. An insertion mutant of the wild-type B. bronchiseptica strain BB7865 which disrupted LPS biosynthesis was created and characterized (BB7865pgm). Genetic analysis of the mutated gene showed it shares high identity with PGM genes of various bacterial species and forms part of an operon which also encompasses the gene encoding phosphoglucose isomerase. Functional assays for PGM revealed that enzyme activity is expressed in bothbvg-positive and bvg-negative strains ofB. bronchiseptica and is substantially reduced in BB7865pgm. Complementation of the mutated PGM …

Purpose: The clusterin gene encodes a multi-functional protein that has been identified in different tissues, including a number of different eye tissues, primarily in the mouse and to a much lesser extent in humans. Clusterin has been implicated in a number of cellular processes such as lipid transport, membrane integrity, apoptosis, and neurodegeneration, all of which could be important to the biology of the eye. In the current communication, we provide data that confirms the expression of clusterin in a number of different human eye tissues and establishes the expression profile of this gene in monkey derived eye tissues. The …
