A multilingual assessment of melanoma information quality on the Internet.

This study aims to assess and compare melanoma information quality in Hungarian, Czech, and German languages on the Internet. We used country-specific Google search engines to retrieve the first 25 uniform resource locators (URLs) by searching the word "melanoma" in the given language. Using the automated toolbar of Health On the Net Foundation (HON), we assessed each Web site for HON certification based on the Health On the Net Foundation Code of Conduct (HONcode).

Comparison of stress-induced PRINS gene expression in normal human keratinocytes and HaCaT cells.

Psoriasis is a chronic inflammatory skin disease that affects approximately 2-4% of the population. We recently described a novel non-coding RNA, psoriasis susceptibility related RNA gene induced by stress (PRINS), that was overexpressed in non-lesional psoriatic epidermis, and its expression was induced by various stress factors such as serum starvation, contact inhibition, ultraviolet (UV)-B irradiation, viral infection and translational inhibition in HaCaT cells. In the present work we set out to compare the stress and microbial agent-induced PRINS expression in normal human keratinocytes (NHKs) and HaCaT cells.

Identification and characterization of a novel, psoriasis susceptibility-related noncoding RNA gene, PRINS.

To identify genetic factors contributing to psoriasis susceptibility, gene expression profiles of uninvolved epidermis from psoriatic patients and epidermis from healthy individuals were compared. Besides already characterized genes, we identified a cDNA with yet unknown functions, which we further characterized and named PRINS (Psoriasis susceptibility-related RNA Gene Induced by Stress). In silico structural and homology studies suggested that PRINS may function as a noncoding RNA.
