Project description:In this study, we sought to establish the usefulness of LCM on cDNA microarray analysis. We reported that LCM samples improved the sensitivity of detection of differentially expressed genes over conventional bulk tissue analysis. We also provided the new information of chemokine and its receptor interaction within psoriatic lesional skin. For the comparison of gene expression patterns between single and double amplification techniques, total RNA was extracted from blocks of paired lesional and non-lesional psoriatic skin biopsies from four patients. For LCM experiment, total RNA was extracted from sliced tissue sections of paired lesional and non-lesional psoriatic skin biopsies from three patients.
Project description:Investigation of gene expression in biopsies from psoriasis patients before and after adalimumab treatment. Paired biopsies from non-lesional and lesional before treatment start and from psoriatic skin four and 14 days treatment start were included.
