Project description:Investigation of differences in gene expression between two strains of the planarian Schmidtea mediterranea. The sexual strain are cross-fertilizing hermaphrodites with reproductive organs that develop post-embryonically and the asexual strain reproduces exclusively by transverse fission and fail to develop reproductive organs. A two chip study using total RNA recovered from asexual and sexual animals. Each chip measures the expression level of 16,797 ESTs from S. mediterranea with 10 60-mer probe pairs (PM/MM) per gene, with two-fold technical redundancy.

Transcriptome analysis reveals strain-specific and conserved stemness genes in Schmidtea mediterranea

Project description:The transcriptome of the planarian Schmidtea mediterranea is not well characterized. We have used RNA-Seq to characterize the transcriptome in both sexual and asexual strains of S. mediterranea from both untreated and irradiated animals. Moreover, we have performed RNA-Seq on RNA purified from FACS sorted neoblasts and differentiated cells. Together these studies expand our understanding of the planarian transcriptome and have identified strain-specific, neoblast-specific, and conserved transcripts.

Expression analyses of nanos(RNAi) and control(RNAi) Schmidtea mediterranea

Project description:Investigation of whole genome gene expression level changes in nanos(RNAi) Schmidtea mediterranea, compared to control animals. nanos(RNAi) animals are devoid of germ cells The samples analyzed in this study are further described in Wang, Y., Stary, JM., Wilhelm, JE. and Newmark, PA. 2010. A eight chip study using total RNA recovered from asexual nanos(RNAi), asexual control, juvenile sexual nanos(RNAi), and juvenile sexual control animals. Each chip measures the expression level of 16,797 ESTs from S. mediterranea with 10 60-mer probe pairs (PM/MM) per gene, with two-fold technical redundancy.
