View SamplesWe have generated a mouse model for tumor initiation carrying a mutation in APC and lacking IKKa in intestinal epithelial cells. IKKa-deficient intestinal cells primarily failed to generate adenomas, and the few adenomas arising in this background displayed a significant reduction in cell proliferation. Using an in vitro model for intestinal tumoroids (derived from adenoma initiating cells), we have performed RNA sequencing of wild type and IKKa-deficient intestinal tumoroids. This has demonstrated that epithelial IKKa controls transcription of stem cell-related genes and genes associated with proliferation and apoptosis. Overall design: RNA sequencing of IKKa WT and KO tumoroids, done in triplicates
IKKα is required in the intestinal epithelial cells for tumour stemness.

View SamplesClassical regeneration experiments in insects have demonstrated an important role for imaginal tissues (also called discs, the larval tissues that give rise to the adult appendages) in coupling tissue growth, maturation and patterning during development We used the rotund-Gal4 driver (Rn>) for disc-targeted silencing of the avalanche gene (avl; Rn>avl-RNAi), encoding a syntaxin that functions in the early endocytic machinery (H. Lu, D. Bilder, Nat Cell Biol 7, 1232; Dec, 2005). Rn>avl-RNAi discs reach near to normal size after 5 days of development, and then undergo unrestricted neoplastic growth. We were interested in identifying genes showing differential expression profiles in control and in neoplastic growth. We identified dilp8 as one of the most differentially expressed gene in control and Rn>avl-RNAi discs.
Secreted peptide Dilp8 coordinates Drosophila tissue growth with developmental timing.

View SamplesSeveral studies demonstrated IgVH mutation status and ZAP-70 expression as the most relevant prognostic markers in CLL, suggesting the separation of two patient subgroups: with good (MTZAP-70-) and poor prognosis (UMZAP-70+). We determined gene expression of B cells in 112 CLL patients divided into three classes: the first with IgVHMT and ZAP-70-, the second with IgVHUM and ZAP-70+, and the third included both IgVHUM ZAP-70- and IgVHMT ZAP-70+. We found LPL, AGPAT2, MBOAT1, CHPT1, AGPAT4, PLD1 genes encoding enzymes involved in lipid (glycerolipid/glycerophospholipid) metabolism overexpressed in UMZAP-70+. In addition, this study demonstrates the role of ARSD, a gene belonging to the sphingolipid metabolism, as a new gene significantly overexpressed in UMZAP-70+ in respect to MTZAP-70-. ARSD protein was found at significantly higher concentrations in UMZAP-70+ compared to MTZAP-70- CLL B cells and B cells from healthy individuals by Western blotting. Statistical analysis identified a strong correlation between ARSD and IgVH mutation status; ARSD protein level was associated with the requirement of therapy for CLL patients and for this purpose it is as good as IgVH mutational status. Our study highlights ARSD as a promising new prognostic factor in CLL and sphingolipid metabolism as a putative new biological mechanism in CLL.
Gene expression profiling identifies ARSD as a new marker of disease progression and the sphingolipid metabolism as a potential novel metabolism in chronic lymphocytic leukemia.
