Description
RNA seq was performed comparing SC-specific Dicer mutants with SC-specific Lin28B transgenics to obtain an unbiased list of potentially de-regulated miRNA target candidates. Overall design: total RNA from sciatic nerves of P1 Dicer mutants, P1 Lin28 transgenics and their respective controls was used to perform RNA sequencing analysis.

Description
Philadelphia-like B-cell precursor acute lymphoblastic leukemia (Ph-like ALL) is characterized by distinct genetic alterations and inferior prognosis in children and younger adults. The purpose of this study was the genetic and clinical characterization of Ph-like ALL in adults. Among 207 adult B-cell precursor ALL patients, 26 (13%) were classified as Ph-like using Affymetrix microarrays. The incidence of this subtype was 25% among 105 B-cell precursor ALL patients negative for BCR-ABL1 and MLL-translocations (B-other). All patients with IgH-CRLF2 translocation (38% vs 0%; p=0.002) or mutations in JAK2 (44% vs. 0%; p<0.001) were exclusively found in the Ph-like subgroup. Clinical and outcome analyses were restricted to patients treated within GMALL trials 06/99 and 07/03 (n=107). The complete remission (CR) rate after induction was 100% for Ph-like (n=19) and B-other patients (n=40). After induction, significantly fewer Ph-like patients reached molecular CR (33% vs 79%; p=0.01). At 5 years, the Ph-like ALL subgroup had a lower probability of continuous CR (24% vs 62%; p<0.001) and overall survival (22% vs 64%; p=0.006) compared to B-other ALL patients. Subsequent analysis led to a clinically applicable algorithm identifying this patient subset with a specificity of 100%. Our study is the first to demonstrate that the profile of genetic events in adult Ph-like ALL resembles pediatric Ph-like ALL and differs from B-other ALL. The Ph-like phenotype associates with inferior outcomes in intensively treated adult ALL patients. Ph-like adult ALL should be recognized as a distinct, high-risk entity and further research on improved diagnostic and therapeutic approaches is needed.

Description
To validate the suitability of two commonly used colorectal cancer cell lines, DLD1 and SW480, as model systems to study colorectal carcinogenesis, we treated these cell lines with -catenin siRNA and identified -catenin target genes using DNA microarrays. The list of identified target genes was compared to previously published -catenin target genes found in the PubMed and the GEO databases.

Description
Constitutive activation of EGFR- and NF-kB-dependent pathways is a hallmark of cancer, yet signaling proteins that connect both oncogenic cascades are poorly characterized. Here we define KIAA1199 as a BCL-3- and p65-dependent gene in transformed keratinocytes. KIAA1199 expression is enhanced upon human papillomavirus (HPV) infection and is aberrantly expressed in clinical cases of cervical (pre)neoplastic lesions. Mechanistically, KIAA1199 binds Plexin A2 and protects from Semaphorin 3A-mediated cell death by promoting EGFR stability and signaling. Moreover, KIAA1199 is an EGFR-binding protein and KIAA1199 deficiency impairs EGF-dependent Src, MEK1 and ERK1/2 phosphorylations. Therefore, EGFR stability and signaling to downstream kinases requires KIAA1199. As such, KIAA1199 promotes EGF-mediated epithelial-mesenchymal transition (EMT). Taken together, our data define KIAA1199 as an oncogenic protein induced by HPV infection and constitutive NF-kB activity that transmits pro-survival and invasive signals through EGFR signaling.
Publication Title
NF-κB-induced KIAA1199 promotes survival through EGFR signalling.

Description
Depending on the tumor type IB kinase (IKK) can act as tumor promoter or tumor suppressor in various malignancies. Here we demonstrate a key function of IKK in the suppression of a tumoricidal microenvironment during intestinal carcinogenesis. Mice deficient in IKK kinase activity are largely protected from intestinal tumor development that is dependent on the enhanced recruitment of IFN expressing M1-like myeloid cells. In IKK mutant mice M1-like polarization is not controlled in a cell autonomous manner but depends rather on the interplay of both IKK mutant tumor epithelia and immune cells.
Publication Title
IKKα promotes intestinal tumorigenesis by limiting recruitment of M1-like polarized myeloid cells.
