Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
Transient expression of two factors, or from Oct4 alone, resulted in efficient generation of human iPSCs. The reprogramming strategy described revealed a potential transcriptional signature for human iPSCs yet retaining the gene expression of donor cells in human reprogrammed cells free of viral and transgene interference.

Description
Long noncoding RNAs (lncRNAs) have appeared to be involved in the most diverse cellular processes through multiple mechanisms. Here we describe a previously uncharacterized human lncRNA, CONCR (cohesion regulator noncoding RNA), transcriptionally activated by MYC, which is upregulated in multiple cancer types. The expression of CONCR is cell cycle-regulated, and it is required for cell cycle progression and DNA replication. Moreover, cells depleted of CONCR show severe defects in sister chromatid cohesion, suggesting an essential role for CONCR in cohesion establishment during cell division. CONCR interacts with and regulates the activity of DDX11, a DNA-dependent ATPase and helicase involved in DNA replication. These findings suggest a novel mechanism of action for CONCR in the modulation of DDX11 enzymatic activity, unveiling the direct involvement of a lncRNA in the establishment of sister chromatid cohesion.

Description
We report the application of high-throughput sequencing to performed the p53 regulated trancriptome in HCT116 colon cancer cells treated with the DNA damage 5FU. To study the direct targets of p53 we performed ChIP-seq to deterrmined the p53 biding sites and associated with the expression levels. With this study we identified the new genomic regions regulated by p53 and with special attention in those regions that are significally expressed by DNA damage and and are non- coding.

Description
A rare complication of multiple myeloma is a secondary extramedullary involvement, and the skin is one of the possible sites, due to the physiological homing of plasma cells (PCs) into the skin. The article reports a case of a relapsed refractory MM patient, who developed a cutaneous localization after 16 months from the diagnosis under Bortezomib treatment without a leukemic phase. Patient was refractory to Bortezomib. We analyzed the gene expression profiles, the immunophenotypic and immunohistochemistry profiles of MM cells across the course of the disease at the bone marrow and skin localization. Data obtained were further expanded by an immunohistochemistry analysis on selected molecules in a large cohort of MM patients with cutaneous localization. In particular we focused on the expression of chemokines and chemokine receptors involved in the PC skin homing.

Description
We performed genomic and transcriptomic analysis of seven cases of molecular Burkitt lymphoma (mBL) developed in immunosuppressed patients who underwent solid organ transplantation. Interestingly, three cases (43%) were MYC-translocation-negative and revealed the 11q-gain/loss aberration recently identified in 3% of mBL developed in immunocompetent hosts.1 Based on array CGH data, minimal gain and loss regions of 11q (MGR/~4Mb and MLR/~13.5Mb, respectively) were defined and integrative genomic and transcriptomic analysis identified 35 differentially expressed genes, when compared with classic BL. All 16 MGR-dysregulated genes were upregulated, including cancer related USP2, CBL and PAFAH1B2. As expected, all 19 MGL-dysregulated genes were downregulated and two of them, TBRG1 and EI24, are potential tumor suppressor genes. Interestingly, the vast majority of dysregulated 11q23-q25 genes are involved in the MYC and TP53 networks. We hypothesize that the 11q-gain/loss aberration represents a molecular variant of t(8q24/MYC) and affects the same pathological pathways as the MYC oncogene.

Description
Despite widespread knowledge that bone marrow-resident breast cancer cells (BMRCs) affect tumor progression, signaling mechanisms of BMRCs implicated in maintaining long-term dormancy have not been characterized. To overcome these hurdles, we developed a novel experimental model of tumor dormancy employing circulating tumor cells (CTCs) derived from metastatic breast cancer patients (de novo CTCs), transplanted them in immunocompromised mice, and re-isolated these cells from xenografted mice bone marrow (ex vivo BMRCs) and blood (ex vivo CTCs) to perform downstream transcriptomic analyses.
