Affymetrix Human Genome U133 Plus 2.0 Array (hgu133plus2)
Description
The immortalized human urothelial cell line, UROtsa, was transformed in six parallel cultures with continual passaging in1 M Cd+2 until the cells were able to attain the ability to form colonies in soft agar and subcutaneous tumors in nude mice. The gene expression profiles between cadmium-transformed and control samples were compared and the differentially expressed genes were identified.

Description
Dysregulated oncogenic serine/threonine kinases play a pathological role in diverse forms of malignancies, including multiple myeloma (MM), and thus represent potential therapeutic targets. Here, we evaluated the biological and functional role of p21-activated kinase 4 (PAK4), and its potential as a new target in MM for clinical applications. PAK4 promoted MM cell growth and survival via activation of MM survival signaling pathways, including the MEK-ERK pathway. Furthermore, treatment with orally bioavailable PAK4 allosteric modulator (KPT-9274) significantly impacted MM cell growth and survival in a large panel of MM cell lines and primary MM cells alone and in the presence of bone marrow microenvironment. Intriguingly, we have identified FGFR3 as a novel binding partner of PAK4 and observed significant activity of KPT-9274 against t(4;14)-positive MM cells. These data support PAK4 as an oncogene in myeloma, and provide the rationale for the clinical evaluation of PAK4 modulator in myeloma.

Description
E2Fs are regulators of the cell cycle and are involved in development. In this study we examine transcriptional changes occurring the liver in E2f1 (1KI) and E2f3b (3bKI) knock in mice. These mice have E2f1 or E2f3b knocked into the E2F3a locus resulting in loss of E2f3a and expression of E2f1 or E2f3b from the E2f3a locus as originally described In Tsai et. al., Nature 2008.

Description
A critical step in regeneration is recreating the cellular identities and patterns of lost organs long after embryogenesis is complete. In plants, perpetual (indeterminate) organ growth occurs in apical stem cell niches, which have been shown to re-establish quickly when damaged or removed (1,2). Here we ask whether the machinery of perpetual organ growth, stem cell activity, is needed for the phase of regeneration that leads to replenishing lost cell identities and patterning, or, whether organ re-establishment enlists a wider group of pluripotent cells. We adapt a root tip regeneration system to Arabidopsis that permits us to assess the molecular and functional recovery of specific cell fates during organ regeneration. These results suggest a rapid restoration of missing cell fate and function in advance of the recovery of stem cell activity. Surprisingly, plants with mutations that fail to maintain stem cell activity were able to re-pattern their distal tip and re-specify lost cell fates. Thus, although stem cell activity is required to resume indeterminate growth (3), our results show it is not necessary for cell re-specification and patterning steps. This implies a regeneration mechanism that coordinates patterning of the whole organ, as in embryogenesis, but is initiated from different starting morphologies. 1. Feldman, L. J.

Description
Mesenchymal stromal cells (MSCs) sense and modulate inflammation and represent potential clinical treatment for immune disorders. However, many details of the bidirectional interaction between MSCs and the innate immune comaprtment are still unsolved. Here we describe an unconventional but functional interaction between pro-inflammatory classically activated macrophages (M1M) and MSCs, with CD54 playing a central role. CD54 was upregulated and enriched specifically at the contact area between M1M and MSCs. Moreover, the specific interaction induced calcium signaling and increased the immunosuppressive capacities of MSCs dependent on CD54 mediation. Our data demonstrate that MSCs can detect an inflammatory microenvironment via a direct and physical interaction with innate immune cells. This finding opens new perspectives for MSC-based cell therapy.
