Description
Mitochondrial biogenesis is under the control of two different genetic systems: the nuclear genome (nDNA) and the mitochondrial genome (mtDNA). mtDNA is a circular genome of 16.6 kb encoding 13 of the approximately 90 subunits that form the respiratory chain, the remaining ones being encoded by the nuclear genome (nDNA). Eukaryotic cells are able to monitor and respond to changes in mitochondrial function through alterations in nuclear gene expression, a phenomenon first defined in yeast and known as retrograde regulation. With this experiment we aimed to identify the set of nuclear genes that significantly change their expression level in response to depletion of mtDNA.

Description
Here, seeking to gain insight into the array of transcripts engaged with miRNAs in human brain, we performed HITS-CLIP to profile transcriptome-wide Ago2:RNA interactions in a panel of eleven post-mortem adult human brain samples harvested from adult motor cortex and cingulate gyrus, regions associated with movement and psychiatric disorders . Overall design: High-throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP) Eleven post-mortem adult human brain tissues were subjected to ultraviolet radiation to crosslink proteins with nucleic acids, and HITS-CLIP was performed as previously described by Chi et al Nature. 2009 Jul 23;460(7254):479-86 using an anti-Ago2 polyclonal antibody and some additional modifications.

Description
The study of the roles of macrophages in the microenvironment of cancer cells (tumor-associated macrophages, TAM) has gained deep insight over the recent years. Here, we describe gene expression profile of chronic lymphocytic leukemia (CLL)-associated macrophages, also called nurse-like cells (NLC), derived from in vitro co-cultures system.

Description
We examined context specific function of BRD4 in promoting lineage specific gene expression and show that BRD4 is essential for osteoblast differentiation. Overall design: We performed mRNA sequencing from hFOB cells (undifferentiated and differentiated for 5 days into osteoblastic lineage) following BRD4 inhibition by JQ1 or siRNA mediated depletion. The mRNA-Seq includes namely 7 conditions: undifferentiated hFOBs treated with DMSO or non-targeting control siRNA (siCNTR), differentiated hFOBs with DMSO or siCNTR treatments; differentiated hFOBs treated with JQ1 or two siRNAs against BRD4 (#3 & #4). The libraries were performed in triplicates.

Description
Dysfunctions in mitochondria dynamics and metabolism are common pathological processes associated with Parkinson's disease (PD). Recently, it was shown that an inherited form of PD and dementia is caused by new mutations in the OPA1 gene, which encodes for a key player of mitochondrial fusion and structure. iPSC-derived neural cells from these patients exhibited severe mitochondrial fragmentation, respiration impairment, ATP deficits and heightened oxidative stress. Reconstitution of normal levels of OPA1 in PD-derived neural cells normalized mitochondria morphology and function. OPA1 mutated neuronal cultures showed reduced survival in vitro. Intriguingly, selective inhibition of necroptosis effectively rescued this survival deficit. Additionally, dampening necroptosis in MPTP treated mice protected from DA neuronal cell loss. This human iPSC-based model captures both the early pathological events in OPA1 mutant neural cells and the beneficial effects of blocking necroptosis, highlighting this cell death process as a promising therapeutic target for PD. Overall design: 3 replicates for control and 3 replicates for OPA1 F38D mutant cells

Description
The cellular origin of Ewing tumor (ET), a tumor of bone or soft tissues characterized by specific fusions between EWS and ETS genes, is highly debated. Through gene expression analysis comparing ETs with a variety of normal tissues, we show that the profiles of different EWS-FLI1-silenced Ewing cell lines converge toward that of mesenchymal stem cells (MSC). Moreover, upon EWS-FLI1 silencing, two different Ewing cell lines can differentiate along the adipogenic lineage when incubated in appropriate differentiation cocktails. In addition, Ewing cells can also differentiate along the osteogenic lineage upon long-term inhibition of EWS-FLI1. These in silico and experimental data strongly suggest that the inhibition of EWS-FLI1 may allow Ewing cells to recover the phenotype of their MSC progenitor.
