Description
BACKGROUND: Mammalian microRNAs (miR) regulate the expression of genes relevant for the development of adaptive and innate immunity against cancer. Since T cell dysfunction has previously been reported in patients with renal cell carcinoma (RCC; clear cell type), we aimed to analyse these immune cells for genetic and protein differences when compared to normal donor T cells freshly after isolation and 35 days after in vitro stimulation (IVS) with HLA-matched RCC tumor cells.
Publication Title
miR-29b and miR-198 overexpression in CD8+ T cells of renal cell carcinoma patients down-modulates JAK3 and MCL-1 leading to immune dysfunction.

Description
Lamins, the major components of the nuclear lamina, have diverse functions in many cellular processes. Despite broad expression, lamins have been implicated in cell type-specific roles in development, aging and disease by regulating gene expression. Yet, due to the lack of in depth lineage-specific functional studies, it remains unclear whether or how lamins regulate cell type-specific functions. Using targeted knockout of lamin B1 in the olfactory sensory neuron lineage, we show that lamin B1 is not required for early stages of olfactory sensory neuron differentiation but is needed for formation of mature neurons that properly respond to odor stimulation. Lamin B1 mutant cells exhibited decreased expression of genes involved in mature neuron function, increased expression of genes atypical of the olfactory lineage and clustered nuclear pore distribution. These results demonstrate that the universally expressed lamin B1 regulates cell type-specific gene expression and terminal differentiation. Overall design: Transcriptome profiles were generated from sorted regenerated olfactory epithelium cells lacking Lamin B1 (Lmnb1) and control (heterozygous cells). Each sample is collected from one mouse. Data are from two experimental groups (G1,G2), each containing a control and a mutant sample. Different groups differ in treatment, parents, age and sex. Within a group, treatment, sample preparation, sequencing, animal sex, age, and parents are the same.

Description
The hallmark of IgA nephropathy (IgAN) is gross hematuria (GH) coinciding with or immediately following an upper respiratory or gastrointestinal tract infection and can represent the disease triggering event. Therefore, a whole genomic screening of IgAN patients during the GH was done to clarify the link between mucosal encountered antigens and the occurrence of glomerular hematuria. The modulated genes during GH show a clear involvement of the interferon signalling, antigen presenting pathway, and the immuno-proteasome. The gene characterizing cytotoxic effector lymphocytes (CX3CR1) implicated in vascular endothelial damage, was found up-regulated at both mRNA and protein level. In vitro antigenic stimulation of PBMCs on an independent set of IgAN patients and healthy blood donors (HBS) demonstrated that patients upregulate specifically CX3CR1 in an enhanced and dose dependant manner, while an expected down-regulation occurred in HBD. This enhanced activation occurred in both patients characterized by recurrent GH and by permanent microscopic hematuria (MH). We then analyzed glomerular fractalkine (FKN) expression, since this ligand is involved in the vascular gateway for CX3CR1+ cells towards the inflamed tissues. A significantly higher FKN expression on the capillary vessels and podocytes was found in recurrent GH patients compared to permanent MH, suggesting a predisposition for cytotoxic cell extravasation in recurrent GH patients.

Description
Albeit increased serum CK level and abnormal muscle histology are always present, boys with DMD are phenotipically indistinguishable from the normal ones at birth and, in their first years of life, acquire early motor milestones at normal times. A clear defect in muscle function becomes generally apparent by the end of the second year. As the disease is typically diagnosed between the ages of 3 and 7, the first two years are often considered and referred to as clinically presymptomatic.

Estrogen-related receptor (ERR) alpha is an orphan nuclear receptor highly expressed in the kidneys. ERRalpha is implicated in renal sodium and potassium homeostasis and blood pressure regulation. We used microarray analysis to identify differentially expressed genes in ERR alpha knockout mice kidneys versus wild-type. The results provide insight on the roles of ERRalpha in the kidney.

Description
We used RNA-seq to define the gene expression profiles of intestinal stem cells (ISCs) expanded in Matrigel, degradable poly(ethylene) glycol (PEG) and non-degradable PEG matrices. Comparison of mRNA profiles between ISCs grown in Matrigel and non-degradable PEG show no major differences in expression of gene related to stemness, proliferation and signaling via the Wnt and Notch pathways. These results also show that ISC cultured in degradable PEG matrices upregulate stress- and inflammation-related genes compared with cells expanded in non-degradable PEG matrices. Overall design: mRNA profiles of ISCs cultured in the three types of matrices for 4 days were generated in triplicate
