TL;DR: In this article, it was shown that 3' cleavage of pre-mRNA in eukaryotes is, in many ways, the phenotypic equivalent of transcription termi-nation.

TL;DR: It is shown that pro-B cells lacking Pax5 are also incapable of in vitro B-cell differentiation unless Pax5 expression is restored by retroviral transduction, and Pax5 plays an essential role in B-lineage commitment by suppressing alternative lineage choices.
Abstract: The Pax5 gene encoding the B-cell-specific activator protein (BSAP) is expressed within the haematopoietic system exclusively in the B-lymphoid lineage, where it is required in vivo for progression beyond the pro-B-cell stage. However, Pax5 is not essential for in vitro propagation of pro-B cells in the presence of interleukin-7 and stromal cells. Here we show that pro-B cells lacking Pax5 are also incapable of in vitro B-cell differentiation unless Pax5 expression is restored by retroviral transduction. Pax5-/- pro-B cells are not restricted in their lineage fate, as stimulation with appropriate cytokines induces them to differentiate into functional macrophages, osteoclasts, dendritic cells, granulocytes and natural killer cells. As expected for a clonogenic haematopoietic progenitor with lymphomyeloid developmental potential, the Pax5-/- pro-B cell expresses genes of different lineage-affiliated programmes, and restoration of Pax5 activity represses this lineage-promiscuous transcription. Pax5 therefore plays an essential role in B-lineage commitment by suppressing alternative lineage choices.

TL;DR: Interestingly, the CHILP differentiated into ILC2 and ILC3 lineages, but not into conventional natural killer cells that have been considered an ILC1 subset, presenting evidence for a new ILC lineage that protects barrier surfaces against intracellular infections.
909 citations
TL;DR: A key role for Pax5 is defined in early B lymphopoiesis and midbrain patterning and all mutants failed to produce small pre-B, B, and plasma cells owing to a complete arrest of B cell development at an early precursor stage.
810 citations
TL;DR: It is demonstrated that GATA-3 is essential for ILC2 fate decisions and similarities between the transcriptional programs controlling ILC and T helper cell fates are revealed.

TL;DR: The philosophy and design of the limma package is reviewed, summarizing both new and historical features, with an emphasis on recent enhancements and features that have not been previously described.
Abstract: limma is an R/Bioconductor software package that provides an integrated solution for analysing data from gene expression experiments. It contains rich features for handling complex experimental designs and for information borrowing to overcome the problem of small sample sizes. Over the past decade, limma has been a popular choice for gene discovery through differential expression analyses of microarray and high-throughput PCR data. The package contains particularly strong facilities for reading, normalizing and exploring such data. Recently, the capabilities of limma have been significantly expanded in two important directions. First, the package can now perform both differential expression and differential splicing analyses of RNA sequencing (RNA-seq) data. All the downstream analysis tools previously restricted to microarray data are now available for RNA-seq as well. These capabilities allow users to analyse both RNA-seq and microarray data with very similar pipelines. Second, the package is now able to go past the traditional gene-wise expression analyses in a variety of ways, analysing expression profiles in terms of co-regulated sets of genes or in terms of higher-order expression signatures. This provides enhanced possibilities for biological interpretation of gene expression differences. This article reviews the philosophy and design of the limma package, summarizing both new and historical features, with an emphasis on recent enhancements and features that have not been previously described.

TL;DR: Processes similar to the EMTs associated with embryo implantation, embryogenesis, and organ development are appropriated and subverted by chronically inflamed tissues and neoplasias and the identification of the signaling pathways that lead to activation of EMT programs during these disease processes is providing new insights into the plasticity of cellular phenotypes.
Abstract: The origins of the mesenchymal cells participating in tissue repair and pathological processes, notably tissue fibrosis, tumor invasiveness, and metastasis, are poorly understood. However, emerging evidence suggests that epithelial-mesenchymal transitions (EMTs) represent one important source of these cells. As we discuss here, processes similar to the EMTs associated with embryo implantation, embryogenesis, and organ development are appropriated and subverted by chronically inflamed tissues and neoplasias. The identification of the signaling pathways that lead to activation of EMT programs during these disease processes is providing new insights into the plasticity of cellular phenotypes and possible therapeutic interventions.

TL;DR: Epithelial–mesenchymal transition provides a new basis for understanding the progression of carcinoma towards dedifferentiated and more malignant states.
Abstract: Without epithelial–mesenchymal transitions, in which polarized epithelial cells are converted into motile cells, multicellular organisms would be incapable of getting past the blastula stage of embryonic development. However, this important developmental programme has a more sinister role in tumour progression. Epithelial–mesenchymal transition provides a new basis for understanding the progression of carcinoma towards dedifferentiated and more malignant states.

TL;DR: It is proposed that the AU sequences are the recognition signal for an mRNA processing pathway which specifically degrades the mRNAs for certain lymphokines, cytokines, and proto-oncogenes.

TL;DR: It is argued that NF-κB functions more generally as a central regulator of stress responses and pairing stress responsiveness and anti-apoptotic pathways through the use of a common transcription factor may result in increased cell survival following stress insults.
Abstract: Sixteen years have passed since the description of the nuclear factor-кB (NF-кB) as a regulator of к light-chain gene expression in murine B lymphocytes (Sen & Baltimore, 1986a) During that time, over 4,000 publications have appeared, characterizing the family of Rel/NF-кB transcription factors involved in the control of a large number of normal and pathological cellular processes The physiological functions of NF-кB proteins include immunological and inflammatory responses, developmental processes, cellular growth and modulating effects on apoptosis In addition, these factors are activated in a number of diseases, including cancer, arthritis, acute and chronic inflammatory states, asthma, as well as neurodegenerative and heart diseases
