Description
The proper balance of excitatory and inhibitory neurons is crucial to normal processing of somatosensory information in the dorsal spinal cord. Two neural basic helix-loop-helix transcription factors, Ascl1 and Ptf1a, are essential for generating the correct number and sub-type of neurons in multiple regions of the nervous system. Â In the dorsal spinal cord, Ascl1 and Ptf1a have contrasting functions in specifying inhibitory versus excitatory neurons. To understand how Ascl1 and Ptf1a function in these processes, we identified their direct transcriptional targets genome-wide in the embryonic mouse neural tube using ChIP-Seq and RNA-Seq. We show that Ascl1 and Ptf1a regulate the specification of excitatory and inhibitory neurons in the dorsal spinal cord through direct regulation of distinct homeodomain transcription factors known for their function in neuronal sub-type specification. Besides their roles in regulating these homeodomain factors, Ascl1 and Ptf1a each function differently during neuronal development with Ascl1 directly regulating genes with roles in several steps of the neurogenic program including, Notch signaling, neuronal differentiation, axon guidance, and synapse formation. In contrast, Ptf1a directly regulates genes encoding components of the neurotransmitter machinery in inhibitory neurons, and other later aspects of neural development distinct from those regulated by Ascl1. Moreover, Ptf1a represses the excitatory neuronal fate by directly repressing several targets of Ascl1. Examination of the Ascl1 and Ptf1a bound sequences shows they are enriched for a common E-Box with a GC core and with additional motifs used by Sox, Rfx, Pou, and Homeodomain factors. Ptf1a bound sequences are uniquely enriched in an E-Box with a GA/TC core and in the binding motif for its co-factor Rbpj, providing two keys to specificity of Ptf1a binding. The direct transcriptional targets identified for Ascl1 and Ptf1a provide a molecular understanding for how they function in neuronal development, particularly as key regulators of homeodomain transcription factors required for neuronal sub-type specification. Overall design: Examination of gene expression in Ascl1 and Ptf1a lineage cells in the developing neural tube.

Description
A chemopreventive effect of aspirin (ASA) on lung cancer risk is supported by epidemiologic and preclinical studies. We conducted a randomized, double-blind, placebo controlled study in current heavy smokers to compare modulating effects of intermittent versus continuous low dose ASA on gene signatures of smoking and lung cancer from nasal brushings. Fifty-four participants were randomized to intermittent ASA (ASA 81 mg daily for one week alternating with placebo daily for one week) or continuous ASA (81 mg daily) for 12 weeks. The primary endpoint was modulation of a smoking gene signature in nasal brushings. Other [JB1] endpoints included modulation of nasal and bronchial gene signatures for smoking, lung cancer and chronic obstructive pulmonary disease (COPD) and changes in cyclooxygenase (COX)- and 5-lipoxygenase (LOX)-mediated arachidonic acid (ARA) metabolism.

Description
To understand the functional relationship between brain dendritic cells (brain DCs) and other myeloid cells, we compared the gene expression profile of m/chDCs to that of bone marrow monocytes, brain microglia and classical spleen CD8+ and CD8- DCs. In order to obtain enough brain DCs for mRNA extraction, we expanded brain DCs with in vivo Flt3L treatment before purification.

Description
Cutaneous malignant melanoma is among the most deadly human cancers, broadly resistant to most clinical therapies. A majority of patients with BRAFV600E melanomas respond well to inhibitors such as vemurafenib, but all ultimately relapse. Moreover, there are no viable treatment options available for other non-BRAF melanoma subtypes in the clinic. A key to improving treatment options lies in a better understanding of mechanisms underlying melanoma progression, which are complex and heterogeneous. In this study we perform gene expression profilling of highly and poorly malignant melanocytic tumors from genetically engineered mouse models to discover important drivers of cancer progression.

Description
Classical dendritic cells (cDCs) process and present antigens to T cells. Under steady-state conditions, antigen presentation by cDCs induces tolerance. In contrast, during infection or inflammation, cDCs become activated, express higher levels of cell surface MHC molecules, and induce strong adaptive immune responses. We recently identified a cDC-restricted zinc finger transcription factor, zDC, that is not expressed by other immune cell populations, including pDCs, monocytes, or macrophages. Here we define the zDC consensus DNA binding motif and the genes regulated by zDC using chromatin immunoprecipitation and deep sequencing. By deleting zDC from the mouse genome, we show that zDC is primarily a negative regulator of cDC gene expression. zDC deficiency alters the cDC subset composition in the spleen in favor of CD8+ DCs, upregulates activation pathways in steady state cDCs including elevated MHC II expression, and enhances cDC production of VEGF leading to increased vascularization of skin-draining lymph nodes. Consistent with these observations, zDC protein expression is rapidly downregulated after TLR ligation. Thus, zDC is a TLR-responsive cDC-specific transcriptional repressor that is in part responsible for preventing cDC maturation in the steady state.
