Description
We obtained full transcriptome data from single cortical neurons after whole-cell patch-clamp recording (termed “Patch-seq”). By applying “Patch-seq” to cortical neurons, we reveal a close link between biophysical membrane properties and genes coding for neurotransmitter receptors and channels, including well-established and hitherto undescribed subtypes. Overall design: RNA sequencing was performed on a total of 83 individual cells
Publication Title
Integration of electrophysiological recordings with single-cell RNA-seq data identifies neuronal subtypes.

Affymetrix Human Transcriptome Array 2.0 (hta20)
Description
Intrahepatic Cholangiocarcinoma (iCCA) is a deadly disease with rising incidence and few treatment options. Recently, aberrant Notch signaling was reported in iCCA carcinogenesis. Specifically, altered expression and/or activation of the receptors Notch1/2 suggests a role for Notch pathway overactivation during iCCA formation and progression. In this study, we examined the effects of Notch inhibition by γ-secretase inhibitor, LY3039478 in human iCCA cell lines and in an excellent patient derived-xenograft (PDX) model. Expression of several Notch pathway components, including NICD, Hes1, and DLL4, were reduced after GSI treatment. Moreover, LY3039478 inhibits cell migration and invasion while in GSI-treated mice, tumor growth was delayed compared to vehicle and chemotherapy. These results support the notion that Notch inhibition by GSI may reduce in vivo tumorigenesis. In addition, GSI reduces in PDX model VEGFA and MMP13 involved in capillary tube formation and tumor progression. Here, we therefore show a link between the efficacy of Notch inhibition and the tumor microenvironment through LY3039478 that slows tumor progression compared to control mice blocking angiogenesis via MMP13 downregulation.

- Affymetrix C. elegans Genome Array (celegans)
Description
We used microarray analysis to further our understanding of the mode of action of the well know caloric restriction mimetic rapamycin and the compound Allantoin first studied in the context of aging in this study. His work helps build on our understanding of potential caloric restriction mimetics predicted from our bioinformatic aproach of quering the Connectivity Map, a database of drug-induced gene expression profiles, using the transcriptional profile of CR to identify drugs that induce a similar or opposite gene expression profile.

Description
The unfolded protein response (UPR) is activated in response to hypoxia-induced stress such as in the tumor microenvironment. This study examined the role of CREB3L1 (cAMP-responsive element-binding protein 3-like protein 1), a member of the UPR, in breast cancer development and metastasis. Initial experiments identified the loss of CREB3L1 expression in metastatic breast cancer cell lines compared to low- or non-metastatic cell lines. When metastatic cells were transfected with CREB3L1 they demonstrated reduced invasion and migration in vitro, as well as a significantly decreased ability to survive under non-adherent or hypoxic conditions. Interestingly, in an in vivo rat mammary tumor model, CREB3L1 expressing cells not only failed to form metastases compared to CREB3L1 null cells but regression of the primary tumors was seen in 70% of the animals as a result of impaired angiogenesis. Microarray and ChIP on Chip analyses identified changes in the expression of many genes involved in cancer development and metastasis, including a decrease in those involved in angiogenesis. These data suggest that CREB3L1 plays an important role in suppressing tumorgenesis and loss of expression is required for the development of a metastatic phenotype.

Description
Platelets have multiple roles in cancer cell metastasis. In this work we employed exon microarray technology to address platelet gene expression in metastatic non small cell lung cancer versus controls without cancer. We found that 197 of the 200 genes with the most significantly altered expression levels had their expression levels downregulated.

Description
Sertoli cells (SCs), the only somatic cells within seminiferous tubules, associate intimately with developing germ cells. They not only provide physical and nutritional support but also secrete factors essential to the complex developmental processes of germ cell proliferation and differentiation. The SC transcriptome must therefore adapt rapidly during the different stages of spermatogenesis. We report comprehensive genome-wide expression profiles of pure populations of SCs isolated at 5 distinct stages of the first wave of mouse spermatogenesis, using RNA sequencing technology. We were able to reconstruct about 13 901 high-confidence, nonredundant coding and noncoding transcripts, characterized by complex alternative splicing patterns with more than 45% comprising novel isoforms of known genes. Interestingly, roughly one-fifth (2939) of these genes exhibited a dynamic expression profile reflecting the evolving role of SCs during the progression of spermatogenesis, with stage-specific expression of genes involved in biological processes such as cell cycle regulation, metabolism and energy production, retinoic acid synthesis, and blood-testis barrier biogenesis. Finally, regulatory network analysis identified the transcription factors endothelial PAS domain-containing protein 1 (EPAS1/Hif2a), aryl hydrocarbon receptor nuclear translocator (ARNT/Hif1ß), and signal transducer and activator of transcription 1 (STAT1) as potential master regulators driving the SC transcriptional program. Our results highlight the plastic transcriptional landscape of SCs during the progression of spermatogenesis and provide valuable resources to better understand SC function and spermatogenesis and its related disorders, such as male infertility.
