Description
We sorted Eomes-negative NK cells (CD3- CD56+ CXCR6- CD16-) and Eomes-positive NK cells (CD3- CD56+ CXCR6+) from total leukocytes isolated from the perfusion fluid of five healthy human livers destined for transplantation. Total RNA was extracted from sorted cells, cDNA generated and RNASeq performed. Overall design: Examination of mRNA levels in paired Eomes-negative/Eomes-positive NK cells from the same donor.

Description
Previous in vitro studies in our lab have shown that CD24, a cell surface receptor, actively regulates lipid accumulation in adipocytes. But how CD24 regulates this process remains unknown. In order to answer this question, we initially tested to determine if CD24 regulates lipid accumulation by regulating glucose uptake in adipocytes in vitro. We observed that instead, CD24 caused the dysregulation of the expression of 134 genes as determined by DNA microarray analysis. We then validated the expression of select four genes, when CD24 is knocked down during the different stages of adipogenesis in 3T3-L1 pre-adipocytes in vitro. To further confirm the role of these genes, we then determined the expression patterns of these four genes in primary cells undergoing adipogenesis that were isolated from the epididymal and inguinal white adipose tissue depots of CD24 knockout mice. Surprisingly, we found that these genes were dysregulated in the inguinal but not the epididymal depot in vitro. Overall, the data presented here suggests that CD24 is necessary for select gene expression, but not glucose uptake, during adipogenesis in vitro.

Description
The purpose of this study was to analyze the genomic signatures and profiles of skin from ichthyosis (various subtypes) vs. healthy patients. The analysis strategy was to study differentially expressed genes common to the ichthyosis shared phenotype, as well as individual ichthyosis subtypes, and compare and contrast to the genomic profiles of atopic dermatitis and psoriasis.

Description
Background: Atopic dermatitis (AD) predominantly affects young children, but our understanding of AD pathogenesis is based on skin and blood samples from longstanding adult AD. Genomic biopsy profiling from early pediatric AD showed significant Th2 and Th17/Th22-skewing, without the characteristic adult Th1 up-regulation. Since obtaining pediatric biopsies is difficult, blood gene expression profiling may provide a surrogate for the pediatric skin signature.

Description
Background. Androgen receptor splice variant-7 (AR-V7) is a truncated form of the androgen receptor protein which lacks the ligand-binding domain, the target of enzalutamide and abiraterone, but remains constitutively active as a transcription factor. We hypothesized that detection of AR-V7 in circulating tumor cells (CTCs) from men with advanced prostate cancer would be associated with resistance to enzalutamide and abiraterone. Methods. We used quantitative reverse-transcription polymerase-chain-reaction (qRT-PCR) to interrogate CTCs for the presence or absence of AR-V7 from prospectively enrolled patients with metastatic castration-resistant prostate cancer initiating treatment with either enzalutamide or abiraterone. We examined associations between AR-V7 status and PSA response rates, PSA-progression-free-survival (PSA-PFS), clinical/radiographic-progression-free-survival (PFS), and overall survival (OS). Multivariable Cox regression analyses were performed to determine the independent effect of AR-V7 status on clinical outcomes. Results. Thirty-one enzalutamide-treated patients and thirty-one abiraterone-treated patients were enrolled, of which 38.7% and 19.4% had detectable AR-V7 from CTCs, respectively. Among men receiving enzalutamide, AR-V7–positive patients had inferior PSA response rates (0% vs 52.6%, P=0.004), PSA-PFS (median: 1.4 vs 6.0 months, P<0.001), PFS (median: 2.1 vs 6.1 months, P<0.001), and OS (median: 5.5 months vs not reached, P=0.002) compared to AR-V7–negative patients. Similarly, among men receiving abiraterone, AR-V7–positive patients had inferior PSA response rates (0% vs 68.0%, P=0.004), PSA-PFS (median: 1.3 months vs not reached, P<0.001), PFS (median: 2.3 months vs not reached, P<0.001), and OS (median: 10.6 months vs not reached, P=0.006). The negative prognostic impact of AR-V7 was maintained after adjusting for full-length-AR expression. Conclusions. Detection of AR-V7 in CTCs from patients with castration-resistant prostate cancer is associated with resistance to enzalutamide and abiraterone. Overall design: A total of four metastatic castration-resistant prostate tumor samples from four patients were subjected to RNA-seq. Two samples were positive for androgen receptor splice variant 7 and the other two were negative for this variant.

Description
In this study we investigated the mechanisms involved in memory T-cell mediated protection using mice vaccinated with the intracellular bacterium Listeria monocytogenes. Our working hypothesis was that rapid activation of cells of the innate immune system, in particular inflammatory Ly6C+ monocytes, were essential in effective protection, in a memory T cell-dependent manner. Thus we generated a comprehensive comparison of the genetic program of activated Ly6C+ monocytes during a primary or a secondary infection with Listeria monocytogenes, at 8 hours post challenge infection.
