Description
Cutaneous squamous cell carcinoma (cuSCC) comprises 15-20% of all skin cancers, accounting for over 700,000 cases in the U.S. annually. Most cuSCC arise in association with a distinct precancerous lesion, the actinic keratosis (AK). In order to identify potential targets for molecularly targeted chemoprevention, we performed integrated cross-species genomic analysis of cuSCC development through the preneoplastic AK stage using matched human samples and a solar UV-driven Hairless mouse model. We identified the major transcriptional drivers of this sequence showing that the key genomic changes in cuSCC development occur in the normal skin to AK transition. Our data validate the use of this UV-driven mouse cuSCC model for cross-species analysis and demonstrate that cuSCC bears deep molecular similarities to multiple carcinogen-driven SCCs from diverse sites, suggesting that cuSCC may serve as an effective, accessible model for multiple SCC types and that common treatment and prevention strategies may be feasible. Overall design: We sought to identify important genetic events that drive squamous cell carcinoma development through combined analysis of next generation sequencing of matched patient samples with a UV-driven mouse model to identify key pathways.

Description
The goal of this work was to examine if reserveratrol or rosiglitazone treatment could improve the metabolic status of obese male ZDF rats after 6 weeks. Gene expression was analyzed in several key metabolic tissues, including liver, various white adipose tissue depots, red tibalus muscle, and peripheral blood mononuclear cells.

Description
Stearoyl-CoA desaturase (SCD) is the rate-limiting enzyme catalyzing the conversion of saturated fatty acids palmitate and stearate to monounsaturated fatty acids palmitoleate and oleate. During adipocyte differentiation, SCD expression increases concomitantly with several transcription factors and lipogenic genes.

Description
Human pluripotent stem cells (hPSCs) have been reported in naïve and primed states. However, the ability of human PSCs to generate mature cell types is the only imperative property for translational utility. Here, we reveal that the naïve state enhances self-renewal capacity while restricting lineage differentiation in vitro to neural default fate. Gene expression analyses indicate expression of multiple lineage associated transcripts in naïve hPSCs and thus failed to predict biased functional differentiation. Naïve hPSCs can be converted to primed allowing recovery of multilineage differentiation over long serial passage or immediately through suppression of OCT4 but not NANOG. To this end, we identified chemical inhibitors of OCT4 expression that acutely restore naïve hPSC differentiation. Our study identifies unique cell fate features and critical restrictions in human pluripotent states, and provides an approach to overcome these barriers that harness both efficient naïve hPSC growth whilst maintaining in vitro differentiation capacities essential for hPSC applications. Overall design: hPSC lines were transduced with shRNA lentiviruses in order to assess the effects of reducing NANOG and OCT4 gene expression on differention in the naïve state. shRNA expressing cells were sorted and then total RNA was extracted in order to perform transcriptome profiling by RNA-seq. Each experimental condition involves 2 technical replicates of 2 biological replicates (2 tech X 2 biol = 4 reads).

Description
Direct cell fate conversion allows the generation of somatic cells that are otherwise difficult to obtain directly from patients. The clinical applicability of this approach depends on obtaining an initial source of somatic cells from adult patients that is easy to harvest, store, and manipulate for reprogramming. Here we have generated induced neural progenitor cells (iNPCs) from neonatal as well as peripheral blood from human adults using single factor OCT4 based reprogramming. Unlike fibroblasts that share molecular hallmarks of neural crest, direct OCT4 reprogramming of human blood could be facilitated by SMAD+GSK-3 inhibition to overcome restrictions on neural fate conversion. Blood derived (BD)-iNPCs functionally differentiate in vivo, and respond to guided differentiation in vitro to produce both glia (astrocytes and oligodendrocytes) and multiple neuronal subtypes including dopamine releasing DA neurons (CNS related) and nociceptive neurons (PNS). Furthermore, BD nociceptive neurons phenocopy chemotherapy induced neurotoxicity in a system suitable for high throughput drug screening. Our findings provide an easily accessible approach to generate human NPCs that harbor extensive developmental potential, enabling the study of clinically relevant neural diseases directly from patient cohorts.
