Description
Development of spider veins is caused by the remodeling of veins located in the upper dermis and promoted by risk factors such as obesity or pregnancy that chronically increase venous pressure. We have repeatedly shown that the pressure-induced increase in biomechanical wall stress is sufficient to evoke the formation of enlarged corkscrew-like superficial veins in mice. Subsequent experimental approaches revealed that interference with endothelial- and/or smooth muscle cell activation counteracts this remodeling process. Here, we investigate whether the herbal agent glycyrrhetinic acid (GA) is a suitable candidate for that purpose given its anti-proliferative as well as anti-oxidative properties.

Description
Although it is increasingly accepted that some paternal environmental conditions can influence phenotypes in future generations, it generally remains unclear whether the phenotypes induced in offspring represent specific responses to particular aspects of the paternal exposure history, or whether they represent a more generic response to paternal “quality of life”. To establish a paternal effect model based on a known ligand-receptor interaction and thereby enable pharmacological interrogation of the specificity of the offspring response, we explored the effects of paternal nicotine administration on offspring phenotype in mouse. We show that chronic paternal exposure to nicotine prior to reproduction induced a broad protective response to multiple xenobiotics in the next generation. This effect manifested as increased survival following an injection of toxic levels of either nicotine or of cocaine, was specific to male offspring, and was only observed after offspring were first acclimated to sublethal doses of nicotine or cocaine. Mechanistically, the reprogrammed state was characterized by enhanced clearance of nicotine in drug-acclimated animals, accompanied by hepatic upregulation of genes involved in xenobiotic metabolism. Surprisingly, this protective effect could also be induced by paternal exposure to a nicotinic receptor antagonist as well as to nicotine, suggesting that paternal xenobiotic exposure, rather than nicotinic receptor signaling, is likely to be responsible for programming of offspring drug resistance. Taken together, our data show that paternal drug exposure can induce a protective phenotype in offspring by enhancing metabolic tolerance to xenobiotics in the environment. Overall design: Hepatocytes were isolated from 8 week-old male F1 animals from control (TA) and nicotine-exposed (NIC) fathers, and allowed to adhere to the bottom of the well for three hours. Nonadherent cells were then removed, and fresh culture medium was then added. Cells were harvested at different time points in Trizol, and total RNA was extracted. Strand specific libraries were prepared from all samples, and sequenced on Illumina NextSeq500.

Description
The ability of dendritic cells (DCs) to activate immunity is linked to their maturation status. In prior studies we have shown that selective antibody-mediated blockade of inhibitory FcgRIIB receptor on human DCs in the presence of activating immunoglobulin (Ig) ligands leads to DC maturation and enhanced immunity to antibody-coated tumor cells. Here we show that Fcg receptor (FcgR) mediated activation of human monocytes and monocyte-derived DCs is associated with a distinct gene expression pattern, including several inflammation associated chemokines as well as type 1 interferon (IFN) response genes including the activation of signal transducer and activator of transcription 1 (STAT1).

Description
Oral squamous cell carcinoma (OSCC) is a prevalent form of cancer that develops from the epithelium of the oral cavity. OSCC is on the rise worldwide, and death rates associated with the disease are particularly high. Despite progress in understanding of the mutational and expression landscape associated with OSCC, advances in deciphering these alterations for the development of therapeutic strategies have been limited. Further insight into the molecular cues that contribute to OSCC is therefore required. Here we show that the transcriptional regulators YAP (YAP1) and TAZ (WWTR1), which are key effectors of the Hippo pathway, drive pro-tumorigenic signals in OSCC. Regions of pre-malignant oral tissues exhibit aberrant nuclear YAP accumulation, suggesting that dysregulated YAP activity contributes to the onset of OSCC. Supporting this premise, we determined that nuclear YAP and TAZ activity drives OSCC cell proliferation, survival, and migration in vitro, and is required for OSCC tumor growth and metastasis in vivo. Global gene expression profiles associated with YAP and TAZ knockdown revealed changes in the control of gene expression implicated in pro-tumorigenic signaling, including those required for cell cycle progression and survival. Notably, the transcriptional signature regulated by YAP and TAZ significantly correlates with gene expression changes occurring in human OSCCs identified by The Cancer Genome Atlas (TCGA), emphasizing a central role for YAP and TAZ in OSCC biology.

We investigated the molecular mechanisms for osteolytic bone metastasis by selecting human lung cancer cell line subpopulations with elevated metastatic activity and validating genes that are overexpressed in these cells. A bone-seeking squamous lung cancer cell line (HARA-B4) was established by sequentially injecting parental HARA cells into the left ventricle of male 5-week-old nude mice 4 times.

Description
Pulmonary hypertension is a frequent consequence of left heart disease and congestive heart failure (CHF) and causes extensive lung vascular remodelling which leads to right ventricular failure. Functional genomics underlying this structural remodelling are unknown but present potential targets for novel therapeutic strategies. We used microarrays to detail the gene expression underlying vascular remodeling in the pathogenesis of pulmonary hypertension and identified distinct classes of up-regulated genes during this process.
