Project description:For a number of clinical and biological reasons, the accurate classification of non-small cell lung carcinoma (NSCLC) into adenocarcinoma (ADC) and squamous cell carcinoma (SCC) is essential. DNA-based tests, which are not currently used, are more robust when applied to formalin-fixed paraffin-embedded tissues. To develop a molecular-based classification of NSCLC based on genome wide copy number variations (CNVs), the corresponding TCGA, SPORE and CANARY patient datasets were used as training and independent validation data. The signature genes were selected by advanced supervised classification algorithms and restricted to known important oncogenes/tumor suppressors, resulting in a final 27-gene signature that was able to classify ADC from SCC with 0.85-0.87 accuracies of SPORE validation sets and 0.96-0.98 accuracy of CANARY validation sets. Even by using the top 7 genes in this signature, the accuracies of the validation sets were still as high as 0.80 and 0.97, respectively. These signature genes also classified adenocarcinoma and squamous cell carcinomas from the non-malignant lung samples with accuracies of 91-97%.
Project description:In the present study, we performed HITS-CLIP analysis for FUS using mouse brain to extensively characterize tits RNA-binding sites and functional roles in RNA metabolisms. We identified preferential binding of FUS to stem-and-loop structures but without any discernible consensus motifs. FUS was preferentially bound to introns and 3' untranslated regions, but the exon/intron boundaries were mostly devoid of FUS-tags. Analysis of position-dependence of FUS-binding sites in regulating inclusion and skipping of exons disclosed that FUS is bound broadly around the alternatively spliced exons. Among them, however, noticeable CLIP-tags were observed in the downstream introns. We also noticed that FUS occasionally binds to the antisense strands in the promoter regions. Global analysis of CLIP-tags and expression profiles revealed that binding of FUS to the promoter antisense regions downgregulates transcription of the sense strand.

Abstract:
Clinical investigations prove that blue light irradiation
reduces the severity of psoriasis vulgaris. Nevertheless, the
mechanisms involved in the management of this condition remain
poorly defined. Despite the encouraging results of the clinical
studies, no clear guidelines are specified in the literature
for the irradiation scheme regime of blue light-based therapy
for psoriasis. We investigated the underlying mechanism of blue
light irradiation of psoriatic skin, and tested the hypothesis
that regulation of proliferation is a key process. We
implemented a mechanistic model of cellular epidermal dynamics
to analyze whether a temporary decrease of keratinocytes
hyper-proliferation can explain the outcome of phototherapy
with blue light. Our results suggest that the main effect of
blue light on keratinocytes impacts the proliferative cells.
They show that the decrease in the keratinocytes proliferative
capacity is sufficient to induce a transient decrease in the
severity of psoriasis. To study the impact of the therapeutic
regime on the efficacy of psoriasis treatment, we performed
simulations for different combinations of the treatment
parameters, i.e., length of treatment, fluence (also referred
to as dose), and intensity. These simulations indicate that
high efficacy is achieved by regimes with long duration and
high fluence levels, regardless of the chosen intensity. Our
modeling approach constitutes a framework for testing diverse
hypotheses on the underlying mechanism of blue light-based
phototherapy, and for designing effective strategies for the
treatment of psoriasis.

Project description:Based on its phylogenetic relationship to monitor lizards (Varanidae), Gila monsters (Heloderma spp.), and the earless monitor Lanthanotus borneesis, the Chinese crocodile lizard, Shinisaurus crocodilurus, has been assigned to the Toxicofera clade, which comprises venomous reptiles. However, no data about composition and biological activities of its oral secretion have been reported. In the present study, a proteomic analysis of the mandibular gland of S. crocodilurus and, for comparison, of the herbivorous Solomon Island skink Corucia zebrata, was performed. Scanning electron microscopy (SEM) of the teeth from S. crocodilurus revealed a sharp ridge on the anterior surface, but no grooves, whereas those of C. zebrata possess a flattened crown with a pointed cusp. Proteomic analysis of their gland extracts provided no evidence of venom-derived peptides or proteins, strongly supporting the non-venomous character of these lizards.
