Project description:Primary objectives: The primary objective is to investigate circulating tumor DNA (ctDNA) via deep sequencing for mutation detection and by whole genome sequencing for copy number analyses before start (baseline) with regorafenib and at defined time points during administration of regorafenib for treatment efficacy in colorectal cancer patients in terms of overall survival (OS).

Project description:Omics approaches are broadly used to explore endocrine and toxicity-related pathways and functions. Nevertheless, there is still a significant gap in knowledge in terms of understanding the endocrine system and its numerous connections and intricate feedback loops, especially in non-model organisms. The fathead minnow (Pimephales promelas) is a widely used small fish model for aquatic toxicology and regulatory testing, particularly in North America. A draft genome has been published but the amount of available genomic or transcriptomic information is still far behind that of other more broadly studied species, such as the zebrafish. Here, we surveyed the tissue-specific proteome and transcriptome profiles in adult male fathead minnow. To do so, we generated a draft transcriptome using short and long sequencing reads. We also performed RNA sequencing and proteomics analysis on the telencephalon, hypothalamus, liver, and gut of male fish. The main purpose of this analysis was to generate tissue-specific omics data in order to support future aquatic ecotoxicogenomic and endocrine-related studies as well as to improve our understanding of the fathead minnow as an ecological model.

Project description:Drosophila X chromosomes are subject to dosage compensation in males and are known to have a specialized chromatin structure in the male soma. We are interested in how specific chromatin structure change contributes to X chromosome hyperactivity and dosage compensation. We have conducted a global analysis of localize two dosage compensation complex dependent histone marks H4AcK16 and H3PS10 and one dosage compensation complex independent histone mark H3diMeK4 in the genome, especially on X chromosome by ChIP-chip approach in both male and female adult flies. We also probed general genomewide chromatin structure by deep DNA sequencing of sheared ChIP input DNA from male and female adult flies.
