A multicenter translational biomarker phase II trial of regorafenib in patients with non-resectable pretreated colorectal cancer.

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).

Muscle Transcriptomic Investigation of Late Fetal Development Identifies Candidate Genes for Key Roles in Piglet Maturity

Project description:To further knowledge of piglet maturity, we have developed a microarray analysis to describe biological processes and to find candidate genes for key roles in piglet maturity. The objective was to identify which genes and biological processes are specifically involved in the difference between two extreme breeds: Large White (LW) and Meishan (MS). The LW breed is a selected breed known to show an increased rate of mortality at birth, while the MS breed presents more robust piglets at birth. MS and LW sows were inseminated with mixed semen (LW and MS) hence each litter was composed of pure fetuses (LW or MS) and crossed fetuses (LWMS from MS sows and MSLW from LW sows).

MicroRNA transcriptome profiling in ovarian tissues of pigs with extreme phenotypes for reproductive efficiency during the luteal and follicular phases of the estrous cycle

Project description:Purpose:The goal of this study was to enrich understanding of the reproductive difference Methods: Multiparous Canadian Large White cyclic sows were divided into two parts: high (H; total number of piglets born > 15.73) and low (L; total number of piglets born < 11.11) fecundity. Eight sows with similar parity from each part were chosen (n=16). Ovarian tissues were obtained on the 14 day (day 1 = first day of estrus) after estrus as in the luteal phase (L) and 20 day of the estrous cycle as in the follicular phase (F). Transcriptome profiling of ovarian tissues were generated by deep sequencing, in quadruplicate, using Illumina HiSeq X10 instrument. Results: Using an optimized data analysis workflow, we obtained the differentially expressed miRNAs between the high and low fecundity, with a fold change ≥1.5 and p value < 0.05. These results provide further insight into fecundity in pigs. Conclusions: Our study represents the first detailed analysis of ovary transcriptome. It will be significantly helpful to display a novel regulatory mechanism for further investigation of prolificacy in pigs.

Defining Cellular Diversity at the Swine Maternal-Fetal Interface Using Spatial Transcriptomics and Organoids

Project description:n this study we had two primary aims: 1.) spatially define the transcriptional signatures of porcine maternal-fetal interface and 2.) develop and validate an organoid model which better recapitulated the porcine placenta. Using mid-gestation maternal-fetal interfaces of commercial landrace/large white composite gilts we performed spatial transcriptomics (n=4 interfaces) using Visium v1 spatial transcriptomics. We then went on to isolate trophoblast organoids from fresh-term placentas from crossbred sows consisting</p><p>655 of Yorkshire, Large White, and Landrace breeds. We then characterized the transcriptional profile of these organoids using bulk RNA-seq from 3 seperate lines using a standard Illumina library preparation. To characterize these organoids we performed single cell RNA-sequencing on 3 separate lines of swine trophoblast organoids using a standard 10x Genomics Single Cell 3' Gene Expression platform. All reads/samples were mapped to Sus scrofa v11.1.

aSyn polyA-RNAseq in PD and unaffected cortical brain samples

Project description:We sought to more precisely characterize the different alpha-synuclein (aSyn) 3’UTR mRNA species in normal and PD human brain. High-throughput, whole-transcriptome sequencing of the 3’UTR ends of polyadenylated mRNA transcripts (termed pA-RNAseq; see Methods) was performed on a cohort of 17 unaffected and 17 PD cerebral cortical tissue samples. This revealed 5 aSyn 3’UTR isoforms, with lengths of 290, 480, 560, 1070 and 2520 nt. Of these, the 560 nt and 2520 nt forms were predominant. The existence and relative preponderance of these species was further confirmed by Northern Blot. We next hypothesized, that aSyn 3’UTR selection might be altered in PD. Comparison of pA-RNAseq profiles from PD and unaffected cerebral cortex samples revealed an increase in the preponderance of the long 3’UTR species (>560 nt) relative to shorter species (<560 nt). Such a relative increase in aSynL was confirmed by Quantitative real-time RT-PCR (rt-qPCR) and appeared specific for PD, as the increase was also observed by comparison to RNA from amyotrophic lateral sclerosis patient samples. We note that the modified aSyn 3’UTR selection associated with PD patient tissue was detected in cerebral cortex tissue, which typically harbors pathological evidence of the disease process without frank cell loss; thus, this phenotype is unlikely to be a secondary consequence of neurodegeneration.
