Project description:Expression profiles of porcine muscle Semimembranosus were studied to identify genes beeing significantly affected by pre-slaughter stress or no stress treatment in pigs of different breed (Italian Duroc, Italian Large White or Pietrain) and differnt Halothane genotype (RYR1 locus CC-NN, CT-Nn or TT-nn) in Pietrain pigs.

Project description:Pig breeds have different attitude to traits like growth rate, carcass composition and reproduction parameters as well as other traits. These traits considered as external traits or end phenotypes are the outcome of complex biological processes and interactions. The main goal of pig breeding programs and the basis for crossbreeding is finding a balance between these traits. In pig production, Large White and Duroc breeds are commonly used to optimise respectively fertility and growth ability and differ on several production traits, indeed the first breed as a high fertility characters whereas Duroc is used as terminal sire for her growth performance and good carcass quality traits. In this study, we have used a quantitative label-free LC-MS proteomics approach to characterise and compare the liver proteome of two heavy Italian pig breeds, Italian Duroc and Italian Large White to identify difference due to their different genetic background. This project has received funding from the European Union’s Horizon 2020 research and innovation programme under the Marie Sklodowska-Curie grant agreement No 703094.

Project description:Purpose: this study is to analyze the change of RNA splicing events after disruption of Protein Arginine Methyltranferase 5 (PRMT5) in Plasmodium falciparum. Methods: In this study, the transcriptomes of a PfPRMT5 gene knockout (KO) parasite line with its wildtype control were analyzed by RNAseq.Total RNA were harvested from the asexual parasites at four stages (ring, early trophozoite, late trophozoite, and schizont)(12h, 24h, 36h, and 46h post-invasion) using the Quick-RNA MiniPrep kit (Zymo Research). RNA sequencing libraries were prepared using the KAPA stranded RNA-seq library preparation kit (Roche) with 500 ng RNA from each sample. Illumina adapter sequence removal and quality trimming of reads were performed using Trimmomatic. Only reads that had a minimum length of 50 base pairs were retained. Reads were then mapped to the P. falciparum 3D7 strain reference genome with HISAT2. Results: This RNAseq analysis with strand-specific mRNA libraries from both ΔPfPRMT5 and WT lines showed that >90% of sequencing reads were of high quality for mapping to the P. falciparum genome with nearly 40 times of coverage. This allows us to analyze the change of alternative splicing events (alternative 5' splice site, alternative 3' splice site, retained intron and skipped exon). 800, 1056, 479, and 1158 alternative splicing events (alternative 5' splice site, alternative 3' splice site, retained intron and skipped exon) were altered in the DPfPRMT5 parasite line as compared to the WT line at four development stages, respectively (unpublished data). Conclusions: Collectively, this RNAseq provide a dataset for analysis of abnormal RNA splicing events in the ΔPfPRMT5 parasites.

Project description:The genetic foundation of chicken tail feather color is not very well studied to date, though that of body feather color is extensively explored. In the present study, we used a synthetic chicken dwarf line (DW), which was originated from the hybrids between a black tail chicken breed, Rhode Island Red (RIR) and a white tail breed, Dwarf Layer (DL), to understand the genetic rules of the white/black tail color. The DW line still contain the individuals with black or white tails, even if the body feather are predominantly red, after more than ten generation of self-crossing and being selected for the body feather color. We firstly performed four crosses using the DW line chickens including black tail male to female, reciprocal crosses between the black and white, and white male to female to elucidate the inheritance pattern of the white/black tail. We found that (i) the white/black tail feather colors are independent of body feather color and (ii) the phenotype are autosomal simple trait and (iii) the white are dominant to the black in the DW lines. Furtherly, we performed a genome-wide association (GWA) analysis to determine the candidate genomic regions underlying the tail feather color by using black tail chickens from the RIR and DW chickens and white individuals from DW lines.

Project description:Recent transcriptome analysis indicates that >90% of human genes undergoes alternative splicing, underscoring the contribution of differential RNA processing to diverse proteomes in higher eukaryotic cells. The polypyrimidine tract binding protein PTB is a well-characterized splicing repressor, but PTB knockdown causes both exon inclusion and skipping. Genome-wide mapping of PTB-RNA interactions and construction of a functional RNA map now revealed that dominant PTB binding near a competing constitutive splice site generally induces exon inclusion whereas prevalent binding close to an alternative site often causes exon skipping. This positional effect was further demonstrated by disrupting or creating a PTB binding site on minigene constructs and testing their responses to PTB knockdown or overexpression. These findings suggest a mechanism for PTB to modulate splice site competition to produce opposite functional consequences, which may be generally applicable to RNA binding splicing factors to positively or negatively regulate alternative splicing in mammalian cells.

Project description:Alternative pre-mRNA splicing critically contributes to the generation of protein variety in a tissue- and development-specific manner. Alterations in the normal pathways of alternative splicing (AS) have been associated with the growth and maintenance of several tumour types, and have been indicated as candidate bio-markers of tumour progression, metastasis and patient survival. In this study we applied genome-wide exon array technology to investigate AS events that may distinguish between human medulloblastoma and normal cerebellum. We initially investigated gene-level expression profiles to identify samples expressing gene signatures characteristic of previously described MB molecular subgroups. 3 medulloblastomas significantly over-expressed genes typically belonging to the Shh signalling pathway or associated with a granule cell progenitor status and were therefore classified as Shh-activated tumours (MB1). The remaining tumour samples were grouped together as medulloblastoma subset 2 (MB2). We then applied the Splicing Index algorithm and identified 1260 unique genes containing at least one candidate exon whose inclusion rate differed between different sample subgroups. Following the analysis of candidate event expression plots and gene structure annotation, we selected 14 examples of differential splicing of cassette exons and successfully validated 11 of them by semi-quantitative RT-PCR in a selection of the initial sample-set and subsequently in an independent set of 10 normal cerebellum and 20 medulloblastoma samples. Through the analysis of AS pathway in in vitro cultures of cerebellar granule cell progenitors (the putative cell of origin of least a subset of medulloblastomas), we showed that medulloblastoma-associated AS patterns could be indicative of a normal cerebellar undifferentiated phenotype and suggested that activation of oncogenic pathways during the development of the cerebellum may lead to a failure of neuronal differentiation also through the disruption of AS programs.
