Project description:We consturcted a full-length transcript reference of CD4SP and CD8SP T cells using TGS (PacBio) data. We then used SGS (Illumina) CD4SP and CD8SP data to quantify isoform expressions and study alternative splicing patterns against the full-length transcript reference between CD4SP and CD8SP cells.
Project description:A novel alternative splicing isoform of LOXL2 △e13 was expressed ubiquitously in all cell lines and ESCC tissues. In contrast to the impaired deamination enzymatic activity compared with full length LOXL2, LOXL2 △e13 showed an enhanced ability to promote cell mobility and invasiveness in ESCC cells than full length LOXL2 through a different mechanism.
Project description:Full-Length cDNA transcriptome (Iso-Seq) data sequenced on the PacBio Sequel system using 2.1 chemistry. Multiplexed cDNA library of 12 samples (3 tissues x 4 strains). Tissues: root, embryo, endosperm. Strains: B73, Ki11, B73xKi11, Ki11xB73.
Project description:To analyse the regulation of transcripts in grain embryo and endosperm during development, we performed RNA-Seq for wheat from 14 and 25 day post anthesis (DPA). And long-read sequencing for mixed whole grains from 14 and 25 DPA was employed to obtain full-length transcripts. A series of differentially expressed genes and tissues-specific genes of embryo and endosperm were identified. Moreover, 4351, 4641, 4516 and 4453 genes with A, B and D homoeoloci were detected in the four tissues. These provide specific gene pools of embryo and endosperm and homoeolog expression bias model in a large scale, which provides new insights into the molecular physiology of wheat.
Project description:iRNA approaches were used to knock down the expression of dystrophin (DMD), including its full-length isoform DP427, and utrophin (UTRN) genes. Specifically, iRNA-mediated knockdown of both DMD (full-length dystrophin DP427) and UTRN was performed in HSkM myotubes. It is known that the shorter dystrophin isoform DP71 compensates for full-length dystrophin DP427 in the early stages of myofiber differentiation in cell models of Duchenne muscular dystrophy. Accordingly, DP427-deficient and DP71/DP427-deficient HSkM myotubes exhibit distinct changes in the expression of genes involved in membrane integrity and cytoskeletal functions. RNA-sequencing analyses revealed overlapping transcriptomic alterations in these HSkM cell lines, which corresponded to observed phenotypic abnormalities such as increased membrane permeability and intracellular calcium levels, mitochondrial aggregation, elevated reactive oxygen species (ROS), enhanced cyto- and genotoxicity, and induction of apoptosis.
Project description:To identify aberrant splicing isoforms and potential neoantigens, we performed full-length cDNA sequencing of lung adenocarcinoma cell lines using a long-read sequencer MinION. We constructed a comprehensive catalog of aberrant splicing isoforms and detected isoform-specific peptides using proteome analysis.
