Spatial Transcriptomics of Pancreatic Tumors Reveal Distinct Compartmentalisation of Neutrophil Subsets [Spatial Transcriptomics]

ABSTRACT: Neutrophils are increasingly recognized as key players in the tumour immune response, and are associated with poor clinical outcomes. Multiple studies have characterised various neutrophil states within the tumor, with associated pro- and anti- tumoral functions. However, it is unknown if this heterogeneity of neutrophils is contributed by their surrounding tumor microenivironment. To answer this, we performed 10X Visium spatial transcriptomics on a murine model of pancreatic cancer. We discovered that terminally differentiated T3 neutrophils localise primarily in regions near hypoxic and glycolytic areas, while transitional immature T1 and mature T2 neutrophils localise towards the peripheral regions of the tumors. This results points to a spatially dependent role of T3 neutrophils, which may be critical to carry out pro-tumorigenic functions.

Liver Chromatin accessibility landscapes during onset of salmon maturation

Project description:We sequenced 12 ATAC-Seq lbraries from four biological replicates before (T1) and after the onset of maturation (T2, T3, T4) from liver. To characterise changes in chromatin state following long light initiation, we defined differentially accessible regions (DARs) where mapping counts differed significantly between T1 and other time points. This revealed a strong early remodelling in the chromatin state landscape, as most DARs were observed at T2 (n=1501) before decreasing in stepwise fashion at T3 (n=477) and T4. The majority of DARs (n=1036 or 57%) exhibit reduced accessibility at T2 compared with T1 and subsequently remained unchanged at later time points (Fig. 5a; Supplementary Figure S14). Similarly, regions that gained accessibility at T2 (n=696 or 38%) also remained unchanged at later timepoints. This left less than 10% of DARs (n=99) that displayed an oscillating pattern following the onset of the maturation. Together, this revealed the ATAC-seq signatures were predominantly stable chromatin state changes.

Whole blood transcriptomics to define adaptive biochemical pathways of exercise during aging

Project description:The aim of the current study was to characterize the genetic adaptive pathways altered by exercise in veteran athletes and age-matched untrained individuals. Two groups of 50-60 year old males: competitive cyclists and untrained, minimally active individuals were examined. All participants completed an acut bout of submaximal endurance exercise and blood samples pre- and post-exercise were analyzed for gene expression changes utilizing genome-wide DNA microarray analysis. Our results indicate distinct differences in gene expression involving energy metabolism, lipids, insuling signaling and cardiovascular function between the two groups. These findings may lead to new insights into beneficial signaling pathways of healthy aging and help identify surrogate markers for monitoring exercise and training load. Blood samples from the control and athlete groups were analyzed at three time-points: T1 (before exercise); T2 (immediately after exercise) and T3 (24 hours after exercise). There were n = 4 samples in each of control and athlete group at T1 and T3; and n = 7 for control group and n = 8 for athlete group at T2. One athlete sample (Sample # 010201) at time - point T2 had a technical replicate.

Differential expression profiles and functional prediction of tRNA-derived small RNAs in plasma of patients with aortic dissection during deep hypothermic circulatory arrest

Project description:The purpose of this study was to detect the expression profile of tsRNA during deep hypothermia circulatory arrest, and to find possible regulatory factors according to the changes in its expression level, in the hope of providing an effective organ protection strategy for this process.Three blood samples were collected from a central veins line into ethylenediaminetetraacetic acid (EDTA) tubes as follows: T1 (before starting circulatory arrest), T2 (15 min after initiation of DHCA), T3 (after declamping the left common carotid artery and before rewarming). A total of 286 commonly expressed tsRNAs were identified in the T1 and T2 groups, 68 tsRNAs specifically expressed in the T1 group, and 44 tsRNAs specifically expressed in the T2 group. A total of 290 commonly expressed tsRNAs were identified in the T2 and T3 groups, 64 tsRNAs specifically expressed in the T2 group, and 43 tsRNAs specifically expressed in the T3 group. Next, four tsRNAs were selected to be verified by qRT-PCR. In summary, this study innovatively proposed the correlation between the deep hypothermic circulatory arrest process and the expression profile of tsRNA, and evaluated the expression level and regulation mode of tsRNA. A preliminary exploration of its potential biological role in the process of deep hypothermic circulatory arrest has been carried out, which can provide a better basis and a more comprehensive explanation for the organ protection mechanism of deep hypothermic circulatory arrest. And in further research, we are expected to achieve targeted protection of organs by overexpressing or inhibiting the corresponding tsRNA.

Human marginal zone B cell development from early T2 progenitors [MZBTraj]

Project description:B cells emerge from the bone marrow as transitional (TS) B cells that differentiate through T1, T2 and T3 stages to become naïve B cells. We have identified a bifurcation of human B cell maturation from the T1 stage forming IgMhi and IgMlo developmental trajectories. IgMhi T2 cells have higher expression of a4b7 integrin and lower expression of IL4 receptor (IL4R) compared to the IgMlo branch and are selectively recruited into gut-associated lymphoid tissue. IgMhi T2 cells also share transcriptomic features with marginal zone B cells (MZB). Lineage progression from T1 cells to MZB via an IgMhi trajectory is identified by pseudotime analysis of scRNA-sequencing data. Reduced frequency of IgMhi gut homing T2 cells is observed in severe SLE and is associated with reduction of MZB and their putative IgMhi precursors. The collapse of the gut-associated MZB maturational axis in severe SLE affirms its existence in health.

sRNA sequencing of mature and developing gonads during protandrous changes in the Asian seabass

Project description:Purpose: sRNA-sequencing of mature and intermediate gonadal tissue in order to identify the differential expression of miRNAs during male to female (i.e. protandrous) sex transition Methods: Total RNA was extracted and sRNA was purified. cDNA libraries were constructed using a high definition adapter protocol (Xu et al. 2015). 50 bp sequencing was performed on Illumina's HiSeq 2500 at the Earlham Institute, Norwich, UK. Sequenced data was trimmed for adapters and filtered to remove very short and low complexity sequences. miRBase animal miRNA precursor sequences were mapped against the Asian seabass genome in order to generate a set of putative miRNA precursors. Putative precursor molecules with aligning mature miRBase miRNA(s) and forming a valid pre-miRNA hairpin structure were annotated as valid precursor miRNAs. Novel precursor and mature miRNAs were annotated using a combination of published algorithms and manual checking to ensure consistency with canonical miRNA biogenesis criteria. The alignment of sequenced reads against a non-redundant miRNA precursor set was used to determine raw read counts of mature miRNAs. Differential expression analysis was performed in order to identify differentially expressed mature miRNAs between conditions. Results: We detect 156, 71, 122, 151, 171 and 155 differentially expressed miRNA for the testis -> T1/T2, T1/T2 -> T3/T4, T3/T4 -> ovary, testis -> T3/T4, T1/T2 -> ovary and the testis->ovary comparisons respectively Conclusions: There is substantial differential expression of miRNAs at every stage of gonadal change in the Asian seabass during the sex transition process
