The transcriptome-wide CPSF6-induced APA alterations in gastric cancer cells

ABSTRACT: In this study, we showed that knockdown of CPSF6 inhibited GC cell growth and promoted apoptosis in vitro and in vivo. In order to understand the underlying mechanisms of CPSF6, we performed an APA profiling analysis in wild-type and CPSF6-knockdown AGS cells, using 3T-seq method.

A Transcriptomic Analysis of NET1 (a RhoA GEF Exchange Factor) in AGS Gastric Cancer Cells

Project description:Stable knockdown of NET1, a RhoGEF, was achieved in AGS Gastric Cancer cells. This gene is known to be overexpressed in the disease. Knockdown was achieved using lentiviral shRNA particles. Gene expression was compared between knockdown and scrambled shRNA treated control cells. Cells were treated with and without LPA, a known activator of RhoA. Three distinct cell lines were used in this study (all AGS cells); (i) Non Target cell (NT) stably expressing non targetting shRNA (ii) 63 and (iii) 65; the latter two are stable NET1 knockdown cells and are seperatly transduced with separate NET1 targetting shRNA particles. Cells were treated with and without 10microM LPA for 4 hr. Experimental replicates were performed for each treatment (A & B), RNA was prepared from each and seperatly hybridised to U133A arrays.

Quantitative proteomic Analysis Reveals up-regulation of caveolin-1 in FOXP3-overexpressed human gastric cancer cells

Project description:Forkhead box protein 3 (FOXP3) is implicated in tumor progression and prognosis in various types of tumor cells. We have recently reported that FOXP3 inhibited proliferation of gastric cancer (GC) cells through activating the apoptotic signaling pathway. In this study, we found that over-expression of FOXP3 inhibited GC cell migration, invasion and proliferation. Then, the label-free quantitative proteomic approach was employed to further investigating the down-stream proteins regulated by FOXP3, resulting in a total of 3,978 proteins quantified, including 186 significantly changed proteins. Caveolin-1 (CAV1), as a main constituent protein of caveolae, was one of those changed proteins up-regulated in FOXP3-overexpressed GC cells, moreover, it was assigned as one of the node proteins in the protein-protein interaction network and the key protein involved in focal adhesion pathway by bioinformatics analysis. Further biological experiments confirmed that FOXP3 directly bound to the promoter regions of CAV1 to positively regulate CAV1 transcription in GC cells. In summary, our study suggested that FOXP3 can be considered as a tumor suppressor in GC via positively regulating CAV1 through transcriptional activation, and this FOXP3-CAV1 transcriptional regulation axis may play an important role in inhibiting invasion and metastasis of GC cells.

RNA and cell free miRNA in one family of Kallmann's syndrome

Project description:Kallmann Syndrome (KS) is a rare human genetic disorder characterized by the hypogonadotropic hypogonadism with the reduction or absence of olfactory sense. The mutations on the multiple genes including Chemokine Prokineticin-2 (PROK2) were considered to contribute to the abnormal migration of gonadotropin-releasing hormone (GnRH) neurons in embryonic stage. Here, we submit RNA-seq of the peripheral blood and the cell free miRNA-seq in the serum of one family, in which the KS patient has the same mutation of PROK2 (c.223-4C>A) with his mother, and the genetic phenotype of his father is normal. The sexual development and function of his parents are normal.

The Plasmodium falciparum Nuclear Protein Phosphatase NIF4 is Required for Efficient Merozoite Invasion and Regulates Artemisinin Sensitivity

Project description:Artemisinin resistance in Plasmodium falciparum, clinically presented as prolonged parasite clearance half-life, has been associated with a mutation in the NLI-interacting factor-like phosphatase PfNIF4, in addition to the mutations in the Kelch13 protein as the major determinant. We found that PfNIF4 predominant expression at the schizont stage and localized in the nuclei of the parasite. To elucidate the functions of PfNIF4 in P. falciparum, we performed PfNIF4 knockdown (KD) using the inducible ribozyme system. PfNIF4 KD attenuated merozoite invasion and affected gametocytogenesis. PfNIF4 KD parasites also showed significantly increased in vitro susceptibility to artemisinins. Transcriptomic analysis revealed that PfNIF4 KD led to significant changes in the expression of approximately 10-25% of parasite genes during the IDC. At the schizont stage, down-regulated genes were significantly enriched in the invasion-related terms, while at the trophozoite and schizont stages, pathways associated with artemisinin resistance (e.g., mitochondrial function, membrane, and Kelch13 interactome) were also down-regulated. Consistent with PfNIF4 being a protein phosphatase, PfNIF4 KD resulted in an overall up-regulation of the phosphoproteome of infected erythrocytes. Specifically, we observed increased phosphorylation of Ser2/5 of the tandem repeats in the Rpb1 C-terminal domain (CTD) of RNA polymerase II (RNAPII) upon PfNIF4 KD. Furthermore, using the TurboID-based proteomic approach, we identified that PfNIF4 interacted with the RNA polymerase II (RNAPII) components, AP2-domain transcription factors, and chromatin-modifiers and binders. These findings suggest that PfNIF4 may act as the RNAPII CTD phosphatase, regulating the expression of general and parasite-specific cellular pathways during the blood-stage development.

An integrative omics approach reveals posttranscriptional mechanisms underlying circadian temperature compensation

Project description:We apply 3'-End-RNA-seq based sequencing to globally quantify polyadenylation sites and transcript isoform abundance in human U-2 OS cells under wild-type and CPSF6 knock-down conditions at 3 different temperatures (32°C, 37°C and 39°C). We show that CPSF6 knock-down as well as temperature alterations lead to global changes in 3' UTR length and transcript abundance. By means of a differential response analysis with respect to temperature changes in wild type and temperature-decompensated CPSF6 knockdown cells, we reveal candidate genes underlying circadian temperature compensation.

Gut microbiota dysbiosis and neurological function recovery after intracerebral hemorrhage [16S rRNA-Seq]

Project description:We aimed to investigate the microbial community composition in patients with intracerebral hemorrhage (ICH) and its effect on prognosis. The relationship between changes in bacterial flora and the prognosis of spontaneous cerebral hemorrhage was studied in two cohort studies. Fecal samples from healthy volunteers and patients with intracerebral hemorrhage were subjected to 16S rRNA sequencing at three time points: T1 (within 24 hours of admission), T2 (3 days post-surgery), and T3 (7 days post-surgery) using Illumina high-throughput sequencing technology.

ChIP-seq in wild type and Bmi1 knockdown undifferentiated spermatogonia

Project description:Mammalian spermatogenesis is regulated by epigenetic mechanisms that maintain cell type-specific transcriptional programs. The epigenetic regulator BMI1, a PRC1 member, is required for maintaining undifferentiated spermatogonia, but the underlying mechanisms remain unclear. To address this issue, here we performed chromatin immunoprecipitation followed by massive parallel sequencing (ChIP-seq).
