Project description:D-galactose orally intake ameliorate DNCB-induced atopic dermatitis by modulating microbiota composition and quorum sensing. The increased abundance of bacteroidetes and decreased abundance of firmicutes was confirmed. By D-galactose treatment, Bacteroides population was increased and prevotella, ruminococcus was decreased which is related to atopic dermatitis.

Project description:We report the recovery of metagenome-assembled genomes (MAGs) from fecal samples collected in 2018 from five healthy adult female pigs in southeast England. The resulting nonredundant catalog of 192 MAGs encompasses 102 metagenomic species, 41 of them novel, spanning 10 bacterial and 2 archaeal phyla.

Project description:Protein inhibitor of activated STAT (PIAS) are E3 SUMO ligases playing important roles in protein stability and signaling transduction pathways. PIAS proteins are overexpressed in the triple-negative breast cancer cell line MDA-MB-231, and PIAS knockout (KO) results in a reduction in cell proliferation and cell arrest in S phase. However, the molecular mechanisms underlying PIAS functions in cell proliferation and cell cycle remain largely unknown. Here, we used quantitative SUMO proteomics to explore the regulatory role of PIAS SUMO E3 ligases upon CRISPR/Cas9 KO of individual PIAS. A total of 1422 sites were identified, and around 10% of SUMO sites were regulated following KO of one or more PIAS genes. We identified protein substrates that were either specific to individual PIAS ligase or regulated by several PIAS ligases. Ki-67 and TOP2A, which are involved in cell proliferation and epithelial-to-mesenchymal transition, are SUMOylated at several lysine residues by all PIAS ligases, suggesting a level of redundancy between these proteins. Confocal microscopy and biochemical experiments revealed that SUMOylation regulated TOP2A protein stability, while this modification is involved in the recruitment of Ki-67 nucleolar proteins containing SUMO interacting motif. These results provide novel insights into both the redundant and specific regulatory mechanisms of cell proliferation and cell cycle mediated by PIAS SUMO E3 ligases.

Project description:Activation of the serine/threonine kinase Akt contributes to the formation, maintenance, and therapeutic resistance of cancer, which is driving development of compounds that inhibit Akt. Phosphatidylinositol ether lipid analogues (PIAs) are analogues of the products of PI3K that inhibit Akt activation, translocation, and the proliferation of a broad spectrum of cancer cell types. To gain insight into the mechanism of PIAs, time-dependent transcriptional profiling of 5 active PIAs and the PI3K inhibitor LY294002 (LY) was performed in non-small cell lung cancer (NSCLC) cells using high-density oligonucleotide arrays. Gene ontology analysis revealed genes involved in apoptosis, wounding response, and angiogenesis were upregulated by PIAs, while genes involved in DNA replication, repair and mitosis were suppressed. Genes that exhibited early differential expression were partitioned into 3 groups; those induced by PIAs only (DUSP1, KLF6, CENTD2, BHLHB2, PREX1), those commonly induced by PIAs and LY (TRIB1, KLF2, RHOB and CDKN1A), and those commonly suppressed by PIAs and LY (IGFBP3, PCNA, PRIM1, MCM3 and HSPA1B). Increased expression of the tumor suppressors RHOB (RhoB), KLF6 (COPEB) and CDKN1A (p21Cip1/Waf1) was validated as an Akt-independent effect that contributed to PIA-induced cytotoxicity. Despite some overlap with LY, active PIAs have a distinct expression signature that contributes to their enhanced cytotoxicity.

H157 cells were plated at 2x10^6 in T-75 flasks in RPMI medium 1640 containing 10% FBS and incubated for 24h. The media was then changed to RPMI medium 1640 with 0.1% FBS and the cells were incubated overnight. The following morning, cells were treated with 10 microM PIA6 dissolved in DMSO for 0h, 2h, 6h or 12h, and an equal volume of DMSO was added to control samples. For the PIA comparison, 10 microM PIAs (5, 6, 7, 23, 24, 25) or 10 microM LY294002 (LY) were incubated with the cells for 6h. In the PIA comparison experiment, the same concentration of PIA7 (an inert analog consisting of only the lipid side chain) was used as a control. Following incubation, the alterations in cellular morphology were photographed, and cells from 6-well plates were harvested for immunoblot analysis. Total RNA was extracted from cells treated in T-75 flasks using TRIzol reagent (Invitrogen) and chloroform, and purified according to the RNeasy midiprep spin kit protocol (Qiagen). Oligonucleotide microarray was performed with dye-swap. Microarray chips were generated from the 34,580 longmer probe set Human Genome Oligo Set Version 3.0 (Qiagen). Protocols for cDNA labeling, hybridization, and scanning are available through the National Human Genome Research Institute microarray core.
