High grade neuroendocrine lung cancer expression profile

Project description:Genomic gains and losses, particularly amplification of oncogenes and deletion of tumor suppressor genes, are critical molecular events involved in tumorigenesis and cancer progression. These genomic structural abnormalities trigger pathway alterations which activate/inactivate transcription factors along protein network, and then affect gene transcription profiles. Therefore, trace-back analysis of the pathway alteration by integrating genomic copy number, transcription profile, and known protein network data is expected to provide key information to interpret tumorigenesis and cancer progression processes. However, there are a number of pathway alteration candidates, so that it is difficult to understand overall picture. Primitive approaches such as filtering by arbitrary selection of thresholds involve a risk of overlooking important pathway alterations and their triggers. We proposed a visualization method for the trace-back analysis of pathway alterations, called a Cluster Overlap Distribution Map (CODM). We applied the CODM to trace-back analysis of pathway alterations related to subtype classifications of high grade neuroendocrine carcinoma samples; 1) small cell lung carcinoma (SCLC) vs. large cell neuroendocrine carcinoma (LCNEC), and 2) group1 vs. group2 (this is the classification based on transcription profiles and group2 has a higher survival rate than group1). By effective use of 3D and color spaces, the CODM allowed us to understand the overall picture of pathway alteration without arbitrary selection of thresholds and to extract 6 pathway alterations related to only group1 vs. groups2, 2 pathway alterations related to only SCLC vs. LCNEC, and 2 pathway alterations related to both group1 vs. group2 and SCLC vs. LCNEC.

Acne flare-up in treatment process: investigating the difference of gene expression in peripheral blood

Project description:Objectives: To identify gene expression changes in acne flare-up patients, thereby exploring the mechanisms of acne flare-up after treatment. Methods: 11 acne patients and 3 healthy people were divided into 4 groups (group1: 4 with flare-up, group2: 4 with improvement, group3: 3 without obvious changes, group4: healthy control). Peripheral blood of patients before and after isotretinoin or minocycline were collected. RNA-seq were used to detect the gene expression. We applied data in self-contrast and intergroup comparisons. Results: In the self-contrast of group1, 22 upregulated genes were involved in Toll-like receptor signaling pathway and inflammatory response. Comparing group1 and group3 before treatment, 1778 upregulated genes enriched in Th17 cell differentiation, while 57 downregulated genes enriched in defensive response to organism. Conclusions: The gene expression profiles of acne flare-up patients changed. Inflammatory, immune responses played a prominent role in acne flare-up process and relatively weak defensive response to microbes, comedogenesis might be risk factors.

Effect of bacteriocin NC8 on human intestinal flora

Project description:Herein, we evaluated the regulation of plantaricin NC8 on gut microbiota by in vitro simulation system, and assessed their modulation on different intestinal types, namely enterotype 1 (ET B) and enterotype 2 (ET P), for the first time. Plantaricin NC8 could not significantly promote or inhibit the production short chain fatty acids (SCFAs) by the gut flora in the fecal samples from eight subjects to produce through Gas chromatography (GC) determining, neither ET B nor ET P. 16S rDNA sequencing showed that plantaricin NC8 shortened the Shannon index of ET B and the Simpson index of ET P, but their β diversity change was not statistically significant. In addition, plantaricin NC8 could promote the growth of beneficial bacteria. Results showed that plantaricin NC8 mainly increased the abundance of Actinobacterias, Bacteroides, Bifidobacterium, Megamonas, Escherichia-Shigella, and decreased the abundance of Streptococcus in ET B. And it also increased the abundance of Prevotella_9, Bifidobacterium, Escherichia-Shigella, Mitsuokella and others in ET P. Plantaricin NC8 can influence intestinal microorganisms, but the influence were different for different enterotypes.

shRNA profiling of human hepatocyte HepG2 cells knocked down for HNF4 to investigate its role in inflammatory response

Project description:To obtain a genomic view of hepatocyte nuclear factor-4Î± (HNF-4Î±) in the regulation of the inflammatory response, microarray analysis was used to probe the expression profile of an inflammatory response induced by cytokines in a model of knock-down HNF-4Î± HepG2 cells. The results indicate an extensive role for HNF-4Î± plays in the regulation of a large number of the liver-specific genes. Majority of genes (71%) affected by cytokine treatment are also affected by HNF-4Î± knock-down. This significant overlap suggests that HNF-4Î± may play a role in regulating the cytokine-induced inflammatory response. Experiment Overall Design: The different treated HepG2 cells were grouped into 4 groups (four replicates in each group): Group1, Control; Group2, HNF-4Î± shRNA treated cells; Group3, cytokine treated group; Group4, HNF-4Î± shRNA and cytokine treatments. RNA extraction and hybridization on Affymetrix microarrays were processed. The expression profiles between different groups were analyzed and compared. In order to explore the function of HNF-4Î± in the inflammatory response, a set of 170 genes annotated as inflammatory response was obtained from GO (geneotology.org), the enrichments of these inflammatory genes were analyzed in different treated groups.

SIRT1 Activation Disrupts Maintenance of Myelodysplastic Syndrome Stem and Progenitor Cells by Restoring TET2 Function [microarray expression profiling]

Project description:Improved understanding of mechanisms regulating myelodysplastic syndrome (MDS) hematopoietic stem/progenitor cell (HSPC) growth and self-renewal is critical for developing MDS therapy. We revealed a novel regulatory axis that SIRT1-deficiency induced TET2 hyperacetylation promotes MDS HSPC functions, and provide an approach to target MDS HSPCs by activating SIRT1 deacetylase. Four Groups: Group1: MDS-L cells transduced with lentiviral vector targeting non-silence squence (control shRNA for SIRT1); Group2: MDS-L cells transduced with lentiviral vector containing interference squence targeting SIRT1 (SIRT shRNA); Group 3: MDS-L cells transduced with lentiviral vector targeting non-silence squence (control shRNA for TET2); Group 4: MDS-L cells transduced with lentiviral vector containing interference squence targeting TET2 (TET2 shRNA).
