Next Generation Sequencing for Transcriptomes Analysis in GLP-1 Notch receptor ON and OFF genetic background

Project description:Purpose: Ultilize the Next Generation Sequencing to determine the genes that are activated or repressed by GLP-1 Notch receptor in C. elegans germline. The list of genes generated from RNA-seq were intersected with the LAG-1 germline ChIP-seq data to identify direct transcriptional targets of the GLP-1/LAG-1 transcriptional complex in C. elegans germline stem cells. Methods: RNA isolated from hand dissected C. elegans germline tumor (one day old adult animals) are used for RNA-seq library. Results: 94 genes were identified as activated by GLP-1 Notch receptor from 5 biological replicates with the following criteria: gene counts per million greater than 2.0; fold of change greater than 2.0; false discovery rate (FDR) <0.05. Conclusions: lst-1 and sygl-1, two previously reported genes, were identified as direct transcriptional target for GLP-1/LAG-1 in C. elegans germline stem cells.

Neuronal Acetylcholine Couples Gonadal Gap Junction/Notch Signaling Axis to Gut Defense

Project description:Gap junctions mediate intercellular communications across cellular networks in the nervous and the immune systems, while the role in the intestinal innate immunity is poorly understood. Here, we identified that an innexin gene inx-14 encoding one of heterotypic and heteromeric gap junction subunits acts in the gonad to attenuate the intestinal defense through PMK-1/p38 pathway. The RNA-seq analyses revealed that GLP-1/Notch signaling was downregulated, while lysosome, and PMK-1/p38 MAPK signalings were upregulated by the germline-specific inx-14 RNAi in C. elegans. Loss function of either inx-14, or glp-1 exhibited enhanced resistance to PA14 infection and upregulated lysosome and PMK-1/p38 signalings. Additionally, inx-14 knockdown by germline specific RNAi upregulated muscarinic acetylcholine receptor (mAChR) genes gar-1/gar-2/gar-3. We further revealed that acetylcholine mAChR GAR-2/GAR-3 signaling functions in the intestine and downstream of lysosome signaling but upstream of PMK-1/p38 pathway to facilitate the intestinal defense. Our findings reveal a novel role for gonadal gap junction/INX-14 in host intestinal defense against pathogens and expand our understanding the functions of reproductive system in the host intestinal defense.

The Insulin/IGF Signaling Cascade Modulates SUMOylation to Regulate Aging and Proteostasis in C. elegans.

Project description:In this project we asked how reducing the activity of the insulin/IGF signaling (IIS) cascade by knocking down the expression of daf-2, affects global protein SUMOylation of C. elegans. We found that among other proteins, IIS reduction lowers the SUMOylation of CAR-1, a protein that negatively regulates the activity of the worm’s notch receptor, GLP-1. Thus, the knockdown of car-1 hyper-activates GLP-1, shortens lifespan and exposes the worm to toxic protein aggregation (proteotoxicity). In contrast, the expression of a SUMOylation resistant CAR-1 (K185R) promotes longevity and protects model nematodes from proteotoxicity.

Microarray analysis of Caenorhabditis elegans recombinant inbred lines exposed to gld-1 or empty-vector RNAi

Project description:The glp-1/NOTCH pathway is a conserved pathway that plays an important role in developmental control. To study the effect of natural genetic variation on perturbations in this pathway, we used N2xCB4856 recombinant inbred lines of the nematode Caenorhabditis elegans. These were treated with empty vector or gld-1 RNAi, where gld-1 is a key developmental gene in the glp-1/NOTCH pathway. The recombinant inbred lines were exposed for two generation to the treatment and 47 hour old L4 juveniles were collected for RNA isolation. In total 39 RILs were exposed to the empty-vector treatment and 46 RILs were exposed to the gld-1 treatment. Gene expression was quantified using microarrays.

Genome-wide analysis of germ cell proliferation in C. elegans

Project description:Proliferating germ cells in C. elegans provide a useful model system for deciphering fundamental mechanisms underlying the balance between proliferation and differentiation. Using gene expression profiling of mutants with excess germ cell proliferation, we identified approximately 200 genes expressed in the proliferating germ cells of C. elegans. RNA isolated from young adult C. elegans hermaphrodites of the genotype unc-32(e189) (control) and from unc-32(e189)glp-1(oz112gf) (excess germ cell proliferation) was directly compared on DNA arrays representing >90% of C. elegans genes. Four biological replicates were performed, with balanced dye swaps.

C. elegans small RNA-seq profiling of three different lotr-1 mutant alleles

Project description:Proteins containing LOTUS and Tudor domains have critical roles in the germline, including in small RNA biology. LOTR-1 is the only protein expressed in the germline of C. elegans which has LOTUS and Tudor domains. Here, to understand the influence of LOTR-1 in small RNA biology, we sequenced small RNAs of wild-type and lotr-1 mutant animals.
