Project description:In the fire ant Solenopsis invicta, a colony queen number is determined by the founding queen's genotypes at the 13 Mb supergene with the non-recombining variants SB and Sb. Single-queen colonies are always headed by SB/SB queens while multiple-queens colonies are always headed by SB/Sb queens. The two variants of the supergene, SB and Sb are completely linked to the two alleles (B and b) of the gene Gp-9. SB/SB and SB/Sb queens differ in many physiological traits including their maturation rate and odor. To explain why SB/SB and SB/Sb queens have different odors, and why SB/SB virgins mature faster and accumulate more fat, we measured expression of ~6000 genes in virgin queens 1 and 11 days after eclosion and in reproductive queens. Keywords: fire ants, Solenopsis invicta, Supergene, queen, Gp-9, social form, maturation, fat storage, queen odor, cuticular hydrocarbon, worker discrimination, monogyne, polygyne, transposon, chemical signaling

Biological replicates: 8 for 1-day-old SB/SB virgins and 1-day-old SB/Sb virgins that were collected in 2008; 8 for 1-day-old SB/SB virgins, 1-day-old SB/Sb virgins that were collected in 2009; 7 for 11-day-old SB/SB virgins and 11-day-old SB/Sb virgins that were collected in 2008; 8 for 11-day-old SB/SB virgins and 11-day-old SB/Sb virgins that were collected in 2009; 8 for SB/SB and SB/Sb reproductive queens (only collected in 2009). Samples were labeled with Cy3 and were compared to the same common reference RNA labeled with Cy5. Samples from 2008 were hybridized on the microarrays batch I and samples from 2009 were hybridized on the microarrays batch J.

Project description:In vertebrates, non-lens bg-crystallins are widely expressed in various tissues, but their functions are unknown. The molecular mechanisms of trefoil factors, initiators of mucosal healing and being greatly involved in tumorigenesis, have remained elusive.A naturally existing 72-kDa complex of non-lens bg-crystallin (a-subunit) and trefoil factor (b-subunit), named bg-CAT, was identified from frog Bombina maxima skin secretions. Its a-subunit and b-subunit (containing three trefoil factor domains), with a non-covalently linked form of ab2, show significant sequence homology to ep37 proteins, a group of non-lens bg-crystallins identified in newt Cynops pyrrhogaster and mammalian trefoil factors, respectively. The bg-CAT showed multiple cellular effects on human umbilical vein endothelial cells. Low dosages of bg-CAT (25-50 pM) were able to stimulate cell migration and wound healing. At high concentrations, it induced cell detachment (EC50 10 nM) and apoptosis. The bg-CAT was rapidly endocytosed via intracellular vacuole formation. Under confocal microscope, some of the vacuoles were translocated to nucleus and partially fused with nuclear membraneï®. However, what exactly target of bg-CAT act on HUVECs nuclear is still unknown. Primary cultured HUVECs treated with bg-CAT (25 nM, 2 h) were selected for RNA extraction and hybridization on Affymetrix microarrays. We sought to obtain the genome wide level of significant differential gene expression induced by bg-CAT on HUVECs in order to get clues about bg-CAT action mechanisms. These findings illustrate novel cellular functions of non-lens bg-cyrstallins and action mechanism via association with trefoil factors, serving as clues for investigating the possible occurrence of similar molecules and action mechanisms in mammals. Experiment Overall Design: We used microarrays to analysis genome wide level of significant differential gene expression induced by bg-CAT on HUVECs.Four independent biological replicates of HUVECs treated with bg-CAT (25 nM, 2 h) were compared with normal control by SAM. The significant differential expression of 123 genes (fold changeâ¥3, q value =0, FDR (false discovery rate)=0). 121 genes were up-regulated, among which members of nuclear receptor subfamily 4 (NR4A) were the most prominent. Only 2 genes were down-regulated (including collagen type I) (Supporting information Fig. S1 and Table S1 in accompanying publication). Members of NR4A exhibit differential roles in determining cell growth or cell death depending on its location in the nucleus or mitochondria. NR4A1 (also called Nur77, TR3) mediates cell apoptosis through translocation from nucleus to mitochondria and induction of cytochrome c releasing . Significant activation of NR4A members suggests these orphan nuclear receptors may be involved in the mediation of bg-CAT biological functions, like proapoptotic action of the protein at high concentrations. Up-regulated expression of a number of matrix metalloproteinases by bg-CAT could facilitate cell migration and detachment. The bg-CAT also induced the expression of a number of cytokines, including interleukin 1, interleukin 8 and interleukin 6, as well as various chemokines in HUVECs. These data provide clues for study in detail of molecular pathways through which bg-CAT exerts its biological functions.

Project description:We present the 3.3 Å cryo-EM structure of an AA amyloid extracted post-mortem from the diseased kidney of a DSH cat with renal failure. The structure reveals a cross-beta architecture assembled from two 76-residue long proto-filaments. Despite >70% sequence homology to mouse and human SAA, the cat SAA variant adopts a unique amyloid fold exhibiting type-2 polymorphism. Based on shared disease profiles and almost identical sequences, we propose a similar amyloid fold of deposits identified previously in captive cheetah.

Project description:Antimony (Sb) pollution, especially released from mining activities has already been widely recognized as a global concern. To gauge strategies for the remediation of an Sb-contaminated ecosystem, the exploration of native microbiota Sb(III) resistance mechanism is of great significance. Acinetobacter is one of the bacterial genera abundantly thriving in Sb(III)-contaminated environments, the scientific elaboration of Sb(III)-resistance mechanisms of Acinetobacter is imperative. Proteomics experiment was performed (Acinetobacter johnsonii JH7 with and without Sb(III) addtion) to probe its pattern of proteins change under Sb(III) stress. We hope that the mechanisms of Sb(III) resistance of Acinetobacter could be revealed by using iTRAQ this time.
