Tubastraea coccinea is an azooxanthellate coral species recorded in the Indian and Atlantic oceans and is presently widespread in the southwestern Atlantic with an alien status for Brazil. T. coccinea outcompete other native coral species by using a varied repertoire of biological traits. For example, T. coccinea has evolved potent venom capable of immobilizing and digesting zooplankton prey. Diversification and modification of venom toxins can provide potential adaptive ben ...[more]

Transcription profiling of rat at pheochromocytoma cell line PC12 treated with trimethyltin at low and high doses

Project description:The rat pheochromocytoma cell line PC12 cells were cultured in complete DMEM till 80% confluence, then placed at 5000 cells per squared cm. Cells were then plated in 24-well plates for cell viability assay and in T75 flasks for RNA isolation. Medium was replaced with serum-free fresh medium for 12 hours prior to TMT treatment. Gene expression patterns were then analysed using Rat Expression Array 230A Experiment Overall Design: In this study we analize gene expression patterns in PC12 cells treated with Trimethyltin (TMT). We utilized control cells (untreated) and two different concentration (1 and 5) Experiment Overall Design: We used three biological replicates, for the three concentration tested, according to MIAME guidelines Experiment Overall Design: (total 9 chips were used in this study).

Microarray analysis of the effects of a Î³-tocopherol-rich mixture of tocopherols on global gene expression in the prostates of TRAMP mice

Project description:We used whole mouse genome microarrays to the effects of Î³-TmT on global gene expression in the prostate TRAMP and age-matched C57BL/6 mice were administered either 600 mg/kg of Î³-TmT or a control vehicle via oral gavage. Twelve hours after dosing, prostate tissues were collected for RNA extraction.

African swine fever virus ubiquitinconjugating enzyme interacts with host translation machinery to regulate the host protein synthesis

Project description:African Swine Fever virus (ASFV) causes one of the most relevant emerging diseases affecting swine, now extended through three continents. The virus has a large coding capacity to deploy an arsenal of molecules antagonizing the host functions. In the present work, we have studied the only known E2 viral-conjugating enzyme, UBCv1 that is encoded by the I215L gene of ASFV. SILAC quantitative proteomics was used toidentify and characterize novel UBCv1-host interactors. The analysis revealed interaction with the 40S ribosomal protein RPS23, the cap-dependent translation machinery initiation factor eIF4E, and the E3 ubiquitin ligase Cullin 4B. Our data show that during ASFV infection, UBCv1 was able to bind to eIF4E, independent from the cap-dependent complex. Our results provide novel insights into the function of the viral UBCv1 in hijacking cellular components that impact the mTORC signalling pathway, the regulation of the host translation machinery, and the cellular protein expression during the ASFV lifecycle. The people involved in this project are: Lucia Barrado-Gil, Covadonga Alonso and Carlos Maluquer de Motes.

Human glioma cells treated with irradiation and/or CCI-779

Project description:Gene expression profiling of human glioma cell line LN-308. Cells were treated with the mTOR inhibitor CCI-779 or irradiated with a single dose of 4 Gy or a combination of both. The objective of this studywas to evaluate CCI-779 as a radio-sensitizing agent and to elucidate the underlying mechanisms. Irradiated, CCI-779-, DMSO- (vehicle control) or combination treated LN-308 samples were hybridized against pooled untreated LN-308 samples as reference (CCI+Irradiation vs. Ref; CCI vs. Ref; DMSO+Irradiation vs Ref; DMSO vs. Ref).Three independent replicates were generated for each treatment and control, respectively.

Alkaloids modify the poison frog proteome

Project description:Poison frogs sequester chemical defenses from their diet of leaf litter arthropods for defense against predation. Little is known about the physiological adaptations that confer this unusual bioaccumulation ability. We conducted an alkaloid-feeding experiment with the Diablito poison frog (Oophaga sylvatica) to determine how quickly alkaloids are accumulated and how toxins modify frog physiology using quantitative proteomics. Diablito frogs rapidly accumulated the alkaloid decahydroquinoline within four days, and dietary alkaloid exposure modified protein abundance in the intestines, liver, and skin. Many proteins that increased in abundance with toxin accumulation are plasma glycoproteins, including the complement system and the toxin-binding protein saxiphilin. Other protein classes that change in abundance with toxin accumulation are membrane proteins involved in small molecule transport and metabolism. Overall, this work shows poison frogs can rapidly accumulate alkaloids, which alter carrier protein abundance, initiate an immune response, and alter small molecule transport and metabolism dynamics across tissues

Flexible B12 ecophysiology of Phaeocystis antarctica due to a B12-independent methionine synthase fusion protein with widespread homologues

Project description:Coastal Antarctic marine ecosystems play an important role in carbon cycling due to their highly productive seasonal phytoplankton blooms. Southern Ocean microbes are primarily limited by light and iron (Fe) and can be co-limited by cobalamin (vitamin B12 ). Micronutrient limitation is a key driver of ecosystem dynamics and influences the composition of blooms, which are often dominated by either diatoms or the haptophyte Phaeocystis antarctica, each with varied impacts on carbon cycling. However, the vitamin requirements and ecophysiology of the keystone species P. antarctica remains poorly characterized. Using cultures, physiological analysis, and comparative ’omics we examined the response of P. antarctica to a matrix of Fe-B12 conditions. We show that P. antarctica is not auxotrophic for B12 , as previously suggested, and report new mechanistic insights of its B12 response in cultures of predominantly solitary and colonial cells. Proteomics coupled with proteogenomics detected a B12 -independent methionine synthase fusion protein (MetE-fusion) that is expressed under vitamin limitation and is interreplaced with the B12 -dependent isoform (MetH) in replete conditions. Database searches returned homologs of the MetE-fusion protein in multiple Phaeocystis species and in a wide range of marine microbes, including other photosynthetic eukaryotes with polymorphic life cycles and also bacterioplankton. Furthermore, MetE-fusion homologs were found to be expressed in metaproteomic and metatranscriptomic field samples in polar and more geographically widespread regions. As climate change impacts micronutrient availability in the coastal Southern Ocean, our finding that P. antarctica has a flexible B12 metabolism has implications for its relative fitness compared to B12 -auxotrophic diatoms.
