Project description:Salvia is an important genus from the Lamiaceae with approximately 1000 species distributed globally. Several Salvia species are commercially important because of their medicinal and culinary properties. We report the construction of the first fingerprinting array for Salvia species enriched with polymorphic and divergent DNA sequences and demonstrate the potential of this array for fingerprinting several economically important members of this genus.
Project description:The standard treatment for thyroid eye disease is glucocorticoid administration, however its response varies from case to case. In recent years, treatment of thyroid eye disease has evolved dramatically, and the efficacy of several agents is being demonstrated. If steroid resistance is identified prior to treatment, the quality of care can be improved by using other agents as first-line therapy. We performed DIA proteome analysis on pretreatment sera of glucocorticoids response and resistance patients to search for candidate biomarkers of therapeutic response. Sera from healthy subjects and those with Graves' disease without thyroid eye disease are also analyzed together as controls.
Project description:We used array-based comparative genomic hybridization (arrayCGH) of 76 hepatocellular carcinomas (HCCs) to search for genetically disrupted genes.
Project description:Thirteen HER2 positive breast cancer cell lines were screened with 22 commercially available compounds, mainly targeting proteins in the ErbB2 signaling pathway, and the molecular mechanisms related to treatment response were sought. To search for response predictors, genomic and transcriptomic profiling, PIK3CA mutations and PTEN status were associated to the drug responses and several genes involved in the response of the compounds were identified. Array-CGH experiments of HER2+ breast cancer cell lines grown under standard conditions.
Project description:Shellfish allergy is a significant public health concern, yet the molecular basis of allergenicity in molluscs remains poorly defined. In this study, we performed an in-depth proteomic and immunoinformatic analysis of two widely consumed blood clam species, Anadara broughtonii and Tegillarca granosa, to identify and characterize novel allergen candidates. Using high-resolution tandem mass spectrometry, we generated comprehensive protein profiles and applied three complementary allergen prediction algorithms (SEP-AlgPro™, AllerCatPro,and AlgPred 2.0) to screen for potential IgE-binding proteins. Immunoblotting with sera from shrimp-sensitized individuals confirmed IgE reactivity for nine proteins, including catalase and several hemoglobin isoforms—none of which are currently recognized as molluscan allergens. Homology modeling and sequence alignment revealed conserved structural motifsimplicated in allergenicity and suggested cross-reactivity with known crustacean allergens. These findings expand the repertoire of putative molluscan allergens and demonstrate theutility of integrated proteomic and immunoinformatic strategies for allergen discovery.
Project description:Genomic disorders are characterized by the presence of flanking segmental duplications that predispose these regions to recurrent rearrangement. Based on the duplication architecture of the genome we investigated 130 regions which we hypothesized as candidates for novel genomic disorders 1. We tested 290 patients with mental retardation by BAC array CGH, identifying sixteen pathogenic rearrangements, including four patients with de novo microdeletions of 17q21.31. Using oligonucleotide arrays we refined the breakpoints of this microdeletion, defining a 478 kb critical region containing six genes that were deleted in all four cases. The breakpoints of this deletion, and of four other pathogenic rearrangements in 1q21.1, 15q13, 15q24 and 17q12 were mapped to flanking segmental duplications, suggesting that these are also sites of recurrent rearrangement. In common with the 17q21.31 deletion, these breakpoint regions are also sites of copy number polymorphism in controls, indicating that these may be inherently unstable genomic regions.
