Abstract:
A method of preparing a species-specific phosphorylation site peptide array for a target organism comprising: a) selecting a plurality of known non-target organism (NTO) phosphorylation site sequences and cognate known NTO phosphorylation polypeptide sequences from one or more NTO, each of the known NTO phosphorylation site sequences comprising at least 5 residues and less than 30 residues; b) identifying a matching target organism (TO) phosphorylation site sequence and cognate TO phosphorylation polypeptide sequence for one or more of the known NTO phosphorylation site sequences; c) determining the matching TO phosphorylation site sequences that correspond to orthologue polypeptides of the cognate known NTO phosphorylation polypeptide sequences; d) selecting the matching TO phosphorylation site sequences determined to correspond to orthologue polypeptides for inclusion on the array; wherein the matching TO phosphorylation site sequences that correspond to orthologue polypeptides are determined by calculating, for each matching phosphorylation site sequence identified in b), a similarity value between the TO phosphorylation polypeptide sequence corresponding to the TO phosphorylation site sequence and a TO polypeptide sequence matching the cognate known NTO polypeptide sequence.
Abstract:
Rapid and specific detection of biological cells and biomolecules is important to biological assays across diverse fields including genomics, proteomics, diagnoses, and pathological studies. Microarrays and microfluidics increasingly dominate such detection techniques due to the ability to perform significant numbers of tests with limited sample volumes. A snap chip assembly is provided for the transfer of a microarray of reagents within semi-spherical liquid droplets on a transfer chip to a target assay microarray on an assay chip following assembly of the two chips and physical contact of the droplets with the target array. Reagents in nanolitre quantities are spotted on both chips and selectively transferred from liquid droplets on the transfer chip to the assay chip within the contact areas. Using the snap chip structure the inventors performed immunoassays with colocalization of capture and detection antibodies with 10 targets and bead-in-gel droplet microarrays with 9 targets in the low pg/ml regime.

Abstract:
Novel biomarkers and targets associated with ovarian cancer, particularly clear-cell carcinoma, endometrioid carcinoma, and uterine carcinoma, are disclosed. Mutations in genes encoding proteins that form part of the SWI/SNF chromatin remodelling protein complex, including ARID1A, or loss of expression of such proteins, including BAF250a, can be used to evaluate the likelihood endometriosis will progress or transform to cancer, to provide a prognosis for a patient with cancer, to assess whether conventional treatment is likely to be effective against a cancer, and/or in a synthetic lethal screen to identify novel targets and therapeutics for the treatment of cancer.
Abstract:
Purpose. The relationship between inherited genetic variations in 5α-reductase type 1 (SRD5A1) and type 2 (SRD5A2) genes and the risk of biochemical recurrence after radical prostatectomy (RP) in prostate cancer (PCa) remains a fairly unexplored area of research. Patients and Methods. We studied 526 men with organ-confined and locally advanced PCa with a median follow-up time of 7.4 years. We investigated the effects of allelic variants of SRD5A1 and SRD5A2 genes and haplotype-tagging single nucleotide polymorphisms (htSNPs; n=19) on recurrence-free survival after RP using Kaplan-Meier plots, the log-rank test, and Cox proportional hazard models. Results. Upon adjusting for known prognostic clinical and pathological factors, eight htSNPs were shown to be independent predictors of recurrence. The SRD5A1 rs 166050 polymorphism was associated with an increased recurrence risk of HR=1.83 (95% CI, 1.04-3.21; P=0.035), while the rs518673 in SRD5A1 was associated with a decreased risk (HR=0.59, 95% CI, 0.41-0.85; P=0.004). The SRD5A2 gene was strongly associated with the risk of relapse with six polymorphisms being positively associated with recurrence including the known SRD5A2 V89L (rs523349) (HR=2.14, 95% CI, 1.23-3.70; P=0.007) and a protective htSNP rs12470143 with a HR of 0.66, (95% CI, 0.46-0.95; P=0.023). By combining SRD5A1 (rs518673T) and SRD5A2 (rs 12470143 A), the protective effect was shown to be additive with the maximum protection conferred by 3 or 4 alleles (HR=0.33, 95% CI, 0.17-0.63; P=0.001). Conclusion. Germline polymorphisms in 5α-reductase genes are independent prognostic genetic biomarkers that predict PCa biochemical recurrence after radical prostatectomy and may represent useful molecular tools for a genotype-tailored clinical approach.
