  • Publication number: 20180334726
    Abstract: We determined the sequence of ATRX and DAXX in 447 cancers from various sites. We found mutations most commonly in pediatric glioblastoma multiformae (GBM) (11.1%), adult GBM (6.5%), oligodendrogliomas (7.7%) and medulloblastomas (1.5%); and showed that Alternative Lengthening of Telomeres (ALT), a telomerase-independent telomere maintenance mechanism found in cancers that have not activated telomerase, perfectly correlated with somatic mutations of either gene. In contrast, neuroblastomas, and adenocarcinomas of the ovary, breast, and pancreas were negative for mutations in ATRX and DAXX. Alterations in ATRX or DAXX define a specific molecular pathway that is closely associated with an alternative telomere maintenance function in human cancers.

  • Publication number: 20180258490
    Abstract: A diagnostic test for ovarian cysts is based on the detection of mutations characteristic of the most common neoplasms giving rise to these lesions. With this test, tumor-specific mutations were detected in the cyst fluids of 19 of 24 (79%) borderline tumors and 28 of 31 (90%) malignant ovarian cancers. In contrast, we detected no mutations in the cyst fluids from 10 non-neoplastic cysts and 12 benign tumors. When categorized by the need for exploratory surgery (i.e., presence of a borderline tumor or malignant cancer), the sensitivity of this test was 85% and the specificity was 100%. These tests could inform the diagnosis of ovarian cysts and improve the clinical management of the large number of women with these lesions.

  • Publication number: 20180230550
    Abstract: Clinical management of human cancer is dependent on the accurate monitoring of residual and recurrent tumors. We have developed a method, called personalized analysis of rearranged ends (PARE), which can identify translocations in solid tumors. Analysis of four colorectal and two breast cancers revealed an average of nine rearranged sequences (range 4 to 15) per tumor. Polymerase chain reaction with primers spanning the breakpoints were able to detect mutant DNA molecules present at levels lower than 0.001% and readily identified mutated circulating DNA in patient plasma samples. This approach provides an exquisitely sensitive and broadly applicable approach for the development of personalized biomarkers to enhance the clinical management of cancer patients.

  • Publication number: 20180171413
    Abstract: We queried DNA from saliva or plasma of 93 HNSCC patients, searching for somatic mutations or human papillomavirus genes, collectively referred to as tumor DNA. When both plasma and saliva were tested, tumor DNA was detected in 96% (95% CI, 84% to 99%) of 47 patients. The fractions of patients with detectable tumor DNA in early- and late-stage disease were 100% (n=10) and 95% (n=37), respectively. Saliva is preferentially enriched for tumor DNA from the oral cavity, whereas plasma is preferentially enriched for tumor DNA from the other sites. Tumor DNA in the saliva and plasma is a valuable biomarker for detection of HNSCC.

  • Publication number: 20180143427
    Abstract: An optical projection system provides part of a display system that presents a displayed virtual image at a predetermined distance in front of a viewing position. Said display system comprises a projection system and a primary reflecting optic that deflects an off-axis incoming optical signal from the projection system toward the viewing position. Said projection system is arranged to provide an adapted output image signal that compensates for optical aberration effects introduced by the reflecting optic to ensure provision of a reduced aberration display image to the viewing position, and where the reflecting optic comprises a grating structure.

  • Patent number: 9976184
    Abstract: To help reveal the pathogenesis of these lesions, we purified the DNA from Intraductal Papillary Mucinous Neoplasm (IPMN) cyst fluids from 19 patients and searched for mutations in 169 genes commonly altered in human cancers. We identified recurrent mutations at codon 201 of GNAS. We found that GNAS mutations were present in 66% of IPMNs and that either KRAS or GNAS mutations could be identified in 96%. In eight cases, we could investigate invasive adenocarcinomas that developed in association with IPMNs containing GNAS mutations. In seven of these eight cases, the GNAS mutations present in the IPMNs were also found in the invasive lesion. GNAS mutations were not found in other types of cystic neoplasms of the pancreas or in invasive adenocarcinomas not associated with IPMNs. These data suggest that GNAS mutations can inform the diagnosis and management of patients with cystic pancreatic lesions.

  • Publication number: 20180135044
    Abstract: The present disclosure involves ctDNA assays that interrogate many regions from a single sample with high precision and accuracy, while evaluating multiple forms of cancer-related genomic alterations including sequence mutations and structural alterations. The disclosure provides simplified yet robust methods that achieve high sensitivity and specificity by analyzing cancer genes using a limited pool of non-unique barcodes in combination with endogenous barcodes. Samples are captured and sequenced using high coverage next-generation sequencing to allow tumor-specific somatic mutations, amplifications, and translocations to be identified.

  • Publication number: 20180119230
    Abstract: Increased sensitivity and specificity of characterizing patient-specific variations as mutations that are indicative of a cancer or other disease by identifying patient-specific tumor mutations by comparing tumor and normal sequence reads from the patient and filtering for mutations that are unique to the tumor. By comparing tumor sequence to a normal sequence from the same patient, false-positive mutation calls are minimized in the analysis.

  • Publication number: 20180086832
    Abstract: Mutant epitopes encoded by cancer genes are virtually always located in the interior of cells, making them invisible to conventional antibodies. We generated single chain variable fragments (scFvs) specific for mutant peptides presented on the cell surface by human leukocyte antigen (HLA) molecules. These scFvs can be converted to full-length antibodies, termed MANAbodies, targeting “Mutation Associated Neo-Antigens” bound to HLA. A phage display library representing a highly diverse array of single-chain variable fragment sequences was first designed and constructed. A competitive selection protocol was then used to identify clones specific for peptides bound to pre-defined HLA types. In this way, we obtained scFvs, including one specific for a peptide encoded by a common KRAS mutant and another by a common EGFR mutant. Molecules targeting MANA can be developed that specifically react with mutant peptide-HLA complexes even when these peptides differ by only one amino acid from the normal, wild-type form.
