Epithelial ovarian cancer (EOC) is a deadly cancer, and its prognosis has not been changed significantly during several decades. To seek new therapeutic targets for EOC, we performed an in vivo dropout screen in human tumor xenografts using a pooled shRNA library targeting thousands of druggable genes. Then, in follow-up studies, we performed a second screen using a genome-wide CRISPR/Cas9 library. These screens identified 10 high-confidence drug targets that included well-known oncogenes such as ERBB2 and RAF1, and novel oncogenes, notably KPNB1, which we investigated further...

PURPOSE: We examined disparities in prognosis between patients with ovarian clear cell carcinoma (OCCC) and serous epithelial ovarian cancer (SOC). METHODS: We reviewed data from FIGO stage I-IV epithelial ovarian cancer patients who participated in 12 prospective randomized GOG protocols. Proportional hazards models were used to compare progression-free survival (PFS) and overall survival (OS) by cell type (clear cell versus serous). RESULTS: There were 10,803 patients enrolled, 9531 were eligible, evaluable and treated with platinum, of whom 544 (6%) had OCCC, 7054 (74%) had SOC, and 1933 (20%) had other histologies and are not included further...

There is broad agreement that genetic mutations occurring outside of the protein-coding regions play a key role in human disease. Despite this consensus, we are not yet capable of discerning which portions of non-coding sequence are important in the context of human disease. Here, we present Orion, an approach that detects regions of the non-coding genome that are depleted of variation, suggesting that the regions are intolerant of mutations and subject to purifying selection in the human lineage. We show that Orion is highly correlated with known intolerant regions as well as regions that harbor putatively pathogenic variation...

This phase-I/phase-II study evaluated panobinostat in combination with ifosfamide, carboplatin, etoposide (P-ICE) in relapsed/refractory classical Hodgkin lymphoma. During phase I, panobinostat was given daily on Monday/Wednesday/Friday starting one week prior to Cycle 1 (C1) of ICE and during two weeks of C1-2 of ICE (Schedule A). No DLT was observed at 30 mg. However, frequent (84%) grade-4 thrombocytopenia during second week prompted us to omit the second week of panobinostat 30 mg (Schedule B) for phase II, where this regimen was compared to ICE...

There are a limited number of methods to guide and confirm the placement of a peripherally-inserted central catheter (PICC) at the cavoatrial junction. The aim of this study was to design, test, and validate a dual wavelength, diode laser-based, single optical fiber instrument that would accurately confirm PICC tip location at the cavoatrial junction of an animal heart, in vivo. This was accomplished by inserting the optical fiber into a PICC and ratiometrically comparing simultaneous visible and near-infrared reflection intensities of venous and atrial tissues found near the cavoatrial junction...

The HIV/AIDS crisis continues in sub-Saharan Africa, where nearly 70% of infections are found. Despite recent efforts to supply antiretroviral therapy to those infected, most are not receiving medication and are forced to rely on self-management to remain healthy. In Kenya, many of those infected are women living in extreme poverty. This article presents the findings of research among poor women in Nairobi that examined the relationship between knowledge of a cultural model of self-managing HIV/AIDS, cultural consonance, and health...

Carbonaceous compounds are a significant component of fine particulate matter and haze in national parks and wilderness areas where visibility is protected, i.e., class I areas (CIAs). The Regional Haze Rule set the goal of returning visibility in CIAs on the most-anthropogenically-impaired days to natural by 2064. To achieve this goal, we need to understand contributions of natural and anthropogenic sources to the total fine particulate carbon (TC). A Lagrangian chemical transport model was used to simulate the 2006-2008 contributions from various source types to measured TC in CIAs and other rural lands...

PURPOSE: Protein phosphatase 2A (PP2A) is a family of serine/threonine phosphatases that regulate multiple cellular signalling pathways involved in proliferation, survival and apoptosis. PP2A inhibition occurs in many cancers and is considered a tumour suppressor. Deletion/downregulation of PP2A genes has been observed in breast tumours, but the functional role of PP2A subunit loss in breast cancer has not been investigated. METHODS: PP2A subunit expression was examined by immunohistochemistry in human breast tumours, and by qPCR and immunoblotting in breast cancer cell lines...
