DECORIN EFFECTS ON PROTEOMIC PROFILING OF BREAST CANCER CELLS: AN UPDATED STUDY
2015
The malignant carcinomas are characterized by several capabilities acquired by the neoplastic cells, among which the ability to invade the extracellular matrix (ECM) and to establish a crosstalk with several ECM components. Under this respect, the extracellular microenvironment is an entity extraordinarily rich of information with opposite signals. Our group has long undertaken the study of the effects of ECM molecules on the behavior of cancer cells in vitro. Among the studied molecules, the decorin was found to exert a non-permissive effect on the growth and motility of the transfected tumor cells. The decorin, belongs to the family of small leucine-rich proteoglycans (SLRP) and is involv…
Analyses of the TRACE V5 capability for the simulation of natural circulation and primary/containment coupling in BDBA condition typical of the MASLWR
2014
In the short term period the use of advanced Small Modular Reactor (SMR) is one of the most promising options for the deployment of nuclear technology. The validation and assessment of the best estimate thermal hydraulic system code TRACE against SMR thermal hydraulic phenomena is a novel effort. In this framework the use of the natural circulation database developed at the OSU-MASLWR test facility, simulating the MASLWR reactor prototype, is of interest for analyses of the TRACE code capability in predicting natural circulation and primary/containment coupled behavior in SMR. The target of this paper is to analyze the TRACE V5 capability for the simulation of natural circulation phenomena,…
Discovery and validation of small-molecule heat-shock protein 90 inhibitors through multimodality molecular imaging in living subjects.
2012
Up-regulation of the folding machinery of the heat-shock protein 90 (Hsp90) chaperone protein is crucial for cancer progression. The two Hsp90 isoforms (α and β) play different roles in response to chemotherapy. To identify isoform-selective inhibitors of Hsp90(α/β)/cochaperone p23 interactions, we developed a dual-luciferase (Renilla and Firefly) reporter system for high-throughput screening (HTS) and monitoring the efficacy of Hsp90 inhibitors in cell culture and live mice. HTS of a 30,176 small-molecule chemical library in cell culture identified a compound, N -(5-methylisoxazol-3-yl)-2-[4-(thiophen-2-yl)-6-(trifluoromethyl)pyrimidin-2-ylthio]acetamide (CP9), that binds to Hsp90(α/β) an…
Profilin1 regulates sternum development and endochondral bone formation.
2012
Bone development is a dynamic process that requires cell motility and morphological adaptation under the control of actin cytoskeleton. This actin cytoskeleton system is regulated by critical modulators including actin-binding proteins. Among them, profilin1 (Pfn1) is a key player to control actin fiber structure, and it is involved in a number of cellular activities such as migration. During the early phase of body development, skeletal stem cells and osteoblastic progenitor cells migrate to form initial rudiments for future skeletons. During this migration, these cells extend their process based on actin cytoskeletal rearrangement to locate themselves in an appropriate location within mic…

Tietoturvapolitiikan kehittäminen Pohjois-Pohjanmaan sairaanhoitopiirissä : Siponen & Puhakainen tietoturvapolitiikan kehittämismallin mukaisesti
2015
Tämän tutkimuksen tarkoituksena on selvittää, kuinka Siposen ja Puhakaisen tietoturvapolitiikan kehittämismallia toteutetaan ja kehitetään käytännössä. Se koostuu neljästä lähtökohdasta. Kirjallisuudesta ei löydy tietoturvapolitiikkaa, joka olisi toteutettu tämän mallin mukaisesti. Lisäksi tutkimuksessa selvitetään mallin soveltuvuutta Pohjois-Pohjanmaan sairaanhoitopiirissä (PPSHP). Tutkimus toteutettiin laadullisena toimintatutkimuksena, joka koostui viidestä vaiheesta: määrittäminen, suunnittelu, toteutus, arviointi sekä tarkentaminen ja oppiminen. Tutkimustietoaineisto kerättiin haastatteluiden avulla (PPSHP:n tietoturvasta ja tietosuojasta vastaavia henkilöitä), tutkimalla PPSHP:n stra…
Elucidating the aryl hydrocarbon receptor antagonism from a chemical-structural perspective.
2020
The aryl hydrocarbon receptor (AhR) plays an important role in several biological processes such as reproduction, immunity and homoeostasis. However, little is known on the chemical-structural and physicochemical features that influence the activity of AhR antagonistic modulators. In the present report, in vitro AhR antagonistic activity evaluations, based on a chemical-activated luciferase gene expression (AhR-CALUX) bioassay, and an extensive literature review were performed with the aim of constructing a structurally diverse database of contaminants and potentially toxic chemicals. Subsequently, QSAR models based on Linear Discriminant Analysis and Logistic Regression, as well as two tox…
The demand for IPR services - to use or not to use a professional representative
2021
We analysed the use of professional representative services and related outcomes in patent, utility model, design right and trademark filings. We found that: 1) there is a positive association between the use of a professional representative and the likelihood of grant or registration; 2) the demand for professional intellectual property rights (IPR) services is heterogeneous between IPR types: applicants are most likely to hire professional representatives (IPR agents and attorneys) for patents, followed by utility models, design rights and trademarks; 3) individual applicants are less likely to use professional representatives compared to firm applicants. peerReviewed
IPR gender gaps: a first look at utility model, design right and trademark filings
2018
This study extends the analysis of the gender gap in patenting into design rights, utility model (UMs) and trademarks (TMs), which are complementary methods for protecting intellectual property. The analysis is descriptive and uses register data from the Finnish patent and registration office covering the years 1982–2013. A persistent gender gap is found for all intellectual property rights. The gap has narrowed over time for national patent, design right and TM filings but not for UM filings. It is found that, in comparison to men, women are relatively less often single inventors or designers and more often members of inventor or designer teams. peerReviewed
Chromatin-dependent regulation of RNA polymerases II and III activity throughout the transcription cycle
2015
The particular behaviour of eukaryotic RNA polymerases along different gene regions and amongst distinct gene functional groups is not totally understood. To cast light onto the alternative active or backtracking states of RNA polymerase II, we have quantitatively mapped active RNA polymerases at a high resolution following a new biotin-based genomic run-on (BioGRO) technique. Compared with conventional profiling with chromatin immunoprecipitation, the analysis of the BioGRO profiles in Saccharomyces cerevisiae shows that RNA polymerase II has unique activity profiles at both gene ends, which are highly dependent on positioned nucleosomes. This is the first demonstration of the in vivo infl…
