[EX Q]: The present study investigated how parents and peers interact in promoting or delaying Dutch adolescents' sexual initiation and intention and focused specifically on parents as moderators of peer influence.", "Using a longitudinal design, two waves of online questionnaire data were collected among 900 Dutch adolescents (M = 13.8 years at T1), who were sexually inexperienced at baseline. At T1, participants reported on three types of perceived sexual peer norms: friends' sexual behaviors (descriptive norms), friends' sexual attitudes (injunctive norms), and experienced peer pressure to have sex. They also rated two parenting aspects at T1: the general quality of their relationship with parents and the frequency of sexuality-specific communication with their parents. Six months later, the participants reported on their experience with different sexual behaviors ranging from naked touching or caressing to intercourse and their intention to have sex in the next school year.", "Relationship quality with parents was significantly associated with both outcomes, with a higher relationship quality predicting smaller odds of sexual initiation and less intention to have sex. Two significant interaction effects showed that frequent sexual communication with parents significantly reduced the effects of sexually active friends and experienced peer pressure on adolescents' intention to have sex.

[EX Q]: Syndromic forms of osteosarcoma (OS) account for less than 10% of all recorded cases of this malignancy. An individual OS predisposition is also possible by the inheritance of low penetrance alleles of tumor susceptibility genes, usually without evidence of a syndromic condition. Genetic variants involved in such a non-syndromic form of tumor predisposition are difficult to identify, given the low incidence of osteosarcoma cases and the genetic heterogeneity of patients. We recently mapped a major OS susceptibility QTL to mouse chromosome 14 by comparing alpha-radiation induced osteosarcoma in mouse strains which differ in their tumor susceptibility.', 'Tumor-specific allelic losses in murine osteosacoma were mapped along chromosome 14 using microsatellite markers and SNP allelotyping. Candidate gene search in the mapped interval was refined using PosMed data mining and mRNA expression analysis in normal osteoblasts. A strain-specific promoter variant in Rb1 was tested for its influence on mRNA expression using reporter assay.', 'A common Rb1 allele derived from the BALB/cHeNhg strain was identified as the major determinant of radiation-induced OS risk at this locus. Increased OS-risk is linked with a hexanucleotide deletion in the promoter region which is predicted to change WT1 and SP1 transcription factor-binding sites. Both in-vitro reporter and in-vivo expression assays confirmed an approx. 1.5 fold reduced gene expression by this promoter variant. Concordantly, the 50% reduction in Rb1 expression in mice bearing a conditional hemizygous Rb1 deletion causes a significant rise of OS incidence following alpha-irradiation.

[EX Q]: Fruiting body lectins have been proposed to act as effector proteins in the defense of fungi against parasites and predators. The Marasmius oreades agglutinin (MOA) is a lectin from the fairy ring mushroom with specificity for Galα1-3Gal containing carbohydrates. This lectin is composed of an N-terminal carbohydrate-binding domain and a C-terminal dimerization domain. The dimerization domain of MOA shows in addition calcium-dependent cysteine protease activity, similar to the calpain family.', 'Cell detachment assay, cell viability assay, immunofluorescence, live cell imaging and Western blot using MDCKII cell line.', 'In this study, we demonstrate in MDCKII cells that after internalization, MOA protease activity induces profound physiological cellular responses, like cytoskeleton rearrangement, cell detachment and cell death. These changes are preceded by a decrease in FAK phosphorylation and an internalization and degradation of β1-integrin, consistent with a disruption of integrin-dependent cell adhesion signaling. Once internalized, MOA accumulates in late endosomal compartments.
