Opis:: We present the results of an exploratory analysis of hu‐ man attitudes toward the social robot Vector. The study was conducted on natural language data (2,635 com‐ ments) retrieved from Reddit and YouTube. We describe the tag‐set used and the (manual) annotation procedure. We present and compare attitude structures mined from Reddit and YouTube data. Two main findings are descri‐ bed and discussed: almost 20% of comments from both Reddit and YouTube consist of various manifestations of attitudes toward Vector (mainly attribution of autonomy and declaration of feelings toward Vector); Reddit and YouTube comments differ when it comes to revealed at‐ titude structure – the data source matters for attitudes studies.

Opis:: Receptors of the β1 integrin family are involved in many tumor-promoting activities. There are several approaches currently used to control integrin activity, and thus to potentially restrain tumor metastasis and angiogenesis. In this study, we compared inhibitory efficiencies of siRNA and DNAzymes against the β1 integrin subunit (DEβ1), in a mouse xenograft model. Both inhibitors were used under their most favorable conditions, in terms of concentrations, incubation time and lack of cytotoxic effects. Transfection of siRNAβ1 or DEβ1 remarkably inhibited the growth of both PC3 and HT29 colon cancer cells in vitro, and decreased their capability of initiating tumor formation in the mouse xenograft model. siRNAβ1 appeared to be slightly more efficient than DEβ1 when tested in vitro, however it was comparably less proficient in blocking the tumor growth in vivo. We conclude the DNAzyme, due to its greater resistance to degradation in extra- and intracellular compartments, to be a superior inhibitor of tumor growth in long lasting experiments in vivo when compared to siRNA, while the latter seems to be more efficient in blocking β1 expression during in vitro experiments using cell cultures.
