Diversity in robustness of Lactococcus lactis strains during heat stress, oxidative stress, and spray drying stress

Dijkstra, Annereinou R; Setyawati, Meily C; Bayjanov, Jumamurat R; Alkema, Wynand (Data Science For Life Science & Health); van Hijum, Sacha A F T; Bron, Peter A; Hugenholtz, Jeroen

In this study we tested 39 Lactococcus lactis strains isolated from diverse habitats for their robustness under heat and oxidative stress, demonstrating high diversity in survival (up to 4 log units). Strains with an L. lactis subsp. lactis phenotype generally displayed more-robust phenotypes than strains …

Prednisolone induces the Wnt signalling pathway in 3T3-L1 adipocytes

Fleuren, Wilco W M; Linssen, Margot M L; Toonen, Erik J M; van der Zon, Gerard C M; Guigas, Bruno; de Vlieg, Jacob; Dokter, Wim H A; Ouwens, D Margriet; Alkema, Wynand (Data Science For Life Science & Health)

Synthetic glucocorticoids are potent anti-inflammatory drugs but show dose-dependent metabolic side effects such as the development of insulin resistance and obesity. The precise mechanisms involved in these glucocorticoid-induced side effects, and especially the participation of adipose tissue in this …

Identification of new biomarker candidates for glucocorticoid induced insulin resistance using literature mining

Fleuren, Wilco WM; Toonen, Erik JM; Verhoeven, Stefan; Frijters, Raoul; Hulsen, Tim; Rullmann, Ton; van Schaik, René; de Vlieg, Jacob; Alkema, Wynand (Data Science For Life Science & Health)

Background: Glucocorticoids are potent anti-inflammatory agents used for the treatment of diseases such as rheumatoid arthritis, asthma, inflammatory bowel disease and psoriasis. Unfortunately, usage is limited because of metabolic side-effects, e.g. insulin resistance, glucose intolerance and diabetes. …

van Lierop, Marie-José C; Alkema, Wynand (Data Science For Life Science & Health); Laskewitz, Anke J; Dijkema, Rein; van der Maaden, Hans M; Smit, Martin J; Plate, Ralf; Conti, Paolo G M; Jans, Christan G J M; Timmers, C Marco; van Boeckel, Constant A A; Lusher, Scott J; McGuire, Ross; van Schaik, Rene C; de Vlieg, Jacob; Smeets, Ruben L; Hofstra, Claudia L; Boots, Annemieke M H; van Duin, Marcel; Ingelse, Benno A; Schoonen, Willem G E J; Grefhorst, Aldo; van Dijk, Theo H; Kuipers, Folkert; Dokter, Wim H A

Glucocorticoids (GCs) such as prednisolone are potent immunosuppressive drugs but suffer from severe adverse effects, including the induction of insulin resistance. Therefore, development of so-called Selective Glucocorticoid Receptor Modulators (SGRM) is highly desirable. Here we describe a non-steroidal …

Molecular pathway profiling of T lymphocyte signal transduction pathways; Th1 and Th2 genomic fingerprints are defined by TCR and CD28-mediated signaling

Smeets, Ruben L; Fleuren, Wilco W M; He, Xuehui; Vink, Paul M; Wijnands, Frank; Gorecka, Monika; Klop, Henri; Bauerschmidt, Sussane; Garritsen, Anja; Koenen, Hans J P M; Joosten, Irma; Boots, Annemieke M H; Alkema, Wynand (Data Science For Life Science & Health)

BACKGROUND: T lymphocytes are orchestrators of adaptive immunity. Naïve T cells may differentiate into Th1, Th2, Th17 or iTreg phenotypes, depending on environmental co-stimulatory signals. To identify genes and pathways involved in differentiation of Jurkat T cells towards Th1 and Th2 subtypes we performed …

Prednisolone-induced beta cell dysfunction is associated with impaired endoplasmic reticulum homeostasis in INS-1E cells

Linssen, Margot M L; van Raalte, Daniel H; Toonen, Erik J M; Alkema, Wynand (Data Science For Life Science & Health); van der Zon, Gerard C; Dokter, Wim H; Diamant, Michaela; Guigas, Bruno; Ouwens, D Margriet

Glucocorticoids (GCs), such as prednisolone (PRED), are widely prescribed anti-inflammatory drugs, but their use may induce glucose intolerance and diabetes. GC-induced beta cell dysfunction contributes to these diabetogenic effects through mechanisms that remain to be elucidated. In this study, we hypothesized …

Background: G-protein coupled receptors (GPCRs) are involved in many different physiological processes and their function can be modulated by small molecules which bind in the transmembrane (TM) domain. Because of their structural and sequence conservation, the TM domains are often used in bioinformatics …
