FR900359, an inhibitor of guanine nucleotide dissociation, effectively blunts signaling of GTPase-deficient Gq: mechanism of action and relevance for treating Gq-driven cancers
(2019-08-01)
Uveal melanoma (UM), the most common cancer of the adult eye, is known to have poor prognosis. Over 50% of patients are likely to develop metastasis. In more than 80% of the cases UM is driven by an activating mutation in ...
Impact of ERK signaling and its spatial regulation on cisplatin sensitivity in ovarian cancer cells
(2019-11-08)
The efficiency of the anticancer drug cisplatin in ovarian cancer is often limited by the development of cisplatin resistance. Cisplatin activates a plethora of DNA damage-related signaling pathways, which regulate the ...
Platelet-immune cell interactions in inflammation and cancer
(2019-09-10)
Platelets are well-known for their role in hemostasis and only more recently, they have also been acknowledged for their immune regulatory roles. Despite being small sized and anucleated, they can respond to inflammatory ...
Mechanisms of epileptogenesis in animal models of developmental brain lesions
(2021-11-05)
Developmental brain lesions, including glioneuronal tumors (GNT) and malformations of cortical development (MCD), are among the most common causes for pharmaco-resistant epilepsy. Despite substantial differences, their ...
Characterization of VKORC1L1 with respect to VKORC1
(2019-07-10)
Vitamin K reduction is essential and catalyzed by two enzymes in vitro. Vitamin K 2,3-epoxide reductase complex subunit 1 (VKORC1) reduces vitamin K to sustain γ-carboxylation of vitamin K dependent (VKD) proteins. This ...
Compartmentalisation of cAMP in Brown Adipocytes
(2022-02-14)
The second messenger, 3',5'-cyclic adenosine monophosphate (cAMP) plays an important role in governing the function and differentiation of brown adipocytes. Upon the stimulation of Gs-coupled G protein-coupled ...
Vorkommen Antibiotika-resistenter Bakterien in der aquatischen Umwelt: Zusammenhänge zu dem Vorkommen antibiotisch wirkender Substanzen
(2022-01-05)
Ein Anstieg der Resistenzen bei gleichzeitiger Stagnation hinsichtlich der Ent-wicklung neuer Antibiotika ist vor allem für Infektionen mit Gram-negativen Bakte-rien kritisch. Die WHO spezifizierte bereits 2014 ...
Investigating 5-HT2A receptors - Development of a fluorescent 5HT2A receptor agonist and elucidation of the effects of St. John's wort extract STW3-IV, hyperforin and hyperoside on 5HT2A receptors
(2021-09-22)
Investigating 5-HT2A receptors - Development of a fluorescent 5HT2A receptor agonist and elucidation of the effects of St. John's wort extract STW3-IV, hyperforin and hyperoside on 5HT2A ...
Design, Entwicklung und Herstellung modifizierter gastroretentiver schwimmender Systeme auf Basis von schmelzextrudierten hohlen Zylindermatrices
(2020-04-15)
Die Entwicklung gastroretentiver Arzneiformen ist komplex, da neben der kontrollierten Freisetzung des Wirkstoffs zusätzlich die Verlängerung der Verweilzeit im Magen gewährleistet werden muss. Hierfür werden meist hydrophile ...
Evaluating onco-geriatric scores and medication risks to improve cancer care for older patients
(2020-03-19)
The cancer therapy of older patients is challenging, being more complex than the therapy of younger patients. Older cancer patients show a higher toxicity risk during therapy and drug-related problems are common. In order ...
