  Generally, glycines (and other small residues such as alanine) present in a helical GxxxG-motif that are facing the same side of the helix form a uniform surface that enables direct contact with a second helix. Crystal structures of multipass membrane proteins have demonstrated that GxxxG-motifs are

  Introduction Cholesterol plays a pivotal role as a constituent of biological membranes and as a precursor for vitamins, hormones and bile acids. Accordingly, its production, distribution, and elimination must be tightly regulated at the cellular and organismal level. Accordingly, dysregulated chole

  The combination of brequinar and 5-fluorouracil (5-FU) has been evaluated to assess whether brequinar-induced uridine depletion would improve 5-FU activity. In cells, 5-FU is metabolized into FdUMP and inhibits thymidylate synthetase, which catalyzes the formation of thymidine monophosphate from deo

  The in vivo IC (0.0003μM) in the adipose tissue assay is in very good agreement with the in vitro IC (0.0005μM), and it is larger than the one measured in the OLTT assay (0.00005μM) for this compound. These differences in in vivo IC between OLTT and TAG synthesis are expected as we used free Verapam

  For radiochemotherapy, it is well known that mitotic cell death and apoptosis present the major cell death modes. More recently, autophagy-dependent cell death has been described to occur upon radiochemotherapy (Daido et al., 2005, Song et al., 2017). This form of regulated cell death depends on com

  In the present study, we used a new luminescent method to measure CYP activity with Luciferin-ME as a substrate which is used for wide ranges of mammalian CYPs, including CYP1A2, CYP2C8, CYP2C9, CYP2J2, CYP4A11, and CYP4F3B. As a result, no significant modulations of CYP activities in B[a]P exposure

  Tumor-associated macrophages (TAMs)—one of the limiting factors in anti-tumor immunity—are associated with the poor clinical outcome in most carcinomas, owing to their potential to promote angiogenesis and local invasion, increase the metastasis of tumor cells, and inhibit the anti-tumor immunity.11

  Besides the enhanced expression of costimulatory and adhesion proteins, also the expression of the CD83 surface molecule is strongly enhanced during DC maturation (Banchereau and Steinman 1998; Banchereau et al. 2000). In fact, CD83 is a major cell surface marker for fully mature DC, as it can not b

  The recombinant Scl2 collagen system has shown capability as a biomaterial as well because of its adaptability and scalability. Scl2 was functionalized to crosslink into a hydrogel without disrupting its triple helix [130]. The Scl2–hydrogel crosslinking also did not disrupt cell adhesion and integr

  Significance Ubl post-translational modifications are potential targets for developing novel therapeutics for life-threatening diseases, such as c-Myc- and KRas-driven cancers that lack targeted therapy. However, only a few drugs are available to target these modifications. This lack of drugs hig

  Ultrasonic pretreatment of substrates Substrate pretreatment is widely used in the biofuel, textile and food industries since the substrates are always difficult to degrade. During some enzymatic hydrolysis reactions, the protective layer of the substrate impedes the reaction. Ultrasonic treatmen
