  2020-01-10

  

  Similar to EGFR, another receptor tyrosine kinase (RTK), fibroblast growth factor receptor 4 (FGFR4), is gaining attention in the lung cancer setting. The protein expression of this receptor has been recently associated with a negative impact on lung cancer prognosis, supporting the idea that FGFR4

  Two-photon microscopy experiments demonstrated that most contacts between GC B and Tfh cells are of short duration (about 2 min), and only about 4% of these contacts lead to the formation of stable conjugates (5 to 60 min) (Allen et al., 2007). Similarly, during extrinsic peptide stimulation, some r

  2020-01-09

  

  Oxysterols modulate the immune responses and as such could be effectors of the tumor environment: 25-OHC impairs IgA production in B-lymphocytes [26] and induces the secretion of the proinflammatory and angiogenic cytokine IL-8 [27], [28]. Of note, oxysterols (in particular 7α,25-OHC) are potent che

  Cysteine protease activities have been suggested to be important for Giardia’s pathogenesis [[11], [12], [13],16,18,19,21,28,29,35]. Recently several giardial CPs were shown to be released during host cell interactions [9,10]. The three major released CPs have recently been shown to be involved in t

  Trk receptors critically support the development and maintenance of the nervous system, , but their over-expression in various neural and non-neural neoplasms such as breast, pancreatic, lung and neuroendocrine tumors also confers aggressive phenotypes to tumor mecamylamine synthesis and correlate

  2020-01-09

  

  Expression of MGMT in human LY294002 can be switched off by enzymatic methylation of a cytosine residue in the MGMT promoter sequence. In this regard, both MGMT and the mismatch repair function MLH1 belong to a subset of DNA repair genes that are subjected to epigenetic control. In consequence, abo

  Although further experiments are needed to determine definitively whether D–ETB receptor heterodimers exist, for example, by using fluorescence resonance SR 8278 transfer analysis or co-immunoprecipitation of receptors, the results of the study by Zeng and colleagues appear to indicate that D–ETB r

  In Murray–Darling rainbowfish, confirming the expected in vivo effects of androgenic progestins could be achieved using short-term exposures and determining expression profiles for androgen-responsive genes, or in longer term exposures by monitoring fecundity or the development of male secondary sex

There are two mammalian EPAC isoforms, EPAC1 and EPAC2 1, 2 (Figure 1). Whereas EPAC1 displays a wide tissue distribution, the expression of EPAC2 is more restr

  The Czech Republic is a country with increasing CDI incidence (1.1 cases per 10,000 patient bed-days in 2008–4.4 cases in 2011–2012 and 6.2 cases per 10,000 patient bed-days in 2012–2013) (Bauer et al., 2011, Davies et al., 2014) and relatively high rates of antibiotic resistant C. difficile strains

  The strong adsorption of amines to the stationary phase of gas chromatography (GC) columns causes issues such as tailing, ghosting and low reproducibility [12], [13]. A common practice to overcome this problem is the chemical derivatisation of amines prior to GC analysis [14]. Comprehensive reviews
