  2020-07-21

  

  Programmed cellular death or apoptosis is a process genetically controlled that plays an important role in cellular homeostasis, being an important defense mechanism to remove cells that have been infected, damaged or mutated (Smith and Smith, 2012, Wlodkowic et al., 2011). Nevertheless, apoptosis s

  Introduction Excessive exposure to ultraviolet (UV) irradiation from the sun injures human skin, which might lead to premature aging and skin pathologies [1], [2]. Chronic exposure to UV (especially ultraviolet-B, UVB) irradiation could profoundly affect the skin epidermis, interfering with the ker

  2020-07-20

  

  Extracellular uridine can be transported across the cell membrane to enter the nucleotide salvage pathway. A colon cancer cell line supplemented with uridine was capable of growing normally in the presence of 1 μM brequinar (Peters et al., 1992). The supplemented uridine may be transported into the

  The identification of a gatekeeper Bradykinin acetate also suggests that alternative DDR2 inhibitors may be required to overcome acquired resistance. Additional DDR2 inhibitors that have been isolated include the recently identified alkaloid natural products discoipyrroles A-D and the chemotherapeut

  We further evaluated the functional relation between promoter regulation of the tumor suppressor genes and in fresh frozen, microdissected tumor tissue from 55 patient with clear cell renal carcinoma. In addition, normal-appearing tissue from the same patient taken distal of the tumor and later hi

  CXCR5 CXCR5 is a homeostatic chemokine receptor for lymphocytes and plays a critical role in the development of lymphoid organs as well as regulating the interaction between antigen presenting cells and lymphocytes (Cannons et al., 2012). It is one of the major chemokine receptors dictating norma

  2020-07-20

  

  Among prostaglandins (PG), PGD2 remained the most elusive species for a long time and was initially regarded as having negligible biological activity [1]. In 1974 its inhibitory effect on platelet aggregation was discovered by Smith et al. [2] and Mills & McFarlain [3], and both pressor and depresso

  2020-07-20

  

  Acknowledgments Casein kinases (CK) are serine/threonine-specific enzymes and can be divided two subtypes: casein kinase 1 (CK1) and casein kinase 2 (CK2). CK1 contains at least seven isoforms (α, β, γ1, γ2, γ3, δ and ε) expressed in eukaryotic organisms, CK1 is involved in various cellular pro

  FGF/ERK signaling has been implicated in epithelial-mesenchymal interactions in a wide range of tissues (Huh et al., 2015, Klein et al., 2006, Rice et al., 2004, Zhang et al., 2006, El Ramy et al., 2005, Volckaert and Langhe, 2015). During embryonic organogenesis and in adult organs, we often observ

  There is a considerable molecular genetic heterogeneity within ES/PNET. As mentioned above, either or can rearrange with in these gene fusions. Furthermore, for either gene fusion, additional heterogeneity stems from the location of the genomic breakpoints of the translocation, resulting in diffe

  Materials and methods Results Discussion COX-2-mediated production of PGE2 is involved in cell growth and metastasis of many cancers. Previous studies indicated that COX-2 was overexpressed in many cancer tissues and that PGE2 increased cancer cell growth, a process that could be suppressed

  Given that CE plays an essential role in schistosome invasion, its immunoreactivity and protective potential is of significant interest. The native form of SmCE was found to be poorly immunogenic in immunized mice. An earlier study found that sera from S. mansoni patients have shown the presence of

  Several DA receptors heteromers with a therapeutic potential have been described, including D1R/D3R (Fiorentini et al., 2010), but their roles remain to be established. Moreover, most studies on receptor heteromers in addiction focused on the striatum because of its key role in the pathology and its

  The first transcription factor (TF) known to interact with one of the cis-acting GAREs is GAMYB protein, the expression of which is induced by GA in the aleurone CGP 53353 of barley (HvGAMYB) (Gubler and Jacobsen, 1992). GAMYB is an important regulator of endosperm functions during seed development
