  The most important cytotoxic lesion formed by the nitrogen mustards is generally considered to be the DNA–DNA interstrand cross-link 12, 13. DNA–DNA interstrand cross-links are thought to exert their cytotoxic effects by inhibiting DNA duplex strand separation, progression of the inhibitor of catal

  2019-12-02

  

  Cancer has been linked to both genetic and epigenetic changes. Epigenetic modifications, mainly DNA methylation at CpG dinucleotides, affect the regulation of gene transcription without altering the gene\'s sequence. Short sequences rich in CpG dinucleotides (i.e., CpG islands) are often found in th

  Introduction The inflammation process involves sequential activation of signaling molecules, pro-inflammatory mediators, such as prostaglandins, leukotrienes, and oxygen free radicals [1]. Two cyclooxygenases Methylprednisolone australia were responsible for activation of the production of prostag

  Finally, considering the encouraging inhibitory and selectivity properties of compound and against isolated CK1δ, we have also acquired a very preliminary cytotoxicity profile on human ovarian carcinoma cell line (2008) and on its cisplatin-resistant clone (C13). Results showed that after 48h of exp

  2019-12-02

  

  Upon Edn ligand binding, endothelin receptors can induce a variety of intracellular signaling cascades leading to diverse cellular responses such as contraction in the case of smooth muscle cells, or cell growth and mitogenesis. Ednrs are expressed in a variety of cell types and tissues, for example

  Mechanisms of acquired resistance to 1st and 2nd generation EGFR inhibitors After treatment with first or second generation EGFR TKIs, virtually all patients after approximately 12 months develop acquired resistance (AR). Different mechanisms of AR to EGFR TKIs have been reported to date and may

  It has been reported that CysLT2 receptors negatively regulate CysLT1 receptor-mediated response in allergic airway inflammation in mice. Knockdown of CysLT2 receptors augmented CysLT1 receptor-mediated mast cell proliferation [31] and eosinophilic airway inflammation induced by antigen challenge in

  It has previously been shown that human melanocytes are responsive to a multiplicity of hormonal triggers [10], particularly to pituitary or ovarian hormones [11]. Studies concerning the effects of Ki16425 on human melanocytes led to inconsistent data [12], [13]. Im et al. [14] reported that the re

  Here, we report for the first time that EphB4 contains two NLS sequences and localises to the nucleus. This is mediated via an importin-α pathway and we show that EphB4 could potentially have a direct role in gene regulation. These data provide new insight into Eph receptor localisation and action a

  Introduction Hematopoietic stem ACSF and leukemic stem cells (HSCs and LSCs, respectively) both have a capacity of self-renewal. Whereas HSCs give rise to all blood lineages during lifetime hematopoiesis, LSCs are responsible for the initiation and propagation of leukemia, as well as drug resist

  Contrary to the downregulation of S1PR family GPCRs, CLL cells have increased mRNA expression of the lysophosphatidic rapamycin buy (LPA) family receptors LPAR1, LPAR3 and LPAR4 compared to normal B cells [47]. Increased LPAR1 mRNA has been shown to be associated with more aggressive disease [47] an

  Besides chemopreventive effects against oxidative DNA damage we evaluated the protective effects of the three Hypericum sp. and isolated compounds against alkylating DNA damage induced by MMS in HT29 cells. Human exposure to alkylating agents, from different sources, occurs in a continuous way and i

  Perturbations in notch signaling are known to induce apoptosis. Our results show that a fraction of the DT40YB-1b+/− cells, in addition to becoming tetraploids, undergo apoptotic cell death. Similar observations linking polyploidy and apoptosis have been made in the past [23], [30], [31], [32], [33
