Prophylaxis and treatment of inherited clotting disorder hemophilia A requires regular administration of factor VIII. Recombinant factor VIII, which is produced in CHO or BHK cells, is equivalent to the plasma-derived one and is prevalent in current clinical practice in developed countries. Development of a biosimilar recombinant FVIII requires the ...

Application of human adenovirus type 5 (Ad5) derived vectors for cancer gene therapy has been limited by the poor cell surface expression, on some tumor cell types, of the primary Ad5 receptor, the coxsackie-adenovirus-receptor (CAR), as well as the accumulation of Ad5 in the liver following interaction with blood coagulation ...

Carpospore output and development in the marine red alga Hydropuntia cornea J. Agardh. were increased by adding polyamines (PAs) (putrescine, spermidine and spermine) singly or in combinations at 10(-9), 10(-6) and 10(-3) M. Cell divisions after spore release and development of apical axis between 17 and 21 days characterized carpospore development. PAs ...

Hyaluronan is a crucial glycosaminoglycan of the vertebrate embryonic extracellular matrix able to influence cell behaviour, both by assembling the pericellular matrices and by activating signal transducing receptors such as CD44. We showed that the hyaluronan synthases, Has1 and Has2, and CD44 display a dynamic expression pattern during cranial neural ...

During early vertebrate development, the embryonic ectoderm becomes subdivided into neural, neural plate border (border) and epidermal regions. The nervous system is derived from the neural and border domains which, respectively, give rise to the central and peripheral nervous systems. To better understand the functional nervous system we need to ...

Huntington's disease (HD), caused by an expanded triplet repeat in the huntingtin (Htt) gene, results in extensive neuropathology, but study of the Htt gene in CNS development through gene knockout is problematic as the knockout leads to embryonic lethality in mice. Here, we report that the knockdown of Htt expression ...

Controversy persists regarding the role of Notch signaling in myelopoiesis. We have used genetic approaches, employing two Notch zebrafish mutants deadly seven (DES) and beamter (BEA) with disrupted function of notch1a and deltaC, respectively, and Notch1a morphants to analyze the development of leukocyte populations in embryonic and mature fish. Myelomonocytes ...

Goblet cell hyperplasia is a common feature of chronic obstructive pulmonary disease (COPD) airways, but the mechanisms that underlie this epithelial remodelling in COPD are not understood. Based on our previous finding of hypoxia-inducible factor-1α (HIF-1α) nuclear localization in large airways from patients with COPD, we investigated whether hypoxia-inducible signalling ...

Bronchiolar Clara cells are integral components of lung homeostasis, predominantly distributed in distal airways. In addition to the 16 kDa Clara cell protein, a major secretory product with anti-inflammatory effects, rat Clara cells express the glycan-binding protein galectin-3 and secrete it into the airways. Given the essential role of galectin-3 ...

In the developing cerebellum, proliferation of granular neuroprogenitor (GNP) cells lasts until the early postnatal stages when terminal maturation of the cerebellar cortex occurs. GNPs are considered cell targets for neoplastic transformation, and disturbances in cerebellar GNP cell proliferation may contribute to the development of pediatric medulloblastoma. At the molecular ...

The let-7 family of microRNAs (miRNAs) are known to act as tumor suppressors and down-regulated in lung cancer. Recently, the RNA-binding protein Lin-28 was demonstrated to inhibit biogenesis of let-7 miRNAs by blocking both Drosha- and Dicer-mediated cleavage and accelerating decay of let-7 precursors. We selected NCI-H446 lung small cell ...

microRNAs play an important roles in cell growth, differentiation, proliferation and apoptosis. They can function either as tumor suppressors or oncogenes. We found that the overexpression of miR-192 inhibited cell proliferation in A549, H460 and 95D cells, and inhibited tumorigenesis in a nude mouse model. Both caspase-7 and the PARP ...

A new reduced hydroxamate, 2,3-dihydrotrichostatin A, was created from trichostatin A by employing a recombinant strain of Streptomyces venezuelae as a microbial catalyst. Compared with trichostatin A, 2,3-dihydrotrichostatin A showed similar antifungal activity against Saccharomyces cerevisiae, but, interestingly, approximately twice the cytostatic activity against human small-cell lung cancer cells. The ...

Prior work has shown that transforming growth factor-β (TGF-β) can mediate transition of alveolar type II cells into mesenchymal cells in mice. Evidence this occurs in humans is limited to immunohistochemical studies colocalizing epithelial and mesenchymal proteins in sections of fibrotic lungs. To acquire further evidence that epithelial-to-mesenchymal transition occurs ...

Lung cancer is the leading cause of cancer death worldwide. The epidermal growth factor receptor (EGFR) represents the main target for non-small cell lung cancer (NSCLC) therapy, as its overexpression or constitutive activation contributes to malignancy and correlates with poor prognosis. Our previous work demonstrated that in epithelial cells β1 ...

It is established that cigarette smoke (CS) causes irreversible oxidations in lung epithelial cells, and can lead to their death. However, its impact on reversible and physiologically relevant redox-dependent protein modifications remains to be investigated. Glutathione is an important antioxidant against inhaled reactive oxygen species as a direct scavenger, but ...

It has been challenging to engineer lung adenocarcinoma models via oncogene-mediated transformation of primary cultured normal human cells. Although viral oncoprotein-mediated malignant transformation has been reported, xenografts derived from such transformed cells generally represent poorly differentiated cancers. Here, we demonstrate that the combined expression of multiple cellular factors induces malignant ...
