Tumor cells in hypoxic areas of solid tumors are resistant to conventional chemotherapy and radiotherapy and thus are obstacles of cancer therapy. We report here the feasibility of applying hypoxia-regulated expression of diphtheria toxin A (DT-A) for killing hypoxic tumor cells. The expression
In genetically-modified Lmx1b(f/f/p) mice, selective deletion of LMX1B in Pet-1 expressing cells leads to failure of embryonic development of serotonin (5-HT) neurons. As adults, these mice have a decreased hypercapnic ventilatory response and abnormal thermoregulation. This mouse model has been
Hypoxia induces survival signals in hepatocellular carcinoma (HCC). Hypoxia and retinoic acid (RA) may also induce interleukin-2 (IL-2) receptor expression, and thus we evaluated if RA and IL-2 receptor-targeted therapy are indicated in hypoxic HCCs. RA induced IL-2 receptor expression (R alpha, R
Pulmonary arterial hypertension is a deadly disease of the pulmonary vasculature for which no disease-modifying therapies exist. Small-vessel stiffening and remodeling are fundamental pathological features of pulmonary arterial hypertension that occur early and drive further Hypoxia plays an important role in pathogenesis of infectious diseases. Therefore, its correction is an essential factor in pathogenetic antibacterial treatment. Hyperbaric oxygenation (HBO) as a leading method in current antihypoxic therapy was studied in combined medication for typhoid,
OBJECTIVE
This was a prospective, controlled, multicenter study to investigate the relationship between Bordetella pertussis infections and sudden unexpected deaths among German infants.
METHODS
Between 1995 and 1997, all infants who died at 7 to 365 days of age and for whom autopsies were performed
Chronic glomerular injury is associated with eventual development of tubulointerstitial fibrosis. Here we aimed to assess whether, and how, mild chronic tubulointerstitial injury affects glomeruli. For this, we generated mice expressing different toxin receptors, one on their proximal tubular
Immersion of tissue slices of liver or of kidney in buffered Krebs-Ringer solution at 38 degrees , with oxygenation, gives opportunity for the study of water exchange during 3 hours following removal of the tissue from the body. Under these conditions a wide variety of physical and chemical agents
OBJECTIVE
Hypoxia is a cause for resistance to cancer therapies. Molecularly targeted recombinant cytotoxins have shown clinical efficacy in the treatment of patients with primary brain tumors, glioblastoma multiforme, but it is not known whether hypoxia influences their antitumor effect.
METHODS
We
An aberrant oxygen environment at birth increases the severity of respiratory viral infections later in life through poorly understood mechanisms. Here, we show that alveolar epithelial cell (AEC) 2 cells (AEC2s), progenitors for AEC1 cells, are depleted in adult mice exposed to neonatal hypoxia or
