WO previous workers have estimated the number of pairs of genes controlling Tthe response of the chicken to Rous sarcoma virus. PRINCE (1958) proposed (a) that a single pair of autosomal alleles controlled susceptibility and resistance of chorioallantoic membranes to Rous sarcoma virus and (b) that susceptibility (allele S) was dominant to resistance (s) . This proposal was based on the proport...
UNLABELLED ETHNOPHARMACOLOGICAL RELAVENCE: Physalis angulata is well-known in traditional Chinese medicine as a ingredient for various herbal formulation; also, it has been shown to exhibit anti-cancer and anti-inflammatory effects. In this study, the ability of P. angulata to inhibit tumor metastasis and angiogenesis was investigated. MATERIALS AND METHODS Anti-proliferative activity of ethy...
BACKGROUND Although agonistic autoantibodies against type-1 angiotensin-II receptor (AT1-AA) are frequently detected in women with preeclampsia, the clinical significance of AT1-AA in association with epithelial ovarian cancer (EOC) has not been identified. METHODS In an attempt to clarify this issue, we measured serum AT1-AA titer from EOC patients (n = 89) and healthy normal subjects (n = 5...
A new class of angiostatic steroids acts independently of previously identified steroid functions to inhibit angiogenesis when administered with heparin. Development of angiostatic steroids as therapeutic modulators of blood vessel growth would be greatly facilitated if their mode of action were thoroughly understood. However, the mechanism by which these steroids produce capillary regression i...
B: Basil is an herb that has been noted for its many health benefits, including the ability to fix one-sided headaches and so on. Angiogenesis, formation of new vessels from the primary vessels is involved in physiological and pathological. This process is essential for the proliferation of endothelial cells in the repair process. This study stimulatory effects of aqueous extract of Ocimum basi...
BACKGROUND Hypoxia-inducible factor-1 alpha (HIF-1α) maybe an important regulatory factor for angiogenesis of small cell lung cancer (SCLC). Our study aimed to investigate the effect of HIF-1α on angiogenic potential of SCLC including two points: One is the effect of HIF-1α on the angiogenesis of SCLC in vivo. The other is the regulation of angiogenic genes by HIF-1α in vitro and in vivo. MET...
During development, the chick embryo mobilizes the calcium it needs from two extraembryonic sources, first the yolk and then the eggshell. Since previous studies have strongly suggested that vitamins D and K may regulate chick embryonic calcium metabolism, we have examined here how these vitamins might be involved in regulating the calcium mobilization processes. We used as our experimental sys...
Epithelial-mesenchymal transition (EMT) is required for mesodermal differentiation during development. The zinc-finger transcription factor, Snail1, can trigger EMT and is sufficient to transcriptionally reprogram epithelial cells toward a mesenchymal phenotype during neoplasia and fibrosis. Whether Snail1 also regulates the behavior of terminally differentiated mesenchymal cells remains unexpl...
