Cell death is a common feature of neural development in all vertebrates. The bcl-2 proto-oncogene has been shown to protect a variety of cell types from programmed cell death. We have examined the distribution of bcl-2 protein in the developing and adult nervous systems. bcl-2 protein is widespread during embryonic development. Proliferating neuroepithelial cells of ventricular zones as well as...
buckwheat rutin has been found to be able to inhibit angiotensin ii (angii) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. in this study, myocardial hypertrophy model was made by adding angii to the medium of cardiac myocytes of neonatal rats, meanwhile, different concentrations of buckwheat rutin were applied to observe their effects. intrac...
BACKGROUND Proto-oncogene c-erbB-2 is located in chromosome 17 region q21 and codifies a 185 Kd protein, with tyrosine kinase activity. The amplification of this gene is associated with relapse and lower survival in breast cancer. Overexpression of this gene can be detected by immunohistochemistry (IHC). However, fluorescence in situ hybridization (FISH) and chromogenic in situ hybridization (C...
Buckwheat rutin has been found to be able to inhibit angiotensin II (AngII) - induced hypertrophy in cultured neonatal rat cardiomyocytes, but the mechanism remains uncertain. In this study, myocardial hypertrophy model was made by adding AngII to the medium of cardiac myocytes of neonatal rats, meanwhile, different concentrations of buckwheat rutin were applied to observe their effects.

OBJECTIVE B-cell-lymphoma-2 (Bcl-2) is a proto-oncogene that plays an important role in the regulation of apoptosis and cell survival. However, there are much conflicting data in the literature concerning the association between Bcl-2 and prognosis in non-small-cell lung cancer (NSCLC). There is little in the way of meta-analysis focused on Bcl-2 and its effect on NSCLC prognosis. This study wa...
A new transgenic mouse has been generated in which the proto-oncogene BCL-2 is ubiquitously overexpressed. H2K-BCL-2 transgenic mice overexpress BCL-2 in all cells of the hematolymphoid system and have been used to assess the role of BCL-2 in protecting cells of the hematolymphoid system from the consequences of ionizing radiation. We have expanded on previous studies that have demonstrated pro...
The c-kit proto-oncogene encodes a receptor tyrosine kinase that is thought to play an important role in hematopoiesis. In a series of human acute myeloblastic leukemia (AML), the expression of the c-kit proto-oncogene and its product was studied by means of Northern blot and immunoblot analyses. The c-kit mRNA was expressed in 20 of 25 cases of AML, and in those cases the product of the c-kit ...
The BCL-2 proto-oncogene encodes a mitochondrial protein that blocks programmed cell death. High amounts of bcl-2 protein are found not only in lymphoid malignancies, but also in normal tissues characterized by apoptotic cell death, including bone marrow. Using a monoclonal antibody to bcl-2 protein, we analyzed 82 samples of newly diagnosed acute myeloid leukemia. The number of bcl-2+ cells in...
The interleukin-2 (IL-2) receptor (IL-2R) is composed of three subunits. Of these, IL-2Ra is required for high-affinity IL-2 binding, while IL-2R beta and IL-2R gamma(c) are required for the transduction of IL-2-generated signals. Signals transduced via the S region of the IL-2R beta (amino acids 267-322) in BAF/3 cells activate the phosphatidylinositol 3-kinase (PI3-kinase) and induce the expr...
