bcl-2, bax, bcl-XL, and bcl-XS expression in normal and neoplastic ovarian tissues.
The bcl-2 family of proteins includes some important regulators of apoptosis. Among these, bcl-2 and bcl-xL prevent cells from entering apoptosis, whereas bax and bcl-xS can induce cell death. Alterations in the control of this process can lead to a decrease in cell death, thus contributing to neoplastic growth. Diminished susceptibility to chemotherapy has also been attributed, in in vitro sys...
متن کاملExpression of Bcl-2 and Bcl-2-Ig fusion transcripts in normal and neoplastic cells.
We examined the expression of the Bcl-2 gene at chromosome segment 18q21, that is translocated into the Ig heavy chain gene locus in t(14;18) bearing lymphomas. Bcl-2, while B cell associated, is expressed in a variety of hematopoietic lineages including T cells. Bcl-2 mRNA levels are high during pre-B cell development, the time at which the t(14;18) translocation occurs, but are down regulated...
متن کاملInterleukin 6 gene expression in normal and neoplastic B cells.
In the present report we demonstrate that the IL-6 gene is expressed in anti-Ig-activated and neoplastic B cells. After activation with anti-Ig, splenic B cells rapidly expressed IL-6 mRNA with peak expression occurring at 4 h and declining rapidly thereafter. In an attempt to exclude that the IL-6 mRNA expression was in non-B cells, T cells and monocytes were extensively depleted. In this high...
متن کاملGSTA1 expression in normal, preneoplastic, and neoplastic human prostate tissue.
BACKGROUND Glutathione S-transferases (GSTs), inducible enzymes that catalyze the detoxification of reactive electrophiles and oxidants, protect against neoplastic transformation. Prostatic adenocarcinoma and high-grade prostatic intraepithelial neoplasia (HGPIN) fail to express GSTP1, a major class of GST. This failure of expression is associated with methlyation of the GSTP1 promoter, a somat...
