Allgemeine Beschreibung
Purified rabbit polyclonal antibody. Recognizes the ~28 kDa Bcl-x protein.
Recognizes the ~28 kDa Bcl-x protein in doxorubicin-treated MCF-7 cells.
bcl-x is a bcl-2-related gene that can function as a regulator of programmed cell death (apoptosis) independent of bcl-2. Alternative splicing results in two distinct bcl-x mRNAs, bcl-xL and bcl-xS. The larger mRNA gives rise to a protein product, bcl-xL, which is similar in size and predicted structure to bcl-2. bcl-x immunoreactivity has been detected in a wide variety of cell types and the protein is typically present in the cytosol in association with the mitochondrial periphery, a property shared with bcl-2. Of the two isoforms of bcl-x, the long (bcl-xL) is the most abundant mRNA species expressed in embryonic and adult tissues and most likely differs from bcl-2 in its regulatory activity on cell differentiation through controlled tissue specific expression. Like its homolog bcl-2, the mechanism and extent of bcl-x′s function are still increasing. bcl-xL has been shown to modify the cell′s response to oxidants as well as to participate in resistance to chemotherapeutic agents and radiation.

The in vivo patterns of bcl-X gene expression were assessed in human and mouse tissues using an immunohistochemical approach. Polyclonal antisera were raised against synthetic peptides corresponding to amino acids 46-66 and 61-79 of the human Bcl-X protein and were

Developing lymphocytes undergo extensive cell death during selection of the immune repertoire. We investigated the influence of bcl-xL, a member of the bcl-2 family of apoptosis regulatory genes, on apoptosis in a model system for negative selection in the B

Most examples of cell death in animals are controlled by a genetic program that is activated within the dying cell. The apoptotic process is further regulated by a set of genes that act as repressors of cell death. Of these

We report the isolation of bcl-x, a bcl-2-related gene that can function as a bcl-2-independent regulator of programmed cell death (apoptosis). Alternative splicing results in two distinct bcl-x mRNAs. The protein product of the larger mRNA, bcl-xL, is similar in

Acquired resistance to diverse chemotherapeutic agents has been associated with overexpression of the P-glycoprotein. We have selected human U-937 cells for clones resistant to the cytotoxic agents doxorubicin (U-A20) and vincristine (U-V20). The results demonstrate that P-glycoprotein-positive U-A20 and U-V20
