摘要:
Human MARK genes are identified as modulators of the p53 pathway, and thus are therapeutic targets for disorders associated with defective p53 function. Methods for identifying modulators of p53, comprising screening for agents that modulate the activity of MARK are provided.

摘要:
Rhomboid Related Proteins (RRPs), involved in the EGFR signaling pathway, are provided. Transgenic, nonhuman mammals containing a transgene encoding an RRP polypeptide or a gene effecting the expression of an RRP polypeptide, along with methods of modulating the interaction of RRP proteins with their pathway members, and methods of screening for agents that modulate the interaction of an RRP polypeptide with an RRP binding target, such as RRP-specific antibodies and small molecules identified in high throughput screens, are also provided. Modulating agents identified using the methods of the invention can be used to specifically inhibit growth of tumor cells that overexpress an RRP protein.
摘要:
Novel compositions are provided for modulating growth, particularly of tumor cells, which compositions are combinations of Oncostatin M, and one or both of transforming growth factors or .gamma.-interferons, or analogs thereof. In addition, a novel transforming growth factor is provided, designated TGF-.beta.2, as well as methods for its preparation.
摘要:
Type III TGF-.beta. receptor is identified in and purified from normal human embryonic palatal mesenchyme (HEPM) cells and the purified product characterized structurally and functionally. HEPM cells were found to express high levels of the type III TGF-.beta. receptor and were found to significantly down-regulate two classes of TGF-.beta. receptor binding site. Purification of the type III TGF-.beta. receptor from solubilized HEPM cell membranes by affinity chromatography yielded a biologically active protein of about 205 kd which specifically binds both the recombinant and natural forms of TGF-.beta.1 and TGF-.beta.2, with affinity dissociation constants in the picomolar range.
摘要:
The use of TGF-.beta. to inhibit HIV infection and/or replication is described. Both mature and precursor forms of TGF-.beta. are efficacious in inhibiting production of HIV. The TGF-.beta. used to inhibit HIV may be obtained from natural sources or may be produced by recombinant DNA or chemical synthetic techniques. TGF-.beta.1 and/or TGF-.beta.2 may be used. Additionally, hybrid TGF-.beta.1/.beta.2 molecules may also be utilized.
