Definitions

  • This invention relates, in part, to newly developed assays for detecting, diagnosing, monitoring, staging, and prognosticating cancers, particularly prostate cancer.
  • Cancer of the prostate is the most prevalent malignancy in adult males, excluding skin cancer, and is an increasingly prevalent health problem in the United States. In 1996, it was estimated that in the United States, 41,400 deaths would result from this disease, indicating that prostate cancer is second only to lung cancer as the most common cause of death in the same population. If diagnosed and treated early, when the cancer is still confined to the prostate, the chance of cure is significantly higher.
  • a common classification of the spread of prostate cancer was developed by the American Urological Association (AUA) .
  • the AUA classification divides prostate tumors into four stages, A to D.
  • Stage A microscopic cancer within prostate, is further subdivided into stages Al and A2.
  • Stage Al is a well-differentiated cancer confined to one site within the prostate.
  • Treatment is generally observation, radical prostatectomy, or radiation.
  • Sub-stage A2 is a moderately to poorly differentiated cancer at multiple sites within the prostate. Treatment is radical prostatectomy or radiation.
  • Stage B palpable lump within the prostate, is further subdivided into stages Bl and B2.
  • sub-stage Bl the cancer forms a small nodule in one lobe of the prostate.
  • the cancer forms large or multiple nodules, or occurs in both lobes of the prostate.
  • Treatment for both sub- stages Bl and B2 is either radical prostatectomy or radiation.
  • Stage C is a large cancer mass involving most or all of the prostate and is further subdivided into two stages.
  • the cancer forms a continuous mass that may have extended beyond the prostate.
  • sub-stage C2 the cancer forms a continuous mass that invades the surrounding tissue. Treatment for both these sub-stages is radiation with or without drugs.
  • the fourth stage is metastatic cancer and is also subdivided into two stages.
  • sub-stage Dl the cancer appears in the lymph nodes of the pelvis.
  • sub-stage D2 the cancer involves tissues beyond lymph nodes. Treatment for both these sub-stages is systemic drugs to address the cancer as well as pain.

  • Assay techniques that can be used to determine levels of gene expression, such as PSG of the present invention, in a sample derived from a host are well-known to those of skill in the art. Such assay methods include radioimmunoassays, reverse transcriptase PCR (RT-PCR) assays, immunohistochemistry assays, in si tu hybridization assays, competitive-binding assays, Western Blot analyses and ELISA assays. Among these, ELISAs are frequently preferred to diagnose a gene's expressed protein in biological fluids.
  • An ELISA assay initially comprises preparing an antibody, if not readily available from a commercial source, specific to PSG, preferably a monoclonal antibody.
  • reporter antibody generally is prepared which binds specifically to PSG.
  • the reporter antibody is attached to a detectable reagent such as radioactive, fluorescent or enzymatic reagent, for example horseradish peroxidase enzyme or alkaline phosphatase.
  • antibody specific to PSG is incubated on a solid support, e.g., a polystyrene dish, that binds the antibody. Any free protein binding sites on the dish are then covered by incubating with a non-specific protein such as bovine serum albumin.
  • a non-specific protein such as bovine serum albumin.
  • the sample to be analyzed is incubated in the dish, during which time PSG binds to the specific antibody attached to the polystyrene dish. Unbound sample is washed out with buffer.
  • a reporter antibody specifically directed to PSG and linked to horseradish peroxidase is placed in the dish resulting in binding of the reporter antibody to any monoclonal antibody bound to PSG. Unattached reporter antibody is then washed out.
  • Reagents for peroxidase activity including a colorimetric substrate are then added to the dish.
  • the amount of color developed in a given time period is proportional to the amount of PSG protein present in the sample. Quantitative results typically are obtained by reference to a standard curve .
  • a competition assay may be employed wherein antibodies specific to PSG attached to a solid support and labeled PSG and a sample derived from the host are passed over the solid support and the amount of label detected attached to the solid support can be correlated to a quantity of PSG in the sample.
  • Nucleic acid methods may be used to detect PSG mRNA as a marker for prostate cancer.
  • Polymerase chain reaction (PCR) and other nucleic acid methods such as ligase chain reaction (LCR) and nucleic acid sequence based amplification (NASABA)
  • PCR polymerase chain reaction
  • LCR ligase chain reaction
  • NASABA nucleic acid sequence based amplification
  • RT-PCR reverse- transcriptase PCR
  • cDNA complementary DNA
  • RT-PCR can thus reveal by amplification the presence of a single species of mRNA. Accordingly, if the mRNA is highly specific for the cell that produces it, RT-PCR can be used to identify the presence of a specific type of cell.
  • Hybridization to clones or oligonucleotides arrayed on a solid support can be used to both detect the expression of and quantitate the level of expression of that gene.
  • a cDNA encoding the PSG gene is fixed to a substrate.
  • the substrate may be of any suitable type including but not limited to glass, nitrocellulose, nylon or plastic.
  • At least a portion of the DNA encoding the PSG gene is attached to the substrate and then incubated with the analyte, which may be RNA or a complementary DNA (cDNA) copy of the RNA, isolated from the tissue of interest.
  • Hybridization between the substrate bound DNA and the analyte can be detected and quantitated by several means including but not limited to radioactive labeling or fluorescence labeling of the analyte or a secondary molecule designed to detect the hybrid. Quantitation of the level of gene expression can be done by comparison of the intensity of the signal from the analyte compared with that determined from known standards. The standards can be obtained by in vitro transcription of the target gene, quantitating the yield, and then using that material to generate a standard curve.
  • Bodily fluids useful in the present invention include blood, urine, saliva, or any other bodily secretion or derivative thereof.
  • Blood can include whole blood, plasma, serum, or any derivative of blood.
  • Subsetting is similar to library comparison but allows the identification of clones expressed in a pool of libraries and absent or expressed at a lower level in a second pool of libraries.
  • Transcript Imaging lists all of the clones in a single library or a pool of libraries based on abundance. Individual clones can then be examined using Electronic Northerns to determine the tissue sources of their component ESTs.
  • Incyte has identified subsets of ESTs with a potential protein function based on homologies to known proteins. Some examples in this database include Transcription Factors and Proteases. Some leads were identified by searching in this database for clones whose component ESTs showed disease specificity.
