Abstract
Methods are provided for monitoring the condition of smooth muscles for abnormalities such as undesirable proliferation, and thereby monitoring for the presence of certain diseases such as transplant rejection, asthma and arteriosclerosis. A patient can have a sample taken from a site suspected to be subject to the disease. The sample is analyzed for the extent of presence of selenium binding protein, or phosphorylated forms thereof. Modified expression of the marker protein in the sample, or its absence, indicate the presence of such a disease. One may homogenize the sample and look for the presence or absence of a distinctly sized protein fragment resulting from the marker protein as a means of analyzing for the presence of the marker protein in the sample.
Claims16
A method of monitoring whether an animal is experiencing a disease and/or adverse condition involving smooth muscle cell abnormalities, the method comprising:
- analyzing a sample taken from the animal for the degree of presence of a protein selected from the group consisting of:
- (a) phosphorylated proteins having at least 95 percent homology to phosphorylated SEQ. ID NO. 1 in a form in which at least a tyrosine of SEQ. ID NO. 1 has been phosphorylated;
- (b) phosphorylated proteins having at least 95 percent homology to phosphorylated SEQ. ID NO. 2 in a form in which at least a tyrosine of SEQ. ID NO. 2 has been phosphorylated;
- (c) proteins having at least 95 percent homology to SEQ. ID NO. 1;
- and
- (d) proteins having at least 95 percent homology to Seq. ID NO. 2.
A method of monitoring whether a transplant selected from the group consisting of transplanted organs, transplanted tissues, and transplanted cells is being rejected by an animal recipient of the transplant, comprising:
- analyzing a sample taken from the recipient for the degree of presence of a protein selected from the group consisting of:
- (a) phosphorylated proteins having at least 95 percent homology to phosphorylated SEQ. ID NO. 1 in a form in which at least a tyrosine of SEQ. ID NO. 1 has been phosphorylated;
- (b) phosphorylated proteins having at least 95 percent homology to phosphorylated SEQ. ID NO. 2 in a form in which at least a tyrosine of SEQ. ID NO. 2 has been phosphorylated;
- (c) proteins having at least 95 percent homology to SEQ. ID NO. 1;
- and
- (d) proteins having at least 95 percent homology to SEQ. ID NO. 2.
A phosphorylated protein fragment in a form isolated from other proteins having a size greater than 100 kDa, wherein the protein is between 20 and 80 kDa in size and is selected from the group consisting of a fragment of phosphorylated SEQ. ID NO. 1 in a form in which at least a tyrosine of SEQ. ID NO. 1 has been phosphorylated and a fragment of phosphorylated SEQ. ID NO. 2 in a form in which at least a tyrosine of SEQ. ID NO. 2 has been phosphorylated.
