The signet-ring cells were negative for synaptophysin, chromogranin A, and CD57 (
PGP9.5).
The reaction mixture for polymerase chain reaction (PCR) contained 2 x PCR reaction mixture buffer 10 [micro]L, cDNA 1 [micro]L and specific primers (20 [micro]m each primer), Oct4 and c-kit (annealing at 52[degrees]C, 35 cycles), THY-1 and
PGP9.5 (annealing at 56[degrees]C, 35 cycles).
Results: The highest
PGP9.5 (94.6[+ or -]0.4) and the lowest c-Kit positive (25.1[+ or -]0.7) in Percoll method was significantly (pL0.001) achieved in 32[degrees]0 percoll gradient.
There is variable expression of other neuroectodermal antigens including NSE (positive in this case), synaptophysin, neurofilament, GFAP and
PGP9.5.
This is the first demonstration of antibodies to pro-MMP-7 in cancer patients, although numerous circulating antitumor antibodies have been detected in cancer patient sera, with identified antigens such as Her2/neu (32), thymidine phosphorylase (16), and
PGP9.5 (30).
Changes of protein gene product 9.5 (
PGP9.5) immunoreactive nerves in inflamed appendix.
CD 117, DOG 1, S100, CD34, chromogranin, synaptophysin, CD56, CD57,
PGP9.5, and desmin were all negative.
Endocrine cells in the GI and pancreatobiliary tracts and NETs are labeled by neuroendocrine markers, including synaptophysin, chromogranin A, CD56/NCAM1, Leu7/ B3GAT1, protein gene product 9.5 (
PGP9.5), and neuronspecific enolase.
Parafibromin, galectin-3,
PGP9.5, Ki67, and cyclin D1: using an immunohistochemical panel to aid in the diagnosis of parathyroid cancer.
Immunostains showed the tumour cells were negative for chromogranin, CK7, CK20,
PGP9.5 serotonin, glucagon, somatostatin, gastrin and insulin (Fig.
