Malignancy
NO
We analyze pineal parenchymal tumors and embryonal tumors in CNS by immunohistochemistry for evidence of melatonin synthesis.
Others
We will make the antibody against hydroxyindol-O-methyltransferase (HIOMT) and analyze normal pineal glands and the other human organs by immunohistochemistry for evidence of melatonin synthesis. We will further analyze the correlation of the expression of HIOMT with the histological differentiation of PPTs.
Confirmatory
Explanatory
Not applicable
Control tissue, consisting of cerebrum, cerebellum, brain stem, spinal cord, dorsal root ganglion, pineal gland, pituitary gland, thyroid gland, parathyroid gland, adrenal gland, lung, heart, liver, spleen, pancreas, stomach, duodenum, small intestine, colon, kidney, prostate, testis, ovary, and bone marrow, was obtained from patients without neurologic disease and without pathologic abnormalities. Tumor specimens consisted of 8 PPTs (one PC, four PPTIDs, three PB), 3 central nervous system primitive neuroectodermal tumors (PNET), and 8 medulloblastomas (MB). We analyze normal pineal glands, the other human organs, PPTs, and embryonal tumors in CNS by immunohistochemistry for evidence of melatonin synthesis. We further analyse the correlation of the expression of HIOMT with the histological differentiation of PPTs.

Partially published
In human tissue, HIOMT was expressed in retinal cells, pineal parenchymal cells, neurons of the Edinger-Westphal nucleus, microglia, macrophages, thyroid follicular epithelium, principal and oxyphil cells of parathyroid gland, adrenal cortical cells, hepatic parenchymal cells, renal tubule epithelial cells, and enteroendocrine cells of stomach and duodenum. HIOMT was expressed in all PPTs studied. The ratio of HIOMT-immunoreactive cells successively decreased in the following tumors: pineocytoma, pineocytomatous area of PPTIDs, PPTID, pineoblastomatous area of PPTIDs, and pineoblastoma. In one of three PNETs and four of eight MBs, a few HIOMT-immunoreactive cells were observed. HIOMT immunohistochemistry is useful in diagnosing PPTs and may be one of the predictive factors affecting the survival of PPTs.
