Immunohistochemical localization of galactosyltransferase in the normal human ovary and fallopian tube. 1984

B W Davis, and E G Berger, and G W Locher, and M Zeller, and A Goldhirsch

Galactosyltransferase (UDP-galactose: 2-acetamido-2-deoxy beta-D-glucopyranose beta-(1-4) transferase) in human tissue specimens from ovaries and the corresponding fallopian tubes was localized immunohistochemically for light microscopy. An affinity-purified rabbit anti-human milk galactosyltransferase antibody was used. Intracellular galactosyltransferase was found to be localized to the juxtanuclear (Golgi) region of the secretory cells of the fallopian-tube epithelium and to the ovarian stromal cells involved in steroid-hormone production. Cell-surface galactosyltransferase was localized to ciliated cells of the fallopian-tube epithelium. During the follicular phase of the menstrual cycle, galactosyltransferase was found only in the Golgi regions of theca interna cells of the ovarian graafian follicle, and in the fallopian tube was found predominantly on the cilia of epithelial cells. During the luteal phase, galactosyltransferase was abundant in the Golgi regions of granulosa lutein cells of the corpus luteum, and was predominant in the secretory cells of the tubal epithelium. Galactosyltransferase was not detected on the mesothelial ovarian surface. The results demonstrate that the cellular distribution and location of galactosyltransferase correlates with phenotypic differentiation and varies during the human female hormonal cycle.

UI MeSH Term Description Entries
D007120 Immunochemistry Field of chemistry that pertains to immunological phenomena and the study of chemical reactions related to antigen stimulation of tissues. It includes physicochemical interactions between antigens and antibodies.
D008297 Male Males
D008598 Menstruation The periodic shedding of the ENDOMETRIUM and associated menstrual bleeding in the MENSTRUAL CYCLE of humans and primates. Menstruation is due to the decline in circulating PROGESTERONE, and occurs at the late LUTEAL PHASE when LUTEOLYSIS of the CORPUS LUTEUM takes place.
D008875 Middle Aged An adult aged 45 - 64 years. Middle Age
D010053 Ovary The reproductive organ (GONADS) in female animals. In vertebrates, the ovary contains two functional parts: the OVARIAN FOLLICLE for the production of female germ cells (OOGENESIS); and the endocrine cells (GRANULOSA CELLS; THECA CELLS; and LUTEAL CELLS) for the production of ESTROGENS and PROGESTERONE. Ovaries
D005187 Fallopian Tubes A pair of highly specialized canals extending from the UTERUS to its corresponding OVARY. They provide the means for OVUM transport from the ovaries and they are the site of the ovum's final maturation and FERTILIZATION. The fallopian tube consists of an interstitium, an isthmus, an ampulla, an infundibulum, and fimbriae. Its wall consists of three layers: serous, muscular, and an internal mucosal layer lined with both ciliated and secretory cells.
