Bone morphogenetic protein 9 (BMP9), also known as growth differentiation factor 2 (GDF2), is a member of the transforming ? (TGF ?) superfamily. Although BMP9 plays pivotal roles during development, including angiogenesis, hematopoiesis, hepatogenesis, osteogenesis, and glucose metabolism, little information available for expression in central nervous system (CNS). We, thus, investigated adult...

23 Iron is essential for male fertility and disruptions in iron balance lead to impairment of testicular 24 function. The divalent metal transporter DMT1 is a key modulator of transferrin and non-transferrin 25 bound iron homeostasis. As a first step in determining the role of DMT1 in the testis, we have 26 determined the pattern of DMT1 expression in the developing and adult rat testis. Northe...

We measured the ability of neonatal to adult MRC-Wistar rat and Syrian hamster tissues to convert the esophageal carcinogen methyl-n-amylnitrosamine (MNAN) into the stable metabolites 2- to 5-hydroxy-MNAN and 3- and 4-oxo-MNAN. Slices or pieces of freshly removed tissues were incubated for 3 h with 23 microM MNAN and dichloromethane extracts were analyzed by gas chromatography-thermal energy an...

We measured the ability of neonatal to adult MRC-Wistar rat and Syrian hamster tissues to convert the esophageal carcinogen methyl-namylnitrosamine (MNAN) into the stable metabolites 2to 5-hydroxyMNAN and 3and 4-oxo-MNAN. Slices or pieces of freshly removed tissues were incubated for 3 h with 23 ¿tM NAN and dichloromethane extracts were analyzed by gas chromatography-thermal energy analysis. T...

The localization of vimentin (VIM) and glial fibrillary acidic protein (GFAP) was studied immunohistochemically in adult rat optic nerve. Consecutive Epon semithin tissue sections were immunostained respectively for VIM or GFAP. With this method, both antigens were detected in consecutive sections of the same cell. According to our results, most astrocytes in the adult rat optic nerve showed co...

The influence of neonatal serotonergic lesion on adult behavior in locomotor and depression models was studied in male Wistar rats. When 3-day-old rats were injected intracisternally with 5,7-dihydroxytryptamine (5,7-DHT), a marked depletion of brain 5-HT was observed when animals were killed 3 months after the treatment. Brain catecholamine content was generally not changed by neurotoxin treat...
