The emerging insights into glycan functionality direct increasing attention to monitor core modifications of N-glycans and branch-end structures. To address this issue in histochemistry, a panel of lectins with respective specificities was devised. The selection of probes with overlapping specificities facilitated to relate staining profiles to likely(More)
To study the involvement of the IGFs in mammary development and lactation of the cow, the temporal expressions of IGF-I and -II, its receptor type 1 (IGFR-1), IGF-binding proteins (IGFBPs)-1 to -6 and GH receptor (GHR) mRNA were examined. This was carried out for different stages of mammogenesis, lactogenesis, galactopoiesis and involution in the bovine(More)
It is now well established that oestrogen and progesterone are absolutely essential for mammary gland development. Lactation can be induced in non-pregnant animals by sex steroid hormone treatment. Most of the genomic actions of oestrogens are mediated by two oestrogen receptors (ER)-alpha and ERbeta, and for gestagens in ruminants by the progesterone(More)
Nitric oxide synthases (NOS) account for the endogenous production of nitric oxide (NO), a small and permeable bioreactive molecule. NO is known to act as a paracrine mediator during various processes associated with female reproduction. In the present study, the mRNA expression of the endothelial (eNOS) and inducible (iNOS) NO synthases were examined in(More)
The endometrium plays a central role among the reproductive tissues in the context of early embryo-maternal communication and pregnancy. It undergoes typical changes during the sexual/oestrous cycle, which are regulated by the ovarian hormones progesterone and oestrogen. To identify the underlying molecular mechanisms we have performed the first holistic(More)
By reverse transcription-polymerase chain reaction (RT-PCR) the transcript of the growth hormone receptor (GHR) was proved in bovine placentae of different gestational stages. Using non-radioactive in situ hybridization (ISH) the mRNA encoding GHR was localized in the uterine epithelium, glands, vessels and amniochorion of the placenta from the sixth week(More)
A panel of monoclonal antibodies to the growth hormone (GH) receptor/binding protein was used to demonstrate the existence and detail the expression of GH receptors in the cerebellum of 2, 10, 28 days old postnatal and adult rats and 10, 20 days old and adult rabbits by immunohistochemistry to define potential targets for endogenous GH action in the(More)
The olfactory epithelium is unique in the mammalian nervous system as it is a site of continual neurogenesis. Constant turnover of primary sensory neurons in the periphery results in continuous remodeling of neuronal circuits and synapses in the olfactory bulb throughout life. Most of the specific mechanisms and factors that control and modulate this(More)
