Endothelin (ET) peptides stimulate AVP secretion via ETB receptors at hypothalamic loci. Nitric oxide modulates the actions of ET in the cardiovascular system and also influences neurotransmission and specifically suppresses firing of magnocellular neurons. The purpose of these studies was to ascertain whether nitric oxide, generated in response to ETB receptor stimulation, buffers the stimulat...

BACKGROUND AND AIMS Understanding the fate and dynamics of cells during callus formation is essential to understanding totipotency and the mechanisms of somatic embryogenesis. Here, the fate of leaf explant cells during the development of embryogenic callus was investigated in the model legume Medicago truncatula. METHODS Callus development was examined from cultured leaf explants of the high...

OBJECTIVE In this study, we aimed to explore prognostic value of MASTL (microtubule-associated serine/threonine kinase-like) in breast cancer patients on the basis of ER status and molecular subtypes. MATERIALS AND METHODS The raw microarray data (GDS5666) of 4T1 derived bone-aggressive explant and primary tumor explant were reanalyzed to identify the dysregulated genes. To pool previous anno...

AIMS To develop an in vitro assay for the putative glutamyl endopeptidase, "aggrecanase", which is thought to degrade cartilage aggrecan, and to examine the role of the enzyme in tumour necrosis factor stimulated aggrecan cleavage. METHODS Aggrecan fragments released by bovine nasal cartilage explants, with and without exposure to tumour necrosis factor alpha, were purified and analysed by we...

The present study investigated the influence of trophic factors on the expression of cocaine- and amphetamine-regulated transcript peptide (CARTp) in guinea-pig cardiac ganglia maintained in explant culture. In acutely isolated cardiac ganglia preparations, <1% of the cholinergic cardiac neurons exhibited CARTp immunoreactivity. In contrast, this number increased to >25% of the cardiac neurons ...

Availability of quality seeds in production krisan (Chrysanthemum morifolium Ramat cv Dewi ratih) cultivation is still rare, therefore research on seed multiplication through tissue culture needed. The media used relatively expensive for home industry. This study aims to determine the respond leaf and stem explants using foliar fertilizers (Growmore, Gandasil D Mutiara) as an alternative callus...
