Cajal bodies (CBs) are nuclear organelles that are usually identified by the marker protein p80-coilin. Because no orthologue of coilin is known in Drosophila melanogaster, we identified D. melanogaster CBs using probes for other components that are relatively diagnostic for CBs in vertebrate cells. U85 small CB-specific RNA, U2 small nuclear RNA, the(More)
The in vitro effects of thymosin fraction 5 (TF5) and lithium chloride (LiCl) on the ability of peripheral blood mononuclear cells (PBMC) obtained from 37 normal male donors and 33 male patients with AIDS-related complex (ARC) to respond to alloantigenic stimulation (mixed leukocyte reaction, MLR) and to produce interleukin 2 (IL-2) in response to mitogens(More)
Enhancers are defined by their ability to stimulate gene activity from remote sites and their requirement for promoter-proximal upstream activators to activate transcription. Here we demonstrate that recruitment of the p300/CBP-associated factor PCAF to a reporter gene is sufficient to stimulate promoter activity. The PCAF-mediated stimulation of(More)
A series of 2'-substituted chalcone derivatives has been found to show potent inhibition of the production of IL-1 beta from human peripheral blood monocytes stimulated with lipopolysaccharide (LPS), with IC50 values in the 0.2-5.0-microM range. Some members of the series have also shown inhibition of septic shock induced in mice by injection of LPS,(More)
The hypothalamo-neurohypophyseal complex (HNC) of the fetal guinea pig shows a dramatic increase in its content of vasopressin and neurophysin between the 40th and 55th days of gestation. The values for radioimmunoassayable hormone and binding protein are at day 40, 2 milliunits and less than 0.1 microgram; and at day 55, about 100 milliunits and 10(More)
Fragments of the anterior hypothalamus that contain supraoptic nuclei and short axonal segments from adult guinea pigs have been kept in organ culture for up to 15 days. Electron micrographs displayed intact nuclei, Nissl substance, Golgi bodies, and an ultrastructure characteristic of viable neurosecretory cells; by contrast, the surrounding neurophil(More)
The carrageenan pleurisy model, which is characterized by cellular influx and oedema, has been used to examine the effects of anti-inflammatory compounds such as naproxen. Interleukin-1alpha and beta (IL-1) are known to be pro-inflammatory mediators, and their roles in this model are unknown. Intrapleural injection of 1% viscarin carrageenan or saline was(More)
We have previously described the isolation of a clonal cell line (PC-G2) in which the level of tyrosine hydroxylase (TH), the rate-limiting step in the synthesis of the catecholamine neurotransmitters, is induced by nerve growth factor (NGF). We now report that epidermal growth factor (EGF) also induces TH in the PC-G2 cell line. Although EGF has been shown(More)
