Models of growth hormone (GH) rhythmogenesis which we and others have presented suggest that the GH pulses in the circulation are generated by a GH-releasing hormone (GHRH) oscillator with a 1 h periodicity. Here we examine the possibility that this

The mechanism of function of the bacterial flagellar switch, which determines the direction of flagellar rotation and is essential for chemotaxis, has remained an enigma for many years. Here we show that the switch complex associates with the membran

A myriad of proteins and peptides can be identified in normal human urine. These are derived from a variety of sources including glomerular filtration of blood plasma, cell sloughing, apoptosis, proteolytic cleavage of cell surface glycosylphosphatid

Exosomes were initially thought to be a mechanism for removing unneeded membrane proteins from reticulocytes. Current studies have shown that the process of exosome formation extends to many mammalian cells. This concise review highlights the finding

Although red cells are generally associated with significant glucose transport and dependence on glycolysis, the mature red cells of some species (e.g. pig) show very low glucose transport, The generally low level of glucose transport in mature mamma

A cDNA clone named L21 was isolated from L6 rat muscle cells by complementation of a yeast proline transport mutant. L21 cDNA has 2,268 bp and codes for a peptide of 228 amino acids with four potential transmembrane domains. The amino acid sequence o

In contrast with other mammalian granulocytes, human granulocytes rapidly cleave the transferrin receptor (TFR) from sheep exosomes. Proteolysis of TFR from exosomes is more rapid and more extensive than that from the sheep reticulocyte cell surface

The presence of the heat shock protein (hsp-70) has been detected in exocytosed vesicles (which are named exosomes) from mammalian and avian immature red cells (i.e. reticulocytes) as well as from a differentiating avian erythroleukaemic cell line. T

Injection of mRNA from GF-14 cells (a mouse lymphocyte cell line) into Xenopus oocytes led to the expression of a transport activity characteristic of amino acid transport system A, i.e., Na+ dependent and recognizing aminoisobutyric acid and its met
