The nature and content of lytic bodies and the localization of acid phosphatase (AcPase) activity were investigated in mammotrophic hormone-producing cells (MT) from rat anterior pituitary glands. MT were examined from lactating rats in which secretion of MTH(1) was high and from postlactating rats in which MTH secretion was suppressed by removing the suckling young. MT from lactating animals c...
(Morphology and histochemistry of glandular trichomes of Cordia verbenacea DC. (Boraginaceae) leaves). The objective of this work was to study, using light and fluorescence microscopy and scanning electron microscopy, the morphology and secretory products of glandular trichomes of Cordia verbenacea DC. (Boraginaceae), known as ‘baleeira’, a species used in folk medicine as anti-inflammatory, an...
Recent amino acid sequence data suggest that trypsin-like and carboxypeptidase B-like activities are required for the processing of pituitary prohormones--e.g., pro-opiocortin (pro-adrenocorticotropin/lipotropin) and provasopressin in secretory granules. In this study the existence of a carboxypeptidase B activity in purified secretory granules from anterior, intermediate, and neural lobes of r...
The hepatitis B virus envelope gene encodes three transmembrane proteins in frame; S, the product of S gene; M, the product of M (pre-S2 + S) gene; and L, the product of L (pre-S1 + pre-S2 + S) gene. Unlike the S and M proteins, attempts to efficiently synthesize L proteins and assemble them into L protein particles in various eukaryotic cells have been unsuccessful, probably because of the pre...
Evolution has resorted to nitric oxide (NO), a tiny, reactive radical gas, to mediate both servoregulatory and cytotoxic functions. This article reviews how different forms of nitric oxide synthase help confer specificity and diversity on the effects of this remarkable signaling molecule.
In different endocrine cells of the rat, Smith and interpreted as a cellular mechanism for disposing Farquhar (1) and Orci et al . (2) described the inof excess secretory product under certain expericorporation of secretory granules within lysosomal mental (1) or metabolic conditions (2, 3). Granubodies. This process, called granulolysis (2) or lolysis, at a low rate, is also present under norm...
bacterial utilize a multitude of methods to secretion of specific substrate across phospholipid membranes. these bacterial strategies can play many roles in promoting bacterial process, from enhancing pathogenesis to bacterial response to environmental condition. the secretion in bacterial species transfer and release performance substance such as proteins, enzymes and metabolites to environmen...
background: the aim of this study was to compare superoxide dismutase (sod) activity in fasciola hepatica and fasciola gigantica parasites. materials: f. gigantica and f. hepatica helminths were collected from abattoir and cultured in buffer media for 4 h at 37 °c. excretory-secretory (es) products were collected, centrifuged and stored at - 20 ◦ c. e-s protein concentration was measured by bra...
