Mutations in TRPML1 cause the lysosomal storage disease mucolipidosis type IV (MLIV). The role of TRPML1 in cell function and how the mutations cause the disease are not well understood. Most studies focus on the role of TRPML1 in constitutive membrane trafficking to and from the lysosomes. However, this cannot explain impaired neuromuscular and secretory cells' functions that mediate regulated...
abstract this study examines the effect of teaching lexical inferencing strategies on developing reading comprehension skill of iranian advanced efl learners. participants were female students of meraj and shokouh institudes of garmsar a quasi-experimental design using two intact advanced classes of efl students at meraj and shokouh institutes. as the first step, a general toefl proficiency te...
An electron microscopic investigation was performed to examine the ultrastructural changes occurring in the rabbit oviductal epithelium after human chorionic gonadotropin (HCG) administration. Mainly, the non-ciliated secretory cells proved to be affected by the hormonal treatment which resulted in qualitative and quantitative modifications of the secretory patterns differently expressed in the...
BACKGROUND Secretory carcinoma of the male breast (juvenile carcinoma) is a rare neoplasm. Only a few cases have been reported in the literature. CASE REPORT We report here a case in a 17-year old male presenting with recurrent breast swelling. CONCLUSIONS Though considered an indolent neoplasm, secretory carcinoma does metastasise to lymph nodes and recur after local excision. Surgery in f...
A new procedure is described for the preparation of highly purified and stable secretory vesicles from adrenal medulla. Two forms of acetylcholinesterase, a membrane bound form as well as a soluble form, were found within these vesicles. The secretory vesicles, isolated by differential centrifugation, were further purified on a continuous isotonic Percoll gradient. In this way, secretory vesicl...
Treatment of rats with 0.5-25 mumol/100 g body weight of colchicine for 1 h or more caused an inhibition of hepatic protein synthesis. This effect was not seen if animals were exposed to colchicine for less than 1 h. The delayed inhibition of protein synthesis affected both secretory and nonsecretory proteins. Treatment with colchicine (15 mumol/100 g) for 1 h or more caused the RNA content of ...
GABA (gamma-aminobutyric acid) is the primary inhibitory neurotransmitter in brain. The fast inhibitory effect of GABA is mediated through the GABA(A) receptor, a postsynaptic ligand-gated chloride channel. We propose that GABA can act as a ligand chaperone in the early secretory pathway to facilitate GABA(A) receptor cell surface expression. Forty-two hours of GABA treatment increased the surf...
AbstractMeningiomas are slow growing, extra axial brain tumors that originating from the meningothelial cells of arachnoid. Meningiomas most common tumors, however secretory meningiomas extremely rare variant and can be confused radiologically pathologically with malignant tumors. A 48 years old male was presented a complaint headache visual impairment in left eye. Magnetic resonance imaging re...
Recent evidence suggests that secretory vesicle formation from the TGN is regulated by cytosolic signaling pathways involving small GTP-binding proteins, heterotrimeric G proteins, inositol phospholipid metabolism, and protein serine/threonine phosphorylation. At the cell surface, protein phosphorylation and dephosphorylation on tyrosine residues can rapidly modulate cytosolic signaling pathway...
BACKGROUND In contrast with the histamine2 (H2) blockers, proton pump inhibitors have not been shown to give rebound hypersecretion of acid. Taking into consideration the hyperplasia of the enterochromaffin-like (ECL) cell provoked by hypergastrinaemia secondary to profound acid inhibition and the central role of histamine from ECL cells in the regulation of acid secretion, the lack of any rebo...
