Words similar to potentiating
Example sentences for: potentiating
How can you use “potentiating” in a sentence? Here are some example sentences to help you improve your vocabulary:
It has been previously shown that potentiating effect of phorbol esters on IFNg-dependent MHCII induction in THP-1 monocytic cell line was associated with the increase in synthesis of IFNg receptors [ 19 ] . For that reason, we questioned whether PMA could produce similar changes in LS1034 colon carcinoma cells.
It has been shown that hepatocytes exposed to 100 mM ethanol for 16 hr have a higher activity of p38MAPK induced by EGF treatment [ 41 ] . If in our experiments PMA did act through Ser727 phosphorylation of STAT1, the potentiating effect of ethanol can possibly be explained by its ability to stimulate the MAPK kinase cascade.
The secreted form has been referred to as megakaryocyte potentiating factor (MPF) for its ability to stimulate the megakaryocyte colony forming activity of murine IL-3 in mouse bone marrow cell culture [ 23 24 ] . Mesothelin expression is induced in a variety of cancers including ovarian, pancreatic, lung, and cervical cancer [ 25 26 ] . The soluble portion of mesothelin has drawn attention as a potential serum tumor marker since it is highly over-expressed in patients with ovarian carcinomas and pancreatic adenocarcinomas [ 27 28 ] .
Chloride channels or chloride ions are known to influence cAMP-stimulated steroidogenesis by adrenal cells [ 29 ] , human chorionic gonadotropin (hCG)-stimulated steroidogenesis by amphibian follicle-enclosed oocytes [ 56 ] , as well as LH-stimulated steroidogenesis in rat Leydig cells [ 29 ] , MA-10 cells [ 59 ] , and chicken GC [ 35 ] . In mammalian cells, removal of extracellular chloride stimulates basal and protein kinase A (PKA)-dependent steroid hormone production by increasing the expression of StAR and potentiating the effects of submaximal concentrations of cAMP [ 29 59 ] . The proposed mechanism of action involves chloride efflux, depolarization of the mitochondrial and plasma membranes, and alterations to protein synthesis and cholesterol transport [ 29 59 ] .
A potentiating effect of PMA has been reported in thyroid carcinoma cells [ 20 ] but, in contrast to LS1034 cells, normal IFNg response in those cells was only partially lost as a result of malignant transformation.
