The effect of neuronal cells on the functional properties of intestinal epithelial cells was examined by using an in vitro coculture system. Two cell lines, Caco-2 and PC12, were respectively used as intestinal epithelial and enteric neuronal cell models. Coculture of differentiated Caco-2 cells with PC12 caused a significant decrease in the transepithelial electrical resistance (TER) value of ...
To address the means by which diversity of neuronal morphology is generated, we have isolated and characterized naturally occurring variants of rat PC12 pheochromocytoma cells that exhibit altered neurite outgrowth properties in response to nerve growth factor (NGF). We describe here a PC12 cell sub-clone, designated PC12-clone 41 (PC12-C41), that displays significant increases in neurite abund...
Expression of RNA for the NMDAR1 subunit of the N-methyl-D-aspartate receptor was detected by Northern hybridization in both nerve growth factor-differentiated and undifferentiated rat pheochromocytoma (PC12) cells. The NMDA receptor type 1 (NMDAR1) message in PC12 cells was similar in size to that expressed in hippocampal neurons. PC12 cell cDNAs that were amplified by polymerase chain reactio...
Human T-cell leukemia virus type I (HTLV-I) Tax protein induces the expression of host cellular genes, some of which are crucial in cell proliferation and differentiation. We examined the mechanisms by which HTLV-I Tax protein induces phenotypic changes in PC12 cells. We demonstrated that the HTLV-I Tax gene induces epithelioid changes and increases cell-cell contact in PC12 cells. No change in...
The mechanical response of PC12 neurites under tension is investigated using a microneedle technique. Elastic response, viscoelastic relaxation, and active contraction are observed. The mechanical model proposed by Dennerll et al. [J. Cell Biol. 109, 3073 (1989).10.1083/jcb.109.6.3073], which involves three mechanical devices--a stiff spring kappa coupled with a Voigt element that includes a le...
Persistent stimulation of specific protein kinase pathways has been proposed as a key feature of receptor tyrosine kinases and intracellular oncoproteins that signal neuronal differentiation of rat pheochromocytoma (PC12) cells. Among the protein serine/threonine kinases identified to date, the p42/44 mitogen-activated protein (MAP) kinases have been highlighted for their potential role in sign...
سابقه و هدف: رده سلولی فئوکروموسیتوم رت (pc12)، در محیط کشت مناسب و تحت تاثیر عوامل القا کننده تمایز عصبی می-توانند به سلول هایی با فنوتیپ عصبی تبدیل شوند. زهر زنبور عسل حاوی اجزای مختلفی مانند فسفولیپاز 2 (pla2) است که به تنهایی اثرات تمایزی بر pc12 دارد، ولی اثر کل زهر بر آن مشخص نیست. لذا در این تحقیق، تاثیر زهر زنبور بر تمایز سلول های pc12 بررسی شد. روش بررسی: سلول های pc12 در محیط rpmi1640...

Purpose: The present study was designed to investigate the effect of hydrostatic pressure on cell viability, apoptosis induction, morphology and cell-substrate interactions of PC12 cells. Materials and Methods: PC12 as a neuronal cell line maintained in RPMI 1640 culture medium supplemented with 10% fetal bovine serum. PC12 cells were subjected to hydrostatic pressure. Experimental pressure con...
To explore the impact of the new derivatives cyclovirobuxine D (CBV-D) model of alcohol-induced injury in PC12 cells. The model of alcohol-induced injury in PC12 cells, new derivatives of the cyclovirobuxine D PC12 cells by MTT assay, Hoechst 33258 staining and lactate dehydrogenase (LDH) activity was measured. The new D derivatives cyclovirobuxine inhibit the damage caused by alcohol PC12 cell...
