2Effect of cholecystokinin and secretin on contractile activity of isolated gastric muscle strips in guinea pigs显示文摘AIM To study the effect of cholecystokinin-octapeptide(CCK-8)and secretin on contractileactivity of isolated gastric muscle strips inguinea pigs.METHODS Each isolated gastric muscle stripwas suspended in a tissue chamber containing5 mL Krebs solution constantly warmed by waterjacked at 37℃ and supplied with a mixed gas of95% O2 and 5% CO2 After incubating for lhunder 1 g tension,varied concentrations of CCK-8 and secretin were added respectively in thetissue chamber and the contractile response wasmeasured isometrically on ink-writing recorders.RESULTS CCK-8 could increase①all regionalcircular and longitudinal muscular tension at rest(fundus LM 19.7%±2.1%,P<0.01;fundus CM16.7%±2.2%,P<0.01;gastric body LM 16.8%±2.3%,P<0.01;body CM 12.7%±2.6%,P<0.01;antrum LM 12.3%±1.3%,P<0.01;antrum CM 16.7%±4.5%,P<0.01;pylous CM12.7%±5.0%,P<0.05);②contractilefrequencies of body LM,both LM and CM ofantrum and pylorus CM(5.1/min±0.2/min to5.6/min±0.2/min,5.9/min±0.2/min to 6.6/min±0.l/min,5.4/min±0.3/min to 6.3/min±0.4/rain,1.3/min±0.2/min to 2.3/min±0.3/min,respectively,P<0.05);③the mean contractileamplitude of antral circular muscle(58.6%±18.4%,P<0.05)and ④the motility index ofpylorus CM(145.0%±23.8%,P<0.01),butdecrease the mean contractile amplitude ofgastric body and antral LM(-10.3%±3.3%,-10.5%±4.6%,respectively,P<0.05).All the CCK-8 effects were not blocked by atropine orindomethacin.Secretin had no effect on gastricsmooth muscle activity.CONCLUSION CCK-8 possessed bothexcitatory and inhibitory action on contractileactivity of different regions of stomach in guineapigs.Its action was not mediated via cholinergicM receptor and endogenous prostagiandinreceptor,Li W Zheng TZ Qu SY 2000World Journal of Gastroenterology2000,6,1:13
3Visualizing the microtubule-associated protein tau in the nucleus显示文摘Although tau is mainly known as an axonal microtubule-associated protein,many studies indicate that it is not restricted to this subcellular compartment.Assessing tau’s subcellular distribution,however,is not trivial as is evident from transgenic mouse studies.When human tau is over-expressed,it can be immunohistochemically localized to axons and the somatodendritic domain,modeling what is found in neurodegenerative diseases such as Alzheimer’s disease.Yet,in wild-type mice,despite its abundance,tau is difficult to visualize even in the axon.It is even more challenging to detect this protein in the nucleus,where tau has been proposed to protect DNA from damage.To establish a framework for future studies into tau’s nuclear functions,we compared several methods to visualize endogenous nuclear tau in cell lines and mouse brain.While depending on the fixation and permeabilization protocol,we were able to detect nuclear tau in SH-SY5Y human neuroblastoma cells,we failed to do so in N2a murine neuroblastoma cells.As a second method we used subcellular fractionation of mouse tissue and found that in the nucleus tau is mainly present in a hypophosphorylated form.When either full-length or truncated human tau was expressed,both accumulated in the cytoplasm,but were also found in the nuclear fraction.Because subcellular fractionation methods have their limitations,we finally isolated nuclei to probe for nuclear tau and found that the nuclei were free of cytoplasmic contamination.Together our analysis identifies several protocols for detecting tau in the nucleus where it is found in a less phosphorylated form.LU Jing LI Ting HE RongQiao BARTLETT Perry F GTZ Jürgen 2014Science China(Life Sciences)2014,57,4:11
