| 1 | Influence of ellagic acid on prostate cancer cell proliferation:A caspase-dependent pathway显示文摘Objective:To evaluate the effect of allagic acid treatment on the cell viability of human prostate cancer cells.Methods:Ellagic acid(10-100 mol/L) treatment(48 h) of human prostate carcinoma PC3 cells was found to result in a dose-dependent inhibition of cell growth and apoptosis of PC3 cells as assessed by MTT assay,western blotting.flow cytometry and confocal microscopy.Results:We observed that ellagic acid treatment of PC3 cells resulted in a dose dependent inhibition of cell growth/cell viability.This ellagic acid caused cell growth inhibition was found to be accompanied by induction of apoptosis,as assessed by the cleavage of poly (ADP-ribose) polymerase(PARP) and morphological changes.Further,induction of apoptosis accompanied a decrease in the levels of antiapoptotic protein Bcl-2 and increase in proapoptotic protein Bax.thus shifting the Bax:Bcl-2 ratio in favor of apoptosis.Ellagic acid treatment of PC3 cells was also found to result in significant activation of caspases,as shown by the dose dependent decrease in the protein expression of procaspase-3,-6.-8 and -9.This ellagic acid-mediated induction of apoptosis was significantly(80%-90%) inhibited by the caspase inhibitor N-benzyloxycarbonyl-Val-Ala-Asp(OMe)-fluoromethylketone(Z-VAD-FMK).Thus these data suggested an essential role of caspases in ellagic acid-mediated apoptosis of PC3 cells.Conclusions:It is tempting to suggest that consumption of tropical pigmented fruits and vegetables could be an effective strategy to combat prostate cancer. | Arshi Malik Sarah Afaq Mohammad Shahid Kafil Akhtar Abdullah Assiri | 2011 | Asian Pacific Journal of Tropical Medicine2011，4，7： | 18 |

| 6 | Advancing male age differentially alters levels and localization patterns of PLCzeta in sperm and testes from different mouse strains显示文摘Sperm-specific phospholipase C zeta(PLCζ)initiates intracellular calcium(Ca2+)transients which drive a series of concurrent events collectively termed oocyte activation.Numerous investigations have linked abrogation and absence/reduction of PLCζwith forms of male infertility in humans where oocyte activation fails.However,very few studies have examined potential relationships between PLCζand advancing male age,both of which are increasingly considered to be major effectors of male fertility.Initial efforts in humans may be hindered by inherent PLCζvariability within the human population,alongside a lack of sufficient controllable repeats.Herein,utilizing immunoblotting,immunofluorescence,and quantitative reverse transcription PCR(qRT-PCR)we examined for the first time PLCζprotein levels and localization patterns in sperm,and PLCζmRNA levels within testes,from mice at 8 weeks,12 weeks,24 weeks,and 36 weeks of age,from two separate strains of mice,C57BL/6(B6;inbred)and CD1(outbred).Collectively,advancing male age generally diminished levels and variability of PLCζprotein and mRNA in sperm and testes,respectively,when both strains were examined.Furthermore,advancing male age altered the predominant pattern of PLCζlocalization in mouse sperm,with younger mice exhibiting predominantly post-acrosomal,and older mice exhibiting both post-acrosomal and acrosomal populations of PLCζ.However,the specific pattern of such decline in levels of protein and mRNA was strain-specific.Collectively,our results demonstrate a negative relationship between advancing male age and PLCζlevels and localization patterns,indicating that aging male mice from different strains may serve as useful models to investigate PLCζin cases of male infertility and subfertility in humans. | Junaid Kashir Bhavesh V Mistry Maha Adel Gumssani Muhammad Rajab Reema Abu-Dawas Falah AlMohanna Michail Nomikos Celine Jones Raed Abu-Dawud Nadya Al-Yacoub Kevin Coward F Anthony Lai Abdullah M Assiri | 2021 | Asian Journal of Andrology2021，23，2： | 0 |
