Gene expression profile analysis of testis and ovary of oriental river prawn, Macrobrachium nipponense, reveals candidate reproduction-related genes

H. Qiao, Xiong, Y. W., Jiang, S. F., Fu, H. T., Sun, S. M., Jin, S. B., Gong, Y. S., and Zhang, W. Y., Gene expression profile analysis of testis and ovary of oriental river prawn, Macrobrachium nipponense, reveals candidate reproduction-related genes, vol. 14, pp. 2041-2054, 2015.

This study utilized high-throughput RNA sequencing technology to identify reproduction- and development-related genes of Macrobrachium nipponense by analyzing gene expression profiles of testis and ovary. More than 20 million 1 x 51-bp reads were obtained by Illumina sequencing, generating more than 7.7 and 11.7 million clean reads in the testis and ovary library, respectively. As a result, 10,018 unitags were supposed to be differentially expressed genes (DEGs) between ovary and testis.

Protective effect of proanthocyanidin against oxidative ovarian damage induced by 3-nitropropionic acid in mice

J. Q. Zhang, Xing, B. S., Zhu, C. C., Shen, M., Yu, F. X., and Liu, H. L., Protective effect of proanthocyanidin against oxidative ovarian damage induced by 3-nitropropionic acid in mice, vol. 14, pp. 2484-2494, 2015.

Oxidative stress, which poses a threat to reproductive health, causes many serious female reproductive diseases. In this study, we investigated whether proanthocyanidins (PC) have a protective effect against oxidative stress-induced ovarian damage. Forty female ICR mice were randomized into 4 groups: a control group, a control plus PC group, a 3-nitropropionic acid (3-NPA) group, and a 3-NPA plus PC group. An ovarian oxidative stress model induced by 3-NPA was constructed using female ICR mice.

Differential gene expression in pre-laying and laying period ovaries of Sichuan White geese (Anser cygnoides)

N. Ding, Han, Q., Zhao, X. Z., Li, Q., Li, J., Zhang, H. F., Gao, G. L., Luo, Y., Xie, Y. H., Su, J., and Wang, Q. G., Differential gene expression in pre-laying and laying period ovaries of Sichuan White geese (Anser cygnoides), vol. 14, pp. 6773-6785, 2015.

Geese are an economically important poultry species worldwide. Their superior meat production performance and meat qual­ity make them a popular food. However, they are not bred worldwide because their poor laying capacity increases farming costs. To gain a global view of the genes that are differentially expressed between pre-laying (P) and laying (L) periods and to develop a database for further studies, we performed large-scale transcriptome sequencing of ovarian tissue collected from Anser cygnoides.

Cell proliferation and apoptosis in the fetal and neonatal ovary of guinea pigs

S. Y. Sun, Zhang, W., Han, X., Huang, R. H., and Shi, F. X., Cell proliferation and apoptosis in the fetal and neonatal ovary of guinea pigs, vol. 13, pp. 1570-1578, 2014.

The guinea pig is an excellent animal model for studying reproductive biology of adult humans and most domestic animals. Yet, whether this animal might serve as a good model for embryonic stage investigations and determinations of signals affecting or directing ovary development remains unknown. These questions were addressed by examining morphological evolution and the expression of biomarkers of cell proliferation and apoptosis in the ovaries of fetal and neonatal guinea pigs in the present study.

Evaluation of attenuated Salmonella choleraesuis-mediated inhibin recombinant DNA vaccine in rats

F. M. Hui, Meng, C. L., Guo, N. N., Yang, L. G., Shi, F. X., and Mao, D. G., Evaluation of attenuated Salmonella choleraesuis-mediated inhibin recombinant DNA vaccine in rats, vol. 13, pp. 6113-6125, 2014.

DNA vaccination has been studied intensively as a potential vaccine technology. We evaluated the effect of an attenuated Salmonella choleraesuis-mediated inhibin DNA vaccine in rats. First, 15 rats were treated with different doses of an inhibin vaccine to evaluate vaccine safety. Next, 30 rats were divided into 3 groups and injected intramuscularly with the inhibin vaccine two (T1) or three times (T2) or with control bacteria (Con) at 4-week intervals.

Changes in cyclic GMP level and phosphodiesterase activity during follicular development in the rat ovary

C. Q. Fu, Shi, F. X., Zhang, Z. H., Li, J. R., Huang, X. H., and Wang, Z. C., Changes in cyclic GMP level and phosphodiesterase activity during follicular development in the rat ovary, vol. 13, pp. 5919-5928, 2014.

Guanosine 3',5'-cyclic monophosphate (cGMP), as a second messenger, plays potential roles in ovarian functions. To elucidate the role of phosphodiesterase (PDE) in cGMP signaling during ovarian follicular development, the present study was conducted to investigate ovarian cGMP level and cGMP-PDE activity by radioimmunoassay (RIA) in postnatal rats, immature rats during gonadotropin-primed follicular development, ovulation and luteinization, adult rats during normal estrous cycle, and aged rats that spontaneously developed persistent estrus (PE).
