Granulosa cell proliferation in the gilt ovary associated with ovarian status and porcine reproductive and respiratory syndrome virus detection

Abstract The aims of the present study were to quantify the number of follicles and determine granulosa cell proliferation in the ovaries of gilts in relation to ovarian status and porcine reproductive and respiratory syndrome (PRRS) virus infection. Ovarian tissues were obtained from 37 Landrace × Yorkshire crossbred gilts aged 270.7 ± 24.5 days and weighing 144.5 ± 15.0 kg (27 cycling and 10 prepubertal gilts). PRRS virus was detected using immunohistochemistry, and the ovaries were classified as negative (n = 17) or positive (n = 20) to PRRS virus. Granulosa cell proliferation was determined by proliferating cell nuclear antigen (PCNA) immunostaining. The proportion of PCNA-expressing granulosa cells in pre-antral (n = 197) and antral follicles (n = 76) was determined using Image-Pro® Plus software. The number of follicles in ovarian tissue containing PRRS virus did not differ significantly compared with those without PRRS virus. Granulosa cell proliferation was influenced by the type of follicle (P

Discussion Bardet-Biedl syndrome (BBS) is a rare disorder. It is usually considered an autosomal recessive disorder but there is significant intra-familial variability. There are multiple genes (~20 currently) involved and it is believed that the phenotypic variability is due to “…differences in the total mutational load across different BBS associated genes….” It is a ciliopathy where mutation changes in proteins in the cilias causes problems in the cilia’s functioning particularly signaling. Cilia are important in signaling to maintain tissue and cellular homeostasis. Obviously screening o...

Semin Reprod Med DOI: 10.1055/s-0039-1694027Male infertility is a condition that affects approximately 50% of infertile couples and about 30% of those couples have only male factor infertility identified. There has been speculation that male military service members may have an even greater lifetime prevalence of infertility as compared to the general population, but very few scientific publications focus on male factor infertility in the military population specifically. This review will discuss many of the unique considerations regarding male infertility in the military and highlight future opportunities for research. Th...

ConclusionThe result clearly indicates the significance of 19p13.3 duplication in infertile men with severe testicular phenotypes. The present study underlines the utility and significance of whole genomic analysis in the cases of male infertility which goes undiagnosed due to limitations in the conventional cytogenetic techniques and for identifying genes that are essential for spermatogenesis.
