Regulation of FAS Ligand Expression by Chemokine Ligand 2 in Human Endometrial Cells
Biol Reprod 2006 75: 203-209. [Abstract] [Full Text] [PDF]  

Summary: Increased FASLG expression by CCL2 induces apoptosis of T-lymphocytes in human endometrium and thus may produce an immunotolerant environment for the survival of ectopic implants.

Multiple Glycolytic Enzymes Are Tightly Bound to the Fibrous Sheath of Mouse Spermatozoa
Biol Reprod 2006 75: 270-278. [Abstract] [Full Text] [PDF]

Differential Endocrine Regulation of Genes Enriched in Initial Segment and Distal Caput of the Mouse Epididymis as Revealed by Genome-Wide Expression Profiling
Biol Reprod 2006 75: 240-251. [Abstract] [Full Text] [PDF] Supplemental Data  

Summary: Expression profiling revealed that factors other than androgens are important for the expression of IS-enriched genes, whereas the expression of caput-enriched genes is typically regulated by androgens.

Transcriptional Regulation of Cyclin D2 by the PKA Pathway and Inducible cAMP Early Repressor in Granulosa Cells
Biol Reprod 2006 75: 279-288. [Abstract] [Full Text] [PDF] Supplemental Figure  

Summary: A single cAMP response element mediates the hormonal regulation of cyclin D2 expression by the PKA pathway and inducible cAMP early repressor in granulosa cells.

Photoperiodic Regulation of Compensatory Testicular Hypertrophy in Hamsters
Biol Reprod 2006 75: 261-269. [Abstract] [Full Text] [PDF]  

Summary: Day length alters the HPG response to hemi-castration; only short days block FSH hypersecretion in juvenile Siberian hamsters and prevent compensatory testicular hypertrophy in both juvenile and adult Siberian hamsters.

Distinct Regulation by Steroids of Messenger RNAs for FSHR and CYP19A1 in Bovine Granulosa Cells
Biol Reprod 2006 75: 217-225. [Abstract] [Full Text] [PDF]  

Summary: Androgen directly stimulated FSHR mRNA and synergized with FSH and estradiol-17beta to increase CYP19A1 mRNA in bovine granulosa cells.

Late but Not Early Gestational Maternal Growth Hormone Treatment Increases Fetal Adiposity in Overnourished Adolescent Sheep
Biol Reprod 2006 75: 231-239. [Abstract] [Full Text] [PDF]  

Summary: Maternal growth hormone treatment during late pregnancy partially alleviates fetal growth restriction, independent of changes in placental size, and has a profound effect on fetal adiposity.

Progesterone Regulation of Preimplantation Conceptus Growth and Galectin 15 (LGALS15) in the Ovine Uterus
Biol Reprod 2006 75: 289-296. [Abstract] [Full Text] [PDF]  

Summary: Exogenous progesterone stimulates preimplantation ovine blastocyst growth and development in association with endometrial LGALS15.

Poor Centrosomal Function of Cat Testicular Spermatozoa Impairs Embryo Development In Vitro after Intracytoplasmic Sperm Injection
Biol Reprod 2006 75: 252-260. [Abstract] [Full Text] [PDF]  

Summary: Compared to those in ejaculated spermatozoa, the centrosomes of cat testicular spermatozoa give rise to poor sperm aster formation, resulting in delayed first cleavage and compromised in vitro embryo development after sperm microinjection.
