Beef cattle that respond differently to fescue toxicosis have distinct gastrointestinal tract microbiota

PLOS ONE, 15(7).

By: C. Pickworth n, L. Bell n, W. Greene*, C. Whisnant n & D. Poole n

author keywords: Estrus synchronization; Quality assurance; Beef production; Injection site
MeSH headings : Animals; Cattle / physiology; Dinoprost / administration & dosage; Dinoprost / pharmacology; Drug Administration Schedule; Estrus Detection / instrumentation; Female; Gonadotropin-Releasing Hormone / administration & dosage; Gonadotropin-Releasing Hormone / pharmacology; Insemination, Artificial / veterinary; Pregnancy; Progesterone / pharmacology; Time Factors
TL;DR: Overall, altering the location of the PGF2α injection during ES did not change circulating hormone concentrations at AI or pregnancy rates; therefore, cattle producers should follow Beef Quality Assurance guidelines when administering ES protocols. (via Semantic Scholar)

Comparison of pregnancy rates in beef cattle after a fixedtime Al with once-or twice-used controlled internal drug release devices

THERIOGENOLOGY, 85(3), 447–451.

By: A. Muth-Spurlock n, D. Poole n & C. Whisnant n

author keywords: Controlled internal drug release; Artificial insemination; Estrus synchronization; Beef cattle
MeSH headings : Animals; Cattle / physiology; Dinoprost / administration & dosage; Dinoprost / adverse effects; Drug Delivery Systems / instrumentation; Drug Delivery Systems / veterinary; Estrus Synchronization / methods; Female; Food Quality; Infusion Pumps, Implantable; Injections, Intramuscular / adverse effects; Insemination, Artificial / methods; Insemination, Artificial / veterinary; Pregnancy; Pregnancy Rate; Progesterone / blood; Red Meat
TL;DR: Evidence is provided that although concentration of progesterone is decreased in animals treated with a twice-used CIDR device, there is still a sufficient release of progestersone from the device to effectively synchronize estrus without adversely affecting the fertility of a herd.

Progesterone effects on lymphocytes may be mediated by membrane progesterone receptors

Journal of Reproductive Immunology, 95(1-2), 15–26.

By: K. Ndiaye*, D. Poole*, S. Walusimbi*, M. Cannon*, K. Toyokawa*, S. Maalouf*, J. Dong, P. Thomas, J. Pate*

author keywords: Lymphocytes; Progesterone; mPR; PGRMC1; Corpus luteum
MeSH headings : Animals; Cattle; Cell Membrane / immunology; Cell Membrane / metabolism; Corpus Luteum / cytology; Corpus Luteum / immunology; Corpus Luteum / metabolism; Female; Gene Expression Regulation / drug effects; Gene Expression Regulation / immunology; Interleukin-2 Receptor alpha Subunit / immunology; Interleukin-2 Receptor alpha Subunit / metabolism; Progesterone / immunology; Progesterone / metabolism; Progesterone / pharmacology; RNA, Messenger / biosynthesis; RNA, Messenger / immunology; Receptors, Progesterone / immunology; Receptors, Progesterone / metabolism; T-Lymphocytes / cytology; T-Lymphocytes / immunology; T-Lymphocytes / metabolism
TL;DR: Progesterone induces specific and rapid functional effects on T lymphocytes in the absence of PGR, and a specific, saturable, and single progesterone binding site with a steroid specificity characteristic of mPRs was demonstrated by saturation and competitive binding assays using T lymphocyte membranes.

Microarray analysis of gene expression in granulosal cells from persistent follicles in cattle

Animal Reproduction Science, 104(2-4), 405–413.

By: B. Lingenfelter*, R. Dailey, E. Inskeep, M. Vernon, D. Poole*, J. Rhinehart, J. Yao

author keywords: oocyte; cow; granulosal cells; persistent follicle
MeSH headings : Animals; Cattle / genetics; Cattle / metabolism; Female; Gene Expression Profiling; Granulosa Cells / metabolism; Granulosa Cells / physiology; Oligonucleotide Array Sequence Analysis / veterinary; Ovarian Follicle / cytology; Ovarian Follicle / metabolism; Ovarian Follicle / physiology; RNA, Messenger / biosynthesis; RNA, Messenger / genetics; Reverse Transcriptase Polymerase Chain Reaction / veterinary
TL;DR: Data suggest that aged granulosal cells may have a reduced capacity to provide energy and amino acids to the oocyte, as revealed in a direct comparison microarray experiment using a bovine long oligo array representing approximately 8400 known genes. (via Semantic Scholar)

Changes of maternal transcripts in oocytes from persistent follicles in cattle

Molecular Reproduction and Development, 74(3), 265–272.

By: B. Lingenfelter*, R. Dailey*, E. Inskeep*, M. Vernon*, D. Poole*, J. Rhinehart*, J. Yao*

author keywords: cow; gene expression; embryonic development
MeSH headings : Animals; Cattle; Estrus / metabolism; Female; Oocytes / metabolism; Ovarian Follicle / metabolism; RNA, Messenger / metabolism; Transcription, Genetic
TL;DR: The data indicate that persistence of a follicle leads to altered abundances of mRNA for genes important for regulation of transcription and protein translation in the oocyte, which could compromise development of early embryos in cows that ovulate a persistent follicle.
