DNA methylation patterns and gene expression from amygdala tissue of mature Brahman cows exposed to prenatal stress

Autor: Emilie C. Baker, Audrey L. Earnhardt, Kubra Z. Cilkiz, Haley C. Collins, Brittni P. Littlejohn, Rodolfo C. Cardoso, Noushin Ghaffari, Charles R. Long, Penny K. Riggs, Ronald D. Randel, Thomas H. Welsh, David G. Riley

Publikováno v: Frontiers in Genetics, Vol 13 (2022)

Prenatal stress can alter postnatal performance and temperament of cattle. These phenotypic effects may result from changes in gene expression caused by stress-induced epigenetic alterations. Specifically, shifts in gene expression caused by DNA meth

Autor: Kubra Z. Cilkiz, Emilie C. Baker, Penny K. Riggs, Brittni P. Littlejohn, Charles R. Long, Thomas H. Welsh, Ronald D. Randel, David Greg Riley

Publikováno v: Epigenetics, Vol 16, Iss 5, Pp 519-536 (2021)

Possible phenotypic impairments associated with maternal stress during gestation in beef cattle may be explained by epigenetic effects. This study examined the impact of prenatal transportation stress on DNA methylation of lymphocytes of Brahman cows

Skeletal Muscle Expression of Actinin-3 (ACTN3) in Relation to Feed Efficiency Phenotype of F2Bos indicus - Bos taurus Steers

Autor: Robert N. Vaughn, Kelli J. Kochan, Aline K. Torres, Min Du, David G. Riley, Clare A. Gill, Andy D. Herring, James O. Sanders, Penny K. Riggs

Publikováno v: Frontiers in Genetics, Vol 13 (2022)

In this study, actinin-3 (ACTN3) gene expression was investigated in relation to the feed efficiency phenotype in Bos indicus - Bos taurus crossbred steers. A measure of relative feed efficiency based on residual feed intake relative to predictions f

Inter-Individual Variation in DNA Methylation Patterns across Two Tissues and Leukocytes in Mature Brahman Cattle

Autor: Emilie C. Baker, Audrey E. San, Kubra Z. Cilkiz, Brittni P. Littlejohn, Rodolfo C. Cardoso, Noushin Ghaffari, Charles R. Long, Penny K. Riggs, Ronald D. Randel, Thomas H. Welsh, David G. Riley

Publikováno v: Biology, Vol 12, Iss 2, p 252 (2023)

Quantifying the natural inter-individual variation in DNA methylation patterns is important for identifying its contribution to phenotypic variation, but also for understanding how the environment affects variability, and for incorporation into stati

Considerations for the use of Cre recombinase for conditional gene deletion in the mouse lens

Autor: Phuong T. Lam, Stephanie L. Padula, Thanh V. Hoang, Justin E. Poth, Lin Liu, Chun Liang, Adam S. LeFever, Lindsay M. Wallace, Ruth Ashery-Padan, Penny K. Riggs, Jordan E. Shields, Ohad Shaham, Sheldon Rowan, Nadean L. Brown, Tom Glaser, Michael L. Robinson

Publikováno v: Human Genomics, Vol 13, Iss 1, Pp 1-17 (2019)

Abstract Background Despite a number of different transgenes that can mediate DNA deletion in the developing lens, each has unique features that can make a given transgenic line more or less appropriate for particular studies. The purpose of this wor

Differential Expression of MicroRNAs in Dark-Cutting Meat from Beef Carcasses

Autor: Penny K. Riggs, Dustin A. Therrien, Robert N. Vaughn, Marissa L. Rotenberry, Brian W. Davis, Andy D. Herring, David G. Riley, H. Russell Cross

Publikováno v: Applied Sciences, Vol 12, Iss 7, p 3555 (2022)

“Dark-cutting” meat in beef carcasses can result from conditions such as long-term stress and depleted glycogen stores, but some aspects of the physiological mechanisms that cause dark-cutting phenotypes remain poorly understood. Certain response

Publikováno v: Genetics and Molecular Biology, Vol 37, Iss 3, Pp 518-525 (2014)

Gestation length, birth weight, and weaning weight of F2 Nelore-Angus calves (n = 737) with designed extensive full-sibling and half-sibling relatedness were evaluated for association with 34,957 SNP markers. In analyses of birth weight, random relat
