(Submitter supplied) The R96C mutation in SOCS2 (suppressor of cytokine signaling 2) that leads to greater milk production but also a greater sensitivity to mastitis was identified in Lacaune sheep by Rupp et al, 2015. This mutation leads to a loss of ligand recognition for SOCS2 and thus interferes with JAK/STAT signaling pathway regulation. A mouse model carrying this mutation (SOCS2 R96C KI) was developed to study its effects on mammary gland development and lactation.

(Submitter supplied) Developmental programming is the concept that environmental factors, particularly during foetal life, can alter development, metabolism and physiology of an organism and this can have consequences later in life. There is growing interest in developmental programming in livestock species, particularly effects of maternal pregnancy nutrition, which is easy to manipulate. Recent research, using a sheep model, has shown that milk production in ewe offspring may be susceptible to maternal nutritional programming, such that over nutrition (ad libitum) of the pregnant dam, compared with maintenance nutrition, may impair their first lactation performance and result in the weaning of lighter lambs. more...

(Submitter supplied) The Th-inducing POK (Th-POK, also known as cKrox or ZBTB7B) transcription factor is a key regulator of lineage commitment of immature T cell precursors. It is yet unclear the physiological functions of Th-POK besides helper T cell differentiation. We found that Th-POK is restrictedly expressed in the luminal epithelial cells in the mammary glands. Th-POK is not required for mammary gland development in puberty and alveologenesis in pregnancy. more...

(Submitter supplied) Transcript profiling was performed by Affymetrix microarray analysis and SAGE to characterize changes in gene expression in the bovine mammary gland in response to 4× versus 2× daily milking during the first week of lactation. These changes in gene expression may contribute to the increased milk production observed in response to increased milking frequency. Our results indicate that increased milking frequency alters expression of genes in the mammary gland related to increased extracellular matrix remodeling, neovascularization, metabolism, cell proliferation and apoptosis. more...

(Submitter supplied) Effect of breed in mid lactation Holstein (H) and Montbéliarde (M) cows on mammary glande miRNA profile. Genetic polymorphisms are known to influence milk production and composition. However, genomic mechanisms involved in the genetic regulation of milk component synthesis are not completely understood. MicroRNAs (miRNA) regulate gene expression. The objective of the present study was to compare mammary gland miRNomes of two dairy cow breeds, Holstein and Montbéliarde, with different dairy performances. more...

(Submitter supplied) The role of chromatin in mammary gland development and differentiation has not been defined. Here we have studied the changes in chromatin conformation in the mammary gland during the lactation cycle at milk protein gene loci, whose gene expression marks functional differentiation of the mammary gland.

(Submitter supplied) The purpose of the present study was to provide a comprehensive transcriptome profiling of mammary gland and to find the key differences in the milk production and related traits between Jersey and Kashmiri cattle. Casein and whey protein genes were found to be highly expressed throughout the lactation cycle. Largest differences in DEGs was reported between D15 and D90 with 1805 genes in Kashmiri cattle and between D15 and D250 with 3392 genes in Jersey cattle.

(Submitter supplied) The mammary gland undergoes extensive remodeling between the begin- ning of pregnancy and lactation; this involves cellular processes including cell proliferation, differentiation, and apoptosis, all of which are under the control of numerous regulators. To unravel the role played by miRNA, we describe here 47 new ovine miRNA cloned from mammary gland in early pregnancy displaying strong similari- ties with those already identified in the cow, human, or mouse. more...
