Bovine granulosa cells of dominant follicles at 60 days postpartum; effect of negative energy balance on transcriptome

ABSTRACT: Granulosa cells of dominant follicles originating from dairy cows with severe negative energy balance (BHBH) or mild negative energy balance (BHBL) were compared. Mild negative energy balance (BHBL) is the reference. Two conditions experiment (BHBH and BHBL); Four pools of 3 biological replicates for each group (total = 12 cows for each group); Two technical replicates per pool (dye-swap).

Expression data from uterine endometrial tissues of Holstein-Friesian cows on days 14-16 after calving

Project description:Most dairy cows suffer uterine microbial contamination postpartum. Persistent endometritis often develops, associated with reduced fertility. We used a model of differential feeding and milking regimes to produce cows in differing negative energy balance (NEB) status in early lactation. We used Affymetrix GeneChipM-CM-^R Bovine Genome Array to investigate the global gene expression underlying negative energy balance and to identify the significantly differentially expressed genes during this process. We investigate the differences of gene expression profiles in uterine endometrial tissues between the cows with mild and severe negative energy balance.

Cumulus cell gene expression associated with pre-ovulatory acquisition of developmental competence in bovine oocytes

Project description:This study investigated the cumulus cell (CC) transcriptomic changes during the oocyte developmental competence acquisition period. Six dairy cows were used for 24 oocyte collections and received FSH twice daily over 3 days, followed by FSH withdrawal for 20, 44, 68 and 92 h in four different oestrous cycles for each of the six cows. Half of the cumulusâoocyte complexes were subjected to in vitro maturation, fertilisation and culture to assess blastocyst rate. The other half of the CC underwent microarray analysis and qRT-PCR.

Transcriptome analysis of Bovine granulosa cells of preovulatory follicles at 30, 60, 90 and 120 days postpartum

Project description:Cows in Negative Energy Balance (NEB) may preferentially divert nutrients away from reproduction, thereby experiencing a period of anovulatory anestrus, delayed ovulation of large follicles and a condition of impaired fertility. To better understand the changes occurring in these large follicles as a function of time post-partum granulosa cells of preovulatory follicles have been collected at different times: 30, 60, 90 and 120 days after calving . An analysis of the transcriptome was performed using a global bovine oligo-array microarray to map the differences in genes expression and cellular functions that occur in the follicular microenvironment during the progressive recovery from NEB condition in dairy cow Four time points experiment: 30, 60, 90 and 120 days. Granulosa cells from the 30, 60 and 90 days compare to the 120 days (reference). Biological replicates: 3 from each time point. One replicate per array.

RNAseq bovine subcutaneous adipose tissue in periparturient stage

Project description:The severity of negative energy balance (NEB) in high-producing dairy cows has a high incidence among health diseases. The periparturient period is crucial for the health status and reproductive performance of dairy cows. During this period, dairy cows experience a transition from a pregnant, non-lactating state to a non-pregnant, lactating state. At the beginning of lactation, the energy needs for milk production are higher than the available energy consumed from feed intake, resulting in a negative energy balance (NEB)]. While in a NEB, cows mobilise their reserves from adipose tissue, resulting in elevated plasma concentrations of non-esterified fatty acids (NEFAs), which are used as a fuel source by peripheral tissues and the mammary gland for milk fat synthesis. Thus, white adipose tissue is one of the main tissue involved in the energy production during this transition period. So the objectives of our study were to dentify mRNA differentially expressed in white adipose before and after calving in dairy cow fed with low (LE) and high (HE) energy diet.

The effect of negative energy balance on bovine blood PMN gene expression

Project description:Our objectives were to compare gene expression profiles in neutrophils (PMN) during a Streptococcus uberis mastitis challenge between lactating cows subjected to feed restriction to induce negative energy balance (NEB; n = 5) and cows fed ad libitum to maintain positive energy balance (PEB; n = 5). The NEB cows were feed-restricted to 60% of calculated net energy for lactation requirements for 7 d, whereas PEB cows were fed the same diet for ad libitum intake. After 5 d of feed restriction, one rear mammary quarter of each cow was inoculated with 5,000 cfu of Streptococcus uberis (strain O140J). Blood PMN were isolated at 24 h post-inoculation from all cows for RNA extraction and microarray analysis. NEB resulted in 94 differentially expressed genes compared with PEB. Of these, 51 genes were down-regulated, including genes involved with antigen presentation (HLADRA and HLAA), respiratory burst (SOD1), and the pro-inflammatory response (TNFA and IRAK-1). The most affected genes up-regulated by NEB (n = 43) included IL1R2 and IL6, toll-like receptors (TLR2 and TLR4), and THY1. Network analysis by Ingenuity Pathway Analysis ® revealed that TNFA was associated with the expression of numerous differentially expressed genes involved with immune response in NEB cows compared with PEB cows. Energy balance alters PMN expression of several genes involved with immune response, which provides new information on transcriptomic mechanisms associated with post-partal NEB and immune response during early lactation.
