Expression data from SKOV3ip1 cells treated with MORAB-003 antibody

ABSTRACT: MORAB-003 significantly upregulated a number of genes involved in autophagic processing, including GABARAPL2, LC3II (MAP1LC3B), ATG3, ATG4B, and BECN1, while expression of the oncogenic factor PIK3C3 was downregulated. We used microarrays to detail the global programme of gene expression underlying growth inhibition of ovarian cancer cells treated with MORAB-003 microarray analysis of SKOV3ip1 cells with and without MORAb-003 treatment was performed under the following conditions: 1) cells plated in folate-free medium (7 days), 2) cells plated in medium with physiological levels of folic acid (2-10 nm) (7 days), 3) cells with physiological levels of folic acid (7 days) and 003 antibody (24 hours), 4) cells with physiologic levels of folic acid (7 days) and control 004 antibody (24 hours); 5) cells with physiological levels of folic acid (7 days) and MORAb003 antibody (24 hours) . For each condition, a single cell growth was carried out and an RNA sample was extracted. Three aliquots from each RNA sample were then hybridized to Affymetrix U133 2 arrays, for a total of 15 arrays. time course 7days and 24 hours

Project description:The fertility of dairy cows is challenged during early lactation and better nutritional strategies need to be developed to address this issue. Combined supplementation of folic acid and vitamin B12 improves energy metabolism in the dairy cow during early lactation. Therefore, the present study was undertaken to explore the effects of this supplement on gene expression in granulosa cells from the dominant follicle during the postpartum period. Multiparous Holstein cows received weekly intramuscular injection of 320 mg folic acid and 10 mg vitamin B12 (treated group) beginning 24 (SD 4) d before calving until 56 d after calving, whereas the control group received saline. The urea plasma concentration was significantly decreased during the pre-calving period, and the concentration of both folate and vitamin B12 were increased in treated animals. Milk production and dry matter intake were not significantly different between the two groups. Plasma concentrations of folates and vitamin B12 were increased in vitamin-treated animals. Daily dry matter intake was not significantly different between the 2 groups before (13.5 kg SE 0.5) and after (23.6 kg SE 0.9) calving. Average energy-corrected milk tended to be greater in vitamin-treated cows, 39.7 (SE 1.4) and 38.1 (SE 1.3) kg/d for treated and control cows, respectively. After calving, average plasma concentration of BHBA tended to be lower in cows injected with the vitamin supplement, 0.47 (SE 0.04) vs. 0.55 (SE 0.03) for treated and control cows, respectively. The ovarian follicle ? 12 mm in diameter was collected by ovarian pick-up after estrus synchronization. Recovered follicular fluid volumes were greater in the vitamin-treated group. A microarray platform was used to investigate the impact of treatment on gene expression of granulosa cells. Lower expression of genes involved in the cell cycle and higher expression of genes associated with granulosa cell differentiation prior to ovulation were observed. Selected candidate genes were analyzed by reverse transcription quantitative polymerase chain reaction. Although the effects of intramuscular injections of folic acid and vitamin B12 on lactational performance and metabolic status of animals were limited, Ingenuity Pathway Analysis of gene expression in granulosa cells suggests a stimulation of cell differentiation in vitamin-treated cows, which may be the result of an increase in LH secretion. Two conditions experiment (Control and Treated). Granulosa cells from the 66h post second PGF2alpha injection. Biological replicates: 3 from each time point. Two technical replicates for each comparison (dye-swap).
