In order to investigate the effect of vitamin E and vitamin E nanoliposomes on the expression of the STAR gene in testis and TSPO gene in the ovary of Japanese quail, an experiment using 864 pieces of quail for 10 weeks in a completely randomized design with six treatments, six replications and 24 Breeding quail (16 females and eight males) was performed in each replication. The treatments were fed diets containing different levels of vitamin E (25, 50 and 100 IU per kg of diet) and vitamin E nanoliposomes (25, 50 and 100 IU per kg of diet). The results of this study showed that the effect of the experimental treatments on the expression of TSPO gene in the ovary and STAR gene in the testis was significant (P<0.05). The addition of 50 IU of vitamin E significantly increased TSPO gene expression in the ovary compared to the control treatment (P<0.05). The results also showed that the level of 25 IU nanoliposome of vitamin E increased the expression of TSPO gene in the ovary, which was not significantly different from the control treatment. The use of vitamin E and vitamin E nanoliposome levels significantly decreased the expression of STAR gene in the testis of Japanese quail (P<0.05). According to the results of this study, the addition of 25 IU vitamin E nanoliposomes as well as 50 and 100 IU levels of vitamin E has a significant effect on the expression of TSPO gene in the ovary, which is one of the genes affecting fertility and reproduction.

The objective of this study was to identify known intergenic lncRNAs related to biological pathways of acidosis in Holstein calves using ruminaltissue. Two groups of healthy calves (N=3) and affected by acidosis (N=3) were compared. Paired-end sequencing method was performed using theHiseq2500 illumine platform. Hisat2 software was used to align reads to the bovine reference genome and StringTie software package was used toassemble read files into transcripts. Using next generation sequencing, 1636 genes belonging to known intergenic lncRNAs were identified, of which56 genes showed significant differential expression (P≤0.05). Neighbor genes of known intergenic lncRNAs were determined on bovine genome.Analysis of biological pathways and molecular function showed that five biological pathways were significantly (P≤0.05) enriched. These pathwayswere Apelin signaling pathway, Gap junction, Glucagon signaling pathway, Renin secretion, and AGE-RAGE signaling pathway. Moreover, twomolecular functions including gap junction channel activity, and phosphatidyl inositol phospholipase C activity were significantly (P≤0.05) enriched.Some lncRNAs have different expression in healthy and acidosis samples, and the decreased pH acts as a stimulus to activate some biologicalsignaling pathways. In conclusion, it was indicated that lncRNAs with differential expression between the control group and the group affected byacidosis are associated with pathways related to rumen energy metabolism and signaling. Identified differentially expressed lncRNAs could be used asprognostic in acidosis and biomarkers or promising candidates in animal breeding.
