Circ_0011446 Regulates Intramuscular Adipocyte Differentiation in Goats via the miR-27a-5p/FAM49B Axis.

Intramuscular fat (IMF), or marbling, is a critical indicator of goat meat quality. Non-coding RNAs play a key role in the formation and deposition of IMF in vertebrates by regulating genes involved in its synthesis, degradation, and transport. The competing endogenous RNA (ceRNA) hypothesis identifies circular RNAs (circRNAs) as natural "sponges" for microRNAs (miRNAs).

Functional Identification of Allograft Inflammatory Factor 1-Like Gene in Luning Chicken.

Allograft inflammatory factor-1 (AIF-1) is an inflammation-related protein mainly produced by immune cells, such as monocyte/macrophages and activated T lymphocytes. It is essential for the survival and proinflammatory activity of immune cells. However, the function of AIF-1 in chicken still has not been defined.

Supplementation of cilostazol during in vitro maturation enhances the meiosis and developmental competence of yak oocytes by influencing cAMP content and mRNA expression.

The efficiency of in vitro embryo production remains low compared with that observed in vivo. Recent studies have independently shown that cyclic adenosine monophosphate (cAMP) modulation prior to in vitro maturation (IVM) supplementation improves oocyte developmental competence. In this context, special cAMP modulators have been applied during IVM as promising alternatives to improve this biotechnology.

Cloning and Expression of SFRP5 in Tibetan Chicken and its Relationship with IMF Deposition.

Secreted frizzled related protein 5 (SFRP5), an anti-inflammatory adipokine, is relevant to the adipocyte differentiation. In order to clarify its role in regulating intramuscular fat (IMF) deposition in Tibetan chicken, the full-length sequence of the Tibetan chicken SFRP5 gene was cloned. The relative expression of SFRP5 gene was detected using quantitative RT-PCR in various tissues of 154 days old Tibetan chicken, as well as in breast muscle, thigh muscle, and adipose tissue at different growth stages.

Characterization of a bifunctional O- and N-glucosyltransferase from Vitis vinifera in glucosylating phenolic compounds and 3,4-dichloroaniline in Pichia pastoris and Arabidopsis thaliana.

2,4,5-Trichlorophenol, 2,6-dimethylphenol, 3-methylcatechol, phenol, hydroquinone, catechol, and 3,4-dichloroaniline are present in the environment and are risky to humans and animals because of their wide applications in many industries. In this study, a putative uridine diphosphate glucose-dependent glycosyltransferase from Vitis vinifera (VvUGT72B1) displayed high O-glucosyltransferase or N-glucosyltransferase activity toward all these xenbiotics and was able to enhance the resistance of P. pastoris to them.

Selective Detoxification of Phenols by Pichia pastoris and Arabidopsis thaliana Heterologously Expressing the PtUGT72B1 from Populus trichocarpa.

Phenols are present in the environment and commonly in contact with humans and animals because of their wide applications in many industries. In a previous study, we reported that uridine diphosphate-glucose-dependent glucosyltransferase PtUGT72B1 from Populus trichocarpa has high activity in detoxifying trichlorophenol by conjugating glucose. In this study, more experiments were performed to determine the substrate specificity of PtUGT72B1 towards phenolic compounds.

[The role of 9-cisRA in the regulation of pig preadipocyte differentiation].

RT-PCR,Oil red O staining, Oil red O staining extract and spectrometer were used to study the effect and mechanisms of different concentrations of 9-cis RA (0-10 micromol/L) on the differentiation of pig primary preadipocyte. The results showed that different concentrations of 9-cis RA had different effect on the differentiation of preadipocyte. Low concentrations of 9-cisRA (0-10 nmol/L) could promote the differentiation of preadipocyte and upregulate the expression of RXRalpha, PPARgamma mRNA and the activity of GPDH.
