Identification and characterization of circRNAs related to meat quality during embryonic development of the longissimus dorsi muscle in two pig breeds. Front Genet 2022; 13:1019687. [PMID: 36457752 PMCID: PMC9705349 DOI: 10.3389/fgene.2022.1019687] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2022] [Accepted: 10/27/2022] [Indexed: 11/26/2023] Open
Abstract
Meat quality, an important economic trait, is regulated by many factors, especially by genetic factors, including coding genes, miRNAs, and lncRNAs. Recent studies have elucidated that circRNAs also play a key role in muscle development and lipid deposition. However, the functions and regulatory mechanisms of circRNAs in meat quality remain mostly unknown. The circRNA expression profiles between Huainan pigs (Chinese indigenous pigs, fat-type, Huainan HN) and Large White pigs (Western commercial pigs, lean-type, LW) in the longissimus dorsi (LD) muscle at 38, 58, and 78 days post conception (dpc) were compared by sequencing. In total, 39,887 circRNAs were identified in 18 samples, and 60, 78, and 86 differentially expressed circRNAs (DECs) were found at the three stages mentioned above between these two breeds. The parent genes of DECs were enriched in myogenesis, proliferation, adipogenesis and muscle fiber-type transition. The circRNA-miRNA interaction networks included 38 DECs and 47 miRNAs, and these miRNAs were involved in muscle development and lipid metabolism. Two shared DECs (circ_0030593 and circ_0032760) of these three stages were selected, their head-to-tail junction sites were validated by Sanger sequencing, and RT‒qPCR results suggested that these two DECs might be involved in intramuscular fat deposition. These findings provide a basis for understanding the role of circRNAs in meat quality.

Protective effects of Avena sativa against oxidative stress-induced kidney damage resulting from an estrogen deficiency in ovariectomized Swiss mice model. J Food Biochem 2020; 44:e13205. [PMID: 32249978 DOI: 10.1111/jfbc.13205] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/17/2019] [Revised: 12/19/2019] [Accepted: 01/13/2020] [Indexed: 12/12/2022]
Abstract
The aim of this study was to evaluate the antioxidant capacity of Avena sativa and to confirm its protective effects on estrogen deficiency in ovariectomized mice (OVX) model. Animals were treated during 21 and 60 days as follows: negative control, positive control treated with oat, ovariectomized, and ovariectomized receiving hormonal or oat treatments, respectively. 21 days post-surgery, our results showed that ovariectomy increases weight gain and urea level in plasma. After 60 days of treatment, OVX showed a gain in weight, high increases in relative kidney weight, plasmatic creatinine, glutathione peroxidase (GPX) activity, and protein oxidation as shown by elevated protein carbonyl (PCO) and advanced oxidation protein products (AOPP) levels. On the other side, a decrease was detected in catalase activity. Meanwhile, no significant changes in urea level, lipid peroxidation, SOD and GSH activity were detected. Conversely, supplementation with oat reduced weight gain, as well as oxidative stress and oxidation protein in the kidney of OVX mice. PRACTICAL APPLICATIONS: In our study, we removed the two ovaries of adult female mice in order to eliminate the essential source of steroid hormones. Deficiency in these sexual hormones, especially estrogen, leads to several physiological and morphological disturbances that are found in post-menopausal women. The gain in weight and oxidative kidney damages were the main health problems detected in ovariectomized animals. This work explored for the first time the use of oat grains as a safe natural remedy to treat all previous health problems and to avoid carcinogenic effects of the menopausal hormone therapy. Owing to its health benefits, this cereal species has recently gained attention as an important source of antioxidants and fibers. Thanks to these two components, it can be able to restore all indicated disturbances. Therefore, this cereal can be very useful in the prevention of obesity and kidney oxidative damage occurring during menopause.

Association of single nucleotide polymorphisms in fat metabolism candidate genes with fatty acid profiles of muscle and subcutaneous fat in heavy pigs. Meat Sci 2018; 139:220-227.

Abstract
Dietary and organoleptic qualities of pork products are largely influenced by the profiles of fatty acids (FAs) of meat and fat. The objective of this work was to investigate the potential associations between FA profile in subcutaneous adipose (back fat and leg fat) and muscular (longissimus dorsi and biceps femoris) tissues in heavy pigs (n = 129, 9-month-old) with single nucleotide polymorphisms (SNPs) in six candidate genes involved in fat metabolism: Stearoyl-CoA desaturase (SCD), Diacylglycerol acyltransferase 1 and 2 (DGAT1 &DGAT2), Microsomal Triglyceride Transfer Protein (MTTP), Fatty Acid Synthase (FASN) and Heart- fatty acid binding protein (H-FABP). Preliminary results suggest a putative association between MTTP, DGAT2 and FASN and the FA content in both fat and meat, whereas between DGAT1, SCD and H-FABP the association was found in adipose tissue only. However, the effect of the analyzed genes, needs to be verified in a larger and better characterized pig population to support the hypothesized associations with FA content.

Abstract
High meat quality is required for dry-cured ham production, which quality depends on meat fat quantity and composition. The aim was to study the polymorphisms of six genes involved in fat metabolism, namely, Stearoyl-CoA desaturase (SCD), Diacylglycerol acyltransferase 1 and 2 (DGAT1 &DGAT2), Microsomal triglyceride transfer protein (MTTP), Fatty acid synthase (FASN) and Heart fatty acid binding protein (H-FABP) in two traditional (Large White or Duroc × (Landrace × Large White)) and two industrial hybrids (Goland and Danbred), which are used for dry-cured ham production. Significant associations of SCD and MTTP were found with carcass weight. DGAT2 was associated with back fat thickness and L* fat colour (objective white colour score). Several genes (DGAT2, MTTP &FASN) were associated with weight loss during salting, first step in dry-cured ham production, affecting final yield. Finally, MTTP was associated with shear force. Our findings suggest that the SCD, DGAT2, MTTP and FASN polymorphisms are associated with quality of heavy pig meat products.
