Abstract
The Xinjiang brown cattle, Red steppe cattle, and Yunling cattle are indigenous cultivated cattle breeds in Chinese frontier provinces, and they produce high-grade beef and milk products, however, their genetic diversity in many important genes related to excellent meat and milk production is still unknown. Our previous studies have found that several candidate genes (e.g., SREBP1c and PAX7) were associated with bovine economically important phenotypic traits, but none has been reported in the above-mentioned three cattle breeds. Since the InDel (insertion/deletion) marker becomes a useful tool applied in the animal molecular breeding, herein, we firstly found that the InDel variations of seven candidate genes in these cattle. Results showed that the genotypic and allelic distributions of these seven genes were remarkably different among these three cattle (p < 0.05 or p < 0.01). Furthermore, the InDel variations of SREBP1c and PAX7 genes were significantly associated with eight phenotypic traits in Xinjiang brown cattle (p < 0.05 or p < 0.01), respectively, suggesting that they can become the useful DNA markers.

Silva-Veiga FM, Rachid TL, de Oliveira L, Graus-Nunes F, Mandarim-de-Lacerda CA, Souza-Mello V. GW0742 (PPAR-beta agonist) attenuates hepatic endoplasmic reticulum stress by improving hepatic energy metabolism in high-fat diet fed mice. Mol Cell Endocrinol 2018; 474:227-237. [PMID: 29580823 DOI: 10.1016/j.mce.2018.03.013] [Citation(s) in RCA: 22] [Impact Index Per Article: 3.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/21/2017] [Revised: 03/10/2018] [Accepted: 03/22/2018] [Indexed: 02/07/2023]
Abstract
Endoplasmic reticulum (ER) stress and hepatic steatosis are intertwined with insulin resistance. PPARs are at the crossroads of these pathways. This study aimed to investigate the effects of GW0742 (PPAR-beta agonist) on hepatic energy metabolism and ER stress in a murine diet-induced obesity model. HF diet caused overweight, hyperinsulinemia, hepatic inflammation (increased NF-kB, TNF-alpha, and IL-6 protein expression) and favored hepatic lipogenesis, leading to ER stress, with ultrastructural and molecular alterations, ending up in proapoptotic stimulus. GW0742 rescued the overweight and the glucose tolerance, tackled hepatic inflammation and favored hepatic beta-oxidation over lipogenesis. These results comply with ER ultrastructure improvement, reducing ER stress and apoptosis in treated animals. Our results indicate that the PPAR-beta/delta activation alleviated the ER stress by improving the insulin sensitivity and maximizing the hepatic energy metabolism with a shift towards beta-oxidation. PPAR-beta/delta activation could be an essential tool to avoid the NAFLD progression and other obesity constraints.
