Xin JW, Chai ZX, Zhang CF, Zhang Q, Zhu Y, Cao HW, YangJi C, Chen XY, Jiang H, Zhong JC, Ji QM. Differences in proteomic profiles between yak and three cattle strains provide insights into molecular mechanisms underlying high-altitude adaptation. J Anim Physiol Anim Nutr (Berl) 2021; 106:485-493. [PMID: 34494310 DOI: 10.1111/jpn.13629] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/03/2020] [Revised: 06/25/2021] [Accepted: 06/27/2021] [Indexed: 01/22/2023]
Abstract
Yaks display unique properties of the lung and heart, enabling their adaptation to high-altitude environments, but the underlying molecular mechanisms are still largely unknown. In the present study, the proteome differences in lung and heart tissues were compared between yak (Bos grunniens) and three cattle strains (Bos taurus, Holstein, Sanjiang and Tibetan cattle) using the sequential window acquisition of all theoretical mass spectra/data-independent acquisition (SWATH/DIA) proteomic method. In total, 51,755 peptides and 7215 proteins were identified. In the lung tissue, there were 162, 310 and 118 differential abundance proteins (DAPs) in Tibetan, Holstein and Sanjiang cattle compared to yak respectively. In the heart tissue, there were 71, 57 and 78 DAPs in Tibetan, Holstein and Sanjiang cattle compared to yak respectively. The Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that the DAPs were enriched for the retinol metabolism and toll-like receptor categories in lung tissue. The changes in these two pathways may regulate hypoxia-induced factor and immune function in yaks. Moreover, DAPs in heart tissues were enriched for cardiac muscle contraction, Huntington's disease, chemical carcinogenesis and drug metabolism-cytochrome P450. Further exploration indicated that yaks may alter cardiac function through regulation of type 2 ryanodine receptor (RyR2) and Ca2+ -release channels. The present results are useful to further develop an understanding of the mechanisms underlying adaptation of animals to high-altitude conditions.

All-trans retinoic acid preconditioning enhances proliferation, angiogenesis and migration of mesenchymal stem cell in vitro and enhances wound repair in vivo. Cell Prolif 2017; 50:e12315. [PMID: 27862498 PMCID: PMC6529123 DOI: 10.1111/cpr.12315] [Citation(s) in RCA: 50] [Impact Index Per Article: 7.1] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/04/2016] [Accepted: 10/10/2016] [Indexed: 01/01/2023] Open
Abstract
OBJECTIVES Stem cell therapy is considered to be a suitable alternative in treatment of a number of diseases. However, there are challenges in their clinical application in cell therapy, such as to reduce survival and loss of transplanted stem cells. It seems that chemical and pharmacological preconditioning enhances their therapeutic efficacy. In this study, we investigated effects of all-trans retinoic acid (ATRA) on survival, angiogenesis and migration of mesenchymal stem cells (MSCs) in vitro and in a wound-healing model. MATERIALS AND METHODS MSCs were treated with a variety of concentrations of ATRA, and mRNA expression of cyclo-oxygenase-2 (COX-2), hypoxia-inducible factor-1 (HIF-1), C-X-C chemokine receptor type 4 (CXCR4), C-C chemokine receptor type 2 (CCR2), vascular endothelial growth factor (VEGF), angiopoietin-2 (Ang-2) and Ang-4 were examined by qRT-PCR. Prostaglandin E2 (PGE2) levels were measured using an ELISA kit and MSC angiogenic potential was evaluated using three-dimensional tube formation assay. Finally, benefit of ATRA-treated MSCs in wound healing was determined with a rat excisional wound model. RESULTS In ATRA-treated MSCs, expressions of COX-2, HIF-1, CXCR4, CCR2, VEGF, Ang-2 and Ang-4 increased compared to control groups. Overexpression of the related genes was reversed by celecoxib, a selective COX-2 inhibitor. Tube formation and in vivo wound healing of ATRA-treated MSCs were also significantly enhanced compared to untreated MSCs. CONCLUSION Pre-conditioning of MSCs with ATRA increased efficacy of cell therapy by activation of survival signalling pathways, trophic factors and release of pro-angiogenic molecules.

Torabi B, Shemirani F. A new approach to highly sensitive determination of retinoic acid isomers by preconcentration with CdSe quantum dots. Talanta 2014; 120:34-9. [PMID: 24468339 DOI: 10.1016/j.talanta.2013.11.034] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/06/2013] [Revised: 11/12/2013] [Accepted: 11/13/2013] [Indexed: 11/24/2022]
Abstract
Unusual amounts of retinoic acid (RA) isomers play an important role in abnormal morphological development of mammals; such as rat embryos. Each isomer of RA has a unique function in first steps of embryonic life. In the current study, a new method for preconcentration and simultaneous determination of all-trans retinoic acid, 13-cis retinoic acid, 9-cis retinoic acid and 9,13-di-cis retinoic acid in rat whole rudimentary embryo culture (RWEC) has been developed. RA isomers were extracted from samples by conjugation to appropriate amount of surface modified CdSe quantum dots (QDs) prior to HPLC/UV determination. In order to quickly release of the analytes with unchanged form, separated RA-QD conjugation were irradiated by intensive near infrared wavelength (NIR). Low energy NIR irradiation results in maintaining the primary forms of RA isomers during the release. The conjugation and release mechanisms were described and experimental parameters were investigated in detail. Under optimized conditions, the method was linear in the range of 0.040-34.600 pmol g(-1) for all-trans RA (R(2)=0.9996), 0.070-34.200 pmol g(-1) for 13-cis RA (R(2)=0.9992), 0.050-35.300 pmol g(-1) for 9,13-di-cis RA (R(2)=0.9998) and 0.050-32.900 pmol g(-1) for 9-cis RA (R(2)=0.9990). The present method can be useful for retinoic acid monitoring in clinical studies.
