Abstract

Introduction: To identify novel pathways involved in the pathogenesis of ketosis, an isobaric tag for relative and absolute quantitation/mass spectrometry was used to define differences in protein expression profiles between healthy dairy cows and those with clinical or subclinical ketosis.

Abstract

Copper (Cu) is an important microelement for the maintenance of normal metabolism of dairy cows and a variety of enzymic composition. When Cu deficiency is occurred in dairy cows, it’ll be accompanied by many diseases. The main objective of the present study was to explore the correlation between Cu deficiency and oxidative stress of lactating dairy cows and evaluate early-warning index for Cu deficiency. There were divided into two groups based on serum Cu levels: a Cu deficiency group and a control group. Serum levels of ceruloplasmin (CP), superoxide dismutase (SOD), total antioxidant capacity (T-AOC), glutathione peroxidase (GSH-PX), and Cu were analysed. The results showed that CP levels in the Cu deficiency group were significantly lower than in the control group, while T-AOC levels were significantly higher, but there were no significant differences between SOD and GSH-PX levels. Pearson correlation analysis showed that serum CP levels were very significantly positively correlated with Cu deficiency, while serum T-AOC levels were very significantly negatively correlated and SOD and GSH-PX serum levels showed no correlations. Logistic regression analysis showed that CP was a risk factor for Cu deficiency, ROC analysis showed that CP had diagnostic value for Cu deficiency, with a critical value of 13.7 U/l. Hence, CP and T-AOC levels in lactating cows showed strong correlations to Cu deficiency, indicating that serum CP can be used to predict Cu deficiency.

Abstract

Background and objective: Bone remodeling during orthodontic treatment is achieved by the osteogenesis of human periodontal ligament cells (PDLCs) subjected to mechanical loadings. Transcriptional co‐activator with PDZ‐binding motif (TAZ) mediates bone remodeling in response to extracellular mechanical signals. This study aims to investigate the role of TAZ in osteogenesis of PDLCs under tensile strain. Materials and methods: A uniaxial cyclic tensile stress (CTS) at 12% elongation and 6 cycles/min (5 s on and 5 s off) was applied to PDLCs. The osteogenic differentiation was determined by the protein and gene expressions of osteogenic markers using qRT‐PCR and Western blot, respectively, and further by alkaline phosphatase (ALP) activity and Alizarin Red S staining. The interaction of TAZ with core‐binding factor α1 (Cbfα1) was examined by co‐immunoprecipitation. The immunofluorescence histochemistry was used to examine the nucleus aggregation of TAZ and the reorganization of actin filaments. Moreover, small interfering RNA‐targeting TAZ (TAZsiRNA) was used for TAZ inhibition and Y‐27632 was employed for Ras homologue‐associated coiled‐coil protein kinase (ROCK) signaling blockage. Results: CTS clearly stimulated the nucleus accumulation of TAZ and its interaction with Cbfα1. CTS‐induced osteogenesis in PDLCs was significantly abrogated by the infection with TAZsiRNA, as shown by the decreased stained nodules and protein expressions of Cbfα1, collagen type I, osterix, and osteocalcin, along with the inhibition of β‐catenin signaling. Moreover, ROCK inhibition by Y‐27632 hindered TAZ nucleus aggregation and its binding with Cbfα1, which subsequently lead to the decreased osteoblastic differentiation of PDLCs. Conclusions: Taken together, we propose that TAZ nucleus localization and its interaction with Cbfα1 are essential for the CTS‐induced osteogenic differentiation in PDLCs. And such TAZ activation by CTS could be mediated by ROCK signaling, indicating the pivot role of ROCK‐TAZ pathway for PDLCs differentiation. [ABSTRACT FROM AUTHOR]
