Rational modification of Corynebacterium glutamicum dihydrodipicolinate reductase to switch the nucleotide-cofactor specificity for increasing l-lysine production.
Biotechnol Bioeng 2018 Mar 25. Epub 2018 Mar 25.Jian-Zhong Xu, Han-Kun Yang, Li-Ming Liu, Ying-Yu Wang, Wei-Guo Zhangl-lysine is an important amino acid in animals and humans and NADPH is a vital cofactor for maximizing the efficiency of l-lysine fermentation. Dihydrodipicolinate reductase (DHDPR), an NAD(P)H-dependent enzyme, shows a variance in nucleotide-cofactor affinity in bacteria. In this study, we rationally engineered Corynebacterium glutamicum DHDPR (CgDHDPR) to switch its nucleotide-cofactor specificity resulting in an increase in final titer (from 82.

Crit Rev Biotechnol 2018 Feb 25:1-16. Epub 2018 Feb 25.Jian-Zhong Xu, Han-Kun Yang, Wei-Guo ZhangReduced nicotinamide adenine nucleotide phosphate (NADPH), which is one of the key cofactors in the metabolic network, plays an important role in the biochemical reactions, and physiological function of amino acid-producing strains. The manipulation of NADPH availability and form is an efficient and easy method of redirecting the carbon flux to the amino acid biosynthesis in industrial strains. In this review, we survey the metabolic mode of NADPH.

Epub 2016 Aug 16.Fang Liu, Witold Pedrycz, Wei-Guo ZhangThe relative importance of alternatives expressed in terms of interval numbers in the fuzzy analytic hierarchy process aims to capture the uncertainty experienced by decision makers (DMs) when making a series of comparisons. Under the assumption of full rationality, the judgements of DMs in the typical analytic hierarchy process could be consistent. However, since the uncertainty in articulating the opinions of DMs is unavoidable, the interval number judgements are associated with the limited rationality.

Potential role of 20S proteasome in maintaining stem cell integrity of human bone marrow stromal cells in prolonged culture expansion.
Biochem Biophys Res Commun 2012 May 30;422(1):121-7. Epub 2012 Apr 30.Li Lu, Hui-Fang Song, Wei-Guo Zhang, Xue-Qin Liu, Qian Zhu, Xiao-Long Cheng, Gui-Jiao Yang, Ang Li, Zhi-Cheng XiaoHuman bone marrow stromal cells (hBMSCs) could be used in clinics as precursors of multiple cell lineages following proper induction. Such application is impeded by their characteristically short lifespan, together with the increasing loss of proliferation capability and progressive reduction of differentiation potential after the prolonged culture expansion. In the current study, we addressed the possible role of 20S proteasomes in this process.

Improvement of polygalacturonase production at high temperature by mixed culture of Aspergillus niger and Saccharomyces cerevisiae.
Bioresour Technol 2011 Nov 28;102(21):10085-8. Epub 2011 Aug 28.Jie-Min Zhou, Xiang-Yang Ge, Wei-Guo ZhangCatabolic repression in the synthesis of inducible enzymes by glucose, fructose, and intermediates of the glycolytic cycle has been observed in many microorganisms. In order to enhance the polygalacturonase (PG) production of Aspergillus niger GJ-2, Saccharomyces cerevisiae J-1 was inoculated to the medium at 12h of culture, which resulted in a significant improvement of PG production. It was also found that maximum PG activity of 512.

[Medium-term therapeutic evaluation of an uncemented femoral component].
Zhongguo Gu Shang 2011 Jun;24(6):451-5Jian-guo Zhen, Wei-guo ZhangTo study the clinical and radiographic results of tatal hip arthroplasty (THA) with an uncemented femoral component after 6 to 10 years follow-up, and to investigate factors effecting their efficacy.
From January 2000 to December 2003, 58 patients were treated with primary total hip arthroplasty. Among the patients, 27 patients were male and 31 patients were female, ranging in age from 25 to 73 years, with an average of 56 years.

Heparin-chitosan-coated acellular bone matrix enhances perfusion of blood and vascularization in bone tissue engineering scaffolds.
Tissue Eng Part A 2011 Oct 20;17(19-20):2369-78. Epub 2011 Jun 20.Xin-jun Sun, Wei Peng, Zai-liang Yang, Ming-liang Ren, Shi-chang Zhang, Wei-guo Zhang, Lian-yang Zhang, Kai Xiao, Zheng-guo Wang, Bo Zhang, Jin WangCurrently, the main hurdle in the tissue engineering field is how to provide sufficient blood supply to grafted tissue substitutes in the early post-transplanted period. For three-dimensional, cell-dense, thick tissues to survive after transplantation, treatments are required for hypoxia, nutrient insufficiency, and the accumulation of waste products. In this study, a biomacromolecular layer-by-layer coating process of chitosan/heparin onto a decellularized extracellular bone matrix was designed to accelerate the blood perfusion and re-endothelialization process.

[Influence of estradiol on tryptophan hydroxylase and 5-hydroxytryptamine content in raphe nuclei of rats under forced swimming stress].
Zhonghua Yi Xue Za Zhi 2010 Jul;90(27):1929-32Fu-zhong Yang, Yan Wu, Wei-guo Zhang, Yi-yun Cai, Shen-xun ShiTo investigate the effect of estradiol (E2) on tryptophan hydroxylase (TPH) and 5-hydroxytryptamine (5-HT) content in raphe nuclei of rats under forced swimming stress and explore the role of estrogen and stress in disease mechanism of depression in women.
At Week 3 post-ovariectomy, 35 ovariectomized (OVX) female SD rats were randomly divided into 5 groups (n = 7): non-stress group, control group, estradiol (E2) group and fluoxetine (FLX) group and E2 plus FLX group. Animals were administered with different drugs for 2 weeks.

Improvement of L-lactic acid production by osmotic-tolerant mutant of Lactobacillus casei at high temperature.
Appl Microbiol Biotechnol 2011 Jan 21;89(1):73-8. Epub 2010 Sep 21.Xiang-Yang Ge, Jian Yuan, Hao Qin, Wei-Guo ZhangL-Lactic acid production by Lactobacillus casei was used as a model to study the mechanism of substrate inhibition and the strategy for enhancing L-lactic acid production. It was found that the concentration of cell growth and L-lactate decreased with the increase of glucose concentration and fermentation temperature. To enhance the osmotic stress resistance of the strain at high temperature, a mutant G-03 was screened and selected with 360 g/L glucose at 45°C as the selective criterion.
