        MLL4 Regulates the Progression of Non-Small-Cell Lung Cancer by Regulating the PI3K/AKT/SOX2 Axis

        Yang Yang,Rongfang Qiu,Qiaoyou Weng,Ziwei Xu,Jingjing Song,Siyu Zhao,Miaomiao Meng,Dengke Zhang,Chunli Kong,Hailin Wang,Min Xu,Zhongwei Zhao,Jiansong Ji 대한암학회 2023 Cancer Research and Treatment Vol.55 No.3

        Purpose Mixed-lineage leukemia protein 4 (MLL4/KMT2D) is a histone methyltransferase, and its mutation has been reported to be associated with a poor prognosis in many cancers, including lung cancer. We investigated the function of MLL4 in lung carcinogenesis. Materials and Methods RNA sequencing (RNA-seq) in A549 cells transfected with control siRNA or MLL4 siRNA was performed. Also, we used EdU incorporation assay, colony formation assays, growth curve analysis, transwell invasion assays, immunohistochemical staining, and in vivo bioluminescence assay to investigate the function of MLL4 in lung carcinogenesis. Results We found that MLL4 expression was downregulated in non–small cell lung cancer (NSCLC) tissues compared to adjacent normal tissues and tended to decrease with disease stage progression. We analyzed the transcriptomes in control and MLL4- deficient cells using high-throughput RNA deep sequencing (RNA-seq) and identified a cohort of target genes, such as SOX2, ATF1, FOXP4, PIK3IP1, SIRT4, TENT5B, and LFNG, some of which are related to proliferation and metastasis. Our results showed that low expression of MLL4 promotes NSCLC cell proliferation and metastasis and is required for the maintenance of NSCLC stem cell properties. Conclusion Our findings identify an important role of MLL4 in lung carcinogenesis through transcriptional regulation of PIK3IP1, affecting the PI3K/AKT/SOX2 axis, and suggest that MLL4 could be a potential prognostic indicator and target for NSCLC therapy.

        論錢穆對漢代『春秋』學的硏究

        楊兆貴 ( Yang¸ Zhao Gui ),趙殷尙 ( Cho¸ Eun Sang ) 한국중국학회 2021 중국학보 Vol.97 No.-

        錢穆對秦漢史、漢代經學研究飮譽學林, 影響很大。他這兩方面的論著大多已逾半世紀, 在出土文獻日益增多、研究方法多元化等學風下, 他的論著有哪些價值?對當代相關研究有什麼影響?筆者結合他這兩方面的研究, 聚焦他的漢代『春秋』學, 以見他治學、見解之一斑。 要探討他對漢代『春秋』學的看法, 則先簡介他對『春秋』及三傳的看法。他與傳統主張孔子作『春秋』的看法相同, 並從史學肯定『春秋』、『左傳』的史學價值。他認為漢代經學今古文之別是王官學與百家言之殊, 而非文字古今之異。這是他論漢代經今古文最具特色的部分。他撰『孔子與春秋』一文, 著重闡釋『公羊』學的精神, 強調孔子『春秋』以百家言而成為新的王官學。他在不同時期對『公羊』學與董仲舒的評價不同。他認為漢儒多通古今, 因此治『春秋』者多能兼採三傳或兩傳之義、說。他又指出, 『春秋』學與漢代思想尤其是災異說、禪讓說、禮制說有密切的關係。 Prof. Qian Mu has a great influence on the honorary scholars of Qin and Han history and Han dynasty studies. Most of his works in these two areas have been over half a century. With the increasing number of unearthed documents and diversified research methods, what is the value of his works? And what is the impact on contemporary related research? This essay combines his research in these two areas and focuses on his study of Chun Qiu in the Han Dynasty, so as to see his academic research methods and insights. To explore his views on the study of Chun Qiu in the Han Dynasty, the first part of the essay introduces his views on Chun Qiu and the three ‘Zhuan’. He is the same as the traditional view that Confucius wrote Chun Qiu, and affirmed the historical value of Chun Qiu and Zuo Zhuan from his historiography. He believes that the difference between modern and ancient literatures in Han dynasty is the difference between Ancient Official Document and Philosophers, rather than the difference between ancient and modern writing. He wrote the article Confucius and Chun Qiu, focusing on explaining the spirit of school of Gong Yang, emphasizing that Confucius' Chun Qiu became a new official ideology with the philosophical thought in Han China. He had different evaluations of Gong Yang and Dong Zhongshu in different periods. He believes that the Han scholars are mostly integrated with the ancient and modern literatures, so most of them who studied Chun Qiu can adopt the meaning and theories of the three or two ‘Zhuan’ at the same time. He also pointed out that the study of Chun Qiu has a close relationship with the thoughts of the Han Dynasty, especially the theory of catastrophe, concession, and etiquette.

        Power System Sensitivity Analysis for Probabilistic Small Signal Stability Assessment in a Deregulated Environment

        Zhao Yang Dong,Chee Khiang Pang,Pei Zhang 대한전기학회 2005 International Journal of Control, Automation, and Vol.3 No.2

        Deregulations and market practices in power industry have brought great challenges to the system planning area. In particular, they introduce a variety of uncertainties to system planning. New techniques are required to cope with such uncertainties. As a promising approach, probabilistic methods are attracting more and more attentions by system planners. In small signal stability analysis, generation control parameters play an important role in determining the stability margin. The objective of this paper is to investigate power system state matrix sensitivity characteristics with respect to system parameter uncertainties with analytical and numerical approaches and to identify those parameters have great impact on system eigenvalues, therefore, the system stability properties. Those identified parameter variations need to be investigated with priority. The results can be used to help Regional Transmission Organizations (RTOs) and Independent System Operators (ISOs) perform planning studies under the open access environment.

      • Robust MAVE for single-index varying-coefficient models

        Zhao Yang,Yue Lili,Li Gaorong 한국통계학회 2022 Journal of the Korean Statistical Society Vol.51 No.4

        In this paper, a robust, efficient and easily implemented estimation procedure for single-index varying-coefficient models is proposed by combining minimum average variance estimation (MAVE) with exponential squared loss. The merit of the proposed method is robust against outliers or heavy-tailed error distributions while asymptotically efficient as the original MAVE under the normal error case. A practical minorization–maximization algorithm is proposed for implementation. Under some regularity conditions, asymptotic distributions of the resulting estimators are derived. Simulation studies and a real data example are conducted to examine the finite sample performance of the proposed method. Both theoretical and empirical findings confirm that our proposed method works very well.

        Hypothalamic Norepinephrine Mediates Acupunctural Effects on Hypothalamic-Pituitary-Adrenal Axis During Ethanol Withdrawal

        Zhao, Z.L.,Kim, S.C.,Zhang, J.,Liu, H.F.,Lee, B.H.,Jang, E.Y.,Lee, C.W.,Cho, I.J.,An, W.G.,Yang, C.H.,Kim, Y.W.,Zhao, R.J.,Wu, Y.Y. Elsevier Science B.V., Amsterdam 2016 JOURNAL OF ACUPUNCTURE AND MERIDIAN STUDIES Vol.9 No.1

        A previous study demonstrated that acupuncture at ST36 (Zu-San-Li) attenuates ethanol withdrawal (EW)-induced hyperactivation of the hypothalamic-pituitary-adrenal axis in rats. The current study investigated the involvement of hypothalamic norepinephrine (NE) in that process. Rats were intraperitoneally treated with 3 g/kg/d of ethanol or saline for 28 days. After 24 hours of EW, acupuncture was applied to rats at bilateral ST36 points or at nonacupoints (tail) for 1 minute. A high-performance liquid chromatography analysis showed that EW significantly increased both the NE and the 3-methoxy-4-hydroxy-phenylglycol (MHPG) levels in the hypothalamic paraventricular nucleus (PVN). Western blot analysis also revealed that EW markedly elevated the phosphorylation rates of tyrosine hydroxylase (TH), but spared TH protein expression in the PVN. However, acupuncture at ST36, but not at nonacupoints, greatly inhibited the increase in the hypothalamic NE, MHPG, and phosphorylation rates of TH. Additionally, postacupuncture infusion of NE into the PVN significantly attenuated the inhibitory effects of acupuncture at ST36 on the oversecretion of plasma corticosterone during EW. These results suggest that acupuncture at ST36 inhibits EW-induced hyperactivation of the hypothalamic NEergic system to produce therapeutic effects on the hypothalamic-pituitary-adrenal axis.

        OPTIMAL PORTFOLIO STRATEGIES WITH A LIABILITY AND RANDOM RISK: THE CASE OF DIFFERENT LENDING AND BORROWING RATES

        Yang, Zhao-Jun,Huang, Li-Hong 한국전산응용수학회 2004 Journal of applied mathematics & informatics Vol.15 No.1

        This paper deals with two problems of optimal portfolio strategies in continuous time. The first one studies the optimal behavior of a firm who is forced to withdraw funds continuously at a fixed rate per unit time. The second one considers a firm that is faced with an uncontrollable stochastic cash flow, or random risk process. We assume the firm's income can be obtained only from the investment in two assets: a risky asset (e.g., stock) and a riskless asset (e.g., bond). Therefore, the firm's wealth follows a stochastic process. When the wealth is lower than certain legal level, the firm goes bankrupt. Thus how to invest is the fundamental problem of the firm in order to avoid bankruptcy. Under the case of different lending and borrowing rates, we obtain the optimal portfolio strategies for some reasonable objective functions that are the piecewise linear functions of the firm's current wealth and present some interesting proofs for the conclusions. The optimal policies are easy to be operated for any relevant investor.

        Spreading Shape and Area Regulate the Osteogenesis of Mesenchymal Stem Cells

        Yang Zhao,Qing Sun,Shurong Wang,Bo Huo 한국조직공학과 재생의학회 2019 조직공학과 재생의학 Vol.16 No.6

        BACKGROUND: Mesenchymal stem cells (MSCs) have strong self-renewal ability and multiple differentiation potential. Some studies confirmed that spreading shape and area of single MSCs influence cell differentiation, but few studies focused on the effect of the circularity of cell shape on the osteogenic differentiation of MSCs with a confined area during osteogenic process. METHODS: In the present study, MSCs were seeded on a micropatterned island with a spreading area lower than that of a freely spreading area. The patterns had circularities of 1.0 or 0.4, respectively, and areas of 314, 628, or 1256 lm2. After the cells were grown on a micropatterned surface for 1 or 3 days, cell apoptosis and F-actin were stained and analyzed. In addition, the expression of b-catenin and three osteogenic differentiation markers were immunofluorescently stained and analyzed, respectively. RESULTS: Of these MSCs, the ones with star-like shapes and large areas promoted the expression of osteogenic differentiation markers and the survival of cells. The expression of F-actin and its cytosolic distribution or orientation also correlated with the spreading shape and area. When actin polymerization was inhibited by cytochalasin D, the shaperegulated differentiation and apoptosis of MSCs with the confined spreading area were abolished. CONCLUSION: This study demonstrated that a spreading shape of low circularity and a larger spreading area are beneficial to the survival and osteogenic differentiation of individual MSCs, which may be regulated through the cytosolic expression and distribution of F-actin.

      • Inotodiol Inhabits Proliferation and Induces Apoptosis through Modulating Expression of cyclinE, p27, bcl-2, and bax in Human Cervical Cancer HeLa Cells

        Zhao, Li-Wei,Zhong, Xiu-Hong,Yang, Shu-Yan,Zhang, Yi-Zhong,Yang, Ning-Jiang Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.7

        Inonotus obliquus is a medicinal mushroom that has been used as an effective agent to treat various diseases such as diabetes, tuberculosis and cancer. Inotodiol, an included triterpenoid shows significant anti-tumor effect. However, the mechanisms have not been well documented. In this study, we aimed to explore the effect of inotodiol on proliferation and apoptosis in human cervical cancer HeLa cells and investigated the underlying molecular mechanisms. HeLa cells were treated with different concentrations of inotodiol. The MTT assay was used to evaluate cell proliferating ability, flow cytometry (FCM) was employed for cell cycle analysis and cell apoptosis, while expression of cyclinE, p27, bcl-2 and bax was detected by immunocytochemistry. Proliferation of HeLa cells was inhibited by inotodiolin a dose-dependent manner at 24h (r=0.9999, p<0.01). A sub-$G_1$ peak (apoptotic cells) of HeLa cells was detected after treatment and the apoptosis rate with the concentration and longer incubation time (r=1.0, p<0.01), while the percentage of cells in S phase and $G_2$/M phase decreased significantly. Immunocytochemistry assay showed that the expression of cyclin E and bcl-2 in the treated cells significantly decreased, while the expression of p27 and bax obviously increased, compared with the control group (p<0.05). The results of our research indicate that inotodiol isolated from Inonotus obliquus inhibited the proliferation of HeLa cells and induced apoptosis in vitro. The mechanisms may be related to promoting apoptosis through increasing the expression of bax and cutting bcl-2 and affecting the cell cycle by down-regulation the expression of cyclin E and up-regulation of p27. The results further indicate the potential value of inotodiol for treatment of human cervical cancer.
