| 1 | Tumor cyclooxygenase-2 levels correlate with tumor invasiveness in human hepatocellular carcinoma显示文摘AIM: Recent studies suggested that cyclooxygenase-2(COX-2) enhances tumor angiogenesis via upregulationof vascular endothelial growth factor (VEGF). AlthoughCOX-2 expression has been demonstrated in hepatocellularcarcinoma (HCC), the significance of COX-2 in progressionof HCC remains unclear. This study evaluated the clinico-pathological correlation of COX-2 level and its relationshipwith VEGF level in HCC.METHODS: Fresh tumor tissues were obtained from 100patients who underwent resection of HCC. COX-2 proteinexpression was examined by immunohistochemistry, andquantitatively by an enzyme immunometric assay (EIA)of tumor cytosolic COX-2 levels. Tumor cytosolic VEGFlevels were measured by an ELISA.RESULTS: Immunostaining showed expression of COX-2in tumor cells. Tumor cytosolic COX-2 levels correlatedwith VEGF levels (r = 0.469, P<0.001). Correlation withclinicopathological features showed significantly highertumor cytosolic COX-2 levels in the presence of multipletumors (P = 0.027), venous invasion (P = 0.030),microsatellite lesions (P = 0.037) and advanced tumorstage (P = 0.008). Higher tumor cytosolic COX-2 levelswere associated with worse patient survival.CONCLUSION: This study shows that elevated tumorCOX-2 levels correlate with elevated VEGF levels andinvasiveness in HCC, suggesting that COX-2 plays a significantrole in the progression of HCC. | TerenceC.Tang RonnieT.Poon CeciliaP.Lau Danxie SheungTatFan | 2005 | World Journal of Gastroenterology2005,11,13: | 37 |
| 2 | Oncogenic role of clusterin overexpression in multistage colorectal tumorigenesis and progression显示文摘AIM: To investigate the expression pattern of clusterin in colorectal adenoma-carcinoma-metastasis series, and to explore the potential role of dusterin in multistage colorectal tumorigenesis and progression.METHOD:S: A colorectal carcinoma (CRC)-tissue microarray (TMA), which contained 85 advanced CRCs including 43 cases of Dukes B, 21 of Dukes C and 21 of Dukes D tumors, were used for assessing the expression of clusterin (clone 41D) and tumor cell apoptotic index (AI) by immunohistochemistry and TUNEL assay, respectively. Moreover the potential correlation of dusterin expression with the patient'sclinical-pathological features were also examined. RESULTS: The positive staining of clusterin in different colorectal tissues was primarily a cytoplasmic pattern. Cytoplasmic overexpression of clusterin was detected in none of the normal coloredal mucosa, 17% of the adenomas, 46% of the primary CRCs, and 57% of the CRC metastatic lesions. In addition, a significant positive correlation between overexpression of clusterin and advanced clinical (Dukes) stage was observed (P<0.01). Overexpression of cytoplasmic clusterin in CRCs was inversely correlated with tumor apoptotic index (P<0.01), indicating the anti apoptotic function of cytoplasmic clusterin in CRCs.CONCLUSION: These data suggests that overexpression of cytoplasmic dustin might be involved in the tumorigenesis and/or progression of CRCs. The anti-apoptotic function of cytoplasmic dusterin may be responsible, at least in part, for the development and biologically aggressive behavior of CRC. | DanXie JonathanS.T.Sham Wei-FenZeng Li-HongChe MengZhang Hui-XiWu Han-LiangLin Jian-MingWen SzeHangLau LiangHu Xin-YuanGuan | 2005 | World Journal of Gastroenterology2005,11,21: | 4 |

| 15 | α-myosin heavy chain lactylation maintains sarcomeric structure and function and alleviates the development of heart failure显示文摘The sarcomeric interaction ofα-myosin heavy chain(α-MHC)with Titin is vital for cardiac structure and contraction.However,the mechanism regulating this interaction in normal and failing hearts remains unknown.Lactate is a crucial energy substrate of the heart.Here,we identify thatα-MHC undergoes lactylation on lysine 1897 to regulate the interaction ofα-MHC with Titin.We observed a reduction ofα-MHC K1897 lactylation in mice and patients with heart failure.Loss of K1897 lactylation inα-MHC K1897R knock-in mice reducesα-MHC–Titin interaction and leads to impaired cardiac structure and function.Furthermore,we identified that p300 and Sirtuin 1 act as the acyltransferase and delactylase ofα-MHC,respectively.Decreasing lactate production by chemical or genetic manipulation reducesα-MHC lactylation,impairsα-MHC–Titin interaction and worsens heart failure.By contrast,upregulation of the lactate concentration by administering sodium lactate or inhibiting the pivotal lactate transporter in cardiomyocytes can promoteα-MHC K1897 lactylation andα-MHC–Titin interaction,thereby alleviating heart failure.In conclusion,α-MHC lactylation is dynamically regulated and an important determinant of overall cardiac structure and function.Excessive lactate efflux and consumption by cardiomyocytes may decrease the intracellular lactate level,which is the main cause of reducedα-MHC K1897 lactylation during myocardial injury.Our study reveals that cardiac metabolism directly modulates the sarcomeric structure and function through lactate-dependent modification ofα-MHC. | Naijin Zhang Ying Zhang Jiaqi Xu Pengbo Wang Boquan Wu Saien Lu Xinxin Lu Shilong You Xinyue Huang Mohan Li Yuanming Zou Mengke Liu Yuanhui Zhao Guozhe Sun Wenbin Wang Danxi Geng Jingwei Liu Liu Cao Yingxian Sun | 2023 | Cell Research2023,33,9: | 0 |
