Yi xue ban = Journal of Central South University. Medical sciences OBJECTIVE:To investigate the correlation between eukaryotic translation initiation factor 3, subunit A (eIF3a) and human epididymis protein 4 (HE4) expression and ovarian cancer. METHODS:RT-PCR or immunohistochemistry was used to examine eIF3a and HE4 mRNA or protein expression in ovarian tissues from patients with ovarian cancer (n=181) or benign ovarian tumors, or from the healthy women. RESULTS:There were significant differences in mRNA and protein expression of eIF3a and HE4 among normal ovarian tissues, benign ovarian tumor tissues, and ovarian cancer tissues (P< 0.05). There were significant differences in mRNA expression of eIF3a and HE4 between the normal tissues and the ovarian cancer tissues, or between the benign ovarian tumor tissues and the normal tissues (P< 0.001). The mRNA expression of eIF3a in the normal ovarian tissues was significantly higher than that in the benign ovarian tumor tissues or that in the ovarian cancer tissues. The mRNA expression of HE4 was gradually increased from the normal ovarian tissues, the benign ovarian tumor tissues to the ovarian cancer tissues. The mRNA expression of HE4 in the ovarian cancer tissues was significantly higher than that in the benign ovarian tumor tissues (P< 0.001). Positive expression rates for eIF3a or HE4 protein in normal, benign tumor, and cancer tissues were 0, 66.7%, and 81.0% or 0, 27.8%, and 56.2%, respectively. There were significant differences in positive expression rates of eIF3a protein and HE4 protein between the ovarian tumor tissues and benign ovarian tumor tissues, between the ovarian cancer tissues and the normal ovarian tissues, or between the benign ovarian tumor tissues and the normal ovarian tissues (P< 0.001). The eIF3a protein expression was positively correlated with HE4 protein expression (r=0.575, P< 0.05). CONCLUSION:The expressions of eIF3a and HE4 are associated with ovarian cancer, and extracellular regulated protein kinases may play a role in the interaction between eIF3a and HE4. 10.11817/j.issn.1672-7347.2014.12.004
[TRPM7 and tumor]. Zhao Min,Luo Chenhui,Wang Ying,Wang Jing Zhong nan da xue xue bao. Yi xue ban = Journal of Central South University. Medical sciences The transient receptor potential (TRP) family is a superfamily of cation channels located on the cell membrane. Transient receptor potential melastatin (TRPM) 7, a member of the TRPM subgroup of TRP channels, and was the most representative biofunctional membrane protein. It conducts calcium and monovalent cations to depolarize cells and increase intracellular calcium. It is capable of phosphorylating TRPM7 and other substrates. TRPM7 can mediate sensory transmission, regulate cellular Ca2+ and Mg2+ homeostasis and affect embryonic development. Abnormal expression and/or activity of the TRPM7 channel kinase is involved in a variety of diseases, particularly the development and progression of cancer. TRPM7 channel-kinase is essential for cellular processes, such as proliferation, survival, differentiation, growth, and migration. 10.11817/j.issn.1672-7347.2016.03.017
Better outcomes of modified myeloablative conditioning without antithymocyte globulin versus myeloablative conditioning in cord blood transplantation for hematological malignancies: A retrospective (development) and a prospective (validation) study. Sun Zimin,Liu Huilan,Luo Chenhui,Geng Liangquan,Zheng Changcheng,Tang Baolin,Zhu Xiaoyu,Tong Juan,Wang Xingbing,Ding Kaiyang,Wan Xiang,Zhang Lei,Yao Wen,Song Kaiding,Zhang Xuhan,Wu Yue,Yang Huizhi,Han Yongsheng,Liu Xin,Zhu Weibo,Wu Jingsheng,Wang Zuyi International journal of cancer Cord blood transplantation (CBT) is an effective option for treating hematological malignancies, but graft failure (GF) remains the primary cause of therapy failure. Thus, based on myeloablative conditioning (MAC) of busulfan with cyclophosphamide (Bu/Cy) or total body irradiation with Cy (TBI/Cy), fludarabine (Flu) was added to Bu/Cy and cytarabine (CA) to TBI/Cy for a modified myeloablative conditioning (MMAC). To compare the prognosis of MMAC with MAC, we conducted a retrospective study including 58 patients who underwent CBT with MAC or MMAC from 2000 to 2011. Neutrophil and platelet engraftment rate, overall survival (OS) and disease free survival (DFS) were significantly higher in the MMAC group (adjusted hazard ratio [HR], 2.58, 2.43, 0.36 and 0.37; p < 0.01, p = 0.01, p = 0.02 and p = 0.02, separately). Nonrelapse mortality (NRM) was comparable (p = 0.183). To validate the outcomes noted in the MMAC group, we conducted a prospective single-arm clinical trial including 188 patients who underwent CBT with MMAC from 2011 to 2015. Engraftment rate, survival and NRM of the MMAC group in the prospective trail (MMAC-P) were similar to the MMAC group in the retrospective study (MMAC-R). This study is the first to demonstrate the superiority of MMAC to MAC in CBT for hematological malignancies. 10.1002/ijc.31339
High expression of ESRP1 regulated by circ-0005585 promotes cell colonization in ovarian cancer. Cancer cell international BACKGROUND:Ovarian cancer is the third most common gynecological cancer in the world but the leading cause of death among gynecological malignancies. Epithelial splicing regulatory protein-1 (ESRP1), a key negative splicing regulator in epithelial-mesenchymal transition (EMT), has been proven to be overexpressed and may plays a role in epithelial ovarian cancer (EOC) progression. However, the functional roles of ESRP1 and the underlying mechanisms in this process still remain unclear. METHODS:Tumor invasion, migration, colony formation and animal experiments were used to study the malignant biological behavior of ESRP1. A vector-based system expressing circ-0005585 was established to investigate circRNA as a microRNAs sponge. RNA-Seq and cytoskeleton staining explored underlying mechanisms of ESRP1. RESULTS:Our results demonstrated that circ-0005585 regulates ESRP1 overexpression via sponging miR-23a/b and miR-15a/15b/16. Overexpression of ESRP1 suppresses EOC cell migration, but promotes colonization and drives a switch from mesenchymal to epithelial phenotype (MET) in association with actin cytoskeleton reorganization, mainly by alternative splicing EPB41L5 and RAC1. Furthermore, we have shown that high ESRP1 expression may be associated with immune-suppression in tumor immune microenvironment in vivo. CONCLUSIONS:ESRP1 overexpression promotes MET status and correlates with actin cytoskeleton reorganization in EOC. ESRP1 plays an important role in EOC colonization. In addition, a miRs panel from two miR families can inhibit ESRP1, may provide an innovative approach for cancer theranostics. 10.1186/s12935-020-01254-3
