miR-34a and miR-29b as indicators for prognosis of treatment-free survival of chronic lymphocytic leukemia patients in Chinese Uygur and Han populations

Publication date: Available online 16 August 2019Source: Molecular and Cellular ProbesAuthor(s): Yan Li, Min Mao, Hong Liu, Xiaomin Wang, Zhen Kou, Yuling Nie, Yichun Wang, Zengsheng Wang, Qin Huang, Tao Lang, Zailinuer Gu, Li An, Xiaoyan Zhang, Lin FuAbstractThe abnormal expression of miRNAs may play critical roles in the occurrence, development and prognosis of chronic lymphocytic leukemia (CLL), with potential ethnic differences being involved. p53 and immunoglobulin heavy chain variable region gene (IGVH) mutations were monitored and miRNA profile screening of CD19 + cells from Uygur CLL patients was performed, analyzed by miRNA arrays and verified using real-time PCR. There were 68 differentially expressed miRNAs in CD19 + B lymphocytes obtained from 6 Uygur CLL patients, of which miR-1295, miR-29b, miR-34a, miR-21 and miR-29c were the 5 most upregulated, and miR-181a, miR-126, miR-181b, miR-125a-5p and miR199b the 5 most downregulated miRNAs. miR-15a/miR-16-1 which might be important drivers of the disease, were not eliminated by profile screening. From the 68 differentially expressed miRNAs, 5 previously-reported CLL-related miRNAs were selected for further confirmation analyses, from which expression levels of miR-29b, miR-34a and miR-155 were found to be increased while miR-181a and miR-181b decreased. However, there were no differences in the expression levels of miR-15a/miR-16-1 between CLL patients and healthy donors, but the expression levels of miR-15a/m...

Objective: The Patient-Reported Outcomes Measurement Information System Cognitive Function-Concerns® (PROMIS®-CF-Concerns) assesses self-reported cognitive complaints. Construct validity data for the CF-Concerns are few. To add to the literature, an analysis of criterion validity for cognitive complaints (European Organisation for Research and Treatment of Cancer—Cognitive Functioning subscale [EORTC-CF]) and cognitive performance (neuropsychological tests of memory [NIH Toolbox Auditory Verbal Learning Test] and verbal fluency [Controlled Oral Word Association Test]) and discriminant validity (self-reports o...

In conclusion, we identified a novel Bcl-2 inhibitor by QSAR screening, which exerted significant cytotoxic activity in breast cancer cells through inducing mitochondria-mediated apoptosis. Introduction Apoptosis is a process of cellular suicide through which unwanted or unhealthy cells are eliminated during organism development or cellular stress (Reed, 2002; Fernald and Kurokawa, 2013). Deregulated apoptosis is a characteristic of cancers (Doi et al., 2012; Roizen, 2012). The B-cell lymphoma-2 (Bcl-2) family is composed of pro- and anti-apoptotic proteins, plays pivotal role in the mitochondrial pathway of apoptosi...

In conclusion, osmotic burst of inflated complement-damaged cells may occur, but these bursts are most likely a consequence of metabolic collapse of the cell rather than the cause of cell death. The Complement Cell Death Mediator: A Concerted Action of Toxic Moieties Membrane pores caused by complement were first visualized by electron microscopy on red blood cell membranes as large ring structures (22). Similar lesions were viewed on E. coli cell walls (23). Over the years, ample information on the fine ultrastructure of the MAC that can activate cell death has been gathered (24) and has been recently further examined (...

Conclusions: CAR T cell therapies have demonstrated the clinical benefits of harnessing our body's own defenses to combat tumor cells. Similar research is being conducted on lesser known modifications and gene-modified immune cells, which we highlight in this review. Introduction Chimeric antigen receptors and engineered T cell receptors (based on previously identified high affinity T cell receptors) function by redirecting T cells to a predefined tumor-specific (or tumor-associated) target. Most of these modifications use retroviral or lentiviral vectors to integrate the construct, and most of the receptors ...

Authors: Ayubcha C, Hosoya H, Seraj SM, Zadeh MZ, Werner T, Alavi A Abstract Fluorine-18 fluorodeoxyglucose positron emission tomography (18F-FDG PET) imaging was conceived in the early 1970 by investigators at the University of Pennsylvania as a research technique to measure brain metabolism and function by employing a non-invasive imaging approach. Soon after the introduction of whole-body PET instruments, 18F-FDG was utilized in the assessment of a variety of solid tumors and certain hematological malignancies. Yet, the role of 18F-FDG in assessing benign and uncommon malignant disorders of the bone marrow has n...

We report adverse events that occurred or persisted beyond 90 days after the last CAR-T cell infusion, excluding events related to disease progression.Median age at CAR-T cell infusion was 60 years (range, 34-73). There were 42 (71%) pts with NHL and 17 (29%) with CLL. The median number of prior lines of treatment was 4 (range, 1-8). 23 (39%) pts had received prior autologous (auto) hematopoietic cell transplantation (HCT), and 9 (15%) pts had received prior allogeneic (allo) HCT. 35 (59%) pts received one CAR-T cell infusion, 22 (37%) pts received 2 infusions, and 2 (3%) pts received 3 infusions. 3 (5%) pts received a max...

CONCLUSION Cognitive impairment can affect daily functioning, quality of life, and capacity to work in patients with cancer and those in remission. Consequently, cognitive assessment is now an important and necessary part of a comprehensive oncological care plan. Cancer-related cognitive impairment might be due to the direct effects of the cancer itself, nonspecific factors, or comorbid conditions that are independent of the disease and/or due to the adverse effects of the treatment or combination of treatments given for the disease. The prevalence and extent of cognitive impairment associated with cancer is recognized but...

Conclusion Our results suggest that intraperitoneal injection of TMX may ameliorate TBI-induced depression-like behavior in rats by increasing neuronal p-ERK1/2 expression, which may be associated with neuronal Bcl2 and BDNF expression and decreased neuronal apoptosis. This effect might represent a mechanism underlying the recovery from depression-like behavior.
