Role Of TP53 mutations in predicting the clinical efficacy of hypomethylating therapy in patients with myelodysplastic syndrome and related neoplasms: a systematic review and meta-analysis
Abstract Hypomethylating agents (HMAs) are now a major treatment option for myelodysplastic syndrome (MDS) and related neoplasms, but 50% of patients still do not respond and realize poor outcomes. Mutational predictors of treatment efficacy attract continuous attention. Whether TP53 mutations can be used as predictors of HMA effectiveness has caused heated debate. Therefore, we performed a meta-analysis to investigate the predictive value of TP53 mutations to outcomes of HMA therapy in patients with MDS and related neoplasms. We systematically searched PubMed, Embase, the Cochrane Library, and the WanFang databases (publi...

Six long noncoding RNAs as potentially biomarkers involved in competitive endogenous RNA of hepatocellular carcinoma
AbstractTo investigate lncRNAs acting as competing endogenous RNAs (ceRNAs) involved in oncogenesis and progression of HCC. Different expressed lncRNAs, microRNAs, and mRNAs (DElncRNAs, DEmiRNAs, DEmRNAs), downloaded from The Cancer Genome Atlas (TCGA) database, were identified by edgeR package. CeRNA network was constructed based on miRcode, TargetScan, and miRTarBase. Target DEmRNAs were annotated by KEGG pathway and GO analysis. Negatively correlated lncRNA-miRNA pairs were analyzed by Pearson correlation coefficient, simultaneously, overall survival (OS) were evaluated. The expression of these lncRNAs were examined in ...

Expression of BAFF and BAFF receptors in primary Sj ögren’s syndrome patients with ectopic germinal center-like structures
AbstractB cell-activating factor (BAFF) is an essential cytokine in primary Sj ögren’s syndrome (pSS) physiopathology. It has been reported that pSS patients develop germinal center-like (GC-like) structures in their minor salivary glands (MSGs). BAFF, BAFF-R, TACI, and BCMA expression was analyzed in MSGs from 29 subjects (nonspecific chronic sialadenitis and focal lymphoc ytic sialadenitis with the presence [pSS-GC(+)] or absence [pSS-GC(−)] of GC-like structures).

The current state of MiRNAs as biomarkers and therapeutic tools
AbstractMicroRNAs (miRNAs) are non-coding RNAs with a length of 18 –22 nucleotides that regulate about a third of the human genome at the post-transcriptional level. MiRNAs are involved in almost all biological processes, including cell proliferation, apoptosis, and cell differentiation, but also play a key role in the pathogenesis of many diseases. Most miRNAs a re expressed within the cells themselves. Due to various forms of transport from cells like exosomes, circulating miRNAs are stable and can be found in human body fluids, such as blood, saliva, cerebrospinal fluid, and urine. Circulating miRNAs are of great ...

IL-10 suppresses IFN- γ-mediated signaling in lung adenocarcinoma
In this study, we examined the expression of IL-10 and IL-10 receptor 1 (IL-10R1) in resected locally advanced lung adenocarcinoma by immunohistochemistry. IL-10 immunoreactivity was stronger in intraepithelial regions than in stroma. The amount of IL-10 found either in intraepithelial or in stromal regions had no prognostic value, but the relative distribution of IL-10 in these two locations was related to cancer-immune phenotypes. High expression of IL-10R1 by tumor cells was significantly correlated with poor prognosis, suggesting that IL-10-mediated signaling may induce cancer cell intrinsic effects that promote cancer...

AbstractChronic hepatitis C (CHC) infection is associated with increased TIM-3, PD-1 immune checkpoint receptors expression that inhibits adaptive T cells and increases NK cell cytotoxicity against T helper cells, both resulting T cell exhaustion. Elimination of the virus with direct-acting antivirals (DAAs) may modify host immune response via altering these immune checkpoint receptors ’ expression.

Patient-derived xenograft models for personalized medicine in colorectal cancer
AbstractEstablishing superior preclinical models is critical for translational cancer research owing to the high failure rates of novel therapeutics in clinical studies. Even though cell line-derived xenograft models are easy to create, they have numerous limitations since these models do not represent the distinctive features of each cancer patient adequately. To circumvent the discrepancies between xenograft models and tumors, patient-derived xenograft (PDX) models have been developed. These models are established through the engraftment of tissue from a patient ’s tumor into an immune-deficient mouse, which preser...

Extramedullary blastic transformation of primary myelofibrosis in the form of disseminated myeloid sarcoma: a case report and review of the literature

The role of fibroblast activation protein in progression and development of osteosarcoma cells
AbstractTo investigate the expression levels of fibroblast activation protein (FAP) in human osteosarcoma tissues and its possible correlations with clinical pathological characteristics of patients with osteosarcoma, and to explore the potential effects of FAP on progression and development of osteosarcoma. Immunohistochemistry (IHC) assay was initially performed to detect the expression levels of FAP in 66 tumor tissues and adjacent non-tumor tissues. Patients were sequentially divided into two groups based on diffe rent expression levels of FAP. The correlations between the expression levels of FAP and the clinica...

Hepatic dysfunction secondary to Kawasaki disease: characteristics, etiology and predictive role in coronary artery abnormalities
AbstractCoronary artery abnormalities (CAAs) are prominent during the acute Kawasaki disease (KD) episode and represent the major contributors to the long-term prognosis. Several meta-analysis and published scoring systems have identified hepatic dysfunction as an independent predictor of CAA risks. The medical records of 210 KD children were reviewed. Blood samples were collected from all subjects at 24 h pre-therapy and 48 h post-therapy, respectively. Liver function test (LFT) and inflammatory mediators were detected. Multivariate logistic regression analysis was conducted to identify the reliable biomarkers ...

Senescence-associated miR-34a and miR-126 in middle-aged Indians with type 2 diabetes
AbstractRapid urbanization and unhealthy dietary patterns critically increase the risk of type 2 diabetes (T2D) in middle-aged Indians. However, despite recent evidence of senescence-associated microRNAs (SA-miRNAs) in regulating complex pathways of ageing, their expressions in middle-aged Indians with T2D remain unexplored. Hence we aimed to investigate the changes in expressions of SA-miRNAs miR-34a and miR-126 in middle-aged T2D patients. A total of 30 T2D patients and 30 controls were recruited of age 31–50 years. The expressions of plasma miR-34a and miR-126 were determined by quantitative PCR. Oxidiz...
