BACKGROUND: Circular RNAs (circRNAs) are a class of non-coding RNAs (ncRNAs) and characterized by covalently closed loop without 5' and 3' end. Recently, the diagnostic value of circRNAs has received more and more attention. However, the in-depth study about circRNAs diagnosis in breast cancer is still rarely reported. In present study, we try to investigate the circRNAs expression profiles in breast cancer peripheral blood and discover valuable diagnostic biomarkers. METHODS: The expression profiles of circRNAs in plasma specimens were screened from five breast cancer and paired healthy volunteer s...

Background: Detection of circulating tumor DNA (ctDNA) can be limited due to their relative scarcity in circulation, particularly while patients are actively undergoing therapy. Exosomes provide a vehicle through which cancer-specific material can be enriched from the compendium of circulating non-neoplastic tissue-derived nucleic acids. We performed a comprehensive profiling of the pancreatic ductal adenocarcinoma (PDAC) exosomal "surfaceome" in order to identify surface proteins that will render liquid biopsies amenable to cancer-derived exosome enrichment for downstream molecular profiling...

Chromosomal aberrations (CAs) in blood lymphocytes have been shown to be associated with overall cancer risk and aging. However, their relationship to bladder cancer risk remains to be elucidated. In a case-control study of bladder cancer in Egypt, we examined the relationship between the increased frequency of CAs in blood lymphocytes and bladder cancer risk. High frequency of CAs was significantly associated with an increased risk of bladder cancer [adjusted odds ratios (OR) = 3.90, 95% confidence interval (CI) = 2...

Galectins are moving closer to center stage in detecting glycosylation aberration in cancer cells. Here, we have investigated the expression of galectins in ovarian cancer (OC) and examined their potential as biomarkers in tissues and blood plasma samples of high grade serous ovarian carcinoma (HGSC) patients. In tissues, we found that increased protein expression of stromal gal-1 and epithelial gal-8/9 was associated with a poor response to treatment of HGSC patients. Gal-8/9 were both independent predictors of chemoresistance and overall survival (OS), respectively...

BACKGROUND: Endometrial cancer (EC) is currently considered the fourth most frequent female cancer in Europe. In an attempt to achieve an early diagnosis, many studies have identified some putative biomarkers for gynecologic cancers, including circulating microRNAs (miRs) and aberrant promoter methylation status. Previous studies which have investigated miR-203 expression profiles in EC tissues and normal endometrial tissues concluded that miR-203 is regulated by methylation promoter...

BACKGROUND: MicroRNAs (miRNAs) are small non-coding RNAs able to regulate gene expression at multiple levels. They are detected in tissues, blood, and other body fluids with high stability and have a recognized role in the maintaining of tissue homeostasis. Aberrant expression profile of miRNAs has been observed in several diseases, primarily cancer. As a consequence, the analysis of miRNA signature has recognized diagnostic and prognostic role in human diseases, and the development of miRNA-based therapies is currently under investigation...

REVIEW
K Date, C Ettelaie, A Maraveyas
Cancer is associated with an increased risk of venous thromboembolism (VTE); the exact mechanisms for the induction of VTE remain to be fully elucidated, yet it is widely acknowledged that tissue factor-positive microparticles (TF-MPs) may play a significant role. However, TF-MPs have yet to be accepted as a bona fide biomarker for cancer-associated VTE, as the presence of elevated TF-MPs levels is not always accompanied by thrombosis; interestingly in certain cases, particularly in pancreatic cancer, VTE seems to be more likely in the context of acute inflammation...

Lymphodepletion chemotherapy followed by infusion of CD19-targeted chimeric antigen receptor-modified T (CAR-T) cells can be complicated by neurologic adverse events (AE) in patients with refractory B-cell malignancies. In 133 adults treated with CD19 CAR-T cells, we found that acute lymphoblastic leukemia, high CD19(+) cells in bone marrow, high CAR-T cell dose, cytokine release syndrome, and preexisting neurologic comorbidities were associated with increased risk of neurologic AEs. Patients with severe neurotoxicity demonstrated evidence of endothelial activation, including disseminated intravascular coagulation, capillary leak, and increased blood-brain barrier (BBB) permeability...

Background: There is convincing evidence that high physical activity lowers the risk of colon cancer; however, the underlying biological mechanisms remain largely unknown. We aimed to determine the extent to which body fatness and biomarkers of various biologically plausible pathways account for the association between physical activity and colon cancer. Methods: We conducted a nested case-control study in a cohort of 519 978 men and women aged 25 to 70 years followed from 1992 to 2003...

Triple negative breast cancer (TNBC) is highly aggressive and has a few therapeutic treatments, so new targeted therapy and biomarkers are required to provide alternative choices for treating TNBC patients. Recent studies showed that vasculogenic mimicry (VM), the formation of blood channels by aggressive cancer cells that mimic endothelial cells, is a factor contributing to poor prognosis in TNBC. Wilms' tumor 1 (WT1) gene has been found to be highly expressed in TNBC, and has 4 major distinct isoforms; isoform A (-17AA/-KTS; -/-), isoform B (+17AA/-KTS; +/-), isoform C (-17AA/+KTS; -/+) and isoform D (+17AA/+KTS; +/+)...

The International Agency for Research on Cancer has classified diesel engine exhaust (DEE) as a human lung carcinogen. Given that inflammation is suspected to be an important underlying mechanism of lung carcinogenesis, we evaluated the relationship between DEE exposure and the inflammatory response using data from a cross-sectional molecular epidemiology study of 41 diesel engine testing workers and 46 unexposed controls. Repeated personal exposure measurements of PM2.5 and other DEE constituents were taken for the diesel engine testing workers before blood collection...

Cervical cancer is one of the most common cancers among women worldwide. It is highly lethal yet can be treated when found in early stage. Thus, early detection is of significant important for early diagnosis of cervical cancer. Exosomes have been used as biomarkers in clinical diagnosis. It is unknown that whether blood exosomes associated with cervical cancer can be detected and if these exosomes can accurately represent the developmental stage of cervical cancer. Mouse models were made out of a relapsed cervical cancer patient's tumour sample for original and recurrent cervical cancer, and gene analysis in both tumours and exosomes in these mouse models were performed...

Circulating endothelial cells (CECs), originated form endothelial progenitors (EPCs) are mature cells which are not associated with vessel walls, and that are detached from the endothelium. Normally, they are present in insignificant amounts in the peripheral blood of healthy individuals. On the other hand, elevated CECs and EPCs levels have been reported in the peripheral blood of patients with different types of cancers and some other diseases. Consequently, CECs and EPCs represent a potential biomarker in several clinical conditions involving endothelial turnover and remodeling, such as hematological diseases...

Changes in mitochondrial DNA (mtDNA) content is a useful clinical biomarker for various diseases, however results are controversial as several analytical factors can affect measurement of mtDNA. MtDNA is often quantified by taking ratio between a target mitochondrial gene and a reference nuclear gene (mtDNA/nDNA) using quantitative real time PCR often on two separate experiments. It measures relative levels by using external calibrator which may not be comparable across laboratories. We have developed and optimized a droplet digital PCR (ddPCR) based method for quantification of absolute copy number of both mtDNA and nDNA gene in whole blood...

BACKGROUND: Fibroblast growth factor 21 (FGF-21) is mainly secreted by liver and has been reported to be involved in the pathogenesis of type 2 diabetes. Some prospective studies have shown a positive association between FGF-21 and diabetes risk. However, no study has examined whether the association differed by sex, which has been reported between FGF-21 and atherosclerosis. Therefore, we prospectively evaluated the sex-specific association between FGF-21 and diabetes in a Chinese population...
