UNLABELLED Screening of biomarker expression levels in tumor biopsy samples not only provides an assessment of prognostic and predictive factors, but may also be used for selection of biomarker-specific imaging strategies. To assess the feasibility of using a biopsy specimen for a personalized selection of an imaging agent, the chemokine receptor 4 (CXCR4) was used as a reference biomarker. M...

Different neurodegenerative disorders, such as Alzheimer's disease (AD) and frontotemporal dementia (FTD), lead to dementia syndromes. Dementia will pose a huge impact on society and thus it is essential to develop novel tools that are able to detect the earliest, most sensitive, discriminative, and dynamic biomarkers for each of the disorders. To date, the most common assays used in large-scal...

The history of biomarkers and ultrasonography dates back over more than 50 years. The present status of biomarkers used in the context of ovarian cancer is addressed. Attention is given to new interpretations of the etiology of ovarian cancer. Cancer antigen 125 (CA125) and multivariate index assays (Ova1, Risk of Ovarian Malignancy Algorithm, Overa) are biomarker-driven considerations that are...

Chromosome engineering is a useful strategy for transfer of alien genes from wild relatives into modern crops. However, this strategy has not been extensively used for alien gene introgression in most crops due to low efficiency of conventional cytogenetic techniques. Here, we report an improved scheme of chromosome engineering for efficient elimination of a large amount of goatgrass (Aegilops ...

PURPOSE OF REVIEW Given the poor prognosis associated with lung cancer, the ability to diagnose lung cancer in its early stages is considered crucial to achieving decreased lung cancer mortality. Herein, we discuss recent advances in biomarker discovery and evaluation of their potential application in the clinical setting. RECENT FINDINGS Novel potential biomarkers have been identified via ne...

Molecular profiling of liquid biopsies is now emerging as pivotal for cancer biomarker discovery. The low-invasive nature of the approach used for collecting biospecimens (i.e. blood, urine, saliva, etc.) may allow a widespread application of novel molecular diagnostics based on liquid biopsies. This is relevant, for example, in cancer screening programmes where it is essential to reduce costs ...

BACKGROUND Modern genomic and proteomic studies reveal that many diseases are heterogeneous, comprising multiple different subtypes. The common notion that one biomarker can be predictive for all patients may need to be replaced by an understanding that each subtype has its own set of unique biomarkers, affecting how discovery studies are designed and analyzed. METHODS We used Monte Carlo sim...

An accurate biomarker for the follow-up of women positive for human papillomavirus type 16 (HPV16) DNAmay improve the efficiency of cervical cancer prevention. Previously, we analyzed all 113HPV16CpGs in cervical cytology samples and discovered differential methylation at different stages of premalignancy. In the current study, we identified amethylation biomarker consisting of a panel of 12HPV...

Abstract Cancer ranks as a leading cause of death and huge obstacle to rising life expectancy. If cancers are spotted early there's high chance survival. The conventional methods relying on the phenotypic features tumor not powerful screening cancer. biomarkers capable indicating specific cancer states. Current biochemical assay suffers from time reagents consuming discontinuous monitoring. Sur...
