Abstract
Fat mass and obesity-associated protein (FTO) is the first reported N6-methyladenosine (m6A) RNA demethylase. The dysregulation of FTO demethylation is strongly associated with various human cancers in a m6A-dependent manner. Herein, a homogeneous electrochemiluminescence (ECL) method for the determination of FTO was proposed based on the target-regulated DNAzyme cleavage. Moreover, the ECL signal was highly enhanced by host-guest interaction between β-cyclodextrin (β-CD) and tri-n-propylamine (TPrA). The m6A caged DNAzyme 17E-Me acted as a padlock, while the FTO served as the corresponding key. As the key, FTO could specifically remove m6A modification, restoring the cleavage activity of DNAzyme 17E. With the assistance of the Zn2+ cofactor, the substrate strand was cleaved at a specific site, and the ECL indicator of Ru(phen)32+ was discharged to produce an ECL signal. On the contrary, 17E-Me was blocked and no cleavage reaction occurred without the key. For the ECL detection, the electrode modification of β-CD@AuNPs concentrated Ru(phen)32+ species through electrostatic adsorption and gathered TPrA molecules through host-guest interaction with β-CD, which resulted in an intense ECL response. The results demonstrated the ECL intensity linearly correlated with the logarithm of the FTO concentration (from 0.0001 to 100 nM) with a low detection limit (30 fM). The IC50 value for FTO inhibitors rhein and meclofenamic acid were 35.6 μM and 20.3 μM, respectively. The strategy was further validated for FTO detection in MCF-7 cell lysates and Hela cell lysates. This work reveals that this strategy is promising for developing homogeneous ECL method for detection of FTO and screening of the demethylase inhibitors.

Abstract
The relationship between endocrine system disorders and health risks due to chemical environmental compounds has become a growing concern in recent years. Involuntary exposure to endocrine disruptors (EDCs) is associated with the worldwide increase of diseases such as cancer, obesity, diabetes, and neurocortical disorders. EDCs are compounds that target the nuclear hormonereceptors (NHR) leading to epigenetic changes. Consequently, the use of biosensing strategies based on epigenetic events have a great potential to provide outstanding information about the exposition of EDCs and their evaluation in human health. This review addresses the novel trends in biosensing EDCs evaluation based on DNA methylation assays associated with different human diseases.

Abstract
DNA methylation is one of the significant epigenetic modifications involved in mammalian development as well as in the initiation and progression of various diseases like cancer. Over the past few decades, an enormous amount of research has been carried out for the quantification of DNA methylation in the mammalian genome. Earlier, most of these methodologies used bisulfite treatment. However, the low conversion, false reading, longer assay time and complex chemical reaction are the common limitations of this method that hinder their application in routine clinical screening. Thus, as an alternative to bisulfite conversion-based DNA methylation detection, numerous bisulfite-free methods have been proposed. In this regard, electrochemical biosensors have gained much attention in recent years for being highly sensitive yet cost-effective, portable, and simple to operate. On the other hand, biosensors with optical readouts enable direct real time detection of biological molecules and are easily adaptable to multiplexing. Incorporation of electrochemical and optical readouts into bisulfite free DNA methylation analysis is paving the way for the translation of this important biomarker into standard patient care. In this review, we provide a critical overview of recent advances in the development of electrochemical and optical readout based bisulfite free DNA methylation assays.
