Epigenetic status of argininosuccinate synthetase and argininosuccinate lyase modulates autophagy and cell death in glioblastoma. [PDF]

, 2012
Arginine deprivation, either by nutritional starvation or exposure to ADI-PEG20, induces adaptive transcriptional upregulation of ASS1 and ASL in glioblastoma multiforme ex vivo cultures and cell lines.

In vitromethylation of CpG-rich islands

Nucleic Acids Research, 1989
CpG islands are distinguishable from the bulk of vertebrate DNA for being unmethylated and CpG-rich. Since CpG doublets are the specific target of eukaryotic DNA methyltransferases, CpG-rich sequences might be expected to be good methyl-accepting substrates in vitro, despite their unmethylated in vivo condition.

CpGIF: an algorithm for the identification of CpG islands [PDF]

Bioinformation, 2008
CpG islands (CGIs) play a fundamental role in genome analysis and annotation, and contribute to improving the accuracy of promoter prediction. Besides, CGIs in promoter regions are abnormally methylated in cancer cells and thus can be used as tumor markers. However, current methods for identifying CGIs suffer from various drawbacks.

Mitigating Cell Cycle Effects in Multi‐Omics Data: Solutions and Analytical Frameworks

Advanced Science, EarlyView.
The study highlights the cell‐cycle effects on multi‐omics analysis attributed to varying cell cycle compositions across cell types. To minimize the influence, we propose RTD correction in CNV calling with a high S‐phase ratio, and phase comparison in chromatin accessibility, DNA methylation, and transcriptomics.

Alzheimer's Association clinical practice guideline for the Diagnostic Evaluation, Testing, Counseling, and Disclosure of Suspected Alzheimer's Disease and Related Disorders (DETeCD‐ADRD): Executive summary of recommendations for primary care

Alzheimer's &Dementia, EarlyView.
Abstract US clinical practice guidelines for the diagnostic evaluation of cognitive impairment due to Alzheimer's disease (AD) or AD and related dementias (ADRD) are decades old and aimed at specialists. This evidence‐based guideline was developed to empower all—including primary care—clinicians to implement a structured approach for evaluating a ...

Epigenome-wide association study reveals decreased average methylation levels years before breast cancer diagnosis [PDF]

, 2015
Interest in the potential of DNA methylation in peripheral blood as a biomarker of cancer risk is increasing. We aimed to assess whether epigenome-wide DNA methylation measured in peripheral blood samples obtained before onset of the disease is ...

Distribution of DNA methylation, CpGs, and CpG islands in human isochores

Genomics, 2010
DNA methylation is a major epigenetic modification of the genome that affects basic biological functions, such as gene expression and cell development. We used the human genome sequences and the DNA methylation data that are available in order to establish a map of the levels of GC and methylation in isochores.

Mining and Predicting CpG islands [PDF]

2007 IEEE International Fuzzy Systems Conference, 2007
A DNA sequence can be described as a string composed of four symbols: A, T, C and G. Each symbol represents a chemically distinct nucleotide molecule. Combinations of two nucleotides are called dinucleotides and CpG islands represent regions of a DNA sequence, certain substrings, which are enriched in CpG dinucleotides (C followed by G).

Approaches to repurposing reverse transcriptase antivirals in cancer

British Journal of Clinical Pharmacology, EarlyView.
This review highlights the role of reverse transcriptase (RT) inhibition in cellular regulation associated with non‐terminal repeat retrotransposons and endogenous retroviruses. Based on their pleiotropic characteristics, RT inhibitors (RTIs) are discussed as potential anticancer agents.
