On the electronic structure of methyl butyrate and methyl valerate [PDF]
The European Physical Journal D, 2020 AbstractWe present novel results of the analysis of the electronic structure of two aliphatic esters: methyl butyrate and methyl valerate. High-resolution photoabsorption spectra were collected and analyzed over the energy range 4.0–10.8 eV and showed for both the molecules not only a clear band of the HOMO to LUMO transition, but also vibronic ...

lncRNA Mirt2 upregulates miR‐1246 through methylation to suppress LPS‐induced lung cell apoptosis
Immunity, Inflammation and Disease, 2021 Introduction Long noncoding RNA Mirt2 has been proven to be a suppressor of lipopolysaccharide (LPS) (a key player in sepsis)‐induced inflammation responses. Therefore, Mirt2 may also participate in sepsis.

Interstellar Isomers: The Importance of Bonding Energy Differences [PDF]
Astrophys.J.632:333-339,2005, 2005 We present strong detections of methyl cyanide, vinyl cyanide, ethyl cyanide and cyanodiacetylene molecules with the Green Bank Telescope (GBT) toward the Sgr B2(N) molecular cloud. Attempts to detect the corresponding isocyanide isomers were only successful in the case of methyl isocyanide for its J(K)=1(0)-0(0) transition, which is the first ...

Methylation of demethylavermectins [PDF]
Antimicrobial Agents and Chemotherapy, 1987 Demethylavermectins, which lack methyl groups on the oleandrose moiety, were fed to wild-type "Streptomyces avermitilis," which produces the normal avermectin components, and the bioconversion products were identified. The oleandrose units of the demethylavermectins were not methylated by the wild-type strain, but the C-5 of the macrolide ring was ...

Frontiers in Genetics, 2020 There are associations between DNA methylation and the expression of long non-coding RNA (lncRNA), also known as lncRNA expression quantitative trait methylations (lnc-eQTMs). Lnc-eQTMs may induce a wide range of carcinogenesis pathways.

DNA methylation arrays as surrogate measures of cell mixture distribution
BMC Bioinformatics, 2012 There has been a long-standing need in biomedical research for a method that quantifies the normally mixed composition of leukocytes beyond what is possible by simple histological or flow cytometric assessments.

Classification of large DNA methylation datasets for identifying cancer drivers [PDF]
F. Celli, F. Cumbo, E. Weitschek: Classification of Large DNA
Methylation Datasets for Identifying Cancer Drivers. Big Data Research,
10.1016/j.bdr.2018.02.005, 2018, 2018 DNA methylation is a well-studied genetic modification crucial to regulate the functioning of the genome. Its alterations play an important role in tumorigenesis and tumor-suppression. Thus, studying DNA methylation data may help biomarker discovery in cancer.
