Evaluation of 3′-phosphate as a transient protecting group for controlled enzymatic synthesis of DNA and XNA oligonucleotides

open access: yesCommunications Chemistry, 2022
Controlled enzymatic DNA synthesis represents an alternative synthetic methodology that circumvents the limitations of traditional soild-phase synthesis. Here, the authors explore the use of 3’-phosphate as a transient protecting group for the controlled

Obesity alters the fitness of peritumoral adipose tissue, exacerbating tumor invasiveness in renal cancer through the induction of ADAM12 and CYP1B1

open access: yesMolecular Oncology, EarlyView.
Tumor microenvironment drives cancer formation and progression. We analyzed the role of human cancer‐associated adipocytes from patients with renal cell carcinoma (RCC) stratified as lean, overweight, or obese. RNA‐seq demonstrated that, among the most altered genes involved in the tumor–stroma crosstalk, are ADAM12 and CYP1B1, which were proven to be ...

Cap-proximal nucleotides via differential eIF4E binding and alternative promoter usage mediate translational response to energy stress

open access: yeseLife, 2017
Transcription start-site (TSS) selection and alternative promoter (AP) usage contribute to gene expression complexity but little is known about their impact on translation.

Enzymatic Synthesis of Vancomycin-Modified DNA

open access: yesMolecules, 2022
Many potent antibiotics fail to treat bacterial infections due to emergence of drug-resistant strains. This surge of antimicrobial resistance (AMR) calls in for the development of alternative strategies and methods for the development of drugs with ...

Detection rate for ESR1 mutations is higher in circulating‐tumor‐cell‐derived genomic DNA than in paired plasma cell‐free DNA samples as revealed by ddPCR

open access: yesMolecular Oncology, EarlyView.
Analysis of ESR1 mutations in plasma cell‐free DNA (cfDNA) is highly important for the selection of treatment in patients with breast cancer. Using multiplex‐ddPCR and identical blood draws, we investigated whether circulating tumor cells (CTCs) and cfDNA provide similar or complementary information for ESR1 mutations.

Exploring potential of i-motif DNA formed in the promoter region of GRIN1 gene for nanotechnological applications

open access: yesResults in Chemistry, 2020
The tandem repeat stretches of cytosine residues fold to construct intercalated motif (i-motif) structures over an acidic pH range. Several advancements have been made to understand the biological role of i-motif DNA.

Molecular structure and interactions of nucleic acid components in nanopaticles: ab initio calculations [PDF]

open access: yesUkrainian Journal of Physics, 2012, Vol. 57, no. 7, pp. 723-731, 2012
Self-associates of nucleic acid components (stacking trimers and tetramers of the base pairs of nucleic acids) and short fragments of nucleic acids are nanoparticles (linear sizes of these particles are more than 10 A. Modern quantum-mechanical methods and softwares allow one to perform ab initio calculations of the systems consisting of 150-200 atoms ...

Targeted metabolomics reveals novel diagnostic biomarkers for colorectal cancer

open access: yesMolecular Oncology, EarlyView.
This study employed targeted metabolomic profiling to identify 302 distinct metabolites present in platelet‐rich plasma (PRP), revealing aberrant metabolic profiles amongst individuals diagnosed with colorectal cancer (CRC). Compared to carcinoembryonic antigen (CEA) and cancer antigen 19‐9 (CA199), our metabolite panel showed improved sensitivity ...

Oxidative Stress: A Key Modulator in Neurodegenerative Diseases

open access: yesMolecules, 2019
Oxidative stress is proposed as a regulatory element in ageing and various neurological disorders. The excess of oxidants causes a reduction of antioxidants, which in turn produce an oxidation–reduction imbalance in organisms.

Clinical significance of stratifying prostate cancer patients through specific circulating genes

open access: yesMolecular Oncology, EarlyView.
We tested a specific panel of genes representative of luminal, neuroendocrine and stem‐like cells in the blood of prostate cancer patients, showing predictive value from diagnosis to late stages of disease. This approach allows monitoring of treatment responses and outcomes at specific time points in trajectories.
