Study of the multiple incorporation of modified nucleotides into the growing DNA strand

open access: yesТонкие химические технологии, 2021
Objectives. This study investigated the substrate properties of the modified derivatives of triphosphates of purine and pyrimidine deoxynucleosides (5-propynyl-2’-deoxyuridine-5’-triphosphate, 5-propynyl2’-deoxycytidine-5’-triphosphate, 5-methyl-2 ...

Purine nucleoside phosphorylase enables dual metabolic checkpoints that prevent T cell immunodeficiency and TLR7-associated autoimmunity

open access: yesThe Journal of Clinical Investigation, 2022
Purine nucleoside phosphorylase (PNP) enables the breakdown and recycling of guanine nucleosides. PNP insufficiency in humans is paradoxically associated with both immunodeficiency and autoimmunity, but the mechanistic basis for these outcomes is ...

Identification of Novel HLA-A*24:02-Restricted Epitope Derived from a Homeobox Protein Expressed in Hematological Malignancies. [PDF]

open access: yesPLoS ONE, 2016
The homeobox protein, PEPP2 (RHOXF2), has been suggested as a cancer/testis (CT) antigen based on its expression pattern. However, the peptide epitope of PEPP2 that is recognized by cytotoxic T cells (CTLs) is unknown.

Interaction of deoxycytidine and deoxycytidine analogs in normal and leukemic human myeloid progenitor cells

open access: yesLeukemia Research, 1986
The inhibitory effects of three deoxycytidine analogs, 1-B-D-arabinofuranosylcytosine (Ara-C), 5-aza-2'-deoxycytidine (DAZ) and Ara-5-azacytosine (AAC) were compared with respect to the clonogenic behavior of human promyelocytic leukemic cells (HL-60), a deoxycytidine kinase deficient subvariant (HL-60/Ara-C), and normal human myeloid progenitor cells (

Demethylation by low-dose 5-aza-2′-deoxycytidine impairs 3D melanoma invasion partially through miR-199a-3p expression revealing the role of this miR in melanoma

open access: yesClinical Epigenetics, 2019
Background Efficient treatments against metastatic melanoma dissemination are still lacking. Here, we report that low-cytotoxic concentrations of 5-aza-2′-deoxycytidine, a DNA demethylating agent, prevent in vitro 3D invasiveness of metastatic melanoma ...

Kaiso interacts with p120-catenin to regulate β-catenin expression at the transcriptional level. [PDF]

open access: yesPLoS ONE, 2014
BACKGROUND: We have reported that p120-catenin could regulate β-catenin transcription in lung cancer cells, but the specific mechanism is unclear. METHODS AND RESULTS: In this study, bisulfite sequencing PCR showed that the β-catenin promoter region in ...

IMPDH inhibition enhances cytarabine efficacy in SAMHD1‐expressing leukaemia cells via guanine nucleotide depletion

open access: yesMolecular Oncology, EarlyView.
Cytarabine is a key therapy for acute myeloid leukaemia (AML), but its efficacy is limited by the dNTPase SAMHD1, which hydrolyses its active metabolite. Screening nucleotide biosynthesis inhibitors revealed that IMPDH inhibitors selectively sensitise SAMHD1‐proficient AML cells to cytarabine.

LC-MS-MS quantitative analysis reveals the association between FTO and DNA methylation. [PDF]

open access: yesPLoS ONE, 2017
Fat mass and obesity-associated protein (FTO) is α-ketoglutarate-dependent dioxygenase and responsible for demethylating N6-methyladenosine (m6A) in mRNA, 3-methylthymine (m3T) in single-stranded DNA (ssDNA) and 3-methyluracil (m3U) in single-stranded ...

Time‐restricted feeding prior to Mycobacterium tuberculosis infection reduces tissue CD4+ T cells with limited impact on bacterial clearance

open access: yesFEBS Open Bio, EarlyView.
Time‐restricted feeding (TRF) in mice increased liver fatty acid oxidation and decreased fatty acid biosynthesis. These alterations persisted when TRF was discontinued and the host was infected with Mycobacterium tuberculosis. Pre‐exposure to TRF did not alter tissue (lung and spleen) mycobacterial burden but significantly reduced CD3+ T cells in lungs

Differences in deoxycytidine metabolism in mouse and rat [PDF]

open access: yesBiochemical Journal, 1983
Bone-marrow macrophages from both rat and mouse release deoxycytidine derived from phagocytosed nuclei. Mouse plasma contains no detectable deoxycytidine (less than 0.1 microM), whereas the concentration in rat plasma is 18 microM. Enzyme assays of tissue extracts show that both mouse and rat spleen contain high deoxycytidine kinase activity.
