Cytosine-to-Uracil Deamination by SssI DNA Methyltransferase [PDF]

open access: yes, 2013
The prokaryotic DNA(cytosine-5)methyltransferase M.SssI shares the specificity of eukaryotic DNA methyltransferases (CG) and is an important model and experimental tool in the study of eukaryotic DNA methylation.

Restriction enzymes used in this study.

open access: yes, 2021
The names and recognition sequences (restriction sites) of the restriction enzymes that were used to produce experimental dually labeled DNA barcodes. Note that the complement recognition sequences of each listed recognition sequences is a palindromic ...

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.

On the DNA cleavage mechanism of Type I restriction enzymes [PDF]

open access: yes, 2017
Although the DNA cleavage mechanism of Type I restriction-modification enzymes has been extensively studied, the mode of cleavage remains elusive. In this work, DNA ends produced by EcoKI, EcoAI and EcoR124I, members of the Type IA, IB and IC families ...

PCR-RFLP diagnostic method for identifying Globodera species in Slovenia [PDF]

open access: yes, 2011
Species identification within the genus Globodera is based on the morphological and morphometrical characters of the cysts and second stage juveniles, and these are included in the majority of identification keys.

Testing the usage of ITS2 and 28S-D2 markers in identifying some species of Ammophila, Prionyx, and Sphex genera (Hymenoptera: Sphecidae)

open access: yesJournal of New Results in Science, 2015
In addition to traditional methods, investigation of rDNA gene regions with molecular techniques is widely used to identify insect taxa. In this study, the usability of the primers (TrITS2, 28S-D2) belonging to second expansion segment (D2) of the 28S ...

Hijacking emergency granulopoiesis: Neutrophil ontogeny and reprogramming in cancer

open access: yesMolecular Oncology, EarlyView.
Neutrophils are highly plastic innate immune cells; their functions in cancer extend beyond the tumour microenvironment. This Review summarises current understanding of neutrophil maturation and heterogeneity and highlights tumour‐induced granulopoiesis as a systemic programme that expands immature, immunosuppressive neutrophils via tumour‐derived ...

Loss of IGF‐1R impairs DNA‐PKcs recruitment to chromatin leading to defective end‐joining

open access: yesMolecular Oncology, EarlyView.
IGF‐1R promotes radioresistance by facilitating DNA‐PKcs recruitment to chromatin, enabling non‐homologous end‐joining (NHEJ) repair of double‐strand breaks. Inhibition or loss of IGF‐1R disrupts this recruitment to damage sites, driving compensatory reliance on microhomology‐mediated end‐joining (MMEJ) repair.
