Changes in the nuclear distribution of DNA polymerase alpha and PCNA/cyclin during the progress of the cell cycle, in a cell-free extract of Xenopus eggs [PDF]

open access: yes, 1989
The nuclear distribution of DNA polymerase alpha and PCNA/cyclin in embryonic nuclei has been investigated, in a cell-free extract of Xenopus eggs that recapitulates a basic cell-cycle in vitro, by indirect immunofluorescence microscopy.

Identifying a role for Ciz1 in the DNA damage response [PDF]

open access: yes, 2011
In proliferating cells, cell cycle arrest and DNA repair are induced upon detection of DNA damage. The DNA damage response (DDR) to double strand DNA breaks is mediated by phosphatidylinositol 3-kinase-like protein kinases (PIKKs), which propagate DDR ...

Ciz1 cooperates with cyclin-A-CDK2 to activate mammalian DNA replication in vitro [PDF]

open access: yes, 2010
Initiation of mammalian DNA replication can be reconstituted from isolated G1-phase nuclei and cell extracts, supplemented with cyclin-dependent protein kinases (CDKs).

Evaluating the efficacy of DNA repair biomarkers to assess human cell response to chemotherapy using imaging flow cytometry [PDF]

open access: yes, 2013
This thesis was submitted for the degree of Doctor of Philosophy and awarded by Brunel University.Chemotherapy and radiotherapy are widely accepted as common forms of treatment for cancers. The majority of cancer patients receive chemotherapy alone or in

Whole genome deep sequencing analysis of cell-free DNA in samples with low tumour content

open access: yesBMC Cancer, 2022
Background Circulating cell-free DNA (cfDNA) in the plasma of cancer patients contains cell-free tumour DNA (ctDNA) derived from tumour cells and it has been widely recognized as a non-invasive source of tumour DNA for diagnosis and prognosis of cancer ...

Endogenous cell-free DNA in fetal bovine serum introduces artifacts to in vitro cell-free DNA models

open access: yesBioTechniques, 2022
Cell-free DNA (cfDNA) is of growing clinical and research significance. In vitro cfDNA models are a useful tool in cfDNA research; however, artifacts in these models may have implications for the interpretation of new and published data.

The Impact of Pre-transplant Cell-free DNA Levels on Leukemia Relapse and Transplant-related Complications in Allogeneic Hematopoietic Stem Cell Transplant Recipients

open access: yesBalkan Medical Journal, 2020
Background: Cell-free DNA, which may be considered as “liquid” biopsy, may serve as a diagnostic and prognostic marker not only in hematological malignancies but in solid tumors as well.

Comparison of methods for the isolation of cell-free DNA from cell culture supernatant

open access: yesTumor Biology, 2020
In vitro characterization of cell-free DNA using two-dimensional cell culture models is emerging as an important step toward an improved understanding of the physical and biological characteristics of cell-free DNA in human biology.

Study the Role of Cell Free DNA in the Diagnosis of Hepatocellular Carcinoma, an Egyptian Study

open access: yesAsian Pacific Journal of Cancer Biology, 2022
Background and objective: Hepatocellular carcinoma (HCC) is a primary malignancy of the liver. Since the conventional tissue biopsy and AFP have limited value, a new promising diagnostic method” liquid biopsy” has emerged.

Circulating biomarkers to monitor cancer progression and treatment

open access: yesComputational and Structural Biotechnology Journal, 2016
Tumor heterogeneity is a major challenge and the root cause of resistance to treatment. Still, the standard diagnostic approach relies on the analysis of a single tumor sample from a local or metastatic site that is obtained at a given time point. Due to
