In addition multiple isoforms of subtypes have been found which may be due to GENE DUPLICATION.
A usually small, slow-growing neoplasm composed of islands of rounded, oxyphilic, or spindle-shaped cells of medium size, with moderately small vesicular nuclei, and covered by intact mucosa with a yellow cut surface. The tumor can occur anywhere in the gastrointestinal tract (and in the lungs and other sites); approximately 90% arise in the appendix. It is now established that these tumors are of neuroendocrine origin and derive from a primitive stem cell. (From Stedman, 25th ed & Holland et al., Cancer Medicine, 3d ed, p1182)

The incorporation of 5-iodo-2'-deoxyuridine into the DNA of HeLa cells and the induction of alkaline phosphatase activity. (1/9730)

Inhibition of DNA synthesis during the period of exposure of HeLa cells to 5-iodo-2'-deoxyuridine (IUdR) inhibited the induction of alkaline phosphatase activity. This finding, taken together with previous findings that IUdR did not induce alkaline phosphatase activity in the presence of 2-fold molar excess thymidinemonstrated that IUdR incorporation into DNA is correlated with the increase in alkaline phosphatase activity. With the exception of an interim period described in the text, induction of alkaline phosphatase activity was linearly related to medium concentrations of IUdR of up to at least 3 muM. However, the extent of IUdR substitution in DNA did not appear to be related to the degree of enzyme induction. Alkaline phosphatase activity continued to increase at medium concentrations of IUdR from 1 to 3 muM, while little further substitution of DNA occurred.  (+info)

Action of partially thiolated polynucleotides on the DNA polymerase alpha from regenerating rat liver. (2/9730)

The effects of partially thiolated polynucleotides on the DNA polymerase alpha from regenerating rat liver were investigated. The enzyme was isolated from the nuclear fraction essentially according to the method of Baril et al.; it was characterized as the alpha polymerase on the basis of its response to synthetic templates and its inhibition with N-ethylmaleimide. Although polycytidylic acid had no effect on the DNA polymerase alpha either as a template or as an inhibitor, partially thiolated polycytidylic acid (MPC) was found to be a potent inhibitor, its activity being directly related to its extent of thiolation (percentage of 5-mercaptocytidylate units in the polymer). In comparison, the DNA polymerase beta which was purified from normal rat liver nuclear fraction, was much less sensitive to inhibition by MPC. Analysis of the inhibition of the alpha polymerase by the method of Lineweaver and Burk showed that the inhibitory action of MPC was competitively reversible with the DNA template, but the binding of the 7.2%-thiolated MPC to the enzyme was much stronger than that of the template (Ki/Km less than 0.03). Polyuridylic acid as such showed some inhibitory activity which increased on partial thiolation, but the 8.4%-thiolated polyuridylic acid was less active than the 7.2% MPC. When MPC was annealed with polyinosinic acid, it lost 80% of its inhibitory activity in the double-stranded configuration. However, 1 to 2%-thiolated DNA isolates were significantly more potent inhibitors than were comparable (1.2%-thiolated) MPC and showed competitive reversibility with the unmodified (but "activated") DNA template. These results indicate that the inhibitory activities of partially thiolated polynucleotides depend not only on the percentage of 5-mercapto groups but also on the configuration, base composition, and other specific structural properties.  (+info)

Blood thymidine level and iododeoxyuridine incorporation and reutilization in DNA in mice given long-acting thymidine pellets. (3/9730)

A long-acting thymidine pellet consisting of 190 mg of cholesterol and 60 mg of thymidine has been developed for the study of thymidine metabolism and reutilization in vivo. Implantation of such a pellet s.c. in adult mice will maintain the blood plasma concentration of thymidine at levels between 40 and 8 X 10(-6) M, which are from 36 to 7 times those of normal mice, for periods up to 48 hr. During this period, in vivo uptake and reutilization of [125I]iododeoxyuridine, a thymidine analog, into intestinal and tumor DNA were almost completely suppressed. While iododeoxyuridine reutilization is not large in normal proliferative tissue even in the absence of pellet implants, reutilization of over 30% was measured in large, rapidly growing ascites tumors. The inhibition of iododeoxyuridine incorporation by elevated thymidine blood levels is directly proportional to serum concentration. This appears to be due to a thymidine pool in rapid equilibrium with blood thymidine. This pool is at least 10 times larger than the 4-nmole pool of extracellular thymidine.  (+info)

The effects of estrogens and antiestrogens on hormone-responsive human breast cancer in long-term tissue culture. (4/9730)

We have established or characterized six lines of human breast cancer maintained in long-term tissue culture for at least 1 year and have examined these lines for estrogen responsiveness. One of these cell lines, MCF-7, shows marked stimulation of macromolecular synthesis and cell division with physiological concentrations of estradiol. Antiestrogens are strongly inhibitory, and at concentrations greater than 3 X 10(-7) M they kill cells. Antiestrogen effects are prevented by simultaneous treatment with estradiol or reversed by addition of estradiol to cells incubated in antiestrogen. Responsive cell lines contain high-affinity specific estradiol receptors. Antiestrogens compete with estradiol for these receptors but have a lower apparent affinity for the receptor than estrogens. Stimulation of cells by estrogens is biphasic, with inhibition and cell death at concentrations of 17beta-estradiol or diethylstilbestrol exceeding 10(-7) M. Killing by high concentrations of estrogen is probably a nonspecific effect in that we observe this response with 17alpha-estradiol at equivalent concentrations and in the otherwise unresponsive cells that contain no estrogen receptor sites.  (+info)

The effects of glucocorticoids and progesterone on hormone-responsive human breast cancer in long-term tissue culture. (5/9730)

Glucocorticoids, at physiological concentration, inhibit cell division and thymidine incorporation in three lines of human breast cancer maintained in long-term tissue culture. At steroid concentrations sufficient to inhibit thymidine incorporation 50%, little or no effect is seen on protein synthesis 48 hr after hormone addition. All three of these lines are shown to have glucocorticoid receptors demonstrable by competitive protein binding assays. Receptors are extensively characterized in one line by sucrose density gradient analysis and binding specificity studies. Good correlation between receptor-binding specificity and biological activity is found except for progesterone, which binds to glucocorticoid receptor but is noninhibitory. Cross-competition and quantification studies demonstrate a separate receptor for progesterone. This receptor has limited binding specificities restricted largely to progestational agents, whereas the glucocorticoid receptor bound both glucocorticoids and progesterone. Two other human breast cancer lines neither contain glucocorticoid receptor nor are inhibited by glucocorticoids. It is concluded that in some cases glucocorticoids can directly limit growth in human breast cancer in vitro without requiring alterations in other trophic hormones.  (+info)

The effects of androgens and antiandrogens on hormone-responsive human breast cancer in long-term tissue culture. (6/9730)

We have examined five human breast cancer cell lines in continuous tissue culture for androgen responsiveness. One of these cell lines shows a 2- to 4-fold stimulation of thymidine incorporation into DNA, apparent as early as 10 hr following androgen addition to cells incubated in serum-free medium. This stimulation is accompanied by an acceleration in cell replication. Antiandrogens [cyproterone acetate (6-chloro-17alpha-acetate-1,2alpha-methylene-4,6-pregnadiene-3,20-dione) and R2956 (17beta-hydroxy-2,2,17alpha-trimethoxyestra-4,9,11-triene-1-one)] inhibit both protein and DNA synthesis below control levels and block androgen-mediated stimulation. Prolonged incubation (greater than 72 hr) in antiandrogen is lethal. The MCF- cell line contains high-affinity receptors for androgenic steroids demonstrable by sucrose density gradients and competitive protein binding analysis. By cross-competition studies, androgen receptors are distinguishable from estrogen receptors also found in this cell line. Concentrations of steroid that saturate androgen receptor sites in vitro are about 1000 times lower than concentrations that maximally stimulate the cells. Changes in quantity and affinity of androgen binding to intact cells at 37 degrees as compared with usual binding techniques using cytosol preparation at 0 degrees do not explain this difference between dissociation of binding and effect. However, this difference can be explained by conversion of [3H]-5alpha-dihydrotestosterone to 5alpha-androstanediol and more polar metabolites at 37 degrees. An examination of incubation media, cytoplasmic extracts and crude nuclear pellets reveals probable conversion of [3H]testosterone to [3H]-5alpha-dihydrotestosterone. Our data provide compelling evidence that some human breast cancer, at least in vitro, may be androgen dependent.  (+info)

Tissue pharmacokinetics, inhibition of DNA synthesis and tumor cell kill after high-dose methotrexate in murine tumor models. (7/9730)

In Sarcoma 180 and L1210 ascites tumor models, the initial rate of methotrexate accumulation in tumor cells in the peritoneal cavity and in small intestine (intracellularly) after s.c. doses up to 800 mg/kg, showed saturation kinetics. These results and the fact that initial uptake in these tissues within this dosage range was inhibited to the expected relative extent by the simultaneous administration of leucovorin suggest that carrier mediation and not passive diffusion is the major route of drug entry at these extremely high doses. Maximum accumulation of intracellular drug occurred within 2 hr and reached much higher levels in small intestine than in tumor cells at the higher dosages. At a 3-mg/kg dose of methotrexate s.c., intracellular exchangeable drug levels persisted more than four times longer in L1210 cells than in small intestine, but differences in persistence (L1210 cell versus gut) diminished markedly with increasing dosage. At 96 mg/kg, the difference in persistence was less than 2-fold. In small intestine and L1210 cells, theduration of inhibition of DNA synthesis at different dosages correlated with the extent to which exchangeable drug was retained. Toxic deaths occurred when inhibition in small intestine lasted longer than 25 to 30 hr. Recovery of synthesis in small intestine and L1210 cells occurred synchronously and only below dosages of 400 mg/kg. Within 24 hr after dosages of greater than 24 mg/kg, the rate of tumor cell loss increased to a point characterized by a single exponential (t1/2=8.5 hr). The total cell loss, but not the rate of cell loss, was dose dependent.  (+info)

Ambiguity of the thymidine index. (8/9730)

The observed thymidine indices of seven experimental tumor lines are compared as a function of duration of emulsion exposure. The effects of dose level of tritiated thymidine and background threshold are also evaluated. The results indicate that an arbitrary high background threshold discriminates against "lightly" labeled cells at short periods of exposure but that the chosen threshold becomes less critical with longer exposure. The observed thymidine index increases with increasing duration of emulsion exposure but appears to approach a plateau for all tumor systems. The "thymidine index curves" are significantly different for each tumor. There is an inverse relationship between the dose of tritiated thymidine and the duration of exposure required to recognize the same fraction of cells as labeled in a given tumor. Similar experimental conditions do not necessarily guarantee a valid basis for comparison of observed thymidine indices among tumors.  (+info)

The detection of tumor-derived cell-free DNA in plasma is one of the most promising directions in cancer diagnosis. The major challenge in such approach is how to identify the tiny amount of tumor DNAs out of total cell-free DNAs in blood. Here we propose an ultrasensitive cancer detection method, termed CancerDetector, using the DNA methylation profiles of cell-free DNAs. The key of our method is to probabilistically model the joint methylation patterns of multiple adjacent CpG sites on an individual sequencing read, in order to exploit the pervasive nature of DNA methylation for signal amplification. Therefore, CancerDetector can sensitively identify a trace amount of tumor cfDNAs in plasma, at the level of individual reads. We evaluated CancerDetector on the simulated data, and showed a high concordance of the predicted and true tumor burden. Testing CancerDetector on real plasma data demonstrated its high sensitivity and specificity in detecting tumor DNAs. In addition, the predicted tumor ...
However, ASCO also acknowledges that emerging technologies, like genomic profiling for low penetrance genetic variants (markers of very low disease risk), may be appropriate for some patients who do not have a personal or family history that suggests a higher risk of cancer. People may undergo genetic testing using direct-to-consumer (DTC) tests, but they may ask their health care providers for help in interpreting the test results and obtaining follow-up care. For any genetic test, ASCO urges doctors and other health care providers to recommend follow-up care that is based on established cancer risk factors such as family history, behavioral factors, environmental exposures, and scientifically-validated tests for cancer risks.. ASCO further states that although the list of genes for cancer susceptibility syndromes continues to grow, the ever-changing nature of the field highlights the importance of getting genetic counseling both before and after doing genetic testing.

Plasma DNA rose before there was clinical evidence of recurrence in 67 percent of patients, versus 17 percent of patients measured for CEA ...
A recent review in Oncogene discusses how fasting may help patients who have been diagnosed with cancer. This is interesting, because at the moment most people are advised to eat extra calories and proteins while undergoing cancer treatments. It turns out that in animals fasting changes the physiology of the body and this can help protect normal cells from the damaging effects of anti-cancer agents. The amazing thing is that cancer cells are abnormal and dont get the same protection, so fasting seems to be a way to help normal cells and not help the targets of the treatment. It More ,. ...
article{28d6110c-5d57-42d8-9243-f7ea1c6d6398, abstract = {This analysis of DNA-ploidy heterogeneity in advanced gastric carcinomas is consistent with the hypothesis of the emergence of a single aneuploid cell clone as a crucial mechanism in the progression from early gastric carcinoma to advanced gastric cancer. The prognostic value of DNA-ploidy in gastric cancers has been a matter of controversy. Tumour DNA-ploidy heterogeneity, the presence within the same tumour of multiple stemlines differing in DNA content, has been described in various tumours including gastric cancers. The occurrence of such heterogeneity has been accepted as an explanation for the divergent DNA-ploidy results in this type of tumours. A previous study of early gastric cancers suggested that in pure diploid superficial carcinomas, genetic instability might lead to a cell clone which has undergone a ploidy shift and is more aggressive. If so, this would initially result in DNA-ploidy heterogeneity. Proliferative dominance ...

DNA vaccination holds great promise for the prevention and treatment of cancer and infectious diseases. However, the clinical ability of DNA vaccines is still controversial due to the limited immune response initially observed in humans. We hypothesized that electroporation of a plasmid encoding the HIV-1 Gag viral capsid protein would enhance cancer DNA vaccine potency. DNA electroporation used to deliver plasmids in vivo, induced type I interferons, thereby supporting the activation of innate immunity. The coadministration of ovalbumin (OVA) and HIV-1 Gag encoding plasmids modulated the adaptive immune response. This strategy favored antigen-specific Th1 immunity, delayed B16F10-OVA tumor growth and improved mouse survival in both prophylactic and therapeutic vaccination approaches. Similarly, a prophylactic DNA immunization against the melanoma-associated antigen gp100 was enhanced by the codelivery of the HIV-1 Gag plasmid. The adjuvant effect was not driven by the formation of HIV-1 Gag ...

Background: DNA polymerases (Pols) represent potential candidates for cancer genes because of their central functions in DNA metabolism. Defects of some DNA Pols have shown cancer associations, but data on DNA polymerase (Pol) ε is limited. Materials and Methods: Twenty-four human breast cancer DNA samples and four control DNA samples were examined for possible mutation in the entire coding region of the 55 kDa small subunit of the human DNA Pol ε gene using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) analysis of the DNA and sequence analysis. In addition, 20 control DNAs were studied with PCR-SSCP for the end of intron 18 and exon 19 region. Results: An AATT deletion was found at one location in intron 18 in 2 out of the 24 breast cancer cases (8%), but in none of the control cases. In addition, a single base transition was found in the cancer DNAs in intron 14, but the same changes were also found in the control DNAs, suggesting polymorphism. Conclusion: ...
|i|Background|/i|: C-Myc, a well-known oncogene located on 8q24.12–q24.23, is often amplified and over-expressed in both primary and metastasizing colorectal cancer. In addition, PRL-3 (also known as PTP4A3), a tyrosine phosphatase located on 8q24.3, is amplified in colorectal cancer metastasis. Beside PRL-3 and c-myc, other oncogenes located on the 8q23–24 region might be involved in this process. Therefore, the present study aims to correlate DNA copy number status of a series of genes at 8q23–24 in colorectal cancer at high resolution in correlation to metastatic disease. |i|Materials and Methods|/i|: Thirty-two cases of colorectal cancer, 10 stage B1, 10 B2 and 12 D (Astler–Coller) with their corresponding liver metastasis and one colorectal cell line (colo205, previously analyzed by array-CGH), were included in this study. A chromosome 8 specific MLPA probe mixture was used to analyze the presence of DNA copy number changes. The probe mixture contained 29 probes covering
BACKGROUND: Wilms tumour (WT) is the most common solid tumour affecting young children. Its histological diversity leads to difficulties in predicting the outcome. MATERIALS AND METHODS: Image analysis cytometry and immunohistochemistry with a selected panel of antibodies were performed in 23 cases of WT considered of intermediate risk according to the revised International Society of Pediatric Oncology (SIOP) working classification of renal tumours of childhood. In this series, a tumour was considered aggressive according to its propensity for metastases or its recurrence. RESULTS: Out of the 14 non-aggressive WT, 4 were found to be diploid and 10 were aneuploid including 6 that were heterogeneous for DNA-ploidy. All the tumours presented a low proliferative index and were negative for p53 and p57(kip2) immunostaining. Out of the 9 aggressive tumours, all were aneuploid and 4 were found to be heterogeneous for DNA-ploidy. They all presented a high degree of cell proliferation and 7 w

Background: DNA ploidy has been shown to have prognostic significance in patients with breast cancer. Studies in the past have mainly utilized flow cytometry (FCM) for measuring DNA ploidy. However FCM has several disadvantages, the instrument cannot distinguish benign from malignant cells and it cannot be performed on small tumor samples. The relationship between DNA ploidy and biomarker expression in breast cancer has not been well studied. Recently, gene expression analysis has demonstrated distinct subtypes of breast cancer. Expression of ER, PR and Her2 by IHC has been used as a surrogate tool for the molecular classification of breast cancer. Aim: To determine the relationship between DNA ploidy, biomarkers (ER, PR, HER2, Ki67 and p53) expression and molecular subtypes of invasive breast cancer (IBCA) using image analysis.. Design: DNA analysis was performed on Feulgen stained sections from the same tumor block used for biomarker analysis. DNA indices and ploidy were analyzed using the ...

Aneuploidy is a well recognised feature of human tumours, but the investigation of its biological and clinical significance has been hampered by technological constraints. Quantitative DNA analysis reflects the total chromosomal content of tumour cells and can now be determined rapidly and reliably using flow cytometry; this has resulted in renewed interest in its potential clinical applications. This article reviews the accumulating evidence that tumour ploidy reflects the biological behaviour of a large number of tumour types and that diploid tumours in particular have a relatively good prognosis. The measurement of tumour ploidy is likely to become a valuable adjunct to the clinical and histopathological assessment of cancers.. ...

Assay of cell-free DNA in blood offers an approach to assessment of tumor DNA. We sought to determine whether Epstein-Barr virus (EBV) DNA in cell-free blood is also a good surrogate for the presence of tumor DNA in children with Hodgkin lymphoma, as it is in adults, and whether it correlates with pediatric outcomes. Pediatric patients enrolled in a Childrens Oncology Group trial (AHOD0031) were studied at baseline and at 8 days after the initiation of treatment. At baseline, EBV DNA in cell-free blood correlated with the presence of EBV in tumor, and EBV DNA 8 days after the initiation of therapy predicted inferior event-free survival ...

Holden thinks more data will be required for a firm determination. The data need to go 15 years out to make recommendations confidently, and they dont, he says. Its an interim analysis and the task force is drawing its own conclusions. Most of its done with different kinds of health care systems and different types of populations and there are huge cultural differences.. For instance, he says, If you offer surveillance to a group of patients in Scandinavia for whatever criteria you think are appropriate for that recommendation, about 50 percent of them will take that option. In the United States, its about 9 percent.. New technology may ride to the rescue. For example, the PCF wants to see the development of a urine test resulting from specific prostate cancer DNA fusions in 2005 at the University of Michigan.

All eligible studys quality assessment refers to the European Lung Cancer Party quality scale. |i|Results|/i|: Combined analysis showed that |i|ras|/i| oncogene mutation was a poor impact on survival in AML patients (Hazard ratios (HRs): 1.50, 1.19-1.89, |i|p|/i| |0.001). |i|Nras|/i| gene mutation was a worse survival marker in AML (HR: 1.97, 95% CI: 1.35-2.89, |i|p|/i| |0.001) and |i|Kras|/i| gene mutations was no significance (HR: 1.32, 95% CI: 0.83-2.09, |i|p|/i| =0.24) by stratified analysis. In the analysis of age bracket, adults with |i|ras|/i| gene mutation had an unfavorable survival (HR: 1.55, 95% CI: 1.19-2.21, |i|p|/i| =0.01) and
Flow cytometry is more and more widely used for investigations of cell death, predominantly in the study of DNA degradation in cells dying by apoptosis. There are different interpretations of changes observed in DNA histograms of these cells. We describe an approach based on extraction of chromatin degradation products from fixed cells and subsequent staining with DNA specific dyes. Apoptotic cells containing fragmented DNA are observed in , 2C DNA region of DNA histograms. DNA histograms of irradiated thymocytes dying in vitro and stained without extraction of fragmented DNA do not differ from control. Under the same staining conditions DNA histograms of lymphocytes dying in thymus of irradiated animals reveal fluorescent material in , 2C DNA region, most likely due to formation of apoptotic bodies (cell fragments, some of them contain fragments of nuclei). Similar changes are observed in thymocytes dying upon glucocorticoid treatment. Our present results and other data indicate that reduced ...
LOH and microsatellite alterations were observed in biopsy specimens from both current and former smokers, but no statistically significant differences were observed between the two groups. Among individuals with a history of smoking, 86% demonstrated LOH in one or more biopsy specimens, and 24% showed LOH in all biopsy specimens. About half of the histologically normal specimens from smokers showed LOH, but the frequency of LOH and the severity of histologic change did not correspond until the carcinoma in situ stage. A subset of biopsy specimens from smokers that exhibited either normal or preneoplastic histology showed LOH at multiple chromosomal sites, a phenomenon frequently observed in carcinoma in situ and invasive cancer. LOH on chromosomes 3p and 9p was more frequent than LOH on chromosomes 5q, 17p (17p13; TP53 gene), and 13q (13q14; retinoblastoma gene). Microsatellite alterations were detected in 64% of the smokers. No genetic alterations were detected in nonsmokers. Conclusions: ...
828 Small and large-scale chromosomal aberrations, including amplifications, deletions, and rearrangements, are commonly seen in solid tumors. In human colorectal cancer (CRC), amplification of chromosome regions 20q, 8q, 13q, 7p, 12p, and loss of 18q, 8p, 17p, 4p, and 15q are frequently observed. These regions harbor oncogenes, tumor suppressors, and DNA repair genes that are known to be involved in the etiology of the disease. A combined, high-resolution gene expression and DNA copy number approach has been applied to test the hypothesis that a more comprehensive measure of the genetic damage in CRC will reveal novel molecular targets. Here, microarrays consisting of ∼35,000 spotted oligonucleotides have been utilized to examine both gene expression and DNA copy number changes in primary colorectal tumors from patients with stage II-IV disease. A colorectal cancer tissue array containing approximately 100 CRC samples has been constructed for use in validation studies. To date, 50 primary CRC ...
TY - JOUR. T1 - Cell cycle analysis using flow cytometry. AU - Gray, J. W.. AU - Dolbeare, F.. AU - Pallavicini, M. G.. AU - Beisker, W.. AU - Waldman, F.. PY - 1986/1/1. Y1 - 1986/1/1. N2 - This manuscript reviews the utility of flow cytometry for the study of cell proliferation. The applications of univariate DNA distribution analysis to cytokinetic studies of asynchronous and perturbed cell populations are discussed briefly. The newly developed technique for simultaneous flow cytometric measurement of cellular DNA content and amount of incorporated bromodeoxyuridine is discussed in more detail. The cytochemistry required for this analysis is reviewed as are its applications to: (a) determination of the fractions of cells in the G1-, S- and G2 + M phases of the cell cycle; (b) determination of the G1-, S- and G2 + M phase durations and dispersions and growth fraction for asynchronous cells; (c) detection of ara-C resistant cells present at low frequency in an otherwise sensitive population; ...

New revolutionary tests that can detect stray cancer cells in the blood are emerging as the latest and most innovative way to detect the presence of cancer much earlier than possible with previous mainstream testing.. Painful biopsies, visible signs of disease, mammogram, colonoscopy, and surgery have been the mainstay for screening and diagnosing cancer cells and determining treatment options. These methods have drawbacks, for example, the samples arent enough to identify the genes or pathways that command growth mechanisms and are often unavailable for an oncologist to examine between the time span of the test and the patients appointment.. Stanford University School of Medicine has developed the cancer personalized profiling by deep sequencing, CAPP-Seq, an new test for early detection that is unlike any other because it explores DNA to identify stray cancer cells as they float in the bloodstream. Remarkably, it can detect a single cancerous molecule of cancer DNA out of 10,000 healthy ...
The cell-free DNA (cfDNA) is always present in plasma, and it is biomarker of growing interest in prenatal diagnostics as well as in oncology and transplantology for therapy efficiency monitoring. But does this cfDNA have a physiological role? Here we show that cfDNA presence and clearance in plasma of healthy individuals plays an indispensable role in immune system regulation. We exposed THP1 cells to healthy individuals plasma with (NP) and without (TP) cfDNA. In cells treated with NP, we found elevated expression of genes whose products maintain immune system homeostasis. Exposure of cells to TP triggered an innate immune response (IIR), documented particularly by elevated expression of pro-inflammatory interleukin 8. The results of mass spectrometry showed a higher abundance of proteins associated with IIR activation due to the regulation of complement cascade in cells cultivated with TP. These expression profiles provide evidence that the presence of cfDNA and its clearance in plasma of healthy
In one case (#1251), SNV observed in the tumor DNA were not detected in plasma DNA. In another case (#1559), SNV were barely detectable (VAF of 0.5% for two variants). Of note, both cases displayed limited disease (stage I or II) and normal lactate dehydrogenase levels, indicating that the amount of tumor-specific circulating cfDNA is at least partially related to tumor burden. Despite a low amount of circulating DNA extracted from plasma for cases #1251 and #1559, we obtained adequate sequencing quality and depth (the overall number of reads sequenced with mutated targets was 4,685 and 51,195 respectively; Table 1), indicating that in some rare cases, tumor-specific cfDNA is absent or beneath the level of sensitivity of the NGS method used. Of note, in case #1631 characterized by limited stage I disease, SNV were detected with a mean VAF of 5.2% in plasma DNA, as compared to a mean VAF of 34.6% in the tumor DNA (Table 1). In contrast, cases #1639 and #1768 (both with stage IV disease and ...
