DNA methylation in thoracic neoplasms

Cancer Letters, 2011
Thoracic neoplasms, which include lung cancers, esophageal carcinoma, and thymic epithelial tumors, are the leading causes of tumor-related death and a major health concern worldwide. The development of neoplasms is a multistep process involving both genetic and epigenetic alterations.

DNA Flow Cytometry of Thyroid Neoplasms

Archives of Otolaryngology - Head and Neck Surgery, 1985
Mechanically dispersed cell suspensions from 23 thyroid lesions were studied by acridine orange flow cytometry. Eight of 14 carcinomas (three papillary, two medullary, two Hürthle cell, and one follicular) manifested abnormal DNA indices ranging from 0.6 to 2.0. Six carcinomas (four papillary and two medullary) were diploid.

Apoptosis Identified by DNA Fragmentation in Epidermal Neoplasms

The Journal of Dermatology, 1995
AbstractIn the previous study, we demonstrated apoptotic cells in basal cell carcinomas by means of terminal deoxynucleotidyl transferase‐mediated dUTP‐biotin nick end labeling (TUNEL). Positive staining cells were present at the peripheries and centers of the nests.

Alterations in chromosomes and DNA content in gynecologic neoplasms

American Journal of Obstetrics and Gynecology, 1969
As a result of chromosome examinations of a variety of normal and neoplastic tissues and the study of their nuclear DNA content, it is possible to make broad generalizations regarding alterations in nuclear genetic material in neoplasia. The work to date in gynecologic neoplasms is reviewed and summarized and the etiologic and diagnostic ramifications ...

DNA content is associated with malignancy of intracranial neoplasms

Clinical Neurology and Neurosurgery, 2013
Flow cytometry has been applied to analyze the DNA-content distribution of tumors, in order to relate this to clinical and biological parameters of tumor behavior. Herewith, we investigated the value of cell cycle analysis in the characterization of intracranial lesions and its possible prognostic role.DNA analysis was performed in tumor samples that ...

Expression of DNA repair gene Ku80 in lymphoid neoplasm

European Journal of Haematology, 2005
Abstract:  Objectives: Ku, a heterodimer of KU70 and Ku80 that binds to double‐strand DNA breaks (DSBs) and activates the catalytic subunit (DNA‐PKcs) when DNA is bound, is essential in DSB repair and V(D)J recombination. Ku80 is a putative tumor suppressor gene that might play an important role in drug resistance. Our aim was to determine the role of

Occurrence of Human Papillomavirus DNA in Primary Lung Neoplasms

Cancer, 1992
The occurrence of human papillomavirus (HPV) DNA in primary lung carcinomas and in squamous metaplasia of the bronchus was studied using in situ hybridization techniques and commercially available biotinylated DNA probes to HPV subtypes 6/11, 16/18, and 31/33/35.

Quantitative DNA analysis of small renal cortical neoplasms

Human Pathology, 1991
DNA aneuploidy is common in large renal cortical neoplasms (RCNs), but the incidence in small RCNs is not known. This study was undertaken to investigate whether the traditional 3.0-cm size distinction between small (benign) and large (malignant) tumors might have an objective correlate in the form of abnormal DNA content. Quantitative DNA analysis was
