Integrated analysis of long noncoding RNA interactions reveals the potential role in progression of human papillary thyroid cancer

Cancer Medicine, Volume 7, Issue 11, Page 5394-5410, November 2018., 2018
We collected and analyzed the RNA sequencing profiles of papillary thyroid cancer from The Cancer Genome Atlas. Then, we constructed the ceRNA to reveal the biomarkers in papillary thyroid cancer. Abstract Recent scientific evidence has suggested that long noncoding RNAs (lncRNAs) play an important part in tumorigenesis as an important member of ...

Informationstheoretisches Modell der Carcinogenese

CHIMIA, 1972
The effects of chemical and physical agents on genetic material have been explained by the interaction of the cell with its immediate environment. Another possibility of cancerogenesis stems from the thermodynamic- and information theory-based premise ...

Long‐Term Treatment with Aqueous Garlic and/or Tomato Suspensions Decreases Ehrlich Ascites Tumors

Evidence-Based Complementary and Alternative Medicine, Volume 2014, Issue 1, 2014., 2014
We evaluated the preventive and therapeutic effects of aqueous suspensions of garlic, tomato, and garlic + tomato in the development of experimental Ehrlich tumors in mice. The aqueous suspensions (2%) were administered over a short term for 30 days before tumor inoculation and 12 days afterward, and suspensions at 6% were administered for 180 days ...

Helicobacter pylori and the Prevention of Gastric Cancer

Canadian Journal of Gastroenterology and Hepatology, Volume 18, Issue 5, Page 295-302, 2004., 2004
BACKGROUND: Helicobacter pylori is an important cause of stomach cancer that infects a substantial proportion of the Canadian adult population. H pylori can be detected by noninvasive tests and effectively eradicated by medical treatment. Screening for and treatment of H pylori may represent a significant opportunity for preventive oncology.

Apoptosis, Inflammatory Bowel Disease and Carcinogenesis: Overview of International and Greek Experience

Canadian Journal of Gastroenterology and Hepatology, Volume 17, Issue 4, Page 249-258, 2003., 2003
Apoptosis is critical for organ development, tissue homeostasis, the elimination of abnormal cells and the maintenance of immune homeostasis by variable regulatory mechanisms. The death of T lymphocytes following their activation involves a series of proteases (caspases), which comprise the central executioners of apoptosis.

Hepatitis B Viral Mutants and Their Relevance to the Canadian Health Care System

Canadian Journal of Gastroenterology and Hepatology, Volume 16, Issue 1, Page 45-54, 2002., 2002
Over the past 10 years, an increasing number of mutations in the hepatitis B virus genome have been described. While the majority of these mutations appear to be ‘silent’ or not clinically relevant, some have been described in association with increased severity of disease (core and basic core promoter mutations), evasion of immunological surveillance (
