Tumorigenesis is the process involved in the production of a new tumor or tumors.
Smoking has long been the biggest cause of cancer in the United States, but obesity, now the second leading cause, has been gaining ground.
Activins are proteins involved in a number of important biological functions, including the regulation of the menstrual cycle, cell proliferation, differentiation, apoptosis, metabolism, homeostasis, immune response, wound repair, and endocrine function.
In 1982, researchers reported a link between chronic gastritis and stomach bacterium Helicobacter pylori, triggering a flurry of research into this newly-identified pathogen.
Johns Hopkins Kimmel Cancer Center researchers say a new study of clusters of mouse cells known as "organoids" has significantly strengthened evidence that epigenetic changes, common to aging, play a essential role in colon cancer initiation.
Of all gastrointestinal cancers, pancreatic cancer is one of the most aggressive. Because of this, it has a very low 5-year survival rate of just 5% and a median survival time below 6 months. Additionally, treatment is difficult, with only surgery shown to provide a cure. However, the vast majority of patients have tumors that cannot be removed surgically or their cancer is too advanced or spread too far to be treatable.
The abnormal expression of different classes of molecules is known to be linked to various types of cells becoming cancerous.
In this interview, Émilie Beaulieu Ouellet, Application Scientist for life science imaging at Photon Etc talks to New-Medical about their range of preclinical infrared imagers and how they can allow cancer detection.
CDK1 is a "normal" protein - its presence drives cells through the cycle of replication. And MHC Class I molecules are "normal" as well - they present bits of proteins on the surfaces of cells for examination by the immune system.
"With our study we originally wanted to study the role of bacteria in the intestines in the development of intestinal inflammation," explains Professor Dirk Haller from the Department of Nutrition and Immunology at the Weihenstephan Science Centre of the TUM.
'Chromosomal catastrophes' have been found to occur along the evolutionary timeline of colorectal cancer development, according to new research led by Queen Mary University of London.
The regulatory protein c-MYC plays an important role in promoting the development of many types of tumors. c-MYC is a transcription factor that controls the activity of large numbers of genes involved in cell division, and its overexpression leads to excessive cell proliferation.
Researchers have discovered how a molecule can help prevent certain types of brain tumors by recognizing and 'disarming' harmful proteins that cause them.
Neutrophils-;short-lived, highly mobile and versatile-;outnumber all other immune cells circulating through the blood stream.
Cancer researchers struggle to identify tumor cells that are interspersed within nonmalignant tissues because tumor cells exploit the tissue environment and monopolize available resources to continue growing.
Johns Hopkins researchers in collaboration with Insilico Medicine, a biotechnology company based in Rockville Maryland, identify that silencing of the GULP1 gene expression by methylation plays an important role in ovarian carcinogenesis.
Scientists headed by ICREA researcher Angel R. Nebreda at the Institute for Research in Biomedicine (IRB Barcelona) report a new mechanism that contributes to the development of inflammation-associated colon cancer and points to new therapeutic targets. The study has been published in the journal EMBO Molecular Medicine.

Researchers from Osaka University have discovered how precancerous cells spread to normal tissue and cause cancer.
Testicular germ cell cancer, a disease that is rare but growing in incidence in men in the United States, is considered to be among the most curable of solid tumors. Now researchers from the University of North Carolina Lineberger Comprehensive Cancer Center and a consortium of institutions have discovered the genetic and genomic characteristics that define the disease.
Publication in Nature Cell Biology: researchers at the Université libre de Bruxelles, ULB define for the first time the mechanisms responsible for the mammary gland development.
