Tumorigenesis is the process involved in the production of a new tumor or tumors.

LMU researchers reveal role of mutations in development of Ewing's sarcoma

Researchers from Ludwig-Maximilians-Universitaet in Munich have elucidated at the molecular level how an otherwise innocuous inherited mutation that is quite common in European populations interacts with a spontaneous somatic mutation to promote the development of Ewing's sarcoma.

Researchers identify genetic abnormalities that lead to skin SCC

Squamous cell carcinoma (SCC) of the skin is one of the most frequent cancers in humans affecting more than half million new persons every year in the world. The transformation of a normal cell to a cancer cell is caused by an accumulation of genetic abnormalities in the progeny of single cells. The spectrum of genetic anomalies found in a variety of human cancers have been described.

Study offers new way to suppress growth factors related to cancer cell proliferation

Cancer cells need life-essential molecules to proliferate. These so-called growth factors are activated by ectodomain shedding of precursor proteins on the outside of the plasma membrane, mainly carried out by three human cleavage enzymes. A pharmaceutical blocking of these enzymes could hinder cancer from growing but would also inhibit other life-essential processes.

Four young scientists named recipients of Damon Runyon-Sohn Pediatric Cancer Research Fellowship Award

The Damon Runyon Cancer Research Foundation has named four outstanding young scientists as recipients of the prestigious Damon Runyon-Sohn Pediatric Cancer Research Fellowship Award, committing nearly $875,000 to help address a critical shortage of funding for pediatric cancer research.

Defects in mitochondria play key role in transition of normal cells to cancerous cells

Cancer cells defy the rules by which normal cells abide. They can divide without cease, invade distant tissues and consume glucose at abnormal rates.

New species of tRNA-derived small RNAs contribute to cell proliferation in cancer

Since their discovery in the 1950s, transfer RNAs (tRNAs) have been best known for their role in helping the cell make proteins from messenger RNA templates. However, recent studies have led to a previously-unsuspected concept that tRNAs are not always the end product; namely, they further serve as a source of small RNAs.

New discovery could lead to personalized treatment for colon cancer

A UNC Lineberger Comprehensive Cancer Center discovery of just how a certain tumor suppressor molecule works to prevent tumor growth could lead to a personalized treatment approach for colon cancer.

Caltech chemists develop new sensitive technique that can detect colorectal cancer in tissue samples

Chemists at Caltech have developed a new sensitive technique capable of detecting colorectal cancer in tissue samples -- a method that could one day be used in clinical settings for the early diagnosis of colorectal cancer.

Cell fusion triggers multiple genetic changes that convert normal cells to cancer cells

Although there is no one established universal cause of cancer, genetic changes are central to its development. The accumulation of spontaneous genetic changes, or mutations, that occur when cells divide can be hastened by exposure to carcinogens such as cigarette smoke (lung cancer) and infectious agents such as the papillomavirus (cervical cancer).

Study reveals new molecular mechanism that helps protect genome from harmful effect of UV radiations

Researchers have uncovered a new molecular mechanism whereby human cells protect their genome from the detrimental effect of UV radiation and govern DNA replication in cellular mitosis, which, when it malfunctions, leads to harmful results.

$Bone-marrow-derived MSCs can promote fracture healing$

Bone-marrow-derived MSCs can promote fracture healing

Mesenchymal stem cells (MSCs) have been transplanted to successfully treat a variety of diseases and conditions. The benefit of using MSCs is their ability to self-renew and differentiate into a variety of specialized cell types, such as osteoblasts (cells contributing to bone formation), chondrocytes (cartilage cells), adipocytes (fat cells), myocardiocytes (the muscle cells that make up the cardiac muscle), and neurons (nervous system cells).

IMIM researchers identify new way of treating colorectal cancer

Researchers at the Institut Hospital del Mar d'Investigacions Mèdiques (IMIM) have identified a new way of treating colorectal cancer. In the study published in the journal Science Signaling, the team led by LLuís Espinosa, investigator of IMIM's research group into stem cells and cancer, have shown that inhibition of endosomal activity is a potential therapeutic strategy for the treatment of cancers with the BRAF mutated gene.

BUSM researchers discover genes involved in formation of lung tumors

The lung transcription factor Nkx2-1 is an important gene regulating lung formation and normal respiratory functions after birth. Alterations in the expression of this transcription factor can lead to diseases such as lung interstitial disease, post-natal respiratory distress and lung cancer.

Damon Runyon Cancer Research Foundation names 15 new Damon Runyon Fellows

The Damon Runyon Cancer Research Foundation, a non-profit organization focused on supporting innovative early career researchers, named 15 new Damon Runyon Fellows at its fall Fellowship Award Committee review. The recipients of this prestigious, four-year award are outstanding postdoctoral scientists conducting basic and translational cancer research in the laboratories of leading senior investigators across the country.

UNC researchers discover how two genes interact to trigger worst form of ovarian cancer

In the battle against ovarian cancer, UNC School of Medicine researchers have created the first mouse model of the worst form of the disease and found a potential route to better treatments and much-needed diagnostic screens.

Progenitor cells responsible for generation and maintenance of Merkel cells

Researchers have identified a population of "progenitor" cells in the skin that are solely responsible for the generation and maintenance of touch-sensing Merkel cells. The study appears in The Journal of Cell Biology.

PKC enzymes categorized as cancer promoters are actually tumor suppressors

Upending decades-old dogma, a team of scientists at the University of California, San Diego School of Medicine say enzymes long categorized as promoting cancer are, in fact, tumor suppressors and that current clinical efforts to develop inhibitor-based drugs should instead focus on restoring the enzymes' activities.

Study: Mutated ATRX gene may serve as much-needed biomarker for rare neuroendocrine tumors

A somatic mutation in the ATRX gene has recently been shown as a potential molecular marker for aggressive brain tumors, such as gliomas, neuroblastomas and pancreatic neuroendocrine tumors. Now, for the first time, researchers at Penn's Abramson Cancer Center have found that the same mutated gene may serve as a much-needed biomarker for the pheochromocytomas and paragangliomas (PCC/PGL) that become malignant.

Atmospheric oxygen may play role in lung carcinogenesis, new study suggests

The ancient physician/alchemist, Paracelsus, said: "The dose makes the poison." According to a new study published in PeerJ, even oxygen may fall prey to the above adage. While essential to human life, aspects of oxygen metabolism may promote cancer. Capitalizing on the inverse relationship of oxygen concentration with elevation, researchers found lower rates of lung cancer at higher elevations, a trend that did not extend to non-respiratory cancers, suggesting that carcinogen exposure occurs via inhalation.
