Researchers discover how c-MYC facilitates tumor growth

Cancer cells are essentially immortal. The acquisition of an unlimited capacity to divide - the process of immortalization - is a central event in the genesis of tumors. Normally, cells are subject to stringent mechanisms which control their proliferation. Together these ensure that pre-malignant cells are induced to enter a senescent, non-dividing state or to undergo apoptosis, i.e. commit suicide.

Newgen acquires novel oncology development programs from Kanion

NewGen Therapeutics, Inc. today announced the acquisition of three novel oncology development programs from Kanion USA, Inc. and Kanion Pharmaceutical Co., Ltd..

Chemical disruption to key interaction shown to limit metastasis in test mice

Finding ways to counteract or disrupt the invasive nature of cancer cells, called "metastasis," has been a long-term goal of cancer researchers. Now, researchers at Moffitt Cancer Center in Tampa, Fla., have identified an interactive pathway that regulates metastases in some cancers that may be vulnerable to chemical targeting in order to prevent cancer cell proliferation and tumor growth.

Scientists identify importance of novel protein-regulating mechanism

For years, science has generally considered the phosphorylation of proteins -- the insertion of a phosphorous group into a protein that turns it on or off -- as perhaps the factor regulating a range of cellular processes from cell metabolism to programmed cell death. Now, scientists from the Florida campus of The Scripps Research Institute have identified the importance of a novel protein-regulating mechanism -- called sulfenylation -- that is similar to phosphorylation and may, in fact, open up opportunities to develop new types of drugs for diseases such as cancer.

Researchers uncover binding pocket of 'functional significance' in Ras oncoprotein

A drug discovery team at Genentech, Inc., has uncovered a chink in the molecular armor of Ras, the most commonly occurring oncogene, which is a gene that when mutated has the potential of causing cancer in humans.

Study reveals PEA-15 protein can enhance cancer cell proliferation

A new study from the University of Hawaii Cancer Center reveals that PEA-15, a protein previously shown to slow ovarian tumor growth and metastasis, can alternatively enhance tumor formation in kidney cells carrying a mutation in a cancer-promoting gene called H-Ras.

Study demonstrates how DISC1 variants affect brain development

Significant progress has been made in understanding the genetic risk factors underlying psychiatric disease. Recent studies have identified common genetic mutations conferring modest risk and rare variants comprising significant risk. One example of a rare cause of psychiatric disorders is the Disrupted in Schizophrenia-1 (DISC1) gene, first identified in a large Scottish pedigree displaying schizophrenia, bipolar disorder and depression.

Regulated gene transcription more complex than previously thought

Cells develop and thrive by turning genes on and off as needed in a precise pattern, a process known as regulated gene transcription. In a paper published in the Nov. 9 issue of the Journal of Neuroscience, researchers at the University of California, San Diego School of Medicine say this process is even more complex than previously thought, with regulated genes actually relocated to other, more conducive places in the cell nucleus.

PKM2 enzyme has important non-metabolic functions in cancer formation

The embryonic enzyme pyruvate kinase M2 (PKM2) has a well-established role in metabolism and is highly expressed in human cancers. Now, a team led by researchers at the University of Texas MD Anderson Cancer Center reports in advance online publication of the journal Nature that PKM2 has important non-metabolic functions in cancer formation.
