Novel approach to sort out good or bad mutations associated with lymphoma

As anyone familiar with the X-Men knows, mutants can be either very good or very bad - or somewhere in between. The same appears true within cancer cells, which may harbor hundreds of mutations that set them apart from other cells in the body; the scientific challenge has been to figure out which mutations are culprits and which are innocent bystanders.

Study finds new signaling pathway involved in development of chronic inflammation of brain cells

The number of Alzheimer's patients will continue to dramatically increase in the next several decades. Various teams of researchers worldwide are feverishly investigating precisely how the illness develops. A

Everolimus therapy might treat Myc-driven lymphoma

Drugs that are used in the clinic to treat some forms of breast and kidney cancer and that work by inhibiting the signaling molecule mTORC1 might have utility in treating some of the more than 15 percent of human cancers driven by alterations in the Myc gene, according to data from a preclinical study published in Cancer Discovery, a journal of the American Association for Cancer Research.

EZH2 protein enables advanced prostate cancers to spread without stimulation by male hormones

Scientists at Dana-Farber Cancer Institute have discovered a molecular switch that enables advanced prostate cancers to spread without stimulation by male hormones, which normally are needed to spur the cancer's growth. They say the finding could lead to a new treatment for prostate cancers that are no longer controlled by hormone-blocking drugs.

Surprising discovery about physical properties of cancer cells

A surprising discovery about the physical properties of cancer cells could help improve a new diagnostic approach - a liquid biopsy - that detects, measures, and evaluates cancer cells in blood.

microRNAs play an important role during embryonic development

Sanford-Burnham researchers discover that microRNAs play an important role in germ layer formation-the process that determines which cells become which organs during embryonic development

Selumetinib plus docetaxel shows KRAS-mutant NSCLC potential

The addition of selumetinib to docetaxel therapy may boost the survival of patients with KRAS-mutant non-small-cell lung cancer, suggest study findings published in The Lancet Oncology.

Gadd45g protein essential in initiating development of male sex organs

Scientists at the Institute of Molecular Biology (IMB) in Mainz have identified a protein essential for initiating the development of male sex organs. Loss of the gene Gadd45g results in complete sex reversal of male mice, making them appear female.

Nonfunctional MED12 gene linked to chemotherapy resistance

Research published in Cell shows that people with tumors that have a nonfunctional version of the mediator 12 gene are resistant to drugs used to treat lung and colon cancer such as gefitinib.

Researchers reveal molecular mechanisms that lead to basal cell carcinoma initiation

Advanced online publication in Nature Cell Biology: Researchers at the Université libre de Bruxelles, uncover the molecular mechanisms leading to basal cell carcinoma initiation.

TGF-betaR inhibitors may counter drug resistance in cancer patients with MED12 mutations

Cancer therapies often have short-lived benefits due to the emergence of genetic mutations that cause drug resistance. A key gene that determines resistance to a range of cancer drugs has been reported in a study published by Cell Press November 21st in the journal Cell.

Coronary arteries largely arise from cells of the endocardium

During embryonic development, the all-important coronary arteries arise from cells previously considered incapable of producing them, according to scientists at Albert Einstein College of Medicine of Yeshiva University.

Researchers discover new cause of hydrocephalus

Researchers at the University of Iowa have discovered a new cause of hydrocephalus, a devastating neurological disorder that affects between one and three of every 1,000 babies born. Working in mice, the researchers identified a cell signaling defect, which disrupts immature brain cells involved in normal brain development.

Scientists reveal timing mechanism in formation of vertebrae

As they develop, vertebrate embryos form vertebrae in a sequential, time-controlled way. Scientists have determined previously that this process of body segmentation is controlled by a kind of "clock," regulated by the oscillating activity of certain genes within embryonic cells. But questions remain about how precisely this timing system works.

Researchers discover how tamoxifen-resistant breast-cancer cells grow and proliferate

A study by researchers at the Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) has discovered how tamoxifen-resistant breast-cancer cells grow and proliferate.

Blocking RSK protein activity could improve treatment of skin cancers

Blocking the action of a particular protein in our skin could improve the treatment of skin cancers, according to a study published in Oncogene yesterday by Philippe Roux, a researcher at the University of Montreal's Institute for Research in Immunology and Cancer (IRIC).
