Tiny DNA Architects Pinpointed in Genome

February 22, 2013 9:53 am | News | Comments

If a genome is the blueprint for life, then the chief architects are tiny slices of genetic material that orchestrate how we are assembled and function, researchers report.

Resistant Starches Can Protect Against Cancer

February 20, 2013 11:35 am | News | Comments

A new study shows that resistant starch helps the body resist colorectal cancer through mechanisms including killing pre-cancerous cells and reducing inflammation that can otherwise promote cancer.

Codon Speeds Dictate Protein Performance

February 20, 2013 10:10 am | News | Comments

A team of researchers has shown that the concept of how the speed of creation affects performance also applies to how a protein they studied impacts circadian clock function.

Cepheid plans breast and prostate cancer test

February 19, 2013 4:57 pm | by The Associated Press | News | Comments

Diagnostics maker Cepheid said Tuesday it will work with Oregon Health & Science University to develop tests that predict the risk of recurrence of breast and prostate cancer. Cepheid said it will work with OHSU's Knight Cancer Institute. The tests will run on the Cepheid GeneXpert system....

February 15, 2013 6:31 pm | by The Associated Press | News | Comments

Shares of Pharmacyclics Inc. climbed to an all-time high Friday after the company said it expects to file for marketing approval of its cancer drug ibrutinib this year. If approved, it would be Pharmacyclics first drug for sale.

Personalized Cancer Drug Selection a Possibility

February 15, 2013 11:13 am | News | Comments

Scientists have developed a way to personalize chemotherapy drug selection for cancer patients by using cell lines created from their own tumors.

Gene Family Suppresses Cancer-Causing Herpes

February 14, 2013 9:49 am | News | Comments

Researchers have identified a family of human genes known as Tousled-like kinases (TLKs) that play a key role in the suppression and activation of Kaposi’s sarcoma-associated herpesvirus (KSHV) and Epstein-Barr virus (EBV).

Adapted Biosensor Naturally Detects Cocaine

February 13, 2013 4:25 pm | News | Comments

Researchers have adapted natural mechanisms in living organisms to detect specific molecules, such as cocaine, more accurately and quickly. Their work may greatly facilitate the rapid screening of many drugs, infectious diseases and cancers.

Emerging Cancer Drugs Can Spread Tumors

February 13, 2013 10:31 am | News | Comments

New evidence suggests that an otherwise promising class of cancer drugs may actually increase the risk of tumors spreading to bone, according to researchers.

Virus-Fighting Enzyme Implicated in Breast Cancer

February 11, 2013 4:40 pm | News | Comments

Researchers have found evidence that one of our own proteins is a major source of mutations evident in most breast cancers.

Blood Vessels Linked to Spread of Cancer Cells

February 11, 2013 4:29 pm | News | Comments

A lack of the protein endoglin in the blood vessels of tumour-bearing mice enables the spread of daughter tumours, according to researchers. Given that the tumour vasculature constitutes an important barrier to the spread of cancer cells, the team suggests that drugs should be developed to strengthen the blood vessels' protective function.

Protein Paves the Way for Correct Stem Cell Differentiation

February 8, 2013 10:20 am | News | Comments

A single embryonic stem cell can develop into more than 200 specialized cell types that make up our body. This maturation process is called differentiation and is tightly regulated through strict control of gene activity. If the regulation is lost, specialized cells cannot develop correctly during development. In adulthood, the specialized cells may forget their identity and develop into cancer cells.

Tiny Capsule Effectively Kills Cancer Cells

February 7, 2013 11:15 am | News | Comments

Devising a method for more precise and less invasive treatment of cancer tumors, a team led by researchers from the UCLA Henry Samueli School of Engineering and Applied Science has developed a degradable nanoscale shell to carry proteins to cancer cells and stunt the growth of tumors without damaging healthy cells.

Changes to DNA On-Off Switches Affect Cells' Ability to Repair Breaks, Respond to Chemotherapy

February 5, 2013 10:57 am | News | Comments

Double-strand breaks in DNA happen every time a cell divides and replicates. Depending on the type of cell, that can be pretty often. Many proteins are involved in everyday DNA repair, but if they are mutated, the repair system breaks down and cancer can occur. Cells have two complicated ways to repair these breaks, which can affect the stability of the entire genome.

Researchers Develop Automated Breast Density Test Linked To Cancer Risk

February 4, 2013 11:06 am | News | Comments

Researchers have developed a novel computer algorithm to quantify a major risk factor for breast cancer based on analysis of a screening mammogram. Increased levels of mammographic breast density have been shown in multiple studies to be correlated with elevated risk of breast cancer, but the approach to quantifying it has been limited to the laboratory setting. This new discovery opens the door for translation to the clinic.
