New class of synthetic molecules mimics antibodies
A Yale University lab has crafted the first synthetic molecules that have both the targeting and response functions of antibodies. The new molecules -- synthetic antibody mimics -- attach themselves simultaneously to disease cells and disease-fighting cells. The result is a highly targeted immune response, similar to the action of natural human antibodies.

'Master regulator' gene -- long tied to autism disorders -- stimulates other genes in early brain development
Chemical modifications to DNA's packaging -- known as epigenetic changes -- can activate or repress genes involved in autism spectrum disorders and early brain development, according to a new study to be published in the journal Nature on Dec. 18.

'Sugar-coated' microcapsule eliminates toxic punch of experimental anti-cancer drug
Johns Hopkins researchers have developed a sugar-based molecular microcapsule that eliminates the toxicity of an anticancer agent developed a decade ago at Johns Hopkins, called 3-bromopyruvate, or 3BrPA, in studies of mice with implants of human pancreatic cancer tissue. The encapsulated drug packed a potent anticancer punch, stopping the progression of tumors in the mice, but without the usual toxic effects.

Orphan receptor proteins deliver 2 knock-out punches to glioblastoma cells
Two related proteins exert a lethal double whammy effect against glioblastoma cells when activated with a small molecule. Scientists say when activated, one protein, called the short form, stops glioblastoma cells from replicating their DNA, and the other, called the long form, prevents cell division if the DNA has already been replicated.

A new strategy for developing drugs to fight cancer and other diseases
Promising treatments known as biologics are on the market and under development for many serious illnesses such as cancer, but some of them come with high risks, even lethal ones. Now scientists have produced a novel class of molecules that could be as effective but without the dangerous side effects. They report their work on these compounds, which they tested on prostate cancer cells, in ACS' Journal of the American Chemical Society.

Study shows how breast cancer cells break free to spread in the body
More than 90 percent of cancer-related deaths are caused by the spread of cancer cells from their primary tumor site to other areas of the body. A new study has identified how one important gene helps cancer cells break free from the primary tumor.

New technology directly reprograms skin fibroblasts for a new role
Scientists have discovered a way to repurpose fibroblasts into functional melanocytes, the body's pigment-producing cells. The technique has immediate and important implications for developing new cell-based treatments for skin diseases such as vitiligo, as well as new screening strategies for melanoma.

Effectiveness of drugs to prevent hepatitis among patients receiving chemotherapy
Among patients with lymphoma undergoing a certain type of chemotherapy, receiving the antiviral drug entecavir resulted in a lower incidence of hepatitis B virus (HBV)-related hepatitis and HBV reactivation, compared with the antiviral drug lamivudine, according to a study in the Dec. 17 issue of JAMA.

Microwave imaging of the breast
Although currently available diagnostic screening systems for breast are effective at detecting early signs of tumors, they are far from perfect, subjecting patients to ionizing radiation and sometimes inflicting discomfort on women who are undergoing screening because of the compression of the breast that is required to produce diagnostically useful images. New research suggests a better, cheaper, and safer way to look for the telltale signs of breast cancer may be with microwaves.

Single genetic abnormality accelerates, removes the brakes on Ewing sarcoma tumor growth
The genetic abnormality that drives the bone cancer Ewing sarcoma operates through two distinct processes -- both activating genes that stimulate tumor growth and suppressing those that should keep cancer from developing.

Vessel research offers new direction to study how cancer spreads
Researchers have understood very little about how blood and lymphatic vessels form in the mammalian gut -- until now. A new Cornell University study reports for the first time how arteries form to supply the looping embryonic gut with blood, and how these arteries guide development of the gut's lymphatic system.

Bacterial 'bunches' linked to some colorectal cancers
Researchers from Johns Hopkins have found that dense mats of interacting bacteria, called biofilms, were present in the majority of cancers and polyps, particularly those on the right side of the colon. The presence of these bacterial bunches, they say, may represent an increased risk for colon cancer and could form the basis of new diagnostic tests.

Research: Two drugs before surgery help women with triple-negative breast cancer
A breast cancer specialist and clinical researcher at Women & Infants Hospital of Rhode Island presented research yesterday at the 2014 San Antonio Breast Cancer Symposium showing that adding either the chemotherapy drug carboplatin or the blood vessel-targeting drug bevacizumab to the standard treatment of chemotherapy before surgery helped women who have the basal-like subtype of triple-negative breast cancer.

E-cigarettes may recruit lower risk teens to nicotine use
A new study finds that one-third of Hawaiian adolescents have tried e-cigarettes, half of whom have never used another tobacco product. This is markedly higher rate than in the continental US. This raises the possibility that e-cigarettes are recruiting lower risk adolescents, who otherwise would be less susceptible to tobacco product use.
