Berkeley Lab Scientists Find That Normal Breast Cells Help Kill Cancer Cells

It is well known that the human body has a highly developed immune system to detect and destroy invading pathogens and tumor cells. Now, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) have shown that the body has a second line of defense against cancer – healthy cells. A new study shows that normal mammary epithelial cells, as they are developing, secrete interleukin 25, a protein known for its role in the immune system’s response to inflammation, for the express purpose of killing nearby breast cancer cells.

“We found that normal breast cells provide an innate defense mechanism against cancer by producing interleukin 25 (IL25) to actively and specifically kill breast cancer cells,” says breast cancer authority Mina Bissell, of Berkeley Lab’s Life Sciences Division, who led this research. “This suggests that IL25 receptor signaling may provide a new therapeutic target for the treatment of breast cancer.” (more…)

Study Finds Public Relatively Unconcerned About Nanotechnology Risks

A new study finds that the general public thinks getting a suntan poses a greater public health risk than nanotechnology or other nanoparticle applications. The study, from North Carolina State University, compared survey respondents’ perceived risk of nanoparticles with 23 other public-health risks.

The study is the first to compare the public’s perception of the risks associated with nanoparticles to other environmental and health safety risks. Researchers found that nanoparticles are perceived as being a relatively low risk. (more…)

Sub-Saharan Africa is struggling with twin epidemics — HIV and heroin addiction — and Tanzania, in eastern Africa, is one of the hardest-hit regions.

But now, with funding from the U.S. government and organizational expertise from Yale, an effort is underway there to get heroin addiction and the viruses spawned by the sharing of contaminated needles — HIV, Hepatitis B and C — under control. (more…)

*California’s aging LGB population is set to double in next 20 years*

Members of California’s aging lesbian, gay and bisexual population are more likely to suffer from certain chronic conditions, even as they wrestle with the challenges of living alone in far higher numbers than the heterosexual population, according to new policy brief from the UCLA Center for Health Policy Research.

Half of all gay and bisexual adult men in California between the ages of 50 and 70 are living alone, compared with 13.4 percent of heterosexual men in the same age group. And although older California lesbians and bisexual women are more likely to live with a partner or a family member than their male counterparts, more than one in four live alone, compared with one in five heterosexual women.
