Finicky Fat

30.08.2010
Ever wonder why men and women gain weight in different areas of the body? Researchers are coming close to understanding the vital sex differences in men and women concerning fat storage. In fact, research indicates that fat is genetically different in men and women.

A groundbreaking medical study from members of the SWHR-Isis Fund Network on Sex Differences and Metabolism sponsored by the Society for Women’s Health Research (SWHR), the nation’s leading advocate for the study of sex differences, uncovers new truths about fat deposition in male and female mice.

"Given the difference in gene expression profiles, a female fat tissue won't behave anything like a male fat tissue and vice versa," said Deborah Clegg, Ph.D., assistant professor of internal medicine at UT Southwestern Medical Center. "The notion that fat cells between males and females are alike is inconsistent with our findings."

Mice store their fat similar to humans in a sexually dimorphic pattern. Just like human males, male mice store their fat in the belly and midsection area while females store fat in their hips, thighs and buttocks. Fat around your central organs (also known as central adiposity) is the type that is most dangerous for subsequent development of chronic diseases.

Dr. Clegg, the senior author of the study appearing in the International Journal of Obesity, was surprised by the findings. “We found that out of about 40,000 mouse genes, only 138 are commonly found in both male and female fat cells,” said Dr. Clegg. “This was completely unexpected. We expected the exact opposite - that 138 would be different and the rest would be the same between the sexes.”

This news is especially helpful in determining the underlying causes of obesity-related diseases. Since men are more likely to carry extra weight around their bellies, they are at higher risk for numerous obesity-related diseases including diabetes and heart disease. Women, on the other hand, are usually protected from these disorders until menopause, when their ovarian hormone levels drop and fat storage tends to shift from their buttocks to their waists.

“The research being performed by Dr. Clegg and colleagues underscores the importance of understanding the differences in fat deposition in men and women,” said Viviana Simon, Ph.D., SWHR vice president of scientific affairs. “The ability to manipulate how and where in the body fat is deposited holds the promise of helping researchers develop strategies to prevent or delay the development of chronic conditions such as diabetes and cardiovascular disease.”

The Society for Women’s Health Research (SWHR), a national non-profit organization based in Washington D.C., is widely recognized as the thought leader in women’s health research, particularly how sex differences impact health. SWHR’s mission is to improve the health of all women through advocacy, education and research. Visit SWHR’s website at swhr.org for more information.

Moving into its fourth decade, AchemAsia is setting out for new horizons: The International Expo and Innovation Forum for Sustainable Chemical Production will take place from 21-23 May 2019 in Shanghai, China. With an updated event profile, the eleventh edition focusses on topics that are especially relevant for the Chinese process industry, putting a strong emphasis on sustainability and innovation.

Founded in 1989 as a spin-off of ACHEMA to cater to the needs of China’s then developing industry, AchemAsia has since grown into a platform where the latest...

Im Focus: First real-time test of Li-Fi utilization for the industrial Internet of Things

The BMBF-funded OWICELLS project was successfully completed with a final presentation at the BMW plant in Munich. The presentation demonstrated a Li-Fi communication with a mobile robot, while the robot carried out usual production processes (welding, moving and testing parts) in a 5x5m² production cell. The robust, optical wireless transmission is based on spatial diversity; in other words, data is sent and received simultaneously by several LEDs and several photodiodes. The system can transmit data at more than 100 Mbit/s and five milliseconds latency.

Modern production technologies in the automobile industry must become more flexible in order to fulfil individual customer requirements.

An international team of scientists has discovered a new way to transfer image information through multimodal fibers with almost no distortion - even if the fiber is bent. The results of the study, to which scientist from the Leibniz-Institute of Photonic Technology Jena (Leibniz IPHT) contributed, were published on 6thJune in the highly-cited journal Physical Review Letters.

Endoscopes allow doctors to see into a patient’s body like through a keyhole. Typically, the images are transmitted via a bundle of several hundreds of optical...
