A single species of gut bacteria can reverse autism-related social behavior in mice

The absence of one specific species of gut bacteria causes social deficits in mice. Researchers at Baylor College of Medicine report June 16 in Cell that by adding this bacterial species back to the guts of affected mice, the researchers were able to reverse some of the mice’s behavioral deficits, which are reminiscent of symptoms … Continue reading

Twinning linked to genes tied to reproductive fitness traits

Bearing fraternal twins, or dizygotic (DZ) twinning, runs in families, is potentially influenced by more than one gene and linked to a maternal factor. In a study published in the American Journal of Human Genetics, an international team reports the finding of two genes that are associated with increased odds for women bearing fraternal twins. … Continue reading

The mTOR pathway: a new avenue for breast cancer cells to promote tumor growth

Cancer cells respond in various ways to the body’s attempts to eliminate them. One strategy is to recruit immune cells in the body, such as the myeloid-derived suppressor cells (MDSCs), which are involved in the suppression of the body’s response against tumors. “There are alternative paths a tumor may take without the MDSCs, but those … Continue reading

Image of the Month: C60 fullerene ‘bucky balls’ help deliver pharmacologic agents to cancer cells

Drs. Steven Curley and Stuart Corr in the Electromagnetic Field and Nanomaterials Research Laboratory at Baylor are linking nanoparticles, such as the C60 fullerene bucky ball shown in this image (light purple), to pharmacologic agents (green).  When exposed to low levels of radio frequency fields, drug-loaded bucky balls enhance the delivery and retention of chemotherapeutics … Continue reading
