Surviving bodily defenses: human rotavirus manipulates immune response to maintain infection

The gut of a child infected with rotavirus is like a battleground. On one side, the virus invades the epithelial cells that form the lining of the small intestine. The virus replicates driving havoc in the intestinal environment, which causes severe diarrhea, vomiting, fever and abdominal pain. Dehydration usually follows and, unless the child is … Continue reading

A pill to prevent Alzheimer’s disease might someday be a reality

Taking a pill that prevents the accumulation of toxic molecules in the brain might someday help prevent or delay Alzheimer’s disease, according to scientists at Baylor College of Medicine, Texas Children’s Hospital and Johns Hopkins University School of Medicine. The scientists took a three-pronged approach to help subdue early events that occur in the brain long before … Continue reading

Improving the view on the genetic causes of retinitis pigmentosa

Progressive development of night blindness and tunnel vision, sometimes from the early age of 2, are trademarks of retinitis pigmentosa. Being the most common inherited disorder of the retina, retinitis pigmentosa affects nearly 1 in 4,000 people. More than 1 million are visually impaired around the world due to this untreatable disease. A number of … Continue reading

“Freeze-frame” synthetic proteins capture DNA events leading to cancer

Cancer scientists have focused on identifying signature genetic changes present in cancerous cells and understanding how these changes lead to cancer. Although this approach has delivered important advances, at Baylor College of Medicine Dr. Susan Rosenberg and colleagues wanted to get closer look at how these changes happen. “In my lab we study how the … Continue reading

How breast cancer can become resistant to hormone therapy

Despite the overall success of hormone therapy, breast cancer tumors in patients with metastatic disease often fail to respond. One new mechanism that can explain resistance to hormone therapy in breast cancer involves two significant changes in the cells – overexpression of the FOXA1 gene and increased production of IL-8. A cluster of breast cancer … Continue reading

Image of the Month: Neuron-muscle synapses in the fruit fly

Certain human gene variants of ATAD3A can cause rare neurological syndromes characterized by global developmental delay, low muscular tone and visual, neurological and heart problems. The association between gene variants of ATAD3A and the neurological conditons was established using a combination of patients’ whole-exome sequencing studies led by Dr. Tamar Harel and Dr. James R. Lupski, … Continue reading
