Scientists discover more on gene expression

Scientists discover what happens in gene transcription University of Michigan scientists discovers that it only 2 percent of the human genome code for cellular functions of proteins while 98 percent of the noncoding DNA accounts for gene expression.

Correct antibiotic dosing could preserve lung microbial diversity in cystic fibrosis

Children and young adults with cystic fibrosis (CF) whose lung infections were treated with suboptimal doses of antibiotics had fewer changes in lung microbial diversity during the IV treatment, and their microbial diversity levels were higher 30 days later, a multi-institutional study that includes Children's researchers shows.

How breast tissue stiffening promotes breast cancer development

A study provides new insight into how the stiffening of breast tissue plays a role in breast cancer development. By examining how mammary cells respond in a stiffness-changing hydrogel, bioengineers at the University of California San Diego discovered that several pathways work together to promote the transformation of breast cells into cancer cells. The work could inspire new approaches to treating patients and inhibiting tumor growth.

BFU physicists developed a new method to identify antibiotics-resistant bacteria

A team of physicists from Immanuel Kant Baltic State University suggested a method to quickly identify single antibiotic-resistant bacteria cells that are the agents of tuberculosis. The new method helps find the bacteria and evaluate their resistance to antibiotics without damaging the biological material. The results of the first trial of the method were published in Data in Brief.

Gene therapy: utilizing nanotechnology in fighting against Chlamydia

Scientists in Canada have developed a new method for preventing and treating chlamydia. Chlamydia, caused by Chlamydia trachomatis, is a common sexually transmitted disease that can infect women with cervicitis and in both men and women with urethritis and proctitis. The team of researchers from the University of Waterloo treats chlamydia through gene therapy using nanotechnology.
