Specific way of spelling out genetic code likely allows viruses to evade our cellular defenses

For millions of years, humans and viruses have engaged in a constant tug of war: as our cells evolve new ways to defend us from our viral enemies, these pathogens in turn acquire new traits to sidestep those defenses.

Common genetic fusion event could help identify patients with low-risk prostate cancer

Establishing the way in which a genetic alteration called a TMPRSS2-ERG gene fusion forms in a prostate cancer, rather than the presence of the gene fusion itself, could help identify patients with prostate cancer with a low risk of spreading, which might determine the best course of treatment for the patient.

KU Leuven researchers unravel how cell division timer works

Human cells use a timer to divide: each cell gets at least 30 minutes to divide its genetic material between the nuclei of two daughter cells.

LoaScope could be valuable approach in the fight against river blindness

River blindness, or onchocerciasis, is a disease caused by a parasitic worm found primarily in Africa. The worm (Onchocerca volvulus) is transmitted to humans as immature larvae through bites of infected black flies.

Study finds role of body clock in wound healing

A new study conducted at the Medical Research Council (MRC) Laboratory of Molecular Biology, UK, has found how wound healing is regulated by the body clock in such a way that injuries that occured at daytime heal nearly 60% faster than that at night.

Complete new skin from transgenic stem cells for boy with rare genetic disease

Hassan, a then seven-year-old boy from Germany, in 2015, presented to the doctors with a rare skin disease called junctional epidermolysis bullosa or JEB. This condition leaves the skin thin and papery and easily breakable. It has been compared to “butterfly wings” because of their fragile nature.

Scientists uncover previously unknown mechanism to combat influenza A virus

Just as flu season swings into full gear, researchers from the University of Colorado Boulder and University of Texas at Austin have uncovered a previously unknown mechanism by which the human immune system tries to battle the influenza A virus.

Researchers use gold nanoshells to effectively release cancer drugs inside tumors

Researchers investigating ways to deliver high doses of cancer-killing drugs inside tumors have shown they can use a laser and light-activated gold nanoparticles to remotely trigger the release of approved cancer drugs inside cancer cells in laboratory cultures.

Exposure to BPA during pregnancy may lead to long-lasting health problems in offspring

A chemical called bisphenol A -- BPA -- used in plastic packaging and in the linings of food and beverage cans, may be passed from a mother to her offspring during pregnancy and cause changes in the gut bacteria of the offspring, according to an international team of researchers.

Adipocytes may reduce effectiveness of chemotherapeutic drug

Adipocytes, or fat cells, can absorb and metabolize the chemotherapeutic agent daunorubicin, reducing the effectiveness of the drug and potentially contributing to poorer treatment outcomes.
