A technique used by animators helps scientists model how cancer cells enter the bloodstream.
Researchers have identified PHF20, a novel transcriptional factor, and clarified its role in maintaining the stability and transcription of p53, a gene that allows for both normal cell growth and tumor suppression. PHF20, the researchers found, plays a previously unknown and unique role in regulating p53.
Women with Alzheimer’s show worse mental deterioration than men with the disease, even when at the same stage of the condition, according to new research.
Scientists have discovered that an extract from a common plant in Pakistan may help treat breast cancer.
Molecular biologists have gained new insights into the function of so-called molecular chaperones in protein synthesis. Scientists were able to demonstrate how a molecular chaperone in bacterial cells can influence the formation of the three-dimensional structure of new proteins.
Researchers from the Laboratory of astrocyte biology and CNS regeneration headed by Prof. Milos Pekny just published a research article in a prestigious journal Stem Cells on the molecular mechanism that controls generation of new neurons in the brain.
Researchers describe new molecular interactions behind the inhibition of TGF beta-signaling.
The hawkmoth, a natural petunia pollinator, spends less time on Petunia lines that offer less nectar as a reward.
Squishy models are anything but child’s play as they help researchers understand the building-block nature of proteins.
By affixing nanoscale gold spheres onto a microscopic bead of glass, researchers have created a super-sensor that can detect even single samples of the smallest known viruses. The sensor uses a peculiar behavior of light known as "whispering gallery mode," named after the famous circular gallery in St. Paul's Cathedral in London, where a whisper near the wall can be heard around the gallery.
When blown by chaotic winds in an urban environment, pollutants tend to accumulate in specific neighborhoods.
Stem cells isolated from fat are being considered as an option for treating tissue damage and diseases because of their accessibility and lack of rejection. New research shows that this is not as straightforward as previously believed, and that fat-derived stem cells secrete VEGF and other factors, which can inhibit cartilage regeneration. However pre-treating the cells with antibodies against VEGF and growing them in nutrients specifically designed to promote chondrocytes can neutralize these effects.
