The researchers used electrospinning to produce the patch—a method where high voltage is applied to a polymer solution to produce synthetic nanofibers. The fibers are then used to make a fiber mat that may be attached to the skin like a plaster.

The researchers are still working on the patch. More research, product development and clinical trials are needed before the method is ready for use.

According to Andrea Heinz, though, it has great potential that extends beyond psoriasis treatment, “A patch containing active ingredients may be an alternative to creams and ointments in the treatment of other inflammatory skin diseases, for instance atopic eczema. It may also be useful in connection with wound healing.”

DNA repair and DNA damage signaling pathways are critical for the maintenance of genomic stability.

In this review, Hopkins et al. review the major classes of DNA repair and damage signaling defects in cancer, the genomic instability that they give rise to, and therapeutic strategies to exploit the resulting vulnerabilities. They also discuss the impacts of DNA repair defects on both targeted therapy and immunotherapy, and highlight emerging principles for targeting DNA repair defects in cancer therapy.

A research team from the University of Basel has succeeded in synthesizing simple, environmentally sensitive cells complete with artificial organelles. For the first time, the researchers have also been able to emulate natural cell-cell communication using these protocells—based on the model of photoreceptors in the eye. This opens up new possibilities for basic research and applications in medicine.

For example, enhancers (DNA segments that promote gene expression) and gene promoters (regions that initiate transcription) can interact more readily in open, accessible regions of chromatin.

On the other hand, DNA in tightly packed chromatin regions remains less active. Through analyzing these contact points, researchers have developed models to map chromatin configurations across various species, such as humans, mice, birds, and more recently, turtles.

In a recent paper published in the journal Genome Research, Valenzuela’s team described the chromatin arrangement in the genomes of two turtle species, the spiny softshell and northern giant musk turtles, uncovering a structure previously unobserved in other organisms.
