Scientists Identify Gene Region that Fuels Asthma Inflammation

Pollen and house dust mites are two common allergens that cause respiratory distress in asthma patients. But type-2 helper T (Th2) cells and group-2 innate lymphoid cells (ILC2s) release a class of proteins known as type-2 cytokines in response to a variety of asthma triggers. GATA-binding protein 3 (GATA3) is essential for the maturation of Th2 and ILC2.

New Insights Into PARP1 Biology Could Open Avenues to Improve Cancer Treatments

A new study led by University of Pittsburgh and UPMC Hillman Cancer Center researchers shows that an enzyme called PARP1 is involved in repair of telomeres, the lengths of DNA that protect the tips of chromosomes, and that impairing this process can lead to telomere shortening and genomic instability that can cause cancer.
