Infection with Helicobacter pylori is a risk factor for the development of gastric cancer. H. pylori initiates a chronic inflammatory response that can lead to the production of excessive radical oxygen species (ROS), which in turn can activate oncogenic signaling pathways leading to gastric cancer development. SUMOylation is a post-translational modification mechanism in cells in response to reactions to stress. A team at The First Affiliated Hospital of Nanchang University hence set out to study the role of SUMO-activating enzyme subunit 1 (SAE1) in gastric cancer, since it is a SUMO-activating effector protein.

Combating Antibiotic-Resistant Bacteria Biopharmaceutical Accelerator (CARB-X), led by Boston University, is awarding $1.2 million to the Andrew G. Myers Research Group at Harvard University to develop a series of enhanced oral antibiotics that directly target a range of antibiotic-resistant bacteria which cause serious lower respiratory tract and skin and soft tissue infections.

Trawsfynydd Therapeutics Inc. has received approval to initiate a first-in-man phase I trial of the novel best-in-class COVID-19 treatment, TRX-01, an inhibitor targeting the SARS-CoV-2 viral main protease (3CL, Mpro).

Aatec Medical GmbH has announced the start of its collaboration with the German Federal Agency for Disruptive Innovations (SPRIND), which will help advance the preclinical development of ATL-105.

A common molecular pathway associated with lung fibrosis may also hold the key to pulmonary vascular repair. A group of scientists at the University of Pennsylvania (Penn) found that when a viral infection damaged these vessels, the injury could be restored by activating the transforming growth factor-β receptor 2 (TGF-βR2) in endothelial cells, which led to cell proliferation.

COVID-19 severity remains open to several questions. Researchers at the University of California Los Angeles (UCLA) have revealed how SARS-CoV-2 causes acute inflammation instead of the symptoms of a common cold. This effect could be initiated by the peptide fragments of the coronavirus released when the host eliminates the virus, which can form pro-inflammatory complexes that trigger an amplified immune response.

Bone morphogenetic protein 9 (BMP-9), also known as growth/differentiation factor 2, is a member of the transforming growth factor-β family of cytokines, which exerts its biological effects through binding to a complex formed by ALK1 and BMPR2.
