UC San Diego's Scott Lippman to launch and lead NCI-sponsored PreCancer Genome Atlas

Scott Lippman, MD, will launch and lead the PreCancer Genome Atlas, a National Cancer Institute (NCI)-sponsored effort to map in time and space all of the molecular, cellular and structural characteristics of premalignant lesions and how they evolve into invasive cancers.

Glycosylation and disulfide bonding profile of SARS-CoV-2 spike glycoprotein

Researchers found that virus-like particles produced by co-expression of SARS-CoV-2 S, membrane, envelope, and nucleocapsid proteins contain S glycoproteins, which are modified by complex carbohydrates.

Extended host range for SARS-CoV-2 variants of concern

Researchers used viral pseudotyping to examine whether variants of concern had different host ACE2 receptor usage patterns.

Study suggests making COVID vaccines based on Mu variant

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) Mu variant (B.1.621, B.1.621.1) has been tagged as a Variant Being Monitored (VBM), and as of August 30, 2021, it had been detected in 39 countries.

Identifying the spread of novel B.1.1.523 SARS-CoV-2

In their recent study, researchers from Lithuania have reported the emergence of a novel severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) variant lineage B.1.1.523 containing a set of mutations associated with immune escape, including deletion 156_158del, substitution E484K and S494P in Spike (S) protein.
