Authors: By Suchandrima BhowmikAug 15 2021Reviewed by Benedette Cuffari, M.Sc. The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), which is the virus that causes coronavirus disease 2019 (COVID-19), is associated with high mortality and hospitalization rates. However, many patients who are infected with SARS-CoV-2 remain asymptomatic or develop mild symptoms. In a recent study published on the […]

Authors: Igor Moshynskyy 1, Sathiyanarayanan Viswanathan, Natalia Vasilenko, Vladislav Lobanov, Martin Petric, Lorne A Babiuk, Alexander N Zakhartchouk Abstract Open reading frame 9b (ORF 9b) encodes a 98 amino acid group-specific protein of severe acute respiratory syndrome (SARS) coronavirus (CoV). It has no homology with known proteins and its function in SARS CoV replication has not been determined. The N-terminal part of […]

RaduAricescu13ReneAssenberg2Robin T.Aplin2Robert J.C.Gilbert13Jonathan M.Grimes123David I.Stuart123 Summary To achieve the greatest output from their limited genomes, viruses frequently make use of alternative open reading frames, in which translation is initiated from a start codon within an existing gene and, being out of frame, gives rise to a distinct protein product. These alternative protein products are, as yet, […]

Authors: Setu M. Vora,1,2Judy Lieberman,2,3 and Hao Wu1,2 Abstract The COVID-19 pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), results in life-threatening disease in a minority of patients, especially elderly people and those with co-morbidities such as obesity and diabetes. Severe disease is characterized by dysregulated cytokine release, pneumonia and acute lung injury, which can […]

COVID-19 Host Genetics Initiative, Nature (2021) Abstract The genetic makeup of an individual contributes to susceptibility and response to viral infection. While environmental, clinical and social factors play a role in exposure to SARS-CoV-2 and COVID-19 disease severity1,2, host genetics may also be important. Identifying host-specific genetic factors may reveal biological mechanisms of therapeutic relevance and […]
