Scientists discover cytochrome P450 family member CYP39A1 can block hepatocarcinogenesis

Credit: CC0 Public Domain Hepatocellular carcinoma (HCC) is two to five times more common in men than in women. An in-depth analysis of the mechanisms underlying the gender heterogeneity of HCC may contribute to the identification of key HCC suppression mechanisms physiologically present in women, thus benefiting the HCC cohort. Against this backdrop, Prof. Ji …

Scientists find potential diagnostic and therapeutic target for lung cancer

Scientists find potential diagnostic and therapeutic target for lung cancer

Proposed model for the LCDR/hnRNP K/LAPTM5 axis promoting the pathogenesis of lung cancer. Credit: Gao Shan Chinese scientists recently reported the key role in tumor survival played by a histone-acetylation-regulated long noncoding RNA called lysosome cell death regulator (LCDR), providing a potential diagnostic and therapeutic target for lung cancer. Led by Prof. Gao Shan from …

Expect more worrisome variants after omicron, scientists say

Expect more worrisome variants after omicron, scientists say

People wait in line at a COVID-19 testing site in Times Square, New York, Monday, Dec. 13, 2021. Scientists are warning that omicron’s lightning-fast spread across the globe practically ensures it won’t be the last worrisome coronavirus variant. And there’s no guarantee the next ones will cause milder illness or that vaccines will work against …

Scientists employ AI to predict which viruses could infect humans in future

Daniel Becker, an assistant professor of biology in the University of Oklahoma’s Dodge Family College of Arts and Sciences, has been leading a proactive modeling study over the last year and a half to identify bat species that are likely to carry betacoronaviruses, including but not limited to SARS-like viruses. The study “Optimizing predictive models …

How scientists know which variants are circulating in the US

How scientists know which variants are circulating in the US

The omicron variant quickly took over the global coronavirus landscape after it was first reported in South Africa in late November, 2021. The U.S. became the 24th country to report a case of omicron infection when health officials announced on Dec. 1, 2021, that the new strain had been identified in a patient in California. …

What can 35-year-old stool samples tell scientists about HIV/AIDS?

HIV-1 Virus. Credit: J Roberto Trujillo/Wikipedia Men who contracted HIV in the early days of the HIV/AIDS pandemic harbored a greater relative abundance of pro-inflammatory vs. anti-inflammatory gut microbes before they became HIV-positive compared to their counterparts who remained HIV-negative, according to new research published today in the journal Microbiome. In addition, the men who …

WHO, US scientists say Omicron no worse than other virus variants

WHO, US scientists say Omicron no worse than other virus variants

The Omicron variant has forced dozens of nations to re-impose border restrictions and raised the possibility of a return to economically punishing lockdowns. The Omicron variant appears to be no worse than other coronavirus strains, top scientists from the WHO and the United States told AFP, while cautioning that more research is needed to judge …

Scientists identify molecular features of antibody responses to SARS-CoV-2 spike

Scientists from the US have recently characterized a panel of anti-severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) antibodies to identify molecular features of public antibody responses to SARS-CoV-2 spike protein. Study: A large-scale systematic survey of SARS-CoV-2 antibodies reveals recurring molecular features. Image Credits: Mongkolchon Akesin/Shutterstock The study is currently available on the nioRxiv* preprint …
