Activating mutations in the CTNNB1 gene encoding β-catenin are among the most frequently observed oncogenic alterations in hepatocellular carcinoma (HCC). Profound alterations in lipid metabolism, including increases in fatty acid oxidation and transformation of the phospholipidome, occur in HCC with CTNNB1 mutations, but it is unclear what mechanisms give rise to these changes. We employed untargeted lipidomics and targeted isotope tracing to measure phospholipid synthesis activity in an inducible human liver cell line expressing mutant β-catenin, as well as in transgenic zebrafish with activated β-catenin-driven HCC.

Article Synopsis
  • * Researchers measured CO2 levels and air changes per hour (ACH) in 100 classrooms over 20 months, finding a significant link between high CO2 levels (≥1,000 ppm) and increased SARS-CoV-2 cases, although ACH alone didn't show a significant correlation.
  • * The results indicated that classrooms with MERV-13 filters had lower SARS-CoV-2 positivity rates, prompting ongoing improvements in the school’s ventilation systems to better safeguard student health.

Article Synopsis
  • Mutations in the β-catenin gene are common in hepatocellular carcinoma (HCC) and lead to significant changes in lipid metabolism, including altered fatty acid oxidation and phospholipid composition.
  • Research utilized lipidomics and isotope tracing in human liver cells and transgenic zebrafish to measure phospholipid production and found notable shifts in lipid classes, including reductions in phosphatidylcholine.
  • These findings highlight the impact of β-catenin signaling on lipid metabolism in HCC, suggesting potential lipid metabolic targets for future therapeutic strategies.

Background: This study examined the correlation of classroom ventilation (air exchanges per hour (ACH)) and exposure to CO ≥1,000 ppm with the incidence of SARS-CoV-2 over a 20-month period in a specialized school for students with intellectual and developmental disabilities (IDD). These students were at a higher risk of respiratory infection from SARS-CoV-2 due to challenges in tolerating mitigation measures (e.g.

Pertussis, commonly referred to as whooping cough, is one of the top 10 causes of death in children globally despite vaccine availability. Adhering to vaccination guidelines for both the primary childhood series as well as adolescent and adult boosters is crucial in preventing the spread of disease. However, due to vaccine failure, outbreaks occur every 3 to 5 years.
