Different Gut Microbiota for Patients with Hepatocellular Carcinoma

By Natalie Lo ‘21 Hepatocellular Carcinoma (HCC) is a common form of liver cancer and is possibly related to an infection of hepatitis B virus (HBV) since it can result in cancer formation through activation of oncogenic proteins, inflammation, and cirrhosis. Through a symbiotic relationship, microorganisms in the gut interact with organs in humans, such as the liver, and play an important role in nutrition … Continue reading Different Gut Microbiota for Patients with Hepatocellular Carcinoma

The Effects of the Gut on Fruit Flies’ Lifespans

By Caleb Sooknanan ‘20 Aging and chronic diseases are often associated with effects such as metabolic and oxidative stresses, inflammation, and mitochondrial deficiencies. Scientists have suggested that changes in organisms’ gut microbiota relate to specific gut phenotypes, while probiotics can be ingested to regulate chronic disease progression in conjunction with microbiota changes. However, more research is needed to understand how gut microbiota could be attributed … Continue reading The Effects of the Gut on Fruit Flies’ Lifespans

What Dominates in Shaping Human Gut Microbiota?

By Maryna Mullerman ‘20 The human microbiome is thought to be shaped by many factors. Daphna Rothschild and researchers from Weizmann Institute of Science in Israel attempted to find the most important   determinant for the microbial composition of the human gut. They compared genetic and environmental factors that were thought to influence gut composition and utilized statistical measures to analyze them. The study recruited 1046 … Continue reading What Dominates in Shaping Human Gut Microbiota?

The Roles of Human Gut Inhabitants in Infant Development

By Maryna Mullerman ’20 Farzana Yasmin and researchers from the University of Alberta in Canada analyzed how microbial systems in infant guts change over time, as well as how they can be affected by perinatal factors such as antibiotics, formula feeding, and birth mode. The study would reveal the importance of tracking variations in microbial community during early life stages. The researchers collected data from … Continue reading The Roles of Human Gut Inhabitants in Infant Development
