Research Article: Genetic Drift Assessment of Cancer Cell Lines in Pharmacogenomic Studies

Image Source: https://doi.org/10.1016/j.cels.2020.08.012 By: Benison Zerrudo Genetic variation can be linked to pharmacological response using cell line model systems, but biomedical research faces dilemma when using these cell lines due to unstable genes and misidentification. Genomic instability can influence the reproducibility of research experiments that use cancer cell lines. These issues are common, and guidelines … Continue reading Research Article: Genetic Drift Assessment of Cancer Cell Lines in Pharmacogenomic Studies

Research Highlights: Gut Microbiome Play A Role In Resistance to Viral Infection

Image Source: https://doi.org/10.1016/j.cell.2020.10.047 Original Article: https://doi.org/10.1016/j.cell.2020.10.047 Interferons (IFN-I) are proteins that play a role in antiviral immunity. Interferons are naturally occurring substance that inhibits the ability of viruses to replicate. Interferons can also improve the immune system. However, the source of IFN-I signaling under homeostatic conditions is not well understood. Researchers discovered that commensal bacteria … Continue reading Research Highlights: Gut Microbiome Play A Role In Resistance to Viral Infection

Research Highlights: Hyperbaric Oxygen Therapy May Help Increase Cell Life and Remove Senescent Immune Cells in Older Adults

Source: https://jabsom.hawaii.edu/ Original Article: https://doi.org/10.18632/aging.202188 As we age, physiological activities in our body decrease. Shortening of the telomere length and cellular senescence are associated with the aging process. Telomeres are repetitive DNA sequences at the end of chromosomes which serves as protection. Each cell division, the telomeres become shorter. Cells can no longer divide when … Continue reading Research Highlights: Hyperbaric Oxygen Therapy May Help Increase Cell Life and Remove Senescent Immune Cells in Older Adults

Counting Neurotransmitter Molecules in the Brain
