Research Overview

Janakraj Bhattrai studies how early-life stress and genetic manipulation can protect against or reveal disease mechanisms. His work ranges from showing that mild stress in young organisms activates protective genes that guard against Alzheimer's-like damage later in life, to developing better zebrafish models that let researchers identify disease-causing genes more efficiently. Together, these projects suggest that understanding cellular stress responses and having the right experimental tools can unlock new ways to prevent age-related diseases.

Plain English
Researchers exposed young worms to mild stress during development, which triggered changes in how their cells read their genes. These early-life changes activated a protein called HSF-1 that rewired the worms' fat metabolism and protected their cells from damage caused by amyloid proteins—the toxic clumps linked to Alzheimer's disease—when they got older. This matters because it shows that brief stressful experiences early in life can create lasting protection against age-related diseases by fundamentally changing how the body processes fats and manages cellular damage.

Effective Generation of Gynogenic Haploid Zebrafish Embryos Using Low Dosage of UV Rays.

Plain English
Researchers found a way to create zebrafish with only one copy of each gene (instead of the normal two) by using a gentler dose of UV radiation on sperm, which keeps more of these embryos alive and healthy compared to previous methods. Normally, these single-copy embryos die in large numbers and develop severe abnormalities that make it impossible to study what individual genes actually do. This breakthrough means scientists can now use zebrafish to quickly identify which genes cause specific diseases by screening thousands of these special embryos—something that wasn't possible before.
