Addressing overlapping sample challenges in genome-wide association studies: Meta-reductive approach.

Polygenic risk scores (PRS) are instrumental in genetics, offering insights into an individual level genetic risk to a range of diseases based on accumulated genetic variations. These scores rely on Genome-Wide Association Studies (GWAS). However, precision in PRS is often challenged by the requirement of extensive sample sizes and the potential for overlapping datasets that can inflate PRS calculations.

SARS-COV-2 as potential microRNA sponge in COVID-19 patients.

Background: MicroRNAs (miRNAs) are a class of small non-coding RNA that can downregulate their targets by selectively binding to the 3' untranslated region (3'UTR) of most messenger RNAs (mRNAs) in the human genome. MiRNAs can interact with other molecules such as viruses and act as a mediator for viral infection. In this study, we examined whether, and to what extent, the SARS-CoV-2 virus can serve as a "sponge" for human miRNAs.

Enterovirus71 virus-like particles produced from insect cells and purified by multistep chromatography elicit strong humoral immune responses in mice.

Aims: The study aims to develop a novel multistep chromatographic purification process for human enterovirus71 virus-like particles (VLPs) produced from insect cells (Sf9) infected with recombinant baculovirus.

Methods And Results: Sf9 cells were maintained in the Wave Bioreactor system 20/50, and harvested when the viability decreased to 75% after infected with Bac-P1-3CD at the multiplicity of infection (MOI) of 1. After sonication and centrifugation, EV71 VLPs were purified with Capto(™) Core 700, Capto(™) adhere and Capto(™) butyl.

Expression and characterization of hepatitis E virus-like particles and non-virus-like particles from insect cells.

The hepatitis E virus (HEV) capsid antigen expressed in insect cell has been proposed as a candidate subunit vaccine for the prevention of hepatitis E. However, the expression and purification of HEV virus-like particles (VLPs) from insect cells have not been explored. We aimed to optimize the procedure to obtain HEV VLPs.
