Article Synopsis
  • - MASLD is a global health issue affecting around 30% of the population, caused by a mix of genetics, lifestyle, and environmental factors, posing challenges for treatment development due to patient variability.
  • - Creating effective therapeutic models is difficult because existing systems and animal models fail to fully reflect the complexities of MASLD progression, prompting the need for more precise experimental approaches.
  • - The study utilized a liver acinus microphysiology system (LAMPS) with patient-derived cells to explore the effects of the PNPLA3 genetic variant on MASLD and tested the drug resmetirom, revealing significant changes in liver cell behavior indicative of disease progression.

Article Synopsis
  • Metabolic dysfunction-associated steatotic liver disease (MASLD) affects about 30% of the global population, driven by a mix of genetic, lifestyle, and environmental factors, complicating treatment and clinical trial design.* -
  • The study utilized a liver acinus microphysiology system (LAMPS) made from patient-derived cells to explore the effects of the PNPLA3 rs738409 genetic variant on MASLD progression, replicating various metabolic conditions.* -
  • Results showed that the PNPLA3 GG variant led to increased liver fat, immune activation, and pro-fibrotic factor secretion compared to wild type cells, providing insights for future treatments like resmetirom.*

Inhibitory control of excitatory networks contributes to cortical functions. Increasing evidence indicates that parvalbumin (PV+)-expressing basket cells (BCs) are a major player in maintaining the balance between excitation (E) and inhibition (I). Disruption of E/I balance in cortical networks is believed to be a hallmark of autism spectrum disorder (ASD).

Scientific reproducibility has been at the forefront of many news stories and there exist numerous initiatives to help address this problem. We posit that a contributor is simply a lack of specificity that is required to enable adequate research reproducibility. In particular, the inability to uniquely identify research resources, such as antibodies and model organisms, makes it difficult or impossible to reproduce experiments even where the science is otherwise sound.
