Dopaminergic neuronal dysfunction induced by newer generation systemic insecticides in Caenorhabditis elegans

Preprint · 2026 Summary While a growing number of studies have linked environmental exposures and Parkinson’s disease (PD) 1–3 , the impact of many pesticides remains understudied 4,5 ; for example, neonicotinoids are the most used insecticides in the world, b ... Full text Cite

Live visualization of extracellular matrix dynamics during development and regeneration in zebrafish.

Preprint · November 3, 2025 Extracellular matrix (ECM) plays fundamental roles in animal development, regeneration, and disease. The difficulty of tagging endogenous matrix proteins in vertebrates has limited the understanding of ECM composition and dynamics in complex tissues. To vi ... Full text Link to item Cite

Specialized high-capacity mitochondria fuel cell invasion.

Preprint · May 3, 2025 Cell invasion through basement membrane (BM) is energetically intensive, and how an invading cell produces high ATP levels to power invasion is understudied. By generating 20 endogenously tagged mitochondrial proteins, we identified a specialized mitochond ... Full text Link to item Cite

Programmed mitophagy at the oocyte-to-zygote transition promotes species immortality.

Preprint · April 9, 2025 The quality of mitochondria inherited from the oocyte determines embryonic viability, metabolic health throughout progeny lifetime, and future generation endurance. High levels of endogenous reactive oxygen species and exogenous toxicants are threats to mi ... Full text Link to item Cite

The actin protrusion deforms the nucleus during invasion through basement membrane.

Preprint · March 14, 2025 UNLABELLED: Cell invasion through basement membrane (BM) extracellular matrix barriers is important during organ development, immune cell trafficking, and cancer metastasis. Here we study an invasion event, anchor cell (AC) invasion, which occurs during Ca ... Full text Link to item Cite

Mitophagy at the oocyte-to-zygote transition promotes species immortality.

Preprint · February 3, 2025 The quality of inherited mitochondria determines embryonic viability 1 , metabolic health during adulthood and future generation endurance. The oocyte is the source of all zygotic mitochondria 2 , and mitochondrial health is under strict developmental regu ... Full text Link to item Cite

Increased in vivo transduction of AAV-9 cargo in Alport podocytes

Preprint · 2025 Alport syndrome is a rare genetic disorder characterized by progressive kidney disease, hearing loss, and eye abnormalities. Gene therapy for Alport syndrome has not yet been realized due to technical challenges, including effective transduction of target ... Full text Cite

A complete collagen IV fluorophore knock-in toolkit reveals α-chain diversity in basement membrane

Preprint · 2024 The type IV collagen triple helix, composed of three ⍺-chains, is a core basement membrane (BM) component that assembles into a network within BMs. Endogenous tagging of all ⍺-chains with genetically encoded fluorophores has remained elusive, limiting o ... Full text Cite

Reciprocal discoidin domain receptor signaling strengthens integrin adhesion to connect adjacent tissues.

Preprint · July 2023 Separate tissues connect through adjoining basement membranes to carry out molecular barrier, exchange, and organ support functions. Cell adhesion at these connections must be robust and balanced to withstand independent tissue movement. Yet, how cells ach ... Full text Cite

Reciprocal discoidin domain receptor signaling strengthens integrin adhesion to connect adjacent tissues

Preprint · June 12, 2023 AbstractSeparate tissues connect through adjoining basement membranes to carry out molecular barrier, exchange, and organ support functions. Cell adhesion at these connections must be robust and balanced to withsta ... Full text Cite

Chronic high-sugar diet in adulthood protects Caenorhabditis elegans from 6-OHDA induced dopaminergic neurodegeneration

Preprint · 2023 Background Diets high in saturated fat and sugar, termed ‘western diets’, have been associated with several negative health outcomes, including increased risk for neurodegenerative disease. Parkinson’s Disease (PD) is the second most prevalent ne ... Full text Cite
