Abstract

fetched live from OpenAlex

Kinesins are microtubule-associated motors essential for intracellular transport, yet their roles in RNA regulation are still not well understood. Our lab previously identified KLP-20 as a novel interactor of the RISC complex (unpublished), with loss of KLP-20 disrupting miRNA-mediated gene silencing. Although KLP-20 expression is restricted to neurons, KLP-20 mutants display characteristic bumpy epidermal phenotype, suggesting a role in neuronal-epidermal communication. We hypothesize that KLP-20 may facilitate the transport of miRNA-RISC complexes from neurons to the epidermis, enabling non-autonomous signaling. Using the nematode C. elegans, we aim to define the role of KLP-20 in miRNA regulation and neuronal to epidermal communication.To address this, I generated numerous RNAi constructs to test candidate genes for suppression of the KLP-20 dependant bumpy epidermal phenotype, expressed miRNAs under an epidermal promoter to assess tissue-specific rescue, and investigated whether KLP-20 mediated miRNA regulation is dependant on miRNA regulatory machinery. This work will advance the understanding of kinesins in miRNA regulation, with implications for neurodegenerative diseases linked to disrupted miRNA pathways.

Not calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)

The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.

Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
