Molecular biology explores the tiny machinery inside living cells, revealing how genetic instructions are read, copied, and turned into the proteins that keep us alive. This field acts as a bridge between the static code of DNA and the dynamic processes that drive growth, disease, and life itself, offering insights into everything from cellular repair to the development of new medicines.

On Gist.Science, we track every new preprint uploaded to bioRxiv in this category to make these complex discoveries accessible to everyone. Our team processes each submission to provide both clear, plain-language explanations and detailed technical summaries, ensuring you can grasp the core findings without getting lost in dense academic jargon.

Below are the latest molecular biology papers freshly processed from bioRxiv, ready for you to explore and understand.

Long-term stability of RNA nucleoside standards for accurate LC-MS quantification

This study systematically evaluates the 12-month stability of 44 RNA nucleoside standards stored at -80°C and -20°C, identifying specific degradation patterns and purity issues to establish practical guidelines for storage, quality control, and preparation that enhance the accuracy and reproducibility of LC-MS-based RNA modification analysis.

Identification of a microRNA with a mutation in the loop structure in the silkworm Bombyx mori

This study identifies a mutant miR-3260 with a loop structure deletion in a translucent-skinned silkworm strain, revealing that while the wild-type miRNA targets juvenile hormone-related genes, the loop mutation prevents Dicer-mediated cleavage yet fails to produce the expected phenotypic effects.

Identification of Parkinson's disease-associated regulatory variants in human dopaminergic neurons reveals modulators of SCARB2 and BAG3 expression

This study integrates multi-omics data and functional validation in human dopaminergic neurons to identify Parkinson's disease-associated regulatory variants that modulate SCARB2 and BAG3 expression by altering transcription factor binding and chromatin accessibility, thereby elucidating potential mechanisms underlying neuronal degeneration.

From Adipose to Limbus: Deciphering the Paracrine Effects of MSC Secretomes on Oxidative Stress-Induced RPE Dysfunction

This study demonstrates that secretomes derived from both adipose- and limbal-derived mesenchymal stem cells effectively protect oxidative stress-damaged retinal pigment epithelium cells by enhancing viability, modulating inflammation and apoptosis, and inhibiting pathological angiogenesis, thereby highlighting their potential as safe, cell-free therapies for retinal degeneration.
