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.
By integrating multi-platform transcriptomics and membrane-aware proteomics, this study establishes a quantitative hierarchy of TRP channel expression in the adult mouse cortex, revealing that TRPML, TRPC, and TRPM subfamilies dominate while TRPA1 and TRPV1 remain below reliable detection thresholds.
This study demonstrates that WAVE2 and REST/NRSF regulate the expression of clustered genes, such as protocadherins and beta-globin, by maintaining heterochromatin organization through the deposition of H3K9me3 and the prevention of aberrant CTCF/cohesin accumulation.
This study identifies the transcriptional repressor Tex15 as a critical regulator of vomeronasal sensory neuron diversity, demonstrating that its absence disrupts the expression of specific pheromone receptors and abolishes male-male aggression behaviors in mice.
The authors developed a cost-effective, high-resolution Tm-guided exon-exon junction RT-PCR method that ensures variant-specific detection of RNA splice isoforms lacking distinguishable exonic regions by designing primers that enforce junction-dependent amplification through precise melting temperature constraints.
This study reports the discovery and near-atomic resolution structure of the CAGE complex, a conserved, ~1 MDa hollow protein assembly found across diverse prokaryotic and eukaryotic microbes, suggesting an ancient evolutionary origin and potential roles in cellular transport or homeostasis.
This paper presents a non-invasive protocol for determining the sex of various coleoid cephalopod species as early as three hours post-hatching by utilizing skin swabs and quantitative PCR.
This study reveals that in metazoans, the DNA helicase activation required for chromosome replication relies on the cooperative function of MCM10 and SLD-2/RECQL4, a mechanism whose disruption leads to synthetic lethality and is linked to human disease syndromes.
This study identifies TXNDC15 as a critical regulator of endoplasmic reticulum protein quality control that fine-tunes the E3-ubiquitin ligase MARCHF6 to selectively degrade excess membrane protein subunits while protecting ciliary proteins, thereby ensuring proper ciliogenesis and preventing Meckel-Gruber syndrome.
This study demonstrates that while ANGPTL3 inactivation lowers lipids independently of LDL receptor secretion, the proteolytic cleavage of ANGPTL3 and the presence of ANGPTL8 are essential for differentially inhibiting lipases to further reduce LDL-cholesterol, suggesting that dual-targeted therapies could offer superior cardiovascular benefits.
This study identifies DNA damage response proteins, particularly the helicase-like transcription factor HLTF, as key host factors that drive the formation of large internal deletions in HIV-1 proviruses, revealing a previously undescribed cellular defense mechanism that generates defective viral genomes.
