Lymphatic disruption drives lung transplant fibrosis through interleukin-1–mediated hyaluronan accumulation Interleukin-1–mediated hyaluronan synthesis in transplanted grafts promotes fibrotic remodeling because of lymphatic disruption.

New work deciphers how disruptions to #lymphatic drainage drive fibrosis in transplanted lungs and hearts through the accumulation of hyaluronan—and identifies potential therapeutic targets to prevent lung fibrosis in mice. #ScienceTranslationalMedicine https://scim.ag/3ONyh7H

Color photograph of Joan Steitz (Joan Argetsinger Steitz), the distinguished American molecular biologist and biochemist renowned for her groundbreaking discoveries in RNA biology, including the identification of small nuclear ribonucleoproteins (snRNPs) essential to RNA splicing. She is pictured in a close-up portrait within a laboratory or research setting, smiling warmly and directly at the camera with an engaging, approachable expression that conveys enthusiasm and expertise. Steitz has gray hair pulled back, striking blue eyes, and is wearing large, elaborate dangling earrings adorned with purple gemstones and metallic accents. She is dressed in a rich purple blouse. The softly blurred background includes scientific elements such as lab benches, equipment, monitors, charts, and partial signage, evoking the environment of her long career at Yale University where she served as Sterling Professor of Molecular Biophysics and Biochemistry. #JoanSteitz #MolecularBiology #WomenInScience #Biochemistry #RNA

Biochemist/molecular biologist Joan Steitz was born #OTD in 1941.

She (& team) figured out how our cells read/use genetic instructions to make proteins. A key person who helped crack the code on RNA—the molecule that acts like a messenger between DNA & and the proteins our bodies need. #WomenInSTEM

Subcellular depletion of importin β1 impairs presynaptic local translation and spatial memory Axonal localization of importin β1 is required for presynaptic functions that support spatial memory tasks.

Scientists have mapped out an importin-based pathway that enables neurons to maintain synaptic plasticity and spatial memory despite their unusually elongated shape.

DROSHA, DICER, and damage-induced long ncRNA control BMI1-dependent transcriptional repression at DNA double-strand break Genes near DNA double-strand breaks are silenced through a BMI1-dependent mechanism, while transcription of damage-induced lncRNAs (dilncRNAs), processed by DROSHA and DICER, occurs at break sites. Esposito and Capozzo et al. reconcile these opposing events, showing that the dilncRNA-DROSHA-DICER axis directs BMI1 recruitment, chromatin remodeling, and gene repression.

Actin cage for the synaptic vesicle liquid phase Brodin and Shupliakov demonstrate that synaptic activity triggers the formation of an actin cage that encapsulates the synaptic vesicle cluster. Disruption of this cage leads to the detachment of the cluster from the release site. These findings explain how the synaptic vesicle liquid phase can remain in place during activity.
