The transcriptional and translational landscape of HCoV-OC43 infection.
PLoS Pathog
January 2025
Discovery Research Platform for Hidden Cell Biology, University of Edinburgh, Edinburgh, Scotland, UK.
The coronavirus HCoV-OC43 circulates continuously in the human population and is a frequent cause of the common cold. Here, we generated a high-resolution atlas of the transcriptional and translational landscape of OC43 during a time course following infection of human lung fibroblasts. Using ribosome profiling, we quantified the relative expression of the canonical open reading frames (ORFs) and identified previously unannotated ORFs.

Weibel-Palade bodies (WPB) are secretory organelles exclusively found in endothelial cells and among other cargo proteins, contain the hemostatic von-Willebrand factor (VWF). Stimulation of endothelial cells results in exocytosis of WPB and release of their cargo into the vascular lumen, where VWF unfurls into long strings of up to 1000 µm and recruits platelets to sites of vascular injury, thereby mediating a crucial step in the hemostatic response. The function of VWF is strongly correlated to its structure; in order to fulfill its task in the vascular lumen, VWF has to undergo a complex packing/processing after translation into the ER.

Canopy family proteins are highly sequence-conserved proteins with an N-terminal hydrophobic signal sequence, a unique pattern of six cysteine residues characteristic of the saposin-like proteins, and a C-terminal putative endoplasmic reticulum retention signal sequence. At present, the known canopy family proteins are canopy fibroblast growth factor signaling regulator 1 (CNPY1), CNPY2, CNPY3, and CNPY4. Despite similar structures, canopy family proteins regulate complex signal networks to participate in various biological processes.

Department of Anatomy, School of Basic Medical Sciences, Shanxi Medical University, No 56, Xinjian Nan Road, Taiyuan, 030001, Shanxi, China.
The integrity of the myelin sheath of the spinal cord (SC) is essential for motor coordination. Seipin is an endoplasmic reticulum transmembrane protein highly expressed in adipose tissue and motor neurons in the SC. It was reported Seipin deficiency induced lipid dysregulation and neurobehavioral deficits, but the underlying mechanism, especially in SC, remains to be elucidated.

Breast cancer (BC) is a malignant tumor that occurs in breast tissue. This project aims to predict the prognosis of BC patients using genes related to hypoxia and endoplasmic reticulum stress (ERS). RNA-seq and clinical data for BC were downloaded from TCGA and GEO databases.
