University of Utah, Salt Lake City, UT, USA.
Background: Neurodegenerative disorders such as Alzheimer's Disease (AD) are increasingly associated with irregular lipid accumulation. Dysfunction in the catabolism of sphingolipids leads to many neurodegenerative disorders but has only recently garnered interest in AD. Excess ceramide deposition has been observed in Aβ-plaques, plasma, and cerebrospinal fluid in AD patients and AD mouse models.

Background: We identified the missense variant Ser1038Cys (rs377155188) in the tetratricopeptide repeat domain 3 (TTC3) gene that segregate in a non-Hispanic white late onset Alzheimer disease (LOAD) family. This variant is predicted to be deleterious and extremely rare (MAF<0.01%).

Background: As a prevalent and deadly malignant tumor, the treatment outcomes for late-stage patients with cervical squamous cell carcinoma (CSCC) are often suboptimal. Previous studies have shown that tumor progression is closely related with tumor metabolism and microenvironment reshaping, with disruptions in energy metabolism playing a critical role in this process. To delve deeper into the understanding of CSCC development, our research focused on analyzing the tumor microenvironment and metabolic characteristics across different regions of tumor tissue.

Long-distance migrants must optimise their timing of breeding to capitalise on resources at both breeding and over-wintering sites. In species with protracted breeding seasons, departing earlier on migration might be advantageous, but is constrained by the ongoing breeding attempt. Here we investigated how breeding timing affects migratory strategies in the Manx shearwater (Puffinus puffinus), a trans-hemispheric migratory seabird with large temporal variation in the onset of breeding.
