      Postdoctoral position to study Polo kinase and centrosome abnormalities in cancer and other diseases job with National Cancer Institute, National Institutes of Health – (Jobs)

      0


      A postdoctoral fellowship is available to study the function of mammalian polo-like kinase 4 and 1 (Plk4 and Plk1), which play central roles in regulating various biological events, including centriole duplication, bipolar spindle formation, chromosome segregation, cell division, and proliferation. Dysregulation of Plk4/Plk1-dependent processes, by mutations in their associated cellular components or HIV accessory proteins, is tightly linked to the development of aneuploidy and cancer. During the past several years, we have been taking cell biological, biochemical, biophysical, and structural approaches (e.g., super-resolution imaging, single molecule tracking, in vitro reconstitution, X-ray crystallography, and cryo-EM) to delineate the molecular bases and structural rules governing the centrosomal architecture and function, the deregulation of which can lead to the development of various human diseases, including cancers, microcephaly, and AIDS.  For additional information, please visit https://ccr.cancer.gov/staff-directory/kyung-s-lee.

      To apply, please send a CV and three names of references to Dr. Kyung Lee (kyunglee@mail.nih.gov).

      Changes in Access to Comprehensive Clinical Microbiology Laboratory Testing in Tennessee From 2019-2024 – Research



      Background:

      Timely clinical microbiology laboratory testing is crucial for effective infectious disease management, impacting antibiotic selection, patient outcomes, and health care costs. This study aimed to evaluate changes in geographic access to comprehensive (Tier 1) clinical microbiology laboratories in Tennessee between 2019 and 2024.


      Methods:

      With the help of the Tennessee Department of Health, Tier 1 microbiology laboratories in Tennessee were identified for both 2019 and 2024. Catchment areas were calculated using a 25-mile drive-time radius around each laboratory. Changes in the number and location of Tier 1 laboratories were quantified, and demographic data were compared between laboratories that stayed open and those that closed.


      Results:

      The number of Tier 1 microbiology laboratories in Tennessee decreased by 38% over the 5-year period, and this resulted in a 35% decrease in square-mile coverage across the state. Covariates associated with laboratory closure included rurality, lower income, higher poverty, race, higher disability, and less education.


      Conclusions:

      A substantial decline in the number of Tier 1 clinical microbiology laboratories in Tennessee between 2019 and 2024 has decreased local access to comprehensive testing in areas with at-risk patient populations. This may have implications for timely diagnosis, appropriate antimicrobial therapy, and, ultimately, patient outcomes. Further research is needed to evaluate the clinical and economic consequences of these changes in laboratory access.


      Keywords:

      clinical microbiology; geographic access; health equity; laboratory consolidation; social determinants of health.

      Scientists Drill 523 Meters Through Antarctic Ice, Uncovering 23 Million Years of Climate Secrets – Science News



      Blue Ice Crack Frozen WallsDeep beneath Antarctica’s ice, scientists have uncovered a geological archive that could reshape predictions of future sea-level rise. Working roughly 700 kilometers from the closest Antarctic research stations, the team drilled through 523 meters of solid ice at Crary Ice Rise, located along the edge of the West Antarctic Ice Sheet. Beneath the ice, they […]

      Ancient DNA Uncovers Chilling Truth Behind Europe’s Prehistoric Mass Killing – Science News



      Iron Age Massacre Burial EventA 2,800-year-old mass grave in Serbia reveals a chilling pattern: women and children deliberately targeted, most unrelated to one another, and buried in a ritualized ceremony. New research suggests that women and children were intentionally singled out in one of the largest known prehistoric mass killings in Europe. Excavations at the Gomolava burial site in […]

      Brain Blood Flow May Predict Alzheimer’s Risk Before Memory Loss – Science News



      Amyloid Plaques Dementia Brain Neurons Alzheimer's DiseaseNew noninvasive tools reveal that subtle shifts in brain blood flow and oxygen use may mirror key markers of Alzheimer’s risk. Small shifts in how blood circulates through the brain and how brain cells use oxygen could signal a higher risk of Alzheimer’s disease, according to researchers at the Mark and Mary Stevens Neuroimaging and […]

      “Ghost Galaxy” Made of 99% Dark Matter Discovered 300 Million Light Years Away – Science News



      Dark Galaxy CDG 2 Near Perseus ClusterAstronomers have detected a ghostly galaxy that is almost completely made of dark matter. The faint object was revealed by just four globular star clusters hiding in the Perseus cluster. While most galaxies blaze with billions of stars, a rare few are so faint they are barely detectable. These low-surface-brightness galaxies contain very few stars […]

      Spatial transcriptomics and single-cell analysis reveal GSTO2-mediated protective networks in oral squamous cell carcinoma tumor microenvironment – Research



      Background:

      Oral squamous cell carcinoma (OSCC) exhibits significant cellular heterogeneity and metabolic reprogramming that influence tumor progression and therapeutic responses. However, the molecular mechanisms underlying these processes remain poorly understood.


      Methods:

      We performed an integrated analysis of single-cell RNA sequencing and spatial transcriptomics analysis on OSCC samples to characterize cellular heterogeneity and identify key regulatory factors. Summary-data-based Mendelian randomization (SMR) analysis was conducted to establish causal links between gene expression and OSCC risk. Functional enrichment, protein-protein interaction (PPI) network analysis, molecular docking, and co-immunoprecipitation (Co-IP) were employed to elucidate molecular mechanisms.


      Results:

      Single-cell analysis of 50,667 cells identified nine distinct cell populations with epithelial cells showing the highest glutamine metabolism activity. SMR analysis revealed glutathione S-transferase omega 2 (GSTO2) as a genetically validated protective factor for OSCC risk. GSTO2-positive epithelial cells exhibited enhanced metabolic reprogramming, particularly in fatty acid degradation and amino acid catabolism pathways. Spatial transcriptomics demonstrated that GSTO2-positive cells were spatially organized and showed enhanced communication with immune cells. Protein-protein interaction analysis identified interferon-stimulated genes (MX1, OAS1, UBE2L6) and immunoproteasome subunits (PSMB8, PSMB9) as core regulatory hubs. Molecular docking confirmed direct binding interactions between GSTO2 and these hub proteins, with MX1-GSTO2 showing the strongest binding affinity (-10.7 kcal/mol). Co-immunoprecipitation experiments validated the physical interaction between GSTO2 and MX1.


      Conclusions:

      This study indicates that GSTO2 defines an epithelial subset characterized by enhanced metabolic activity and immune interactions, highlighting its potential as a biomarker and therapeutic target in OSCC.
