Lfng-expressing centroacinar cell is a unique cell-of-origin for p53 deficient pancreatic cancer. (PubMed, Oncogene)

Finally, high LFNG expression is associated with high grade and poor survival in human patients. Taken together, Lfng marks a centroacinar subpopulation that is uniquely susceptible to oncogenic transformation when p53 is lost, and Lfng functions as an oncogene in all three lineages of the exocrine pancreas.

Tumor immunogenicity regulates host immune responses, and conventional dendritic cell type 2 uptakes the majority of tumor antigens in an orthotopic lung cancer model. (PubMed, Cancer Immunol Immunother)

The majority of ZsGreen conjugated with minOVA was observed in the conventional type 2 DCs (cDC2), whereas cDC1 has minimal. These data indicate that tumor immunogenicity regulates host immune responses, and tumor neoantigen is mostly recognized by cDC2 cells, which may play a critical role in initiating antitumor immune responses in an orthotopic murine lung cancer model.

In conclusion, 17p13 deletions were most commonly seen in p53 negative cancers, supporting their role as a cause for the p53 null phenotype in urothelial cancer. The association of 17p13 deletions with high grade and advanced pT stage may reflect increasing genomic instability going along with stage and grade progression.

In contrast, dppe silver drugs induced paraptosis, a novel recently described form of programmed cell death. Together with the good tumor specificity of this compound's class, this work suggests that dppe-containing silver complexes could be interesting drug candidates for the treatment of resistant ovarian cancer.

The Incidence of FISH Abnormalities in Patients with Post-Transplant Lymphomas (PT-NHLs) (USCAP 2024)

FISH analysis of FFPE PT-NHLs detects genetic abnormalities, even in small specimens, in approximately 60% of cases. While BCL2 and BCL6 abnormalities are infrequent, MYC and 11q abnormalities were seen in 1/3 of tested cases. Interestingly, the classic 11q aberration was seen only in GC-DLBCLs (all patients alive), while extra copies were seen in non-GC cases (all patients with follow-up have died), including 2 EBV positive, suggesting different pathogenetic pathways with unique biologic behavior.
