  • Thus, we report here the first characterization of activating and inactivating mutations in eelLHR and we show that these mutations have similar effects as those reported for mammalian LHRs. (preprints.org)
  • ATM mutation was significantly associated with higher tumor stage (p=0.012) and shorter overall survival (OS) (p=0.041). (preprints.org)
  • Stage 3 and 4 patients with ATM mutations (p=0.023) had shorter OS, and FBXW7 mutation was significantly associated with shorter DFS (p=0.002). (preprints.org)
  • Thus, the local immunological milieu in tissue compartments forms the nature and magnitude of the host responses, i.e., frequencies of regulatory T cells (Tregs) vs. T-helper 17 (Th17) cells, amount of pro-inflammatory cytokines vs. anti-inflammatory cytokines, extent of neutrophilia and antigen-presenting-cell (APC) activation, among others.

  • We analyzed the mutation frequencies of common actionable genes and their association with clinicopathological characteristics and oncologic outcomes using targeted NGS. (preprints.org)
  • Can precancerous stem cells be risk markers for malignant transformation in the oral mucosa? (biomedcentral.com)
  • Although overt inflammatory responses play a major role in malignant transformation of host cells following an infection, it is a disbalanced immune responses, which contribute to drive malignant transformation. (frontiersin.org)
  • Interaction between stromal cells and acute myeloid leukemia (AML) cells in bone marrow (BM) is known to contribute importantly to chemoresistance and disease recurrence. (biomed.news)
  • Altogether, this study identifies a potential application of metformin in sensitizing AML cells to chemotherapy and unveils a novel mechanism by which metformin executes such effect via blocking the mitochondrial transfer from stromal cells to AML cells. (biomed.news)
  • Epithelial cells have a specific microscopic structure with different lateral , apical, and basal membrane domains. (amboss.com)
