Detection and enumeration of periodontopathogenic bacteria in subgingival biofilm of pregnant women

Brazilian Oral Research, 2012
The aim of this study was to use the fluorescence in situ hybridization (FISH) technique to test the hypothesis of qualitative and quantitative differences of 8 periodontopathogens between pregnant and non-pregnant women.

Detection of Individual RNA in Fixed Cells and Tissues by Chromogenic ISH

Bio-Protocol, 2020
Visualization of RNA molecules in situ helps to better understand the functions of expressed genes. Currently, most conventional in situ hybridization methods for visualization of individual RNAs are based on fluorescence detection.

Clinical, Histopathological, and Molecular Characterization of Pediatric MN1::ZNF341‐Associated Cancer

Pediatric Blood &Cancer, EarlyView.
ABSTRACT A lethal round‐cell malignancy with an MN1::ZNF341 fusion has recently been reported in three infants. Here, we describe four further tumors, three in newborns (including monozygotic twins), and one in an adolescent. Detailed clinical, radiological, and histopathological data differentiate these tumors from their main mimics, neuroblastoma and

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

Molecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Biological implications of deletion p53 by fluorescence in situ hybridization in multiple myeloma

Biomedical and Biotechnology Research Journal, 2022
Background: Multiple myeloma (MM) is a clonal plasma cell disorder characterized by heterogeneous complex genetic abnormalities. Due to the low proliferative index of plasma cells, conventional cytogenetic (CC) analysis is hampered in MM.

Spatial biology in cancer epigenetics

Molecular Oncology, EarlyView.
Spatial epigenomics combines molecular profiling with tissue architecture to reveal how gene regulation is organized within intact tissues. In cancer, these technologies uncover the mechanisms driving tumor heterogeneity and microenvironmental interactions, opening new opportunities for biomarker discovery and precision medicine.

Cytogenetic follow-up by karyotyping and fluorescence in situ hybridization: implications for monitoring patients with myelodysplastic syndrome and deletion 5q treated with lenalidomide

Haematologica, 2011
In patients with low and intermediate risk myelodysplastic syndrome and deletion 5q (del(5q)) treated with lenalidomide, monitoring of cytogenetic response is mandatory, since patients without cytogenetic response have a significantly increased risk of ...

The Price of Precision: A Critical Review of Molecular Diagnostics in Glioma, From Guidelines to Global Disparities

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Gliomas have undergone a profound redefinition over the past decade, transitioning from morphology‐based entities to biologically coherent diseases defined by molecular alterations. The 2021 WHO Classification of Tumors of the Central Nervous System and its 2022 update formalize this shift, establishing integrated diagnosis as the global ...

Drawback of chimerism analysis by XY-fluorescence in situ hybridization: Deception of a relapse

Indian Journal of Medical and Paediatric Oncology, 2020
Chimerism is monitored by various methods in posttransplant patients. Interphase fluorescence in situ hybridization (FISH) for XY (sex) chromosomes is one of the methods commonly employed.
