Mechanical regulation of glycolysis via cytoskeleton architecture

Jin Suk Park,et al, Nature, 2020
Park and colleagues explored the question of how regulation of glycolysis responds to structural changes in tissue architecture and chose lung cells and tissue for their studies due to the regular mechanical stress experienced during respiration. In vitro studies demonstrated downregulation of glycolysis following a change in substrate via the degradation of the platelet isoform of the phosphofructokinase (PFKP) enzyme. In vitro studies also showed that oncogenic transformation changed the ability of PFKP...

Kaiso (ZBTB33) subcellular partitioning functionally links LC3A/B, the tumor microenvironment, and breast cancer survival

Sandeep K Singhal, et al, Communications Biology, 2021
Singhal and colleagues apply quantitative automated image analysis to investigate the role of a transcriptional regulator, Kaiso, in a diverse cohort of breast cancer tumors. Specifically, they utilized the Highplex FL Module with the Tissue Microarray Module of HALO to characterize the tumor microenvironment in breast cancer TMA cores, including pan-cytokeratin, PD-L1, CD8, and CD68. They found that cytoplasmic Kaiso is associated with an immune-suppressed tumor microenvironment and found novel connections between Kaiso...

Implementation of PD-L1 22C3 IHC pharmDxTM in Cell Block Preparations of Lung Cancer: Concordance with Surgical Resections and Technical Validation of CytoLyt® Prefixation

Si Kei Lou, et al, Acta Cytologica, 2020
In patients with advanced stage lung disease, it is beneficial to evaluate candidacy for immunotherapy without invasive biopsy testing. Lou et al performed a concordance study to evaluate formalin fixed cell blocks compared to lung tumor resections using a PD-L1 22C3 IHC pharmDx™ assay and found strong concordance between pathologists and HALO image analysis software. Future research will focus on clinical validation by assessing the clinical benefit from immunotherapy following PD-L1 immunohistochemistry on...

Cytonuclear FL

Cytonuclear FL measures the immunofluorescent positivity of an unlimited number of fluorescent markers in the nucleus or cytoplasm and reports the number of cells that are positive for each marker, the intensity score for each cell (0, 1+, 2+, 3+), and colocalization of different marker combinations. Optionally, the tool can output the complete table of cell data including individual cell sizes and intensity measurements for each dye in each cellular compartment. In the dual stained mouse pancreas shown above, the...
