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 expression to change in response to mechanical stress. The researchers corroborated this result with in vivo work by performing immunohistochemical assays on control and malignant tissue cores from bronchi of lung cancer patients. The HALO Tissue Classifier Add-on was used to classify epithelium, stroma, and tumor within the tissue cores and the Cytonuclear IHC module was used to quantify cytoplasmic PFKP staining in bronchial epithelium.

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 and autophagy-related proteins LC3A/B that are associated with breast cancer subtype and survival. The mechanism(s) by which Kaiso promotes tumor progression will require future investigation.
