Jason Yongsheng Chan,et al, The Journal of Clinical Investigation, 2020
To molecularly characterize the rare and aggressive tumors known as angiosarcomas, Chan et al utilized a combination of transcriptomic immuno-oncology profiling with multiplex immunohistochemistry and immunofluorescence. HALO image analysis software was used for the quantification of PD-L1, CD68, CD8, FOXP3, CD15, and ERG. From these studies, three phenotypes of patients were identified according to etiology, anatomical origin, signaling pathways, and the tumor inflammation signature. These distinct biological phenotypes...

An ex vivo tumor fragment platform to dissect response to PD-1 blockade in cancer

HALO Publications, Immuno-oncology

March 16, 2021

Dr. Paula Voabil and colleagues used a patient derived tumor fragment platform to investigate immune responses immediately following PD-1 blockade. The Tissue Classifier Add-on and the Multiplex IHC module of HALO® were used in this publication to quantify immune biomarkers in the tumor and stroma, contributing to their conclusion that the ability of tumors to respond to PD-1 blockage correlates with the ability of intratumoral immune cells to be reactivated by the blockade....

Mechanical regulation of glycolysis via cytoskeleton architecture

HALO Publications, Oncology

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...

Natural killer cells in the human lung tumor microenvironment display immune inhibitory functions

HALO Publications, Immuno-oncology

March 16, 2021

Jules Russick, et al, Journal for ImmunoTherapy of Cancer, 2020
Natural killer (NK) cells are known to have cytotoxic effector functions in tumor immunosurveillance. More recently, evidence of a second potentially inhibitory or regulatory role have emerged. Here, Russick et al compared expression patterns of NK cells inside tumors to nontumoral NK cells to understand their inhibitory functions in the context of the non-small cell lung carcinoma (NSCLC) tumor microenvironment (TME). These studies identified a novel and specific...

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...

Early-onset impairment of the ubiquitin-proteasome system in dopaminergic neurons caused by α-synuclein

Chris McKinnon, et al, Acta Neuropathologica Communications, 2020
In this study, McKinnon et al identify overexpression of α-synuclein leading to catalytic impairment of the 26S proteosome in defined regions of rat brains. Brain tissue was fixed following α-synuclein overexpression for immunofluorescence studies of dopaminergic neurons which were quantified by the HALO image analysis platform. Future research will focus on characterizing the relationship between proteasome impairment and neurodegeneration....

Lisa H Tostanoski, et al, Nature Medicine, 2020
In this study led by researchers at Harvard Medical School, they report the first demonstration of prevention of severe clinical disease in a hamster model of SARS-CoV-2 that were provided with a single immunization of the adenovirus serotype 26 (Ad26) vaccine. The Ad26 vaccine utilizes a stabilized spike protein of the SARS-CoV-2 and in the United States this vaccine is commonly known as the Johnson and Johnson vaccine. This study,...
